NOAA presented to the U.S. Coast Guard today a new report that finds that 36 sunken vessels scattered across the U.S. seafloor could pose an oil pollution threat to the nation’s coastal marine resources. Of those, 17 were recommended for further assessment and potential removal of both fuel oil and oil cargo.

The sunken vessels are a legacy of more than a century of U.S. commerce and warfare. They include a barge lost in rough seas in 1936; two motor-powered ships that sank in separate collisions in 1947 and 1952; and a tanker that exploded and sank in 1984. The remaining sites are 13 merchant marine ships lost during World War II, primarily along the Atlantic Seaboard and Gulf of Mexico. To see a list of the ships and their locations, visit: http://sanctuaries.noaa.gov/protect/ppw/.

The report, part of NOAA’s Remediation of Underwater Legacy Environmental Threats (RULET) project, identifies the location and nature of potential sources of oil pollution from sunken vessels. Knowing where these vessels are helps oil response planning efforts and may help in the investigation of reported mystery spills--sightings of oil where a source is not immediately known or suspected. “This report is the most comprehensive assessment to date of the potential oil pollution threats from shipwrecks in U.S. waters,” said Lisa Symons, resource protection coordinator for NOAA’s Office of National Marine Sanctuaries. “Now that we have analyzed this data, the Coast Guard will be able to evaluate NOAA’s recommendations and determine the most appropriate response to potential threats.”

“The Coast Guard is pleased to receive these risk assessments from our partner agency NOAA and looks forward to our continued coordination on the matter of potential pollution associated with sunken vessels in U.S. waters,” said Capt. John Caplis, the Coast Guard’s chief of marine environmental response. “Coast Guard federal on-scene coordinators receiving the risk assessments will carefully review the data and incorporate it into their area contingency plans.”

In 2010, Congress appropriated $1 million for NOAA to develop a list of the most significant potentially polluting wrecks in U.S. waters, including the Great Lakes, specifically addressing ecological and socio-economic resources at risk. Those funds were not intended for oil or vessel removal.

NOAA maintains the internal Resources and UnderSea Threats (RUST) database of approximately 30,000 sites of sunken material, of which 20,000 are shipwrecks. The remaining items are munitions dumpsites, navigational obstructions, underwater archaeological sites, and other underwater resources.

Initial screening of these shipwrecks revealed 573 that could pose substantial pollution risks, based on the vessel’s age, type, and size. This includes vessels built after 1891, when U.S. vessels began using fuel oil; vessels built of steel; vessels over 1,000 gross tons, and any tank vessel.

Additional research about the circumstances of each vessel’s loss narrowed that number to 107 shipwrecks. Of those, some were deemed navigational hazards and demolished, and others were salvaged. Most of the 107 wrecks have not been directly surveyed for pollution potential, and in some cases little is known about their current condition.

To prioritize and determine which vessels are candidates for further evaluation, NOAA used a series of risk factors to assess the likelihood of substantial amounts of oil remaining onboard, and the potential ecological and environmental effects if that oil spills. Risk factors include the total oil volume onboard as cargo or fuel, the type of oil, and the nature of the sinking event. For example, a vessel that was struck by multiple torpedoes would likely contain less oil than a vessel that sank in bad weather.

After this third level of screening, 87 wrecks remained on the list developed for the Coast Guard’s area contingency plans. Among this group, NOAA determined that 36 shipwrecks are candidates for a “Worst Case” discharge event in which the shipwreck’s entire fuel oil and oil cargo would be released simultaneously, and recommended that 17 of these wrecks be considered for further assessment and feasibility of oil removal.

Six wrecks are potential candidates for a “Most Probable” discharge event, where a shipwreck could lose approximately 10 percent of its fuel oil or oil cargo. To date, known oil discharges from shipwrecks are typically in the “Most Probable” category or smaller.

The report, including 87 risk assessments, is not intended to direct Coast Guard activities, but rather provide the Coast Guard with NOAA’s scientific and technical assessment and guidance as a natural resource and cultural heritage trustee.

The Coast Guard, as the federal On-scene Coordinator for mitigating oil spills in the coastal marine environment, the Regional Response Teams, and local Area Committees, as established under the Oil Pollution Act of 1990, will review and incorporate the assessments into regional and area marine environmental response contingency plans. The individual risk assessments not only highlight concerns about potential ecological and socio-economic impacts, but also characterize most of the vessels as historically significant and many of them as grave sites, both civilian and military.

Funding for any assessment or recovery operations determined to be necessary is dependent upon the unique circumstances of the wreck. If a wreck still has an identifiable owner, that owner is responsible for the cost of cleanup. Coast Guard officials say that if no responsible party exists, the Oil Spill Liability Trust Fund would likely be accessed.

As America’s maritime first responder, the Coast Guard protects those on the sea, protects our nation from threats delivered by sea, and protects the sea itself. By executing our marine environmental protection responsibilities, the Coast Guard reduces the risk of harm to the marine environment by developing and enforcing regulations to prevent and respond to maritime oil spills and hazardous substance releases.

New website features millions of chemical analyses from Deepwater Horizon oil spill

September 12, 2013

NOAA announced the release yesterday of a comprehensive, quality-controlled dataset  that gives ready access to millions of chemical analyses and other data on the massive Deepwater Horizon Oil Spill. The dataset, collected to support oil removal activities and assess the presence of dispersants, wraps up a three year process that began with the gathering of water samples and measurements by ships in the Gulf of Mexico during and after the oil release in 2010. 

NOAA was one of the principal agencies responding to the Macondo well explosion in the Gulf of Mexico, and is the official ocean data archivist for the federal government. While earlier versions of the data were made available during and shortly after the response, it took three years for NOAA employees and contractors to painstakingly catalog each piece of data into this final form.

This Deepwater Horizon Oil Spill dataset, including more than two million chemical analyses of sediment, tissue, water, and oil, as well as toxicity testing results and related documentation, is available to the public online at: http://www.nodc.noaa.gov/deepwaterhorizon/specialcollections.html.

A companion dataset, including ocean temperature and salinity data, currents, preliminary chemical results and other properties collected and made available during the response can be found at: http://www.nodc.noaa.gov/deepwaterhorizon/insitu.html.

The Deepwater Horizon Oil Spill response involved the collection of an enormous dataset. The underwater plume of hydrocarbon -- a chemical compound that consists primarily of the elements carbon and hydrogen -- was a unique feature of the spill, resulting from a combination of high-pressure discharge from the well near the seafloor and the underwater application of chemical dispersant to break up the oil. 

“The size and scope of this project -- the sheer number of ships and platforms collecting data, and the broad range of data types -- was a real challenge. In the end, it was a great example of what can be accomplished when you bring together the expertise across NOAA, making this quality-controlled information easily available to the general public for the first time,” said Margarita Gregg, Ph. D., director of the National Oceanographic Data Center, which is part of NOAA's Satellite and Information Service.

The effort to detect and track the plume was given to the Deepwater Horizon Response Subsurface Monitoring Unit (SMU), led by NOAA’s Office of Response and Restoration, and included responders from many federal and state agencies and British Petroleum (BP). Between May and November 2010, the SMU coordinated data collection from 24 ships on 129 cruises.  

The SMU data archived at NOAA’s National Oceanographic Data Center (NODC) is already being used by researchers at NOAA and in academia for a range of studies, including models of oil plume movement and investigations of subsurface oxygen anomalies. In addition to NODC, other parts of the NOAA archive system such as NOAA’s National Geophysical Data Center and the NOAA Central Library contain important holdings. Recently, the library‘s Deepwater Horizon Centralized Repository won recognition from the Department of Justice “as one of the best successes in the Freedom of Information Act (FOIA) world last year.”

By law, these data will remain available through NOAA’s archive systems for at least 75 years. Additional data from the Deepwater Horizon/Macondo spill can be found at the NOAA oil spill archive website: http://www.noaa.gov/deepwaterhorizon/ and data collected in the on-going Natural Resource Damage Assessment can be found at: http://www.gulfspillrestoration.noaa.gov/.

Sandy has been retired from the official list of Atlantic Basin tropical cyclone names by the World Meteorological Organization’s hurricane committee because of the extreme impacts it caused from Jamaica and Cuba to the Mid-Atlantic United States in October 2012.
Storm names are reused every six years for both the Atlantic and eastern North Pacific basins. If a storm is so deadly or costly that the future use of the name would be insensitive or confusing, the WMO hurricane committee, which includes personnel from NOAA’s National Hurricane Center, may retire the name. Sandy is the 77th name to be retired from the Atlantic list since 1954. The name will be replaced with “Sara” beginning in 2018.
Sandy was a classic late-season hurricane in the southwestern Caribbean Sea. The cyclone made landfall as a category 1 hurricane (on the Saffir-Simpson Hurricane Wind Scale) in Jamaica, and as a 115 mph category 3 hurricane in eastern Cuba.  Hurricane Sandy merged with a frontal system hours before making landfall as a post-tropical cyclone near Brigantine, N.J., and its size and strength caused catastrophic damage all along the mid-Atlantic shoreline.

Because of its tremendous size, Sandy drove a catastrophic storm surge into the New Jersey and New York coastlines. Preliminary U.S. damage estimates are near $50 billion, making Sandy the second-costliest cyclone since Katrina to hit the United States. There were at least 147 direct deaths recorded across the Atlantic basin due to Sandy, with 72 of these fatalities occurring in the mid-Atlantic and northeastern United States. Sandy caused the greatest number of U.S. direct fatalities related to a tropical cyclone outside of the southern states since Hurricane Agnes in 1972.

Mobile app provides free nautical charts for recreational boating

May 20, 2013

MyNOAACharts, a mobile app beta test for Android tablets, can easily integrate the user's location, the nautical chart, and all the navigational information from the U.S. Coast Pilot.

Download here (Credit: NOAA)

As recreational boaters gear up for a summer of fun on coastal waters and the Great Lakes, NOAA is testing MyNOAACharts, a new mobile application that allows users to download NOAA nautical charts and editions of the U.S. Coast Pilot. The app, which is only designed for Android tablets for the testing period, will be released on May 20.

MyNOAACharts, which can be used on land and on the water, has GPS built-in capabilities that allow users find their positions on a NOAA nautical chart. They can zoom in any specific location with a touch of the finger, or zoom out for the big picture to plan their day of sailing. The Coast Pilot has “geotagged” some of the major locations -- embedding geographical information, such as latitude and longitude, directly into the chart so it is readable in the app -- and provides links to appropriate federal regulations. The app can be downloaded from the Google Play™ app store.

“Easy and workable access to nautical charts is important for boating safety,” said Rear Admiral Gerd Glang, director of NOAA Office of Coast Survey. “I’ve seen a popular t-shirt that has a ‘definition’ of a nautical chart splayed across the front: ‘chärt, n: a nautical map that shows you what you just hit.’ As creative as that is, a boating accident can kill. Keeping a nautical chart on hand – to avoid hitting something – can save lives.”

The beta test for MyNOAACharts will expire this Labor Day, Sept. 2. Coast Survey will then evaluate usage and user feedback to decide whether to release a finished version of the app.

“Expanding the app across a multitude of platforms, ensuring easy accessibility to over a thousand charts and nearly 5,000 pages of U.S. Coast Pilot, will take considerable resources,” Glang said. “We can do it if the boating community likes the app. We truly want the users to let us know if the app meets their needs.”

Boaters without an Android tablet should not despair. The Office of Coast Survey provides free BookletCharts, which are 8 ½” x 11” PDF versions of NOAA nautical charts that can be downloaded and printed at home. The U.S. Coast Pilot is also available in a free PDF version. Those products, and information for purchasing other nautical products, are available at www.nauticalcharts.noaa.gov.

Important notice for commercial mariners: The mobile app MyNOAACharts and the BookletCharts do not fulfill chart carriage requirements for regulated commercial vessels under Titles 33 and 46 of the Code of Federal Regulations.

NOAA’s Office of Coast Survey, originally formed by President Thomas Jefferson in 1807, is the nation’s nautical chartmaker. Its hydrographers survey the coastal seafloor, respond to maritime emergencies and search for underwater dangers to navigation.

First GOES-R instrument ready to be installed onto spacecraft

May 2, 2013

The first of six instruments that will fly on GOES-R, NOAA’s next-generation of geostationary operational environmental satellites, has been completed seven months before its scheduled installation onto the spacecraft.

The instrument, the Extreme Ultraviolet and X-ray Irradiance Sensors, or EXIS, will provide forecasters at NOAA’s Space Weather Prediction Center with some of the most important early warnings of impending solar storms. It will also give scientists a more accurate measure of the extremes in solar energy radiating toward earth, which can severely disrupt telecommunications, air travel, and the performance of power grids.

“Severe space weather has the potential to cause significant damage to the U.S. and global economy, so it’s critical GOES-R has this technology in place as quickly as possible to monitor it,” said Mary Kicza, assistant administrator for NOAA’s Satellite and Information Service.

GOES-R, scheduled to launch in 2015, will be more advanced than NOAA’s current GOES fleet. The satellites are expected to more than double the clarity of today’s GOES imagery and provide more atmospheric observations than current capabilities with more frequent images. Data from the GOES-R instruments will be used to create many different products, enabling NOAA meteorologists and other users to better monitor the atmosphere, land, ocean and the sun, facilitating more timely and accurate forecasts and warnings.

The University of Colorado’s Laboratory for Atmospheric and Space Physics (LASP) built and tested EXIS.

EXIS will be shipped from the LASP site in Boulder to Lockheed Martin Space Systems Co. in Littleton, Colo., later this year to be installed onto the spacecraft. Lockheed is building the GOES-R spacecraft.

The remaining GOES-R instruments to be delivered are:

the Advanced Baseline Imager, the primary instrument on GOES-R for imaging Earth’s weather, climate, and environment;Geostationary Lightning Mapper, which will provide for the first time a continuous surveillance of total lightning over the western hemisphere from space;the Space Environment In-Situ Suite, which consists of sensors that will monitor radiation hazards that can affect satellites and communications for commercial airline flights over the poles; the Solar Ultraviolet Imager, a high-powered telescope that observes the sun, monitoring for solar flares and other solar activity that could impact Earth, andthe Magnetometer, which will provide measurements of the space environment magnetic field that controls charged particle dynamics in the outer region of the magnetosphere. These particles can be dangerous to spacecraft and human spaceflight.

 NOAA manages the GOES-R Series Program through an integrated NOAA-NASA program office, staffed with personnel from NOAA and NASA, and co-located at NASA’s Goddard Space Flight Center in Greenbelt, Md.

“We’re just a few years away from seeing significant improvements in the way NOAA will serve the public with even better weather forecasts and warnings,” said Greg Mandt, director of the GOES-R Series Program..

Partners deploy underwater robots to improve hurricane science

September 9, 2013

A fleet of underwater robots is descending into waters off the east coast to collect data that could help improve storm intensity forecasts during future hurricane seasons. Several regions of the NOAA-led U.S. Integrated Ocean Observing System (IOOS®) are partnering to deploy 12 to 16 autonomous underwater robotic vehicles, also known as gliders, from Nova Scotia to Georgia.  

The gliders will be available through the peak fall Atlantic storm season to collect data on ocean conditions, which will help improve scientists’ understanding of hurricanes and pave the way for future improvements in hurricane intensity forecasts.  

“When storms are moving along our coasts, lives depend on accurate forecasts,” said Zdenka Willis, U.S. IOOS program director. “The unmanned gliders will allow us to collect data even in the middle of the storm and eventually provide this information to NOAA’s National Weather Service to help improve forecast precision so decision makers can keep people safe.”

Scientists will deploy the first gliders in the fleet in early September and continue deploying from different locations throughout the next two to three weeks. Each glider will be deployed for three to eight weeks, collecting data into October.

The underwater gliders can travel thousands of miles and continuously collect and send back ocean data. They can operate for several months at a time and can dive repeatedly to collect three-dimensional ocean observations.

Rutgers University is leading this combined science mission involving all three of the east coast IOOS regions: Northeast, Mid-Atlantic and Southeast. In addition to glider data, the mission will use satellite, moored buoy and coastal radar data. During the mission, the gliders will also collect acoustic data about fish and mammal migrations to improve the understanding of their behaviors.  

Collected glider data will go through NOAA’s National Data Buoy Center to NOAA’s National Weather Service, the U.S. Navy and other data users for modeling. Data from the glider missions will also be public and available on the IOOS Glider Asset Map and at http://www.ndbc.noaa.gov/gliders.php

In addition to NOAA funding, provided through the IOOS regions, other funding sources for the project include the Office of Naval Research, the Environmental Protection Agency, NASA, a private donor from the University of Delaware, and Canada’s Ocean Technology Network.

IOOS is a federal, regional and private sector partnership working to enhance the ability to collect, deliver and use ocean information. IOOS delivers the data and information needed to increase understanding of our ocean and coasts so that decision makers can act to improve safety, enhance the economy, and protect the environment.

Sanctuaries establishes new business advisory council

September 12, 2013

NOAA’s Office of National Marine Sanctuaries has established a new business advisory council to give its director the views of industry leaders as they work with corporate partners in marine resource protection.

“The ocean is a fundamental part of the U.S. economy, security, history, and culture,” said Daniel J. Basta, director of the Office of National Marine Sanctuaries.“However, the relationship between the conservation and commercial sectors is not well understood or coordinated. We hope this council will help us bridge that divide.”

Business leaders will be invited to join the council, which will consist of 15 volunteers representing industries such as travel and tourism, recreation, fishing, transportation, energy, and marketing. Members will be appointed by the national marine sanctuaries director and serve two- to three-year terms.

Council members will serve as liaisons between their industries and NOAA, keeping sanctuary leadership informed of issues and concerns, as well as providing information to their respective sectors about national marine sanctuary system initiatives. The council will not have a role in providing advice on regulatory or administrative matters.

The council will work with sanctuary leadership on strategies to use the sanctuary system’s recreational value and beauty to aid local economies, engage the corporate sector and other non-traditional partners in marine resource protection, and develop projects to sustain and protect the sanctuaries and other marine protected areas, among other initiatives.

For additional information about the business council, visit http://sanctuaries.noaa.gov/management/bac/

NOAA’s Office of National Marine Sanctuaries serves as trustee for a system of 14 marine protected areas, encompassing more than 170,000 square miles of America’s ocean and Great Lakes waters. Through active research, management, and public engagement, national marine sanctuaries sustain healthy environments that are the foundation for thriving communities and stable economies. Authority for the business advisory council is provided under the National Marine Sanctuaries Act.

U.S. 2012 Billion Dollar Weather and Climate Disasters. Full-size version also available.

According to NCDC’s 2012 weather and climate disasters information, 2012 saw 11 weather and climate disaster events each with losses exceeding $1 billion in damages. This makes 2012 the second costliest year since 1980, with a total of more than $110 billion in damages throughout the year. The 2012 total damages rank only behind 2005, which incurred $160 billion in damages due in part to four devastating land-falling hurricanes.

The 2012 billion-dollar events included seven severe weather and tornado events, two tropical cyclone events, and the yearlong drought and its associated wildfires. These 11 events killed over 300 people and had devastating economic effects on the areas impacted. With 11 events, 2012 also ranks second highest in total number of billion-dollar events behind 2011, which had 14 events.

The two major drivers of the damage costs in 2012 were Sandy at approximately $65 billion and the yearlong drought at approximately $30 billion. Sandy’s large size, with tropical storm force winds extending nearly 500 miles from the center, led to record storm surge, large-scale flooding, wind damage, and mass power outages along much of the East Coast.

The yearlong drought, which affected more than half the country for the majority of 2012, was the largest drought extent in the United States since the 1930s. U.S. Department of Agriculture Drought Disaster Declarations reached more than 2,600 of the Nation’s 3,143 counties. While drought impacts are often most costly to agricultural centers, their conditions also led to several devastating wildfires that burned over 9 million acres nationwide during 2012.

See NCDC’s Billion-Dollar Weather/Climate Disasters report for more information on the weather and climate events that have had the greatest economic impacts from 1980 to 2012.

Proposal extends rule reducing risk of whale ship strikes along U.S. East Coast

June 5, 2013

NOAA Fisheries Service is seeking comments on its proposal to make permanent the rules it implemented five years ago to reduce the number of collisions between ships and North Atlantic right whales.

Right whales are among the most endangered species in the world, and are highly vulnerable to ship collisions. The rules, part of NOAA’s long-standing efforts to recover right whales, are currently scheduled to expire in December 2013. NOAA’s proposal to make them permanent, which includes a 60-day public comment period, was filed at the Federal Register today.

The existing rules, which reduce an ocean-going vessel’s speed to 10 knots or less during certain times and locations along the East Coast from Maine to Florida, have reduced the number of whales struck by ships since 2008, when the speed limits began. No right whale ship strike deaths have occurred in Seasonal Management Areas since the rule went into place. Modeling studies indicate the measures have reduced the probability of fatal ship strikes of right whales by 80 to 90 percent.

NOAA biologists believe there are approximately 450 right whales in the NW Atlantic population. The whales face a number of challenges, including ship strikes and entanglement in fishing gear.

Also, NOAA’s revised estimates indicate that the restrictions cost the shipping industry and other maritime communities about one-third of original 2008 projections. NOAA scientists say that industry participation and compliance is high, and that in most cases vessels have incorporated speed restrictions into their standard operations and voyage planning.

"Reducing ship speeds in areas where there are endangered right whales works,” said NOAA Fisheries’ acting administrator Sam Rauch. “It is a proven method to reduce deaths and serious injury to these incredible creatures. Making these protections permanent will make U.S. East Coast waters safer for right whales, and will allow them to reach full maturity, which is critical to their long-term survival.”

North Atlantic right whales are among the most endangered species in the world. Historically depleted by commercial whaling, they suffers injury and death from ship strikes and entanglement in fishing gear.

The rule proposes to continue existing speed restrictions during migration periods along three regions of the U.S. East Coast (Northeast, Mid-Atlantic, and Southeast). These measures are implemented during the time of year when right whales occur in each area. Speed restrictions apply to vessels that are 65 feet in length or greater, except federal agency vessels.

The proposed rule also seeks public input on ways to measure the effectiveness of the existing speed restrictions and whether they should be phased out in the future.

This proposed rule is part of a more comprehensive approach to conserve right whales, including consulting on operations of federal ships under the Endangered Species Act, developing an expanded outreach and education program, and modifying shipping routes in waters of Massachusetts, Georgia and Florida. NOAA has also developed a dynamic management program whereby vessel operators are asked to travel less than 10 knots or avoid areas where whales occur in times and places not covered by seasonal speed restriction zones. Scientists expect these actions to significantly reduce the risks to right whales from ships.

The North Atlantic right whale primarily occurs in coastal or shelf waters. Its known range includes winter calving and nursery areas in coastal waters off the southeastern United States, and summer feeding grounds in New England waters and north to the Bay of Fundy and Scotian Shelf.

Historically depleted by commercial whaling, the North Atlantic right whale suffers injury and death from ship strikes and entanglement in fishing gear. These events may continue to contribute to the species decline and inability to recover. Biologists believe that there are approximately 450 right whales in the Northwest Atlantic population, and that the number is growing steadily.

The Endangered Species Act of 1973 requires recovery plans to serve as guides to promote the conservation and recovery of listed species. In 2005, NOAA Fisheries released a revised North Atlantic Right Whale Recovery Plan that provides an overall framework for promoting recovery of the whale. Measures to reduce risks posed by entanglement in fishing gear are contained in NOAA Fisheries’ Atlantic Large Whale Take Reduction Plan.

Written comments on the proposed regulations filed today must be sent to NOAA Fisheries no later than August 6.

After publishing a proposed rule, NOAA’s Fisheries Service considers the public comments and new information that may have been provided.

You may submit public comments via the Federal eRulemaking Portal at www.regulations.gov or by visiting the comment page on the Office of Protected Resources website at www.nmfs.noaa.gov/pr/comment.htm. NOAA’s Fisheries Service will also accept written comments mailed to: Office of Protected Resources, NOAA Fisheries, 1315 East-West Highway, Silver Spring, MD 20910; or faxed to 301-713-4060.

New analyses find evidence of human-caused climate change in half of the 12 extreme weather and climate events analyzed from 2012

September 5, 2013

The "Explaining Extreme Events of 2012 from a Climate Perspective" report was published today by the Bulletin of the American Meteorological Society. (Full report).

Human influences are having an impact on some extreme weather and climate events, according to the report “Explaining Extreme Events of 2012 from a Climate Perspective” released today by the Bulletin of the American Meteorological Society. Overall, 18 different research teams from around the world contributed to the peer-reviewed report that examined the causes of 12 extreme events that occurred on five continents and in the Arctic during 2012. Scientists from NOAA served as three of the four lead editors on the report.
The report shows that the effects of natural weather and climate fluctuations played a key role in the intensity and evolution of the 2012 extreme events. However, in some events, the analyses revealed compelling evidence that human-caused climate change, through the emission of heat-trapping gases, also contributed to the extreme event.

“This report adds to a growing ability of climate science to untangle the complexities of understanding natural and human-induced factors contributing to specific extreme weather and climate events,” said Thomas R. Karl, L.H.D, director of NOAA’s National Climatic Data Center (NCDC). “Nonetheless, determining the causes of extreme events remains challenging.”

In addition to investigating the causes of these extreme events, the multiple analyses of four of the events — the warm temperatures in the United States, the record-low levels of Arctic sea ice, and the heavy rain in both northern Europe and eastern Australia — allowed the scientists to compare and contrast the strengths and weaknesses of their various methods of analysis. Despite their different strategies, there was considerable agreement between the assessments of the same events.

Thomas Peterson, Ph.D., principal scientist at NOAA’s NCDC and one of the lead editors on the report, said, “Scientists around the world assessed a wide variety of potential contributing factors to these major extreme events that, in many cases, had large impacts on society. Understanding the range of influences on extreme events helps us to better understand how and why extremes are changing."

Key findings include:

Human-induced climate change had little impact on the lack of precipitation in the central United States in 2012.The 2012 spring and summer heat waves in the U.S. can be mainly explained by natural atmospheric dynamics, however, human-induced climate change was found to be a factor in the magnitude of warmth and was found to have affected the likelihood of such heat waves.  For example: High temperatures, such as those experienced in the U.S. in 2012 are now likely to occur four times as frequently due to human-induced climate change.Approximately 35 percent of the extreme warmth experienced in the eastern U.S. between March and May 2012 can be attributed to human-induced climate change.  

Hurricane Sandy Inundation Probability:

The record-setting impacts of Sandy were largely attributable to the massive storm surge and resulting inundation from the onshore-directed storm path coincident with high tide. However, climate-change related increases in sea level have nearly doubled today’s annual probability of a Sandy-level flood recurrence as compared to 1950. Ongoing natural and human-induced forcing of sea level ensures that Sandy-level inundation events will occur more frequently in the future from storms with less intensity and lower storm surge than Sandy. 

Arctic Sea Ice:

The extremely low Arctic sea ice extent in summer 2012 resulted primarily from the melting of younger, thin ice from a warmed atmosphere and ocean. This event cannot be explained by natural variability alone. Summer Arctic sea ice extent will continue to decrease in the future, and is expected to be largely absent by mid-century.  

Global Rainfall Events:

The unusually high amount of summer rainfall in the United Kingdom in 2012 was largely the result of natural variability. However, there is evidence that rainfall totals are influenced by increases in sea surface temperature and atmospheric moisture which may be linked to human influences on climate.The magnitude of the extreme rainfall experienced over southeastern Australia between October 2011 and March 2012 was mainly associated with La Niña conditions. However, the likelihood of above-average precipitation during March was found to have increased by 5 percent to 15 percent because of human influences on the climate. Extreme rainfall events such as the December 2011 two-day rainfall in Golden Bay, New Zealand, are more likely to occur due to a 1 percent to 5 percent increase in available moisture resulting from increased levels of greenhouse gases in the atmosphere.The July 2012 extreme rainfall events in North China and southwestern Japan were mainly due to natural variability.

NOAA confirms wreck is lost 19th century U.S. Coast Survey steamer

More than 153 years after it was lost in a violent collision at sea, government and university maritime archaeologists have identified the wreck of the ship Robert J. Walker, a steamer that served in the U.S. Coast Survey, a predecessor agency of NOAA.

The Walker, while now largely forgotten, served a vital role as a survey ship, charting the Gulf Coast ? including Mobile Bay and the Florida Keys ? in the decade before the Civil War. It also conducted early work plotting the movement of the Gulf Stream along the Atlantic Coast.

Twenty sailors died when the Walker sank in rough seas in the early morning hours of June 21, 1860, ten miles off Absecon Inlet on the New Jersey coast. The crew had finished its latest surveys in the Gulf of Mexico and was sailing to New York when the Walker was hit by a commercial schooner off New Jersey. The side-wheel steamer, carrying 66 crewmembers, sank within 30 minutes. The sinking was the largest single loss of life in the history of the Coast Survey and its successor agency, NOAA.

“Before this identification was made, the wreck was just an anonymous symbol on navigation charts,” said Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “Now, we can truly honor the 20 members of the crew and their final resting place. It will mark a profound sacrifice by the men who served during a remarkable time in our history.”

Built in 1847, the Walker was one of the U.S. government’s first iron-hulled steamers, and was intended for the U.S. Revenue Service, the predecessor of the United States Coast Guard. Instead, the Walker and some of its sister steamers were sent to the U.S. Coast Survey.
Admiral Robert J. Papp, commandant of the Coast Guard, said that Walker represented the transition from sail to steam for government vessels, “reflecting the enduring need of the United States to harness the power of new technology to promote its maritime interests.”

“Coast Guardsmen are always saddened by the loss of life at sea and especially so when those lost were working to make the lives of other mariners safer by charting the waters of the United States,” Papp said.

Observations from NOAA's Maritime Heritage program's diving team confirmed the identity of the Walker wreck.

The U.S. Coast Survey is NOAA’s oldest predecessor organization, established by President Thomas Jefferson in 1807 to survey the coast and produce the nation’s nautical charts. In 1860, as the Civil War approached, the Coast Survey redoubled efforts to produce surveys of harbors strategically important to the war effort along the Gulf and Atlantic coasts.

The New York Herald, in reporting the Walker’s loss on June 23, 1860, noted that a “heavy sea was running, and many of the men were doubtless washed off the spars and drowned from the mere exhaustion of holding on, while others were killed or stunned on rising to the surface by concussion with spars and other parts of the wreck.”

NOAA is able to confirm the identity of the Walker using various criteria, including the ship's unique paddlewheel flanges.

The Walker wreck site initially was discovered in the 1970s by a commercial fisherman. The wreck's identity has been a mystery despite being regularly explored by divers. Resting 85 feet underwater, the vessel’s identity was confirmed in June as part of a private-public collaboration that included research provided by New Jersey wreck divers; Joyce Steinmetz, a maritime archaeology student at East Carolina University; and retired NOAA Corps Capt. Albert Theberge, chief of reference for the NOAA Central Library.

While in the area to conduct hydrographic surveys after Hurricane Sandy for navigation safety, NOAA Ship Thomas Jefferson sailed to the wreck site and deployed its multibeam and sidescan sonar systems. Hydrographers searched likely locations based on analysis of historical research by Vitad Pradith, a physical scientist with NOAA’s Office of Coast Survey.

A NOAA Maritime Heritage diving team, on a separate Hurricane Sandy-related mission in the area, was able to positively identify the Walker. Key clues were the size and layout of the iron-hulled wreck, and its unique engines, rectangular portholes, and the location of the ship, which was found still pointing toward the Absecon lighthouse, the final destination of a desperate crew on a sinking vessel.

“The identification of Walker is a result of excellent collaboration with the local community,” said James P. Delgado, director of maritime heritage for NOAA’s Office of National Marine Sanctuaries. “We look forward to working with our local partners to share Walker’s story with the public in a manner that both promotes educational dive tourism and protects this nationally significant wreck and gravesite.”

NOAA’s intent is not to make the wreck a sanctuary or limit diving, but to work with New Jersey’s wreck diving community to better understand the wreck and the stories it can tell.

After a ceremony last month onboard NOAA Ship Thomas Jefferson, Ensign Eileen Pye lays a wreath over the waters where USCS Robert J. Walker sank.

“We want to enhance the dive experience and support the dive industry with enhanced access to this wreck,” Delgado said. “New Jersey is home to some of the most accomplished wreck divers who not only understand history and wrecks, but who have also been in the forefront of wreck exploration. We look forward to working with them on the Walker.”

Report highlights climate change threats to nation’s estuaries

August 7, 2013

Report on Climate Sensitivity of the National Estuarine Research Reserve System.

Full report. (Credit: NOAA)

The nation’s 28 National Estuarine Research Reserves (NERR) are experiencing the negative effects of human and climate-related stressors according to a new NOAA research report from the National Ocean Service. 

The national study, Climate Sensitivity of the National Estuarine Research Reserve System, points to three East Coast reserves, Sapelo Island NERR in Georgia, ACE Basin NERR in South Carolina and Waquoit Bay NERR in Massachusetts, and  the Tijuana River NERR on the California-Mexico border, as the most sensitive to climate change.

“The National Estuarine Research Reserves are uniquely positioned across the U.S. to assess ongoing climate change in our nation’s estuaries which is the degree to which the natural resources and the local communities who depend on them are affected by changing climate conditions,” said Dwight Trueblood, Ph.D. a co-author and NOAA program manager for the study. “This information is important to helping coastal managers and local community leaders make informed decisions about the best ways for coastal communities to adapt to climate change.”

Estuaries are places where rivers meet the sea, providing nursery habitat for fish and shellfish while buffering many coastal communities from the impacts of coastal storms and sea level rise. The climate exposure of each reserve provides first alarm indicators about the effects of climate change on the coastal ecosystems. Ongoing research at each of the reserves provides real-time data about how climate change impacts these important natural resources.

Almost 40 percent of all Americans, or about 123 million people, live in the counties directly along the shoreline and depend on these resources for food, jobs, storm protection, and recreation. Approximately 50 percent, or $6.6 trillion, of the nation’s gross domestic product comes from coastal watershed counties which support more than 51 million jobs.

Researchers determined the extent of relative climate sensitivity in the reserves by looking at five factors: social, biophysical, and ecological sensitivity, and exposure to temperature change and sea level rise.

Key Findings

Reserve ecological resilience was examined and the key underlying estuarine stressors were found to be toxic pollutants, storm impacts, invasive species, habitat fragmentation, sedimentation and shoreline erosion. The most frequently identified factors contributing to these stressors included residential development, land use, population growth, wastewater treatment and sea level rise.

High social sensitivity to climate change was indicated where there is higher employment within natural resource-dependent industries, lower per capita income and median home values, higher percentages of minority populations, and a higher percentage of individuals lacking a high school education.

Social sensitivity to climate change was generally highest in the southern portions of the East and West coasts of the U.S., the Gulf of Mexico and Alaska.

Biophysical sensitivity summarizes each reserve’s relationship between annual spring atmospheric temperature and rainfall data and water quality factors such as water temperature, dissolved oxygen and pH.

Temperature change exposure risk was greatest for reserves located in the Great Lakes, Gulf of Mexico, Mid-Atlantic, and Northeast regions of the country, while reserves in the Gulf of Mexico, parts of the Mid-Atlantic, Southeast, California, and Oregon showed the greatest risk of sea level rise exposure.

The study, funded by NOAA’s Climate Program Office, was conducted by a collaborative, interdisciplinary team of investigators from the University of Wisconsin, NOAA’s National Centers for Coastal Ocean Science, and Office of Ocean and Coastal Resource Management working with staff across the National Estuarine Research Reserve System.  For a digital copy of the full study is available online.

The National Estuarine Research Reserve System is a network of 28 reserves that serve as “living laboratories” around the U.S. representing unique biogeographically diverse coastal ecosystems. Established under the Coastal Zone Management Act, the reserves are jointly managed by NOAA and the coastal states and territories for long-term research, ecosystems monitoring, education, and coastal stewardship. Through integrated research and education, the reserves help communities develop strategies to deal successfully with coastal resource management issues such as water pollution, habitat restoration and climate change.

2012 was one of the 10 warmest years on record globally

August 6, 2013

The 2012 State of the Climate report is available online.

Worldwide, 2012 was among the 10 warmest years on record according to the 2012 State of the Climate report released online today by the American Meteorological Society (AMS). The peer-reviewed report, with scientists from NOAA’s National Climatic Data Center in Asheville, N.C., serving as lead editors, was compiled by 384 scientists from 52 countries (highlights, full report). It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments on land, sea, ice, and sky. 

“Many of the events that made 2012 such an interesting year are part of the long-term trends we see in a changing and varying climate — carbon levels are climbing, sea levels are rising, Arctic sea ice is melting, and our planet as a whole is becoming a warmer place," said Acting NOAA Administrator Kathryn D. Sullivan, Ph.D. “This annual report is well-researched, well-respected, and well-used; it is a superb example of the timely, actionable climate information that people need from NOAA to help prepare for extremes in our ever-changing environment."

Conditions in the Arctic were a major story of 2012, with the region experiencing unprecedented change and breaking several records. Sea ice shrank to its smallest “summer minimum” extent since satellite records began 34 years ago. In addition, more than 97 percent of the Greenland ice sheet showed some form of melt during the summer, four times greater than the 1981–2010 average melt extent.

The report used dozens of climate indicators to track and identify changes and overall trends to the global climate system. These indicators include greenhouse gas concentrations, temperature of the lower and upper atmosphere, cloud cover, sea surface temperature, sea-level rise, ocean salinity, sea ice extent and snow cover. Each indicator includes thousands of measurements from multiple independent datasets.

Highlights:

Warm temperature trends continue near Earth’s surface: Four major independent datasets show 2012 was among the 10 warmest years on record, ranking either 8th or 9th, depending upon the dataset used. The United States and Argentina had their warmest year on record. La Niña dissipates into neutral conditions:  A weak La Niña dissipated during spring 2012 and, for the first time in several years, neither El Niño nor La Niña, which can dominate regional weather and climate conditions around the globe, prevailed for the majority of the year.  The Arctic continues to warm; sea ice extent reaches record low: The Arctic continued to warm at about twice the rate compared with lower latitudes. Minimum Arctic sea ice extent in September and Northern Hemisphere snow cover extent in June each reached new record lows. Arctic sea ice minimum extent (1.32 million square miles, September 16) was the lowest of the satellite era. This is 18 percent lower than the previous record low extent of 1.61 million square miles that occurred in 2007 and 54 percent lower than the record high minimum ice extent of 2.90 million square miles that occurred in 1980. The temperature of permafrost, or permanently frozen land, reached record-high values in northernmost Alaska. A new melt extent record occurred July 11–12 on the Greenland ice sheet when 97 percent of the ice sheet showed some form of melt, four times greater than the average melt this time of year. Antarctica sea ice extent reaches record high: The Antarctic maximum sea ice extent reached a record high of 7.51 million square miles on September 26. This is 0.5 percent higher than the previous record high extent of 7.47 million square miles that occurred in 2006 and seven percent higher than the record low maximum sea ice extent of 6.96 million square miles that occurred in 1986. Sea surface temperatures increase: Four independent datasets indicate that the globally averaged sea surface temperature for 2012 was among the 11 warmest on record.  After a 30-year period from 1970 to 1999 of rising global sea surface temperatures, the period 2000–2012 exhibited little trend. Part of this difference is linked to the prevalence of La Niña-like conditions during the 21st century, which typically lead to lower global sea surface temperatures. Ocean heat content remains near record levels: Heat content in the upper 2,300 feet, or a little less than one-half mile, of the ocean remained near record high levels in 2012. Overall increases from 2011 to 2012 occurred between depths of 2,300 to 6,600 feet and even in the deep ocean. Sea level reaches record high: Following sharp decreases in global sea level in the first half of 2011 that were linked to the effects of La Niña, sea levels rebounded to reach record highs in 2012. Globally, sea level has been increasing at an average rate of 3.2 ± 0.4 mm per year over the past two decades.

Sea ice concentration reached a new record low in mid-September 2012. Credit: NOAA Climate.gov, based on NSIDC data. See more. 

Ocean salinity trends continue: Continuing a trend that began in 2004, oceans were saltier than average in areas of high evaporation, including the central tropical North Pacific, and fresher than average in areas of high precipitation, including the north central Indian Ocean, suggesting that precipitation is increasing in already rainy areas and evaporation is intensifying in drier locations. Tropical cyclones near average: Global tropical cyclone activity during 2012 was near average, with a total of 84 storms, compared with the 1981–2010 average of 89. Similar to 2010 and 2011, the North Atlantic was the only hurricane basin that experienced above-normal activity. Greenhouse gases climb: Major greenhouse gas concentrations, including carbon dioxide, methane, and nitrous oxide, continued to rise during 2012. Following a slight decline in manmade emissions associated with the global economic downturn, global CO2 emissions from fossil fuel combustion and cement production reached a record high in 2011 of 9.5 ± 0.5 petagrams (1,000,000,000,000,000 grams) of carbon , and a new record of 9.7 ± 0.5 petagrams of carbon  is estimated for 2012. Atmospheric CO2 concentrations increased by 2.1 ppm in 2012, reaching a global average of 392.6 ppm for the year. In spring 2012, for the first time, the atmospheric CO2concentration exceeded 400 ppm at several Arctic observational sites. Cool temperature trends continue in Earth’s lower stratosphere: The average lower stratospheric temperature, about six to ten miles above the Earth’s surface, for 2012 was record to near-record cold, depending on the dataset. Increasing greenhouse gases and decline of stratospheric ozone tend to cool the stratosphere while warming the planet near-surface layers.

The 2012 State of the Climate report is peer-reviewed and published annually as a special supplement to the Bulletin of the American Meteorological Society. This year marks the 23rd edition of the report, which is part of the suite of climate services NOAA provides to government, the business sector, academia, and the public to support informed decision-making. The full report can be viewed online.

Ocean explorers in July on NOAA Ship Okeanos Explorer discovered a wide diversity of seafloor features and communities of life in the largely unexplored deep-sea canyons off the northeast U.S. coast. Now through August 16, as the expedition continues, the public can join the mission as “citizen scientists,” at oceanexplorer.noaa.gov/okeanos, to see live seafloor video and listen as scientists discuss their observations in real time. During the expedition’s July leg, there were nearly 60,000 visits to the live streaming video.

Canyons represent some of the most striking features of the continental slope off the U.S. East Coast and may also be among the most productive areas in the deep sea. Organic matter and nutrient-rich sediments are often concentrated in these areas and strong currents flow through the steep and rugged terrain of the canyons, exposing hard substrates. With an increase in food availability and a variety of different habitat types across varying depths, submarine canyons may contain higher biodiversity and biomass than the adjacent continental slope, and are likely places to observe deep-sea corals, sponges, and other deep-sea marine organisms.

Close-up of methane hydrate observed at a depth of 1,055 meters, near where bubble plumes were detected in previous sonar data. Pressure and cold temperatures create methane hydrate where molecules of natural gas are trapped in an ice-like cage of water molecules. Methane hydrates, a hydrate patch and chemosynthetic communities were seen during this dive, but no active seepage was observed. Seeps were investigated at other locations.

During the July leg of the expedition, the ship’s multibeam sonar detected bubbles rising from the seafloor in several locations about 90 nautical miles southeast of Nantucket, Mass. These water-column plumes were traced to seafloor seeps where explorers observed chemosynthetic communities of life supported by chemicals rather than by sunlight. These are the northernmost seeps detected to date on the U.S. Atlantic margin.

The discoveries are expected to help fisheries and other ocean resource managers make better-informed decisions about how to manage, use and protect the ocean and its resources. Scientists believe the need to learn more about these relatively undisturbed canyon ecosystems is becoming more urgent, particularly as the potential for fishing, marine mining, and hydrocarbon exploration extends into the deep sea.

“We found these little-explored canyons are highly dynamic,” said Tim Shank, a deep-sea biologist from Woods Hole Oceanographic Institution, who participated from ashore. “With each dive of the ROVs (remotely operated vehicles that are undersea robots with cameras), we documented vertical walls with jagged rock failures, collapsed features, and extensive debris fields. Each canyon also appeared to host different biological communities — even different depths within the same canyon would reveal different types of coral and sponge ecosystems.

“As we explored different sides and depth zones of these canyons, we discovered a broad physical and biological diversity,” said Shank. “One canyon would host great animal diversity but low animal abundance and the next canyon would reveal just the opposite. As with any new deep-sea region we explore, we observed many suspected new species and remarkable range extensions of known species. All these observations will be highly informative to design and implement ocean conservation and management strategies in the near future.”

Explorers also observed several instances of new coral life establishing itself, hundreds of skate and cat shark eggs on the seafloor and attached to deep-sea corals, and numerous octopus and squid guarding clutches of eggs. Initial impressions revealed these canyons are hot spots for biodiversity, hosting more than 25 species of corals, and hundreds of associated animals.

Andrea Quattrini, a Ph.D. student from Temple University in Philadelphia, said the expedition provided an immense opportunity for the ocean science and management communities to educate and train the next generation of explorers and deep-sea scientists.

“Their ability to interact with thirty to forty scientists with different areas of expertise, and the free exchange of ideas and discussion, further advanced the exploration and findings by defining new questions and outlining exciting avenues for future research,” she said.

Teachers may take advantage of an Expedition Educational Module at http://go.usa.gov/jn2h. The site provides products tied to the expedition including standards-based lesson plans and ocean-career connections.

Brendan Roark, a geographer from Texas A&M University who participated in the expedition from the ship, believes corals in the area may live as long as 4,000 years. “Deep-sea corals provide a new archive that can help us reconstruct past ocean and climate conditions,” he said. “They grow in a shrub-like fashion and most importantly, they deposit annual growth rings much like trees do. Because of their extremely long life spans, they may develop high resolution records of oceanographic and climate variability.”

An international team of more than 40 scientists and students – partners from multiple federal agencies and academic institutions – located mostly on shore, participated in the expedition’s first leg, receiving data and live video from the ship via telepresence-technology, using satellite and Internet pathways. The science team included several scientists at sea and others in Washington D.C., 12 U.S. states and two nations.

Scientists on the expedition’s July leg mapped 7,209 square kilometers of seafloor as they explored areas between 560 meters (1,837 feet) and 2,135 meters (7,005 feet) deep, in and between Block, Alvin, Atlantis, Veatch and Hydrographer canyons. The second leg is exploring Welker, Oceanographer, Lydonia, Nygren and Heezen canyons as well as Mytilus Seamount, one of the easternmost seamounts along the submerged northeast New England Seamount Chain within the U.S. Exclusive Economic Zone. Very little information exists for these areas. Scientists on both expedition legs are obtaining valuable data using the latest technologies including state-of-the-art multibeam sonar and NOAA’s new 6,000-meter ROV, Deep Discoverer, coupled with the Seirios camera sled and lighting platform.

NOAA Fisheries’ Deep-Sea Coral Research and Technology Program and the Northeast Regional planning team contributed scientific and financial support to this expedition. The program provides scientific information needed by NOAA and regional management councils to conserve and manage the nation’s deep-sea coral ecosystems.

Application to import 18 beluga whales for public display denied

August 6, 2013

Following a number of public engagement efforts, NOAA Fisheries today announced it is denying the Georgia Aquarium’s request for a permit to import 18 beluga whales from Russia for public display in the United States. NOAA Fisheries based the decision on requirements of the Marine Mammal Protection Act (MMPA).

The MMPA allows marine mammals to be removed from the wild or imported for the purpose of public display, and provides a process for issuing permits. This is the first application for a permit to import recently caught wild marine mammals in more than 20 years.

“The Georgia Aquarium clearly worked hard to follow the required process and submit a thorough application, and we appreciate their patience and cooperation as we carefully considered this case,” said Sam Rauch, acting assistant NOAA administrator for NOAA Fisheries. “However, under the strict criteria of the law, we were unable to determine if the import of these belugas, combined with the active capture operation in Russia and other human activities, would have an adverse impact on this stock of wild beluga whales.”

After careful review, NOAA Fisheries concluded that the application did not meet several of the MMPA permit criteria. NOAA Fisheries denied the permit application because:

NOAA Fisheries is unable to determine whether or not the proposed importation, by itself or in combination with other activities, would have a significant adverse impact on the Sakhalin-Amur beluga whale stock, the population that these whales are taken from; NOAA Fisheries determined that the requested import will likely result in the taking of marine mammals beyond those authorized by the permit; NOAA Fisheries determined that five of the beluga whales proposed for import, estimated to be approximately 1½ years old at the time of capture, were potentially still nursing and not yet independent.

The Aquarium sought to import the whales from Utrish Marine Mammal Research Station on Russia’s Black Sea Coast for public display at its own facility in Atlanta and at partner facilities, including SeaWorld of Florida, SeaWorld of Texas, SeaWorld of California and Shedd Aquarium in Chicago.

The whales were captured from Russia’s Sea of Okhotsk between 2006 and 2011. There is little reliable scientific information about the size and population trend of the Sakhalin-Amur stock of belugas, and the impact on the stock of other human activities, such as hunting and fishing, is unknown.

NOAA Fisheries held a public hearing on the proposed beluga whale importation on October 12, 2012. The 60-day public comment period closed Oct. 29, 2012, with NOAA Fisheries receiving approximately 9,000 comments.

Beluga whales are social animals that typically migrate, hunt and interact together in groups of ten to several hundred in the arctic and subarctic waters of Russia, Greenland and North America. Beluga whales face a number of threats including ship strikes, pollution, habitat destruction and entanglement in fishing gear.

Atlantic hurricane season on track to be above-normal

NOAA issued its updated Atlantic hurricane season outlook today saying the season is shaping up to be above normal with the possibility that it could be very active. The season has already produced four named storms, with the peak of the season – mid-August through October – yet to come.
“Our confidence for an above-normal season is still high because the predicted atmospheric and oceanic conditions that are favorable for storm development have materialized,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center, a division of the National Weather Service. “Also, two of the four named storms to-date formed in the deep tropical Atlantic, which historically is an indicator of an active season.”
The conditions in place now are similar to those that have produced many active Atlantic hurricane seasons since 1995, and include above-average Atlantic sea surface temperatures and a stronger rainy season in West Africa, which produces wind patterns that help turn storm systems there into tropical storms and hurricanes.
The updated outlook calls for a 70 percent chance of an above-normal season. Across the Atlantic Basin for the entire season – June 1 to November 30 – NOAA’s updated seasonal outlook (which includes the activity to date of tropical storms Andrea, Barry, Chantal, and Dorian) projects a 70 percent chance for each of the following ranges:

13 to 19 named storms (top winds of 39 mph or higher), including 6 to 9 hurricanes (top winds of 74 mph or higher), of which3 to 5 could be major hurricanes (Category 3, 4 or 5; winds of at least 111 mph)

These ranges are above the 30-year seasonal averages of 12 named storms, six hurricanes and three major hurricanes.

The updated outlook is similar to the pre-season outlook issued in May, but with a reduced expectation for extreme levels of activity. Motivating this change is a decreased likelihood that La Niña will develop and bring its reduced wind shear that further strengthens the hurricane season. Other factors are the lack of hurricanes through July, more variability in the wind patterns across the tropical Atlantic Ocean and slightly lower hurricane season model predictions. In May, the outlook called for 13-20 named storms, 7-11 hurricanes and 3-6 major hurricanes.

“The peak of the hurricane season is almost upon us and it’s important to remain prepared for hurricanes through November," said Joe Nimmich, FEMA Associate Administrator for Response and Recovery. "Make sure to review your family emergency plan, check that your emergency kit is stocked and consider insurance options.

NOAA, EUMETSAT sign long-term agreement for weather, climate monitoring

August 28, 2013

Building on a 30-year relationship, top officials from NOAA and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) signed a long-term cooperative agreement, ensuring continued space-based weather, water and climate monitoring.

At a ceremony at the European Union (EU) Delegation in Washington, D.C. yesterday, Kathryn D. Sullivan, Ph.D., NOAA acting administrator and Alain Ratier, EUMETSAT’s director general, signed the agreement. They were joined by Dr. Francois Rivasseau, deputy chief of mission, EU Delegation to the United States.

“The need for environmental intelligence has never been stronger. This partnership with our EUMETSAT colleagues allows us to continue collecting and sharing vital space-based observations, resulting in a better understanding of our global environment,” Sullivan said.

Ratier added, “The partnership between EUMETSAT and NOAA has continuously developed over the last 30 years and taken a strategic dimension, bringing substantial benefits to Europe, the USA and the worldwide user communities. Today the partnership covers back-up arrangements and data exchange for geostationary satellites and full sharing of low Earth orbit satellite systems, with the Initial Joint Polar System and the Jason series. With this agreement, we have established a policy framework to further develop our cooperation into the next decades.”

Key successes of the NOAA-EUMETSAT partnership include:

NOAA and EUMETSAT operate a joint polar satellite system, where EUMETSAT’s Metop satellites fly in the mid-morning orbit, while NOAA’s polar satellites and the Suomi NPP spacecraft fly in the afternoon orbit. Both agencies share all the data, which form the backbone of all medium range weather forecasts in the United States and Europe and make up the majority of the data used by the U.S. weather model (GFS) and the major European weather model (ECMWF).NOAA instruments fly onboard the EUMETSAT satellites, and EUMETSAT instruments are on the NOAA spacecraft, providing cost savings and more uniform datasets for meteorologists and scientists across continents.NOAA and EUMETSAT also exchange data from geostationary satellites, and have a back-up agreement in place for data sharing should either agency’s spacecraft experience trouble.The partnership also extends to the Jason-2 ocean surface topography mission that has been crucial to improvements in weather modeling and tropical storm intensification forecasting, and is supporting the EU-led Copernicus Earth Observation program with data from the Suomi NPP satellite.

After 10 years of service, GOES-12 satellite retires

August 19, 2013

GOES-12 captured this visible image of Hurricane Katrina on August 28, 2005, at 11:45 a.m. (EDT). At that time, the storm was at Category 5 strength and projected to impact New Orleans.

GOES-12 has seen it all, from Hurricane Katrina that hit the Gulf Coast in 2005, to the Christmas blizzard that crippled the Central United States in 2009. It even traveled south of the equator to provide coverage for South America starting in 2010. Now, after more than 10 years of stellar service, NOAA’s Geostationary Operational Environmental Satellite (GOES)-12 spacecraft is being retired.

Launched on July 23, 2001, the satellite lasted well beyond its original operational design life of two years for on-orbit storage and five years of actual operations to support forecasters and scientists in NOAA’s National Weather Service.

“GOES-12 gave the Western Hemisphere many years of reliable data as the operational eastern GOES for accurate forecasts, from small storms to those of historic proportions,” said Mary Kicza, assistant administrator for NOAA’s Satellite and Information Service.

Built by Space Systems/Loral, GOES-12 became operational April 1, 2003 as the GOES-East satellite, monitoring weather across the U.S. East Coast and part of the Atlantic Ocean. On May 10, 2010, when GOES-12 was no longer able to be maintained to meet the requirements of the National Weather Service, it was shifted to a new position, where it provided coverage of weather conditions affecting South America, including volcanic ash clouds, wildfires, and drought.

When NOAA decommissions a geostationary satellite like GOES-12, it is boosted further into orbit, the remaining fuel is expended, the battery is disabled and the transmitters are turned off. These maneuvers reduce the chances the satellite will collide with other operational spacecraft. Additionally, decommissioning lowers the risk of orbital debris and stops the satellite from transmitting any signals that could interfere with any current or future spacecraft.

NOAA continues to operate GOES-13, which serves as the GOES East satellite for the United States and GOES-15, which is the GOES West satellite - both hovering 22,300 miles above the equator. NOAA also has an orbital backup geostationary satellite, GOES-14, which can be activated if any of the operational satellites experience trouble.

Kicza added: “The NOAA-NASA partnership is making steady progress toward developing and launching the more advanced GOES-R satellite series to position us into the future.”

GOES-R is expected to more than double the clarity of today’s GOES imagery and provide more atmospheric observations than current capabilities with more frequent images.

On January 29, 2010, GOES-12 captured a powerful storm developing in the U.S. mid-west. In the coming days, two blizzards hit the East Coast resulting in historic snowfall totals.

Data from the GOES-R instruments will be used to create many different products that will help NOAA meteorologists and other users monitor the atmosphere, land, ocean and the sun. GOES-R will also carry a new Geostationary Lightning Mapper that will provide for the first time a continuous surveillance of total lightning activity throughout the Americas and adjacent oceans.

In addition to GOES, NOAA also operates the polar operational environmental satellite (POES) program satellites, the Defense Meteorological Satellites Program series satellites and the Suomi NPP spacecraft.

National Weather Service more than doubles computing capacity

July 29, 2013

This is the Hurricane Weather Research and Forecasting (HWRF) model showing the Tropical Storm Flossie precipitation forecast for the Hawaiian Islands on July 29, 2013. HWRF is one of the sophisticated numerical computer models now being run on NOAA's new supercomputers.

Whizzing through 213 trillion calculations per second, newly upgraded supercomputers of NOAA’s National Weather Service are now more than twice as fast in processing sophisticated computer models to provide more accurate forecasts further out in time. And as the hurricane season ramps up, forecasters will be armed with an enhanced hurricane model that will improve track and intensity forecasts.

The scientific data and insights that these newly upgraded supercomputers will provide are essential to help government officials, communities, and businesses better understand and manage the risks associated with extreme weather and water events. In support of the president’s Climate Action Plan, the administration will continue to take steps like this to analyze and predict climate variability amid an increasing number of extreme natural events affecting the nation.

“These improvements are just the beginning and build on our previous success. They lay the foundation for further computing enhancements and more accurate forecast models that are within reach,” said Louis W. Uccellini, Ph.D., director of NOAA’s National Weather Service. “These upgrades are a game-changer for the entire public and private weather industry. In addition to the benefits to our own forecasters and products, we will provide our private sector partners with better information to empower them to enhance their services.”

Nicknamed “Tide,” the supercomputer in Reston, Va., and its Orlando-based backup named “Gyre,” are operating with 213 teraflops (TF) — up from the 90 TF with the computers that preceded them. This higher processing power allows the National Weather Service to implement an enhanced Hurricane Weather Research and Forecasting (HWRF) model.

"These forecasting advances can save lives,” said U.S. Sen. Bill Nelson, who helped get funding to add even more capacity to the supercomputer. “It's going to allow for better tracking of life-threatening storms and more accurately predict when and where they'll hit, and with what intensity."

With improved physics and a storm-tracking algorithm, the model has displayed up to a 15 percent improvement in both track and intensity forecasts, compared to last year's version of the model. The upgraded HWRF is also capable of processing real-time data collected from the inner core of a tropical system by the tail Doppler radar attached to NOAA’s P3 hurricane hunter aircraft, data which are expected to produce even greater forecast improvements.

“Next comes the quantum leap,” added Uccellini. Following this round of long-planned upgrades, funding requested in the FY 2014 President’s Budget, in addition to funding provided to NOAA by Congress in the spring of 2013 as part of the Hurricane Sandy emergency supplemental appropriations bill, would increase computing power even further to 1,950 TF by summer 2015. “That gives us the necessary computer power to run an enhanced version of our primary forecast model, the Global Forecast System,” said Uccellini.

"Given recent events like the tornado in Moore, Oklahoma or Superstorm Sandy, federal weather resources and personnel should be considered vital national assets. These upgrades assure world-class capabilities and a continued pathway to keep American lives and property safer," said J. Marshall Shepherd Ph.D., president of the American Meteorological Society and Professor at the University of Georgia. "As a father of two children and a scientist that understands looming weather threats, I take comfort in these developments."

Investments in supercomputing power for weather prediction are another step in NOAA’s efforts to build a Weather-Ready Nation. NOAA’s Weather-Ready Nation initiative, launched nearly two-years ago, has resulted in improvements in products, services and the way information is communicated to the public and partners. These improvements increase resilience to severe weather and reduce the potential of significant societal and economic impacts from severe weather.  A Weather-Ready Nation is a society that is prepared for, and responds effectively to, weather-related events.
