NOAA’s Office of Coast Survey, which creates and maintains the nation’s suite of over a thousand nautical charts of U.S. coastal waters, today announced major changes ahead for mariners and others who use nautical charts. Starting April 13, the federal government will no longer print traditional lithographic (paper) nautical charts, but will continue to provide other forms of nautical charts, including print on demand charts and versions for electronic charting systems.

“Like most other mariners, I grew up on NOAA lithographic charts and have used them for years,” said Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “We know that changing chart formats and availability will be a difficult change for some mariners who love their traditional paper charts, but we’re still going to provide other forms of our official charts.”

Since 1862, those lithographic nautical charts -- available in marine shops and other stores -- have been printed by the U.S. government and sold to the public by commercial vendors. The decision to stop production is based on several factors, including the declining demand for lithographic charts, the increasing use of digital and electronic charts, and federal budget realities.

“With the end of traditional paper charts, our primary concern continues to be making sure that boaters, fishing vessels, and commercial mariners have access to the most accurate, up-to-date nautical chart in a format that works well for them,” said Capt. Shep Smith, chief of Coast Survey’s Marine Chart Division. “Fortunately, advancements in computing and mobile technologies give us many more options than was possible years ago.”

NOAA will continue to create and maintain other forms of nautical charts, including the increasingly popular Print on Demand (POD) charts, updated paper charts available from NOAA-certified printers. NOAA electronic navigational charts (NOAA ENC®) and raster navigational charts (NOAA RNC®), used in a variety of electronic charting systems, are also updated weekly and are available for free download from the Coast Survey website. NOAA will also announce a new product full-scale PDF (Portable Digital Format) nautical charts, available for free download on a trial basis online.

Electronic charts, layered with multi-faceted information, are increasingly popular with commercial pilots around the world.

The world of navigation is benefiting from advances in technology, Smith explained. He said that NOAA will consult with chart users and private businesses about the future of U.S. navigation, especially exploring the use of NOAA charts as the basis for new products.

“Customers frequently ask us for special printed features, such as waterproof charts, special papers, or chart books containing additional information,” he said. “We are investigating new opportunities for companies to fill these market niches, using the most up-to-date information directly from NOAA.”

NOAA’s Office of Coast Survey is the nation’s nautical chartmaker. Originally formed by President Thomas Jefferson in 1807, Coast Survey updates charts, surveys the coastal seafloor, responds to maritime emergencies, and searches for underwater obstructions that pose a danger to navigation.

Grant helps protect critical Hudson River estuarine habitat

June 13, 2013

Stockport, NY.

NOAA's Coastal and Estuarine Land Conservation Program helped protect over 300 acres of critical lands along the Hudson River near the town of Stockport, NY that will be managed by the NYS Department of Environmental Conservation as a protected wildlife habitat, open to the public for passive recreational use.

A NOAA grant of more than $800,000 has helped New York state complete the acquisition of nearly 300 acres of critical habitat located within the Stockport Creek and Flats biologically important area.

New York’s departments of State and Environmental Conservation and the Scenic Hudson Land Trust, the largest environmental group focused on the Hudson River Valley, joined in the purchase.

The $806,017 grant comes from a fiscal year 2010 grant competition held by NOAA’s Coastal and Estuarine Land Conservation Program (CELCP).

The acquisition will conserve and permanently protect key spawning and nursery habitat for the Hudson River’s migratory fish including blueback herring, alewife, American shad, American eel, striped bass, and the federally endangered short-nosed sturgeon. In addition, 64 acres of globally rare freshwater tidal wetlands will be protected including a segment of land that is part of an important bald eagle habitat corridor.

“This important acquisition will protect vital intertidal marsh and swamp, floodplain forest, and buffer lands which are critical habitat for a host of birds, fish, and other fauna,”said Betsy Blair, manager of the Hudson River reserve. “It will also enable tidal wetlands to migrate landward and upslope with sea level rise, building resilience to climate change in the Hudson River estuary”

“This NOAA conservation grant program is one of America’s best investments because it leverages funds from federal, state and private partners to acquire and protect acres of critical coastal habitat that supports both coastal communities and its ecosystems,” said Margaret Davidson, acting director of NOAA’s Office of Ocean and Coastal Resource Management. “NOAA is pleased to have contributed to the preservation of this important area of the Hudson River valley.”

This acquisition will protect one of the last major privately owned holdings within the NOAA-funded Hudson River National Estuarine Research Reserve -- a parcel known as the Plotkin property, which will be owned by New York state’s department of environmental conservation (DEC) and managed as a protected wildlife habitat open to the public for passive recreational use.

With the addition of the Plotkin property, the reserve’s Nutten Hook State Unique Area to the north and Hudson River Islands State Park, Gays Point Section to the south, will now be linked to protect almost five miles of contiguous shoreline within the Stockport Flats component of the Hudson River NERR. The property straddles the towns of Stuyvesant and Stockport in Columbia County, N.Y.

“Protecting the ecological values of Little Nutten Hook and Stockport Flats is critical to maintaining and improving Hudson River habitats for numerous fisheries, migratory waterfowl and marsh birds,” said New York DEC Commissioner Joe Martens. “These habitats are important for both the species that depend on them as well as the numerous recreational and economic benefits the Hudson River provides to the people of New York State.”

The Hudson River reserve, one of 28 national estuarine research reserves, is a network of four sites along the Hudson River containing 5,000 acres of estuarine habitat designated in 1982 by NOAA and New York state. The reserve receives funding from NOAA, under the federal Coastal Zone Management Act, and is operated by the DEC as natural field laboratories for research and education, with a strong focus on conserving natural resources, biodiversity, and public access.

NOAA’s CELCP program, established by Congress in 2002 to advance the objectives of the Coastal Zone Management Act, has protected nearly 100,000 acres of critical coastal and estuarine lands in partnership with federal, state, territorial and local government agencies and private organizations.

Study finds fishing tops U.S. lightning death activities

June 24, 2013

NOAA's National Weather Service has discovered that 64 percent of lightning deaths since 2006 occurred while people were participating in leisure activities, with fishing topping the list at 26 deaths. John Jensenius, a lightning safety specialist with the National Weather Service, conducted the study by examining demographic information for 238 deaths attributed to lightning over the last seven years. NOAA released these findings on the first day of National Lightning Safety Awareness Week to call attention to the danger of outdoor activities during a thunderstorm.

Of the 152 deaths associated with leisure activities, fishing is followed by camping (15 deaths), boating (14 deaths), soccer (12 deaths) and golf (8 deaths). The remaining 77 people were struck by lightning while participating in a number of other leisure activities like enjoying the beach, swimming, walking and running, riding recreational vehicles, and picnicking or relaxing in their yard. Between 2006 and 2012, 82 percent of people killed by lightning were male.

“When people think of lightning deaths, they usually think of golf,” Jensenius said. “While every outdoor activity is dangerous when a thunderstorm is in the area, outdoor activities other than golf lead to more lightning deaths. NOAA has made a concerted effort to raise lightning awareness in the golf community since we began the campaign in 2001, and we believe our outreach has made a huge difference since lightning-related deaths on golf courses have decreased by 75 percent.”

Jensenius said the large number of fishing, camping and boating lightning deaths may occur because these activities require extra time to get to a safe place. “People often wait far too long to head to safety when a storm is approaching, and that puts them in a dangerous and potentially deadly situation,” he said.

Prior to the lightning safety campaign, lightning killed an average of 73 people each year in the United States. Since the National Weather Service launched the campaign, the average has dropped to 37. Seven people have died from lightning strikes so far this year.

The best way for people to protect themselves against lightning injury or death is to monitor the weather and postpone or cancel outdoor activities when thunderstorms are in the forecast. Lightning can strike from 10 miles away, so if people can hear thunder, they are in danger of being struck by lightning. The only safe places to be during a thunderstorm are in a building with four walls and a roof or in a car. A hut, cabana, tent, or other rain shelter will not protect a person from being struck by lightning.

National Weather Service forecast offices throughout the country will promote lightning safety at local events all week. Here are a few highlights:

Lightning Safety Awareness Week kicked off on Friday, June 21 in Parker, Colorado. NOAA experts joined partners from the Lightning Protection Institute, the Colorado Department of Homeland Security, local fire officials, other lightning safety partners and local TV meteorologist Jeff Womack for a public open house safety event at South Metro Fire Station #45. After hearing lightning safety education talks, visitors toured the fire station and spoke with lightning experts.On June 22, the Binghamton, NY, forecast office participated in the Moscow Country Run in Moscow, PA, by announcing the starting commands of the race. The run was a combination lightning safety event and fundraiser for Jason Penecek, who was struck by lightning while attending the Pocono 400 NASCAR race at Pocono Raceway last August. Jason, who lost his best friend of almost 20 years during the storm, continues to struggle with debilitating injuries. The run consisted of three events: The Lightning Bolt 5k, the One-Mile Shock Walk and the Kids Thunder Run. Jason’s experience as a lightning strike victim and journey back to health inspired his sister and fellow runner, Kimberly McHale, to create a local Lightning Awareness Group, which visits local schools and community events to promote lightning safety awareness.On June 28, the National Weather Service will team up with the Boston Red Sox at Fenway Park to promote lightning safety awareness at the major league baseball game. Meteorologists from the NWS Boston Forecast Office will host an information booth, and lightning safety information will appear on the video board during the 5th inning of the game against the Toronto Blue Jays. Yellow lightning safety foam visors will go to 300 young fans.

To ease impact of quota cuts on New England groundfisheries, NOAA proposes opening long-time closure areas

As part of an overall effort to help fishermen adjust to new quota cuts for groundfish implemented last month, today, NOAA Fisheries announced a proposal to open approximately 33 percent of areas currently closed to protect groundfish and habitat that have been off limits for nearly 20 years -- that is 2,925 square miles of the approximately 8,920 sq miles currently closed. The proposal also includes protections to ensure that habitat, vulnerable groundfish stocks, and other species, such as whales and harbor porpoise, are not put at risk.

In April, based largely on advice from the New England Fishery Management Council, NOAA Fisheries announced its final management measures for the Northeast groundfish fishery, including much lower quotas for some key stocks. Those measures went into effect in May. NOAA Fisheries has been working for months to lessen the effects of these cuts on fishermen and fishing communities, including increasing quotas and approving use of various gear and fishing methods to help fishermen better target healthy groundfish and other stocks prior to today’s announcement.

“We’ve been working with fishermen, state managers and others to find creative ways to help fishermen identify sustainable fishing opportunities this year,” said John Bullard, NOAA Fisheries northeast regional administrator. “Today’s action is another step in our overall effort to help transition fishing effort to healthy, more abundant fish stocks, while we work to rebuild cod and other stocks in poor condition and protect important habitats that are crucial for the overall health of our marine ecosystems.”

The three offshore areas under consideration lie to the south and east of Cape Cod. NOAA Fisheries does not propose to reopen these areas in their entirety; specific sections will remain closed based on the Council’s recommendations to protect habitat. Also, catch of stocks that are in poor condition, such as Georges Bank yellowtail and cod stocks, or are spawning, will be minimized through seasonal restrictions and the use of selective trawl and hook gear.

While these areas have been closed to groundfishing, other fishing activities have occurred in portions of these areas including lobster fishing. NOAA Fisheries also proposes to enact an agreement negotiated between groundfish and lobster fishermen, and recommended by the Atlantic States Marine Fisheries Commission, which limits groundfishing to times of year when lobster fishing is not as prevalent to minimize the potential for conflict between gear types.

“When year-round closures were put in place, our main goal was to reduce groundfish catch. However, now that fishermen are operating under annual catch limits, we no longer need year-round closures to control total catch but some areas still need to remain closed to protect habitat and those that we open must be opened in a responsible and sustainable way,” continued Bullard.

In areas that NOAA Fisheries is proposing to reopen, the agency is proposing to require monitoring on all fishing trips to gather data on fish caught and possible interactions with whales, harbor porpoise, and other animals. Fishing vessel operators wanting access to these areas will be required to cover the cost of monitoring.

NOAA Fisheries is also proposing to keep inshore year-round closures in place. This decision is due to the poor condition of Gulf of Maine cod and haddock and concerns expressed by a number of commercial and recreational fishermen and members of the environmental community.

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.

Joint Polar Satellite System completes critical program reviews

June 27, 2013

NOAA’s Joint Polar Satellite System (JPSS) recently completed two key programmatic reviews at NASA’s Goddard Space Flight Center, and is continuing a steady, on schedule and on budget march toward the 2017 launch of JPSS-1, the second in the series of next generation polar-orbiting weather satellites.

These detailed reviews, known as the Program System Definition Review (P/SDR) and JPSS-1 Mission Preliminary Design Review (MPDR), show the program is on track as it moves forward to meeting even higher-level critical milestones later this summer. The P/SDR is an independent review that evaluates the proposed structure of the program and finalizes the content, schedule and cost. The MPDR is a milestone for an independent review of the design of the JPSS-1 mission, including how the satellite, ground system, launch service, and operations all come together to achieve the mission objectives.

“Completing these reviews demonstrates the success and progress we are making within the overall JPSS program,” said Harry Cikanek, NOAA JPSS program director. “I am proud of the work our combined NOAA/NASA team has done to aggressively implement this program and deliver our products on budget and on schedule.”

Next on tap for the JPSS-1 mission, for which the instruments are almost complete and the spacecraft construction is well underway, is Key Decision Point-C, and the JPSS program Key Decision Point-I. These two additional reviews will monitor the overall readiness of JPSS, and are expected to occur this summer. Following this, the next milestone for the JPSS-1 mission is a Critical Design Review in early 2014. The next major review for the program overall will be in 2015.

The JPSS satellites are a follow on from the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite, a joint NOAA and NASA satellite and the first spacecraft in the JPSS series, launched on Oct. 28, 2011. Since its launch, the Suomi NPP spacecraft, instruments, and ground system have demonstrated successful operation, showcasing the JPSS capabilities to come.

The JPSS satellites represent significant technological and scientific advances for more accurate weather forecasting to improve prediction capabilities that save lives, facilitate the flow of commerce, and protect the economic interests of both the public and private sectors during severe weather events. NOAA, working in partnership with NASA, ensures a continuous flow of global data for monitoring and forecasting environmental phenomena.

NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources.

NOAA Corps Capt. Harris B. Halverson today assumed command of the NOAA Aircraft Operations Center in Tampa, Fla. The center is home to most of NOAA’s environmental research, reconnaissance and survey aircraft, including the agency’s “hurricane hunter” planes.

Halverson relieved Capt. Randall J. TeBeest, who had served as the center’s commanding officer since July 2011. The Aug. 2 change-of-command ceremony was presided over by Rear Adm. David A. Score, deputy director for operations for the NOAA Office of Marine and Aviation Operations.

“Capt. TeBeest’s service as the center’s commanding officer has been exemplary, and we thank him for his dedication and leadership,” said Score. “NOAA’s aircraft operations will also be well-served by Capt. Halverson, a proven leader who is committed to the safety and success of every mission NOAA flies on behalf of the nation.” Halverson was born in Minneapolis and was raised both in Minnesota and the Tampa Bay area. Upon graduation from Lakewood High School in St. Petersburg, Fla., in 1984, he enlisted in the U.S. Marine Corps, and was accepted into the Naval Academy Preparatory School. He attended the U.S. Naval Academy and graduated in 1990 with a degree in oceanography.

He later completed U.S. Navy flight training and was assigned to Patrol Squadron 16 in Jacksonville, Fla., where he flew P-3C Orion anti-submarine aircraft. He completed two six-month deployments as aircraft commander and as Chief of Naval Operations special project (Beartrap) mission commander. Halverson was nominated for Naval Aviator of the Year in 1997.
In 1998, Halverson transferred to Patrol Squadron 30, where he instructed newly designated naval aviators until he completed an inter-service transfer as a lieutenant commander to the NOAA Commissioned Officer Corps in 2000. Initially assigned to the center, he qualified as hurricane aircraft commander and received the NOAA Office of Marine and Aviation Operations Employee of the Year Award for 2003. Halverson also managed a project to install a tail Doppler radar system on NOAA’s Gulfstream IV-SP aircraft. He has piloted NOAA hurricane hunter aircraft into more than 30 tropical cyclones, including Hurricane Sandy.

In 2008, Halverson assumed the duties of executive officer of NOAA Research and was promoted in 2009 to the senior executive service position of acting director of NOAA’s Office of Ocean Exploration and Research. He returned to  the center in 2010 to serve as chief of its operations branch.

Halverson is a graduate of both the Naval Postgraduate School’s Aviation Safety Program and Harvard’s Senior Executive Fellows Program. He lives in Tampa with his wife and two children.

Located at MacDill Air Force Base in Tampa, the Aircraft Operations Center is part of the NOAA Office of Marine and Aviation Operations, which includes civilians and officers of the NOAA Corps, one of the nation’s seven uniformed services.

NOAA and its research partners predict that the 2013 western Lake Erie harmful algal bloom (HAB) season will have a significant bloom of cyanobacteria, a toxic blue-green algae, this summer. The predicted bloom is expected to be larger than last year, but considerably less than the record-setting 2011 bloom. Bloom impacts will vary across the lake’s western basin. This marks the second time NOAA has issued an annual outlook for western Lake Erie.

“This annual forecast and NOAA’s weekly bulletins provide the most advanced ecological information possible to Great Lakes businesses and resource managers so they can save time and money on the things they do that drive recreational activities and the economy,” said Holly Bamford, Ph.D., NOAA’s assistant administrator for the National Ocean Service.

Harmful algae blooms were common on western Lake Erie in the 1960s and 1970s. After a lapse of nearly 20 years, they have been steadily increasing over the past decade. As an early warning system, NOAA has issued weekly HABS bulletins for western Lake Erie since 2008 through the National Centers for Coastal Ocean Science (NCCOS). The weekly bulletins will continue in 2013.

“This information is critical for tourists, coastal businesses, water treatment plant operators, state and regional natural resource managers and scientists throughout Ohio, the region, and the country,” said Jeff Reutter, Ph.D., director of  Ohio State University’s Sea Grant program and Stone Laboratory. “In Ohio, as part of our Phosphorus Task Force II, we have used information from the NOAA model to help us target reductions in the amount of phosphorus going into the lake that would eliminate, or greatly reduce, the HABs.”

“The timing, size and location of blooms heavily impact our charter businesses,” said Captain Rick Unger, owner of Chief’s Charters and president of the Lake Erie Charter Boat Association. “I use the weekly bulletins to plan my trip routes and fuel costs, but more importantly they help me get our visitors out of their hotel rooms and onto the water.”

The 2013 seasonal forecast, made possible using NOAA models developed by NCCOS scientists, uses an 11-year data set of nutrients flowing into Lake Erie, collected by the Heidelberg University’s National Center for Water Quality Research, and analysis of satellite data from the European Space Agency’s Envisat. In addition to the satellite monitoring of the lake, NOAA’s Great Lakes Environmental Research  Laboratory, Ohio State University’s Sea Grant Program and Stone Laboratory, Heidelberg University, the University of Toledo, and Ohio EPA will be collecting key measurements from the lake as the summer progresses. Those results will provide valuable information to regional managers and assist NCCOS scientists in further refining the accuracy of this forecast’s models.

“Issuing and evaluating this seasonal forecast allows us to develop ways to help resource managers plan for conditions that will occur later in the summer,” said Richard Stumpf, Ph.D., NOAA’s ecological forecasting applied research lead at NCCOS. “Through partnerships with Heidelberg University and Ohio Sea Grant, we bring live tools to regional managers currently facing HAB challenges, but we are also constantly re-calibrating and evolving our forecasting products to meet changing HAB conditions.”

The NOAA forecast models and analyses draw on several sources, including nutrient data from Heidelberg University’s National Center for Water Quality Research and satellite data from
MERIS and NASA’s Moderate Resolution Imaging Spectro-radiometer. Funding to support the
program was provided through NCCOS, NOAA’s Center of Excellence for Great Lakes and Human Health, and NASA’s Applied Science Health and Air Quality Program.

The Lake Erie forecast is part of a NOAA ecological forecasting initiative that aims to deliver accurate, relevant, timely, and reliable ecological forecasts directly to coastal resource managers and the public as part of its stewardship and scientific mandates for coastal, marine and Great Lakes resources. Additionally, NOAA currently provides, or is developing, HABs and hypoxia forecasts for the Gulf of Maine, Chesapeake Bay, the Gulf of Mexico and the Pacific Northwest.

The National Centers for Coastal Ocean Science is the coastal science office for NOAA’s National Ocean Service. Visit our website or follow our blog to read more about NCCOS research.

Anne Smrcina, 781-545-8026 x204 Research reveals bottom feeding techniques of tagged humpback whales in Stellwagen Bank National Marine Sanctuary

New NOAA-led research on tagged humpback whales in Stellwagen Bank National Marine Sanctuary reveals a variety of previously unknown feeding techniques along the seafloor. Rather than a single bottom feeding behavior, the whales show three distinct feeding approaches: simple side-rolls, side-roll inversions, and repetitive scooping.

A recently published paper, in the journal Marine Mammal Science, indicates that bottom side-roll techniques are common in Stellwagen Bank National Marine Sanctuary and the Great South Channel study area, a deep-water passage between Nantucket, Mass. and Georges Bank-further southeast.

The study further states that the observed feeding behavior also leads to vulnerability to entanglement in bottom set fishing gear, an issue which is a major mortality factor for the species. This finding reaffirms a NOAA Fisheries regulation that mandates the use of sinking line between fishing traps used in the lobster fishery as a way of reducing entanglements.

The new findings follow earlier NOAA-led studies detailing so-called "bubble net" feeding behaviors near and at the surface. Bubble net feeding is a behavior in which humpback whales corral and contain fish into a small area by trapping them in nets of air bubbles so they can more efficiently scoop them up in their large filter-feeding mouths.The behaviors are used by individual animals and as part of coordinated feeding behaviors involving two or more animals.

"Tagging technology is allowing us to observe whales underwater, much as land-based biologists study animal subjects in their specific environments," said David Wiley, sanctuary research coordinator and a co-author on the paper. "The data have allowed us to detect new feeding techniques as well as nuances in those behaviors. We have determined that bottom feeding is a much more commonly used technique than the more well known bubble net behaviors."

Bottom side-rolling feeding was previously hypothesized from observations of scars on the jaws of humpback whales and from earlier tagging projects. In the recent studies, researchers showed that this behavior happens for extensive periods of time at or near the seafloor, that it occurs in the presence of concentrations of sand lance (a preferred prey fish), and that the behavior is accompanied by the expansion of the animal's ventral (throat) pleats.

Information was collected through the use of DTAGs (synchronous motion and acoustic recording tags) and Crittercam™, National Geographic Society's underwater video and audio recording system.

(Credit: NOAA/Stellwagen Bank National Marine Sanctuary )"By visualizing the data with TrackPlot, we can actually see how the whale moves underwater and this enables us to discover different kinds of foraging behaviors," said lead author Colin Ware of the University of New Hampshire's Center for Coastal and Ocean Mapping. TrackPlot is a custom software tool for DTAG data that produces a ribbon-like image in three dimensions. "With these 3-D visualizations, we can follow the path of the whale from surface to seafloor along with all of the pitch, roll and heading changes while underway. By adding Crittercam video, we now get a more complete understanding of these various bottom feeding techniques," Ware said.

A side-roll is defined as a roll of between 45 and 135 degrees from a normal orientation along the seafloor - the most common version uses a 90 degree roll with a downward head pitch of about 30 degrees, which matches favorably with earlier speculative sketches of bottom feeding. A side-roll inversion involves rolls that continue past the 135 degree orientation position. One humpback used a technique that employed a repetitive sequence of moves approximately every 20 feet during which the animal rolled from a 90 degree position to an inverted position, with some 10 to 17 of these "scoops" per dive.

(Credit: Colin Ware, University of New Hampshire Center for Coastal and Ocean Mapping)Sand lance, also known as sand eels, tend to burrow into the sandy sediments at night or form nighttime horizontal schools close to the seafloor. In addition, Crittercam footage indicates that sand lance can form dense mats along the seabed during the day. The side roll feeding technique with extended pleats emphasizes width rather than height, resulting in more efficient feeding when encountering prey at or near the seafloor. Coordinated feeding may also help cluster prey or simply ensure that it does not escape. Crittercam footage also showed for the first time a head-to-head orientation for two animals that were side-rolling at the seafloor.

While this humpback bottom feeding behavior occurs at relatively slow speeds, it does involve the expansion of ventral pleats, which was once thought to require high speeds, as in lunging. The researchers theorize that humpback side rolls may be similar to the feeding technique of gray whales in the Pacific. The three types of bottom feeding techniques may be due to different prey distributions or may just reflect individual preferences between whales. In this 3D computer visualization, the roller coaster-like movement of a tagged humpback whale in Stellwagen Bank National Marine Sanctuary is captured over a nearly two-hour period. The whale traveled at depths ranging from 30 to 150 feet deep. The red and blue triangles along the ribbon show the whale's powerful fluke, or tail fin strokes that propel it through the water. The yellow sections along the ribbons indicate where bottom side-roll feeding occurs. (Credit: Colin Ware, University of New Hampshire Center for Coastal and Ocean Mapping)

Scientists find large Gulf dead zone, but smaller than predicted

July 29, 2013

NOAA-supported scientists found a large Gulf of Mexico oxygen-free or hypoxic “dead” zone, but not as large as had been predicted. Measuring 5,840 square miles, an area the size of Connecticut, the 2013 Gulf dead zone indicates nutrients from the Mississippi River watershed are continuing to affect the nation’s commercial and recreational marine resources in the Gulf.

“A near-record area was expected because of wet spring conditions in the Mississippi watershed and the resultant high river flows which deliver large amounts of nutrients,” said Nancy Rabalais, Ph.D. executive director of the Louisiana Universities Marine Consortium (LUMCON), who led the July 21-28 survey cruise. “But nature’s wind-mixing events and winds forcing the mass of low oxygen water towards the east resulted in a slightly above average bottom footprint.”

Hypoxia is fueled by nutrient runoff from agricultural and other human activities in the watershed. These nutrients stimulate an overgrowth of algae that sinks, decomposes and consumes most of the oxygen needed to support life. Normally the low or no oxygen area is found closer to the Gulf floor as the decaying algae settle towards the bottom. This year researchers found many areas across the Gulf where oxygen conditions were severely low at the bottom and animals normally found at the seabed were swimming at the surface.

This is in contrast to 2012, when drought conditions resulted in the fourth smallest dead zones on record, measuring 2,889 square miles, an area slightly larger than Delaware. The largest previous dead zone was in 2002, encompassing 8,481 square miles. The smallest recorded dead zone measured 15 square miles in 1988. The average size of the dead zone over the past five years has been 5,176 square miles, more than twice the 1,900 square mile goal set by the Gulf of Mexico / Mississippi River Watershed Nutrient Task Force in 2001 and reaffirmed in 2008.

On June 18, NOAA-sponsored forecast models developed by Donald Scavia, Ph.D., University of Michigan, and R. Eugene Turner, Ph.D., Louisiana State University,  predicted the Gulf hypoxic zone would range in size from 7,286 to 8,561 square miles.

“NOAA’s investment in the Gulf of Mexico continues to yield results that confirm the complex dynamics of hypoxia and provide managers and the public with accurate scientific information for managing and restoring the nation's valuable coastal resources,” said Robert Magnien, Ph.D., director of NOAA’s Center for Sponsored Coastal Ocean Research. “For those who depend upon and enjoy the abundant natural resources of the Gulf of Mexico, it is imperative that we intensify our efforts to reduce nutrient pollution before the ecosystem degrades any further.”

This annual measurement provides federal and state agencies working on the 2008 Gulf task force implementation actions with the real consequences of inadequate nutrient pollution management. The task force’s actions are set for review this summer.

The hypoxic zone off the coast of Louisiana and Texas forms each summer threatening the ecosystem supporting valuable commercial and recreational Gulf fisheries that in 2011 had a commercial dockside value of $818 million and an estimated 23 million recreational fishing trips. The Gulf task force, in its 2008 report, states that "hypoxia has negative impacts on marine resources." It further states that research on living resources in the Gulf show long term ecological changes in species diversity and a large scale, often rapid change, in the ecosystem's food-web that is both "difficult and impossible to reverse." Additionally, there are numerous annual areas of the Gulf where large scale fish kills occur as a result of hypoxia.

Two surveys conducted in June and early July, one of which was led by a NOAA-supported Texas A&M University team, suggested a large hypoxic zone was forming in the Gulf, though the LUMCON July measurement will be the official one as required of NOAA by the Task Force. NOAA’s National Marine Fisheries Service, in conducting its Southeast Monitoring and Assessment Program groundfish surveys, also found large expanses of hypoxia in June-early July. Texas A&M will be conducting a follow-up cruise in mid-August to provide its final seasonal update.

NOAA’s National Ocean Service has been funding monitoring and research for the dead zone in the Gulf of Mexico since 1985 and currently oversees the NGOMEX program, the hypoxia research effort for the northern Gulf which is authorized by the Harmful Algal Bloom and Hypoxia Research and Control Act.

Possible record-setting dead zone for Gulf of Mexico

June 18, 2013

Dead zone.
Less oxygen dissolved in the water is often referred to as a “dead zone” (in red above) because most marine life either dies, or, if they are mobile such as fish, leave the area. Habitats that would normally be teeming with life become, essentially, biological deserts.

Scientists are expecting a very large “dead zone” in the Gulf of Mexico and a smaller than average hypoxic level in the Chesapeake Bay this year, based on several NOAA-supported forecast models.

NOAA-supported modelers at the University of Michigan, Louisiana State University, and the  Louisiana Universities Marine Consortium are forecasting that this year’s Gulf of Mexico hypoxic “dead” zone will be between 7,286 and 8,561 square miles which could place it among the ten largest recorded. That would range from an area the size of Connecticut, Rhode Island and the District of Columbia combined on the low end to the New Jersey on the upper end. The high estimate would exceed the largest ever reported 8,481 square miles in 2002 .

Hypoxic (very low oxygen) and anoxic (no oxygen) zones are caused by excessive nutrient pollution, often from human activities such as agriculture, which results in insufficient oxygen to support most marine life in near-bottom waters. Aspects of weather, including wind speed, wind direction, precipitation and temperature, also impact the size of dead zones.

The Gulf estimate is based on the assumption of no significant tropical storms in the two weeks preceding or during the official measurement survey cruise scheduled from July 25-August 3 2013.  If a storm does occur the size estimate could drop to a low of 5344 square miles, slightly smaller than the size of Connecticut.

This year’s prediction for the Gulf reflect flood conditions in the Midwest that caused large amounts of nutrients to be transported from the Mississippi watershed to the Gulf. Last year’s dead zone in the Gulf of Mexico was the fourth smallest on record due to drought conditions, covering an area of approximately 2,889 square miles, an area slightly larger than the state of Delaware. The overall average between 1995-2012 is 5,960 square miles, an area about the size of Connecticut.

A second NOAA-funded forecast, for the Chesapeake Bay, calls for a smaller than average dead zone in the nation's largest estuary. The forecasts from researchers at the University of Maryland Center for Environmental Science  and the University of Michigan has three parts: a prediction for the mid-summer volume of the low-oxygen hypoxic zone, one for the mid-summer oxygen-free anoxic zone, and a third that is an average value for the entire summer season.

The forecasts call for a mid-summer hypoxic zone of 1.46 cubic miles, a mid-summer anoxic zone of 0.26 to 0.38 cubic miles, and a summer average hypoxia of  1.108 cubic miles, all at the low end of previously recorded zones.  Last year the final mid-summer hypoxic zone was 1.45 cubic miles.

This is the seventh year for the Bay outlook which, because of the shallow nature of large areas of the estuary, focuses on water volume or cubic miles, instead of square mileage as used in the Gulf. The history of hypoxia in the Chesapeake Bay since 1985 can be found at the EcoCheck website.

Both forecasts are based on nutrient run-off and river stream data from the U.S. Geological Survey (USGS), with the Chesapeake data funded with a cooperative agreement between USGS and the Maryland Department of Natural Resources.  Those numbers are then inserted into models developed by funding from the National Ocean Service’s National Centers for Coastal Ocean Science (NCCOS).

"Monitoring the health and vitality of our nation’s oceans, waterways, and watersheds is critical as we work to preserve and protect coastal ecosystems,” said Kathryn D. Sullivan, Ph.D., acting under secretary of commerce for oceans and atmosphere and acting NOAA administrator.  “These ecological forecasts are good examples of the critical environmental intelligence products and tools that help shape a healthier coast, one that is so inextricably linked to the vitality of our communities and our livelihoods.”

The dead zone in the Gulf of Mexico affects nationally important commercial and recreational fisheries, and threatens the region’s economy. The Chesapeake dead zones, which have been highly variable in recent years, threaten a multi-year effort to restore the Bay’s water quality and enhance its production of crabs, oysters, and other important fisheries.

During May 2013, stream flows in the Mississippi and Atchafalaya rivers were above normal resulting in more nutrients flowing into the Gulf. According to USGS estimates, 153,000 metric tons of nutrients flowed down the rivers to the northern Gulf of Mexico in May, an increase of 94,900 metric tons over last year’s 58,100 metric tons, when the region was suffering through drought. The 2013 input is an increase of 16 percent above the average nutrient load estimated over the past 34 years.

For the Chesapeake Bay, USGS estimates 36,600 metric tons of nutrients entered the estuary from the Susquehanna and Potomac rivers between January and May, which is 30 percent below the average loads estimated from1990 to 2013.

“Long-term nutrient monitoring and modeling is key to tracking how nutrient conditions are changing in response to floods and droughts and nutrient management actions,” said Lori Caramanian, deputy assistant secretary of the interior for water and science. “Understanding the sources and transport of nutrients is key to developing effective nutrient management strategies needed to reduce the size of hypoxia zones in the Gulf, Bay and other U.S. waters where hypoxia is an on-going problem.”

“Coastal hypoxia is proliferating around the world,” said Donald Boesch, Ph.D., president of the University of Maryland Center for Environmental Science. “It is important that we have excellent abilities to predict and control the largest dead zones in the United States. The whole world is watching.”

The confirmed size of the 2013 Gulf hypoxic zone will be released in August, following a monitoring survey led by the Louisiana Universities Marine Consortium beginning in late July, and the result will be used to improve future forecasts. The final measurement in the Chesapeake will come in October following surveys by the Chesapeake Bay Program’s partners from the Maryland Department of Natural Resources and the Virginia Department of Environmental Quality.

Despite the Mississippi River/Gulf of Mexico Nutrient Task Force’s goal to reduce the dead zone to less than 2,000 square miles, it has averaged 5,600 square miles over the last five years. Demonstrating the link between the dead zone and nutrients from the Mississippi River, this annual forecast continues to provide guidance to federal and state agencies as they work on the 11 implementation actions outlined by the Task Force in 2008 for mitigating nutrient pollution.

NOAA’s National Ocean Service has been funding investigations and forecast development for the dead zone in the Gulf of Mexico since 1990, and oversees national hypoxia research programs which include the Chesapeake Bay and other affected bodies of water.

USGS operates more than 3,000 real-time stream gages and collects water quality data at numerous long-term stations throughout the Mississippi River basin  and the Chesapeake Bay to track how nutrient loads are changing over time.

Federal agencies remapping coastal areas damaged by Hurricane Sandy

August 20, 2013

A day after the administration released the Hurricane Sandy Rebuilding Task Force progress report, three federal agencies have announced plans for remapping parts of the East Coast, where Hurricane Sandy altered seafloors and shorelines, destroyed buildings, and disrupted millions of lives last year.

NOAA, the U.S. Geological Survey, and the U.S. Army Corps of Engineers are using emergency supplemental funds provided by Congress to survey coastal waters and shorelines, acquiring data that will update East Coast land maps and nautical charts.

Using ships, aircraft, and satellites, the agencies will measure water depths, look for submerged debris, and record altered shorelines in high priority areas from South Carolina to Maine, as stipulated by Congress in the Disaster Relief Appropriations Act of 2013. The areas to be remapped will be based on their relative dangers to navigation, effects from the storm, and discussions with state and local officials as well as the maritime industry.

“Our approach is to map once, then use the data for many purposes,” said NOAA Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “Under the Ocean and Coastal Mapping Integration Act, NOAA and its federal partners are taking a 'whole ocean' approach to get as much useful information as possible from every dollar invested to help states build more resilient coastlines.”

The data, much of which will be stored at NOAA’s National Geophysical Data Center, and through NOAA’s Digital Coast, will be open to local, state, and federal agencies as well as academia and the general public. The information can be applied to updating nautical charts, removing marine debris, replenishing beaches, making repairs, and planning for future storms and coastal resilience.

The three federal agencies are collaborating for greater topographic and hydrographic coverage and to promote efficiency. Earlier this year, a NOAA navigation response team surveyed the waters around Liberty Island and Ellis Island in New York harbor, measuring water depths and searching for debris that could cause a danger to navigation. Also, NOAA Ship Thomas Jefferson began surveying the approaches to the Delaware Bay in June.

NOAA plans to contract with commercial firms for additional hydrographic survey projects and high resolution topographic and bathymetric elevation data and imagery in the region.

The U.S. Geological Survey will collect very high-resolution elevation data to support scientific studies related to the hurricane recovery and rebuilding activities, watershed planning and resource management. USGS will collect data in coastal and inland areas depending on their hurricane damages and the age and quality of existing data. The elevation data will become part of a new initiative, called the 3D Elevation Program, to systematically acquire improved, high-resolution elevation data across the United States.

Bay Hydro II returns to Norfolk: Within hours of Sandy's departure, NOAA deployed research vessel Bay Hydro II to survey ship channels in the Hampton Roads area of Virginia, speeding the resumption of shipping and naval operations.

“The human deaths and the powerful landscape-altering destruction caused by Hurricane Sandy are a stark reminder that our nation must become more resilient to coastal hazards,” said Kevin Gallagher, associate director for Core Science Systems at USGS. "Sandy's most fundamental lesson is that storm vulnerability is a direct consequence of the elevation of coastal communities in relation to storm waves. Communities will benefit greatly from the higher resolution and accuracy of new elevation information to better prepare for storm impacts, develop response strategies, and design resilient and cost-efficient post-storm redevelopment."

The Army Corps of Engineers and its Joint Airborne Lidar Bathymetry Technical Center of Expertise are covering particular project areas in Massachusetts, Virginia, and New Jersey. They will coordinate operations, research, and development in airborne lidar bathymetry and complementary technologies for USACE, NOAA, and the U.S. Navy.

Preliminary U.S. damage estimates are near $50 billion, making Sandy the second-costliest cyclone to hit the United States since 1900. 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. This is the greatest number of U.S. direct fatalities related to a tropical cyclone outside of the southern states since Hurricane Agnes in 1972.

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.

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:

Heat Wave and Drought in United States:

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. 

The report was edited by Peterson, along with Martin P. Hoerling, NOAA’s Earth System Research Laboratory; Peter A. Stott, UK Met Office Hadley Centre and Stephanie C. Herring of NCDC and written by 78 scientists from 11 countries. View the full report online.

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.

A CO-OPS employee installs an air gap sensor which measures bridge clearance on the Don Holt Bridge in Charleston, South Carolina. The sensor is part of the Charleston Harbor Physical Oceanographic Real-Time System (or PORTS®). Information from the sensor is critical for under bridge clearance, as ships continue to maximize channel depths and widths while, at the same time, push the bounds of bridge heights.

Officials from NOAA’s National Ocean Service and the South Carolina State Ports Authority will officially dedicate a new system to increase safety for ships in the harbor of Charleston, S.C. today.

The system, called Physical Oceanographic Real-Time System (PORTS®), provides real-time information that determines bridge clearance measurements from special air gap sensors, as well as water level and meteorological information from long-term tide stations, providing users with critical data when transiting the harbor. Charleston will become the 23rd U.S. harbor to use the system.

“By providing integrated real-time tide, weather and bridge clearance information, the Charleston PORTS will help reduce the chances for accidents,” said Richard Edwing, director of NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS). “For instance, the new sensors on the Don Holt Bridge in the harbor will provide crucial information for ships trying to pass under it. Also, enhanced marine information can increase the amount of cargo moved through a port and harbor by enabling mariners to safely use every inch of dredged channel depth and bridge clearance.”

Tailored to the specific requirements of each seaport, PORTS is a decision support tool that improves the safety and efficiency of maritime commerce and coastal resource management through the integration of real-time environmental observations, forecasts, and other geospatial information.

Knowledge of the currents, water levels, winds, and density of the water can increase the amount of cargo moved through a port and harbor by enabling mariners to safely utilize every inch of dredged channel depth. One additional foot of draft can increase profit per transit depending on the type of cargo transported.

The Port of Charleston is the fourth largest port on the East Coast handling commerce valued at more than $58 billion a year. It is a major economic driver of the region and state, facilitating 260,800 jobs in South Carolina. More than 20,000 companies in two dozen states use the Port of Charleston, including major global brands like Michelin, BMW, Adidas, Starbucks and Boeing.

“We consider the PORTS air gap system’s capability to provide real-time data as absolutely necessary for both navigation safety and the continued business development and job creation at our port facility,” said Stevenson E. Kemp Jr., Vice President, Terminal Operations, Port of Charleston.

In addition to providing useful information for maritime transportation, the use of the water temperature and tidal data can be used by fishers to improve their catch, while recreational boating excursions can occur more often and be safer through better real-time information available through PORTS.

Two major studies of the economic benefits of the PORTS system have shown that it can provide significant annual economic benefits in both cost-savings and in higher direct income. A 2007 study of PORTS operations in the Houston/Galveston areas showed benefits ranging between $14.1 and $15.6 million annually. An earlier study for the system operated in Tampa/St.Petersburg showed that the Tampa Bay economy receives more than $7 million a year in savings and direct income from NOAA PORTS.

CO-OPS, as part of NOAA’s National Ocean Service, is an organization of experts in understanding tides, currents and water levels, turning operational oceanographic data into meaningful information, products and services for the nation.

Report highlights climate change threats to nation’s estuaries

August 7, 2013

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.
