Explore Oil Spill Data for Gulf of Mexico Marine Life With NOAA GIS Tools

In the wake of the Deepwater Horizon oil spill, the sheer amount of data scientists were gathering from the Gulf of Mexico was nearly overwhelming. Everything from water quality samples to the locations of oiled sea turtles to photos of dolphins swimming through oil—the list goes on for more than 13 million scientific records.

So, how would anyone even start to dig through all this scientific information? Fortunately, you don’t have to be a NOAA scientist to access, download, or even map it. We have been building tools to allow anyone to access this wealth of information on the Gulf of Mexico environment following the Deepwater Horizon oil spill.

We’re taking a look at two of our geographic information systems tools and how they help scientists, emergency responders, and the public navigate the oceans of environmental data collected since the 2010 Deepwater Horizon oil spill.

When it comes to mapping and understanding huge amounts of these data, we turn to our GIS-based tool, the Environmental Response Management Application, known as ERMA®. This online mapping tool is like a Swiss army knife for organizing data and information for planning and environmental emergencies, such as oil spills and hurricanes.

ERMA not only allows pollution responders to see real-time information, including weather information and ship locations, but also enables users to display years of data, revealing to us broader trends.

In the “Layer” tab on the right side of the screen, you can choose which groups of data, or “layers,” to display in ERMA. Right click on a data layer, such as “Turtle Captures Probability of Oiling (NOAA) (PDARP),” and select “View metadata” to view more information about the data being shown. (NOAA)

For instance, say you want to know the likelihood of sea turtles being exposed to heavy oil during the Deepwater Horizon oil spill. ERMA enables you to see where sea turtles were spotted during aerial surveys or captured by researchers across the Gulf of Mexico between May and September 2010. At the same time, you can view data showing the probability that certain areas of the ocean surface were oiled (and for how long), all displayed on a single, interactive map.

Clicking on the “Legend” tab on the right side of the screen shows you basic information about the data displayed in ERMA. Here, the red area represents portions of the Gulf of Mexico which had the highest likelihood of exposing marine life to oil. Triangles show sea turtle sightings and squares show sea turtle captures between May and September 2010. The color of the symbol indicates the likelihood of that sea turtle receiving heavy exposure to oil. (NOAA)

Perhaps you want to focus on where Atlantic bluefin tuna were traveling around the Gulf and where that overlaps with the oil spill’s footprint. Or compare coastal habitat restoration projects with the degree of oil different sections of shoreline experienced. ERMA gives you that access.

You can use ERMA Deepwater Gulf Response to find these data in a number of ways (including search) and choose which GIS “layers” of data to turn on and off in the map. To see the most recently added data, click on the “Recent Data” tab in the upper left of the map interface, or find data by browsing through the “Layers” tab on the right. Or look for data in special “bookmark views” on the lower right of the “Layers” tab to find data for a specific topic of interest.

Now, what if you not only want to see a map of the data, what if you also want to explore any trends in the data at a deeper level? Or download photos, videos, or scientific analyses of the data?

That’s where our data management tool DIVER comes in. This tool serves as a central repository for environmental impact data from the oil spill and was designed to help researchers share and find scientific information ranging from photos and field notes to sample data and analyses.

As Ocean Conservancy’s Elizabeth Fetherston put it:

Until recently, there was no real way to combine all of these disparate pixels of information into a coherent picture of, for instance, a day in the life of a sea turtle. DIVER, NOAA’s new website for Deepwater Horizon assessment data, gives us the tools to do just that.

Data information and integration systems like DIVER put all of that information in one place at one time, allowing you to look for causes and effects that you might not have ever known were there and then use that information to better manage species recovery. These data give us a new kind of power for protecting marine species.

One of the most important features of DIVER, called DIVER Explorer, is the powerful search function that allows you to narrow down the millions of data pieces to the precise set you’re seeking. You do it one step, or “filter,” at a time.

For example, when you go to DIVER Explorer, click on “Guided Query” at the top and then “Start to Explore Data,” choose “By Workplan Topic Area,” hit “Next,” and finally select “Marine Mammals” before clicking “Run Query” to access information about scientific samples taken from marine mammals and turtles. You can view it on a map, in a table, or download the data to analyze yourself.

An even easier way to explore these data in DIVER, however, is by visiting and scrolling down to and clicking on #5 Preassessment/Assessment (§§ 990.40 – 990.45; 990.51). This will reveal a list of various types of environmental impacts—to birds, sea floor habitat, marine mammals, etc.—which the federal government studied as part of the Deepwater Horizon oil spill’s Natural Resource Damage Assessment.

Say you’re interested in marine mammals, so you click on 5.6 Marine Mammal Injury and then 5.6.3 Data sets. You can then download and open the document “NOAA Marine Mammal data related to the Deepwater Horizon incident, available through systems such as DIVER and ERMA, or as direct downloads. (September 23, 2015).”

Under the section “Data Links,” you can choose from a variety of stored searches (or “queries”) in DIVER that will show you where and when, for example, bottlenose dolphins with satellite tags traveled after the spill (tip: zoom in to view this data on the map)—along with photographs to go with it (tip: click on the “Photos” tab under the map to browse).

A map view of DIVER shows where tagged dolphins traveled along the Gulf Coast, showing two populations that stayed in their home bases of Barataria Bay and Mississippi Sound. (NOAA)

This can tell us key information, such as the fact that certain populations of dolphins stay in the same areas along the coast, meaning they don’t travel far from home. We can also look at data about whether those dolphin homes were exposed to a lot of oil, which would suggest that the dolphins that lived there likely were exposed to oil again and again.

Both of these tools allow us to work with incredible amounts of data and see their stories brought to life through the power of geographic information systems. So, go ahead and start exploring!

Remembering the Veterans That Served America and the Historic Shipwrecks They Left Behind

This is a post by the Office of Response and Restoration’s Donna Roberts.

Did you know that over 20,000 shipwrecks rest on the ocean floor off our coasts? The past century of commerce and warfare has left us with this legacy of sunken vessels dotting the seafloor around the United States.

While some of these are naval vessels, a large proportion are merchant vessels destroyed during war time. These wrecks are skewed heavily to World War II casualties such as those fallen during the “Battle of the Atlantic.” Some wrecks, such as the Civil War casualty, the USS Monitor, have been listed as National Historic Landmarks or on the National Register of Historic Places. Many of them, such as the USS Arizona at Pearl Harbor, Hawaii, are either civilian or military grave sites.

Beyond their military and historic significance, these wrecks also represent an enormous human toll. Today—on Veterans Day in the United States, Armistice Day or Remembrance Day in other nations—we honor the men and women who have served in the armed forces of all nations, as well as those serving in the Merchant Marine, and commemorate those who gave their lives in that service.

The Terrible Cost of the Battle of the Atlantic

During World War II’s Battle of the Atlantic, which lasted from September 1939 until the defeat of Germany in 1945, German U-boats and warships (and later Italian submarines) were pitted against Allied convoys transporting military equipment and supplies across the Atlantic to Great Britain and the Soviet Union. This battle to control Atlantic shipping lanes involved thousands of ships and stretched across thousands of square miles of ocean.

A Coast Guard ship's crew watches an explosion in the water ahead.

On April 17, 1943, Coast Guardsmen on the deck of the U.S. Coast Guard Cutter Spencer watch the explosion of a depth charge that blasted a Nazi U-boat’s hope of breaking into the center of a large convoy of ships. World War II left thousands of Allied and Axis ships — and soldiers — on the bottom of the ocean. (U.S. Coast Guard)

The losses in the battle were staggering. Between January and June 1942 alone, this battle resulted in the sinking of almost 500 ships. Historians estimate that more than 100 convoy battles took place during the war, costing Britain’s Merchant Navy more than 30,000 men and around 3,000 ships. The terrible cost for the Germans was 783 U-boats and 28,000 sailors, about 75% of the U-boat force. Although casualty statistics vary, we know that the U.S. Merchant Mariners suffered the highest rate of marine casualties of any service in World War II.

While many of these sunken vessels in U.S. waters rest in the Atlantic Ocean or Gulf of Mexico, numerous wrecks, such as the S/S Montebello, can be found in the Pacific. And of course, the wartime toll was spread across the world’s oceans, touching nearly all parts of the globe.

NOAA’s Role with Undersea Wrecks

NOAA is involved with shipwrecks in a number of ways. The agency’s role ranges from offering scientific guidance to the U.S. Coast Guard during pollution responses, to stewarding the diverse natural and cultural resources including shipwrecks in national marine sanctuaries, to creating navigational charts that show the precise locations of wrecks that could hinder maritime traffic. Most of the 20,000 wrecks resting off our coasts are old and did not carry oil as fuel or hazardous cargo; however, some of the more recent wrecks have the potential to contain—and sometimes leak—oil.

In 2002, for example, the decaying wreck of the S/S Jacob Luckenbach (carrying supplies to support the Korean War) was identified as the source of mysterious, recurring oil spills that had killed thousands of seabirds and other marine life along California’s coast. Our office joined with the U.S. Coast Guard and other agencies to remove the approximately 100,000 gallons of oil remaining in the wreck, protect the resources of the Great Farallones National Marine Sanctuary, and restore critical seabird breeding habitat in the U.S. and Canada to make up for the harm caused by the oil releases.

Knowing how shipwreck sites formed helps explain why sunken vessels, like the Dixie Arrow which initially carried approximately 86,136 barrels of crude oil, but was demolished during World War II, no longer remain intact and are no longer potentially polluting shipwrecks. (NOAA)

Leaking wrecks like the Jacob Luckenbach are one reason NOAA maintains a large database of shipwrecks, dumpsites, navigational obstructions, underwater archaeological sites, and other underwater cultural resources, known as the Resources and Undersea Threats (RUST) database.

Beginning in 2010, NOAA’s Office of Response and Restoration and Office of National Marine Sanctuaries systematically analyzed a subset of those wrecks which could pose a substantial threat of leaking oil still on board. This work is part of NOAA’s Remediation of Underwater Legacy Environmental Threats (RULET) project. (Read more about the work conducted and the final report (PDF).) After the report was completed in 2013, the U.S. Coast Guard has worked to incorporate the information and recommendations into their regional contingency plans.

NOAA also has the privilege of protecting shipwrecks and naval battlefields though its National Marine Sanctuaries office. The first NOAA national marine sanctuary was designated in 1975 to protect the U.S. Navy warship USS Monitor, and other sanctuaries have followed in these footsteps of preserving historic wrecks. Today, you can explore fascinating undersea wrecks at Florida Keys National Marine Sanctuary, Thunder Bay National Marine Sanctuary in the Great Lakes, and at other sanctuaries.

Wrecks and Reefs

Sometimes these submerged shipwrecks can serve as artificial reefs. Sunken wrecks are actually the most prevalent type of artificial reef. As artificial reefs, shipwrecks can create both amazing homes for a diversity of marine life and popular attractions for commercial and recreational fishers, divers, and snorkelers.

Occasionally, vessels are even sunk intentionally for this purpose. However, it can be very costly to prepare the vessels to become artificial reefs, which requires removing paints and other hazardous materials in the hull. Another consideration is the stability of the vessel and its danger to living things around it. For example, if the vessel is in shallow water, will it flip over in a storm and crush the new coral growing there? Could people or marine life get caught inside it? These considerations are why artificial reefs are often found in deep water and why establishing an artificial reef requires special review and permitting processes.

Through the study, protection, and promotion of our diverse legacy of undersea wrecks, national marine sanctuaries help us learn more about and celebrate our merchant marine and military history.

Explore Shipwrecks While Staying Dry

You can learn more about NOAA expeditions between 2008 and 2011, which explored the World War II wrecks in the “Graveyard of the Atlantic.”

You also can watch a video of researchers first discovering the long-lost location of the USS Monitor’s wreck in 1973 off the coast of North Carolina:

Stepping on Board the Most Eerie, Neglected Ship I Had Ever Seen

This is a post by the Office of Response and Restoration’s LTJG Rachel Pryor, Northwest Regional Response Officer.

Before Friday, October 9, 2015, I had never set foot on an abandoned ship. Or for that matter, any other manmade structure so neglected that trees were growing out of it.

But on that day, I was invited to accompany three members of the U.S. Coast Guard here in Seattle, Washington, to investigate a tugboat which was reported to be abandoned and only four inches away from sinking. After a quick glance at the rusting, eerie hulk barely afloat in a ship canal, my bets were on it being abandoned too.

Once at the docks, we met pollution responders from the State of Washington and a local salvage company. After taking stock of the neglected vessel and its surrounding conditions, we boarded the vessel and began conducting an investigation. The Coast Guard inspected the engine room first, where they measured how much water currently was flooding the tug’s engine room. Then, they made note of any hazardous materials nested in cupboards and on shelves—large industrial batteries, paint cans, or lubricants—that would require special disposal.

My favorite part was rummaging through the galley, captain’s quarters, and the bridge. The living areas on board the vessel appeared ransacked. For starters, the helm had been removed and copper wires from the fire panel were missing.

However, we were looking for any information on the layout of the vessel in order to answer a number of questions. How many fuel tanks were on board and how large were they? Where were the ballast tanks? Who was the last owner or when was the last log entry in the book recording the engine’s oil changes?

Unfortunately, our search that day turned up empty, aside from a cluttered mess of clothes, a half-used bottle of aspirin, some books, and a pile of empty beer cans resembling bones in an open graveyard.

Our only clues leading to who owned this boat were a chalkboard message left to the owner by a shipmate and a left-behind DVD from the movie rental kiosk company Redbox. The movie was Couples Retreat, which was released in 2009, suggesting someone previously on board had a soft spot for romantic comedies and now owes Redbox a sizable bill for this dollar-per-day rental.

The last moorage payment the dock facility received for this boat was in 2008. Since then, the vessel has been slowly withering away and nature is creeping in. Trees and moss grow freely in cracks and crevices, eating away at the ship’s structure.

While the Coast Guard will pay for the salvage company to pump the water out of the engine room and fix the leak to keep the vessel from sinking, they do not have the funds or jurisdiction to get rid of the derelict tug. The problem of abandoned vessels is a recurring, expensive, and polluting one, which a NOAA colleague also learned firsthand:

“These neglected ships often pose significant threats to fish, wildlife, and nearby habitat, in addition to becoming eyesores and hazards to navigation. Derelict vessels are a challenge to deal with properly because of ownership accountability issues, potential chemical and oil contamination, and the high cost of salvage and disposal. Only limited funds are available to deal with these types of vessels before they start sinking.”

And, tied to a pier in Seattle, yet another decaying vessel will remain haunted by the remnants of those who abandoned it and will continue to haunt our waterways as well.

Editor’s note: Stay tuned for a special series in early November when we’ll be diving deeper into the issues of sunken, abandoned, and derelict vessels—covering everything from when they become maritime heritage sites to how we deal with those that turn into polluting eyesores.

NOAA Involved After Barge Argo, the Lake Erie Shipwreck Lost in 1937, Resurfaces with Oily Leak in U.S. Waters

Divers exit small boats into the waters of Lake Erie.

Contractors conduct dive operations at the site of a sunken barge near the Kelley’s Island Shoal in Lake Erie, Oct. 21, 2015. The divers were trying to establish the identity of the barge and if it or any of its cargo poses an environmental threat. (U.S. Coast Guard)

The 1937 sinking of a small barge in Lake Erie went largely unnoticed at the time, but the ill-fated tank barge Argo is in the news now that the wreck’s exact location—along with a leak—has been discovered.

And it wasn’t in Canadian waters, as previously thought.

Ship Down, Pollution Rising

That piece of underwater detective work by the Cleveland Underwater Explorers, combined with historical research done as part of NOAA’s RULET program (Remediation of Underwater Legacy Environmental Threats) which in 2013 identified it as a potentially polluting shipwreck, have been key factors in the developing response to the Argo.

Recently found to be on the U.S. side of the border with Canada, the wreck has been traced to reports of pollution on Lake Erie in both nations, indicating that the Argo is leaking. At the time of the sinking, the barge was reportedly loaded with 4,762 barrels of crude oil and the chemical benzol. The U.S. Coast Guard, with support from NOAA’s Office of Response and Restoration and in collaboration with Canada, is ramping up pollution response efforts to address the leaking Great Lakes wreck.

While underwater response technologies do exist to address wrecks filled with oil, there are a lot of steps involved before a wreck can be safely remediated. Early efforts will focus on identifying whether the barge is leaking petroleum or benzol (or both) and determining whether the source of the leaks can be controlled immediately.

The Coast Guard is evaluating whether and how to safely remove the cargo from the sunken barge to reduce the likelihood of future pollution. NOAA is providing environmental and chemical data, weather forecasting, modeling of observed oil sheens back to the wreck, and other observations to support the response.

Linking Leaks to Potential Harm

Evaluating the magnitude of the leaks will alert us to any significant threats to people or to fish, birds, or other wildlife in the lake. NOAA and other organizations are analyzing samples of lake water and zebra mussels attached to the wreck to determine whether concentrations of hazardous chemicals are present or exceed levels of concern.

If it appears that the Argo has been leaking for some time or if the concentrations of detected pollutants are expected to be toxic to fish or wildlife, NOAA and other agencies would consider pursuing a natural resource damage assessment, with the goal of evaluating harm to public natural resources and determining whether and which restoration actions would compensate for injuries. As “natural resource trustee” agencies, NOAA, U.S. Fish and Wildlife Service, and the State of Ohio would perform these assessments over the next few months.

From Another Time

One of the compelling aspects of shipwrecks is the way they capture a moment in time. Looking back at the major events of that time, it is easy to see how a barge accident in the Great Lakes would barely garner a mention in the local papers. In 1937 Franklin Roosevelt had just been re-elected president, Adolf Hitler was chancellor of Germany, Benito Mussolini was prime minister of Italy, and Joseph Stalin was in power in the Soviet Union.

Even in the area of transportation, other momentous events dominated the news. The Golden Gate Bridge had just opened, the zeppelin Hindenburg was destroyed by fire while landing in New Jersey, and American aviation pioneer Amelia Earhart disappeared over the Pacific.

Yes, 1937 was a long time ago. It was well before the Oil Pollution Act of 1990 and other laws and regulations for the transport of oil and response to spills. When the Argo sank in a storm on October 20—79 years ago—the crew was safely rescued and the barge was left on the bottom, slowly sinking into the lake bed sediments.

The location wasn’t well known, even to maritime historians. We weren’t even sure if the wreck was in the U.S. or Canada, which shows how little is often known about the thousands of shipwrecks in North American waters—that is, until they start releasing their long-hidden cargo.

Stay tuned for a special series in early November when we’ll be diving deeper into the issues of sunken, abandoned, and derelict vessels—covering everything from when they become maritime heritage sites to how we deal with those that turn into polluting eyesores.

Visualizing How Ocean Currents Help Create the Garbage Patches

Plastic water bottle floating in the ocean.

The “garbage patches” are not giant, floating islands of trash, but rather, ocean gathering places for what are mainly tiny bits of plastic dispersed throughout the water column, with some larger items as well. (NOAA)

The data whizzes at NASA recently decided to turn their attention from the sky to the ocean as they attempted to model how ocean currents help drive the formation of the “garbage patches.” From NASA:

“We start with data from floating, scientific buoys that NOAA has been distributing in the oceans for the last 35 years represented here as white dots … If we let all of the buoys go at the same time, we can observe buoy migration patterns … The buoys migrate to 5 known gyres also called ocean garbage patches.

We can also see this in a computational model of ocean currents called ECCO-2. We release particles evenly around the world and let the modeled currents carry the particles. The particles from the model also migrate to the garbage patches.”

Check out their data visualization here:

As you might gather from the visualization, the gyres, where “garbage patches” are located, represent massive, dynamic areas of the ocean that are constantly moving and changing—and as a result, are also bringing trash and other marine debris with them. Rather than giant, floating islands of trash that you can see from satellites (you can’t), “garbage patches” are ocean gathering places for what are mainly tiny bits of plastic dispersed throughout the water column.

Still fuzzy on what the garbage patches are and are not? Check out this video from the NOAA Marine Debris Program:

And tune in to this National Ocean Service podcast to learn what we know and don’t know about the garbage patches and what we can do about this ocean-sized problem:

You can also read about our own efforts to model where marine debris travels across the ocean.

NOAA, Deepwater Horizon Trustees announce draft restoration plans for Gulf of Mexico following 2010 disaster

These efforts will restore wildlife and habitat in the Gulf by addressing the ecosystem injuries that resulted from the Deepwater Horizon incident. (NOAA)

NOAA and the other Deepwater Horizon Natural Resource Trustees today released 15-year comprehensive, integrated environmental ecosystem restoration plans for the Gulf of Mexico in response to the April 20, 2010 Deepwater Horizon oil rig explosion and spill.

Implementing the plan will cost up to $8.8 billion. The explosion killed 11 rig workers and the subsequent spill lasted 87 days and impacted both human and natural resources across the Gulf.

The Draft Deepwater Horizon Oil Spill Draft Programmatic Damage Assessment and Restoration Plan and Draft Programmatic Environmental Impact Statement allocates Natural Resource Damage Assessment  monies that are part of a comprehensive settlement agreement in principle  among BP, the U.S. Department of Justice on behalf of federal agencies, and the five affected Gulf States announced on July 2, 2015. The Department of Justice lodged today in U.S. District Court a consent decree as part of the more than $20 billion dollar settlement.

In the draft plan, the Trustees provide documentation detailing impacts from the Deepwater Horizon oil spill to:

  • wildlife, including fish, oysters, plankton, birds, sea turtles, and marine mammals across the Gulf
  • habitat, including marshes, beaches, floating seaweed habitats, water column, submerged aquatic vegetation, and ocean-bottom habitats
  • recreational activities including boating, fishing, and going to the beach

The Trustees determined that “overall, the ecological scope of impacts from the Deepwater Horizon spill was unprecedented, with injuries affecting a wide array of linked resources across the northern Gulf ecosystem.” As a result of the wide scope of impacts identified, the Trustees “have determined that the best method for addressing the injuries is a comprehensive, integrated, ecosystem restoration plan.”

Both the consent decree and the draft plan are available for 60 days of public comment. The Trustees will address public comment in adopting a final plan. For the consent decree, once public comment is taken into account the court will be asked to make it final.

Public comments on the draft plan will be accepted at eight public meetings to be held between October 19 and November 18 in each of the impacted states and in Washington, DC. Comments will also be accepted online and by mail sent to: U.S. Fish and Wildlife Service, P.O. Box 49567, Atlanta, GA 30345. The public comment period will end on December 4, 2015.

The Trustees are proposing to accept this settlement, which includes, among other components, an amount to address natural resource damages of $8.1 billion for restoration and up to $700 million for addressing unknown impacts or for adaptive management. These amounts include the $1 billion in early restoration funds which BP has already committed.

“NOAA scientists were on the scene from day one as the Deepwater spill and its impacts unfolded. NOAA and the Trustees have gathered thousands of samples and conducted millions of analyses to understand the impacts of this spill,” said Kathryn D. Sullivan, Ph.D., undersecretary of commerce for oceans and atmosphere and NOAA administrator. “The scientific assessment concluded that there was grave injury to a wide range of natural resources and loss of the benefits they provide. Restoring the environment and compensating for the lost use of those resources is best achieved by a broad-based ecosystem approach to restore this vitally important part of our nation’s environmental, cultural and economic heritage.”

The draft plan has an array of restoration types that address a broad range of impacts at both regional and local scales. It allocates funds to meet five restoration goals, and 13 restoration types designed to meet these goals. (NOAA)

NOAA led the development of the 1,400 page draft damage assessment and restoration plan, with accompanying environmental impact statement, in coordination with all of the natural resource Trustees. The draft plan is designed to provide a programmatic analysis of the type and magnitude of the natural resources injuries that have been identified through a Natural Resource Damage Assessment conducted as required by the Oil Pollution Act of 1990 and a programmatic restoration plan to address those injuries. Alternative approaches to restoration are evaluated in the plan under the Oil Pollution Act and the National Environmental Policy Act.

Specific projects are not identified in this plan, but will be proposed in future project-specific restoration proposals. The Trustees will ensure that the public is involved in their development through public notice of proposed restoration plans, opportunities for public meetings, and consideration of all comments received.

The draft plan has an array of restoration types that address a broad range of impacts at both regional and local scales. It allocates funds to meet five restoration goals, and 13 restoration types designed to meet these goals.

The five overarching goals of the proposed plan are to:

  • restore and conserve habitat
  • restore water quality
  • replenish and protect living coastal and marine resources
  • provide and enhance human use recreational activities
  • provide for long term monitoring, adaptive management, and administrative oversight of restoration efforts.

The 13 proposed restoration activities are:

  1. Restoration of wetlands, coastal, and nearshore habitats
  2. Habitat projects on federally managed lands
  3. Nutrient reduction
  4. Water quality
  5. Fish and water column invertebrates
  6. Sturgeon
  7. Submerged aquatic vegetation
  8. Oysters
  9. Sea turtles
  10. Marine mammals
  11. Birds
  12. Low-light and deep seafloor communities
  13. Provide and enhance recreational opportunities

Together, these efforts will restore wildlife and habitat in the Gulf by addressing the ecosystem injuries that resulted from the Deepwater Horizon incident.

Once the plan is finally approved and the settlement is finalized, NOAA will continue to work with all of the Trustees to plan, approve, and implement restoration projects. NOAA will bring scientific  expertise and focus on addressing remedies for living marine resources — including fish, sturgeon, marine mammals, and sea turtles — as well as coastal habitats and water quality. NOAA scientists developed numerous scientific papers for the NRDA case including documentation of impacts to bottlenose dolphins, pelagic fish, sea turtles, benthic habitat and deep water corals.

The Deepwater Horizon Oil Spill Draft Programmatic Damage Assessment and Restoration Plan and Draft Programmatic Environmental Impact Statement is available for public review and comment through December 4. It is posted at and will be available at public repositories throughout the Gulf and at the meetings listed at
