Who Is Funding Research and Restoration in the Gulf of Mexico After the Deepwater Horizon Oil Spill?

This is a post by Kate Clark, Acting Chief of Staff with NOAA’s Office of Response and Restoration, and Frank Parker, Associate Director for the NOAA RESTORE Act Science Program, with NOAA’s National Centers for Coastal Ocean Science.

The Deepwater Horizon Oil Spill: Five Years Later

This is the fourth in a series of stories over the coming weeks looking at various topics related to the response, the Natural Resource Damage Assessment science, restoration efforts, and the future of the Gulf of Mexico.

When an oil spill takes place, people want to see the coasts, fish, wildlife, and recreational opportunities affected by that spill restored—so they can be as they were before, as quickly as possible. Fortunately, the Oil Pollution Act of 1990 supports this. After most major oil spills, what routinely happens is the government undertakes a Natural Resource Damage Assessment, a rigorous, scientific process of assessing environmental injuries and, with public input, identifying and implementing the appropriate amount of restoration to compensate for the injuries resulting from this spill (all paid for by those responsible for the pollution).

What is not routine in the wake of an oil spill is the groundswell of support for even more research and restoration, beyond the scope of the usual damage assessment process, to bolster the resilience of the impacted ecosystem and coastal communities. Yet that is exactly what happened after the Deepwater Horizon well blowout in 2010, which renewed a national interest in the unique environment that is the Gulf of Mexico.

In the wake of this disaster, there have been various additional investments, outside of the Natural Resource Damage Assessment process, in more broadly learning about and restoring the Gulf of Mexico. These distinct efforts to fund research and restoration in the Gulf have been sizable, but keeping track of them can be, frankly, a bit confusing.

The many organizations involved are working to ensure the Gulf’s new infusions of funding for restoration and research are well coordinated. However, keep in mind that each effort is independent of the others in funding mechanism, primary mandate, and process.

Tracking Dollars for Gulf Restoration

In one effort, announced while the Macondo well was still gushing oil, BP dedicated up to $500 million dollars to be spent over 10 years “to fund an independent research program designed to study the impact of the oil spill and its associated response on the environment and public health in the Gulf of Mexico.” This investment spawned the Gulf of Mexico Research Initiative, or GOMRI, which is governed by an independent, academic research board of 20 science, public health, and research administration experts and independent of BP’s influence.

Meanwhile, BP faced both potential criminal and civil penalties under the Clean Water Act, which regulates the discharge of pollutants into U.S. waters. When such penalties are pursued by the government for pollution events, such as an oil spill, a portion of the criminal monetary penalties are usually paid to a local environmental foundation or conservation organization to administer the funds.

Ultimately, BP agreed to a $4 billion criminal settlement in 2013, with the bulk of that money going to North American Wetlands Conservation Fund, National Fish and Wildlife Foundation, and National Academy of Sciences.

That still leaves civil penalties to be determined. Normally, civil penalties under the Clean Water Act are directed to the General Treasury.

However, Congress passed legislation calling for 80 percent of the administrative and civil penalties related to the Deepwater Horizon oil spill to be diverted directly to the Gulf of Mexico for ecological and economic restoration. This legislation, known as the RESTORE Act (Resources and Ecosystems Sustainability, Tourist Opportunities, and Revived Economies of the Gulf Coast States Act of 2012), passed on July 6, 2012.

While the full extent of BP’s civil penalties have yet to be determined, in 2013 the Department of Justice finalized a civil settlement with Transocean in the amount of $1 billion. This settlement results in more than $800 million going to the Gulf of Mexico under the RESTORE Act. As to penalties for BP, the court has currently ruled on two of the three trial phases. Based on those rulings, currently under appeal, the penalty cap for BP is $13.7 billion. A third trial phase for factors that are taken into account in establishing the penalty at or under that cap was concluded in February 2015. The court has yet to rule on the third phase of the trial, and the pending appeals have not yet been heard by the appeals court.

NOAA and Restoration in the Gulf

So where does NOAA fit into all of this? NOAA is carrying out its usual duties of working with its partners to assess injury to and restore impacted natural resources through the Natural Resource Damage Assessment process. However, NOAA also is involved in supporting broader Gulf research and resilience, which will complement the damage assessment process, in two new ways through the RESTORE Act.

First, NOAA is supporting in the RESTORE Act’s Gulf Coast Ecosystem Restoration Council, which is chaired by Commerce Secretary Penny Pritzker (NOAA sits in the Department of Commerce). Second, NOAA is leading the Gulf Coast Ecosystem Restoration Science, Observation, Monitoring, and Technology Program, or more simply, the NOAA RESTORE Act Science Program.

This program exists because we simply don’t know as much as we need to know about the Gulf of Mexico and the plants and animals that live there in order to reverse the general decline of coastal ecosystems and ensure resilience in the future.

To make sure this new science program addresses the needs of the region, NOAA, in partnership with the U.S. Fish and Wildlife Service, met with resource managers, scientists, and other Gulf of Mexico stakeholders to discuss what the focus of the program should be. We heard three key messages loud and clear:

  • Make sure the research we support is closely linked to regional resource management needs.
  • Coordinate with other science initiatives working in the region.
  • Make the results of research available quickly to those who could use them.

The NOAA RESTORE Act Science Program is already in the process of making available $2.5 million for research in the Gulf of Mexico, with more opportunities to come. (NOAA)

NOAA and the U.S. Fish and Wildlife Service have designed a science plan [PDF] for the NOAA RESTORE Act Science Program that outlines how we will make this happen.

The science plan describes the research priorities highlighted during our engagement with stakeholders and from reviewing earlier assessments of the science needed to better understand the Gulf of Mexico. These priorities will guide how the program directs its funding over the coming years.

The research priorities include improving our understanding of how much and when freshwater, sediment, and nutrients enter the coastal waters of the Gulf of Mexico and what this means for the growth of wetlands and the number of shellfish and fish in the Gulf of Mexico. Another priority is developing new techniques and technologies for measuring conditions in the Gulf to help inform resource management decisions.

Apply for Research Funding

Currently, the NOAA RESTORE Act Science Program is holding its first competition for funding, with over 100 research teams already responding. It will make $2.5 million available for researchers to review and integrate what we already know about the Gulf of Mexico and work with resource managers to develop strategies directing the program toward our ultimate goal of supporting the sustainability of the Gulf and its fisheries.

The results of this work also will help inform the direction of other science initiatives and restoration activities in the Gulf region. NOAA and the U.S. Fish and Wildlife Service will announce the winners of this funding competition in the fall of 2015.

For Alaska’s Remote Pribilof Islands, a Tale of Survival and Restoration for People and Seals

Set in the middle of Alaska’s Bering Sea, a string of five misty islands known as the Pribilof Islands possess a long, rich, and at times, dark history. A history of near extinction, survival, and restoration for both people and nature. A history involving Alaska Natives, Russians, the U.S. government and military, and seals.

It begins with the native people, known as the Unangan, who live there. They tell a story that, as they say, belongs to a place, not any one person. The story is of the hunter Iggadaagix, who first found these islands many years ago after being swept away in a storm and who wanted to bring the Unangan back there from the Aleutian Islands. When the Unangan finally did return for good, it was in the 18th century, and their lives would become intimately intertwined with those of the northern fur seals (Callorhinus ursinus). Each summer roughly half of all northern fur seals breed and give birth in the Pribilof Islands.

But these seals and their luxurious fur, along with the tale of Iggadaagix, would eventually bring about dark times for the seals, the Unangan, and the islands themselves. After hearing of Iggadaagix and searching for a new source of furs, Russian navigator Gavriil Loginovich Pribylov would land in 1786 on the islands which would eventually bear his name. He and others would bring the Unangan from the Aleutian Islands to the Pribilof’s St. George and St. Paul Islands, where they would be put to work harvesting and processing the many fur seals.

In these early years on the islands, Russian hunters so quickly decimated the fur seal population that the Russian-American Company, which held the charter for settling there, suspended hunting from 1805 to 1810. The annual limit for taking fur seals was then set at 8,000 to 10,000 pelts, allowing the population to rebound significantly.

The United States Arrives at the Islands

Fast forward to 1867, when the United States purchased Alaska, including the Pribilof Islands, from Russia for $7.2 million.

Some people considered the lucrative Pribilof Islands fur seal industry to have played a role in this purchase. In fact, this industry more than repaid the U.S. government for Alaska’s purchase price, hauling in $9,473,996 between 1870 and 1909.

The late 19th and early 20th centuries saw various U.S. military branches establish stations on the Pribilof Islands, as well as several (at times unsuccessful) attempts to control the reckless slaughter of fur seals. From 1867 until 1983, the U.S. government managed the fur seal industry on the Pribilof Islands.

In 1984, the Unangan finally were granted control of these islands, but the government had left behind a toxic legacy from commercial fur sealing and former defense sites: hazardous waste sites, dumps, contaminants, and debris.

Making Amends with the Land

This is where NOAA comes into the picture. In 1996, the Pribilof Islands Environmental Restoration Act called on NOAA to restore the environmental degradation on the Pribilof Islands. In particular, a general lack of historical accountability on the islands had led to numerous diesel fuel spills and leaks and improperly stored and disposed waste oils and antifreeze. By 1997 NOAA had removed thousands of tons of old cars, trucks, tractors, barrels, storage tanks, batteries, scrap metal, and tires from St. Paul and St. George Islands. Beginning in 2002, NOAA’s efforts transitioned to cleaning up soil contamination and assessing potential pollution in groundwater.

However, the Department of Defense has also been responsible for environmental cleanup at the Pribilof Islands. The U.S. Army occupied the islands during World War II and left behind debris and thousands of 55-gallon drums, which were empty by 1985 but had previously contained petroleum, oils, and lubricants, which could have leaked into the soil.

By 2008, NOAA’s Office of Response and Restoration had fulfilled its responsibilities for cleaning up the contamination on the Pribilof Islands, closing a dark chapter for this remote and diverse area of the world and hopefully continuing the healing process for the Unangan and fur seals who still call these islands their home.

How NOAA Uses Coral Nurseries to Restore Damaged Reefs

Staghorn coral fragments hanging on an underwater tree structure of PVC pipes.

NOAA uses coral nurseries to help corals recover after traumatic events, such as a ship grounding. Hung on a tree structure, the staghorn coral shown here will have a better chance of surviving and being transplanted back onto a reef. (NOAA)

The cringe-inducing sound of a ship crushing its way onto a coral reef is often the beginning of the story. But, thanks to NOAA’s efforts, it is not usually the end. After most ship groundings on reefs, hundreds to thousands of small coral fragments may litter the ocean floor, where they would likely perish rolling around or buried under piles of rubble. However, by bringing these fragments into coral nurseries, we give them the opportunity to recover.

In the waters around Florida, Puerto Rico, and the U.S. Virgin Islands, NOAA works with a number of partners in various capacities to maintain 27 coral nurseries. These underwater safe havens serve a dual function. Not only do they provide a stable environment for injured corals to recuperate, but they also produce thousands of healthy young corals, ready to be transplanted into previously devastated areas.

Checking into the Nursery

When they enter coral nurseries, bits of coral typically measure about four inches long. They may come from the scene of a ship grounding or have been knocked loose from the seafloor after a powerful storm. Occasionally and with proper permission, they have been donated from healthy coral colonies to help stock nurseries. These donor corals typically heal within a few weeks. In fact, staghorn and elkhorn coral, threatened species which do well in nurseries, reproduce predominantly via small branches breaking off and reattaching somewhere new.

In the majority of nurseries, coral fragments are hung like clothes on a clothesline or ornaments on trees made of PVC pipes. Floating freely in the water, the corals receive better water circulation, avoid being attacked by predators such as fireworms or snails, and generally survive at a higher rate.

After we have established a coral nursery, divers may visit as little as a few times per year or as often as once per month if they need to keep algae from building up on the corals and infrastructure. “It helps if there is a good fish population in the area to clean the nurseries for you,” notes Sean Griffin, a coral reef restoration ecologist with NOAA.

Injured corals generally take at least a couple months to recover in the nurseries. After a year in the nursery, we can transplant the original staghorn or elkhorn colonies or cut multiple small fragments from them, which we then use either to expand the nursery or transplant them to degraded areas.


One of the fastest growing species, staghorn coral can grow up to eight inches in a year while elkhorn can grow four inches. We are still investigating the best ways to cultivate some of the slower growing species, such as boulder star coral and lobed star coral.

Growing up to Their Potential

In 2014, we placed hundreds of coral fragments from four new groundings into nurseries in Puerto Rico and the U.S. Virgin Islands. This represents only a fraction of this restoration technique’s potential.

After the tanker Margara ran aground on coral reefs in Puerto Rico in 2006, NOAA divers rescued 11,000 salvageable pieces of broken coral, which were reattached at the grounding site and established a nursery nearby using 100 fragments from the grounding. That nursery now has 2,000 corals in it. Each year, 1,600 of them are transplanted back onto the seafloor. The 400 remaining corals are broken into smaller fragments to restock the nursery. We continue to grow healthy corals in this nursery and then either transplant them back to the area affected by the grounded ship, help restore other degraded reefs, or use some of them to start the process over for another year.

Nurseries in Florida, Puerto Rico, and the U.S. Virgin Islands currently hold about 50,000 corals. Those same nurseries generate another 50,000 corals which we transplant onto restoration sites each year. Sometimes we are able to use these nurseries proactively to protect and preserve corals at risk. In the fall of 2014, a NOAA team worked with the University of Miami to rescue more than 200 threatened staghorn coral colonies being affected by excessive sediment in the waters off of Miami, Florida. The sedimentation was caused by a dredging project to expand the Port of Miami entrance channel.

We relocated these colonies to the coral nurseries off Key Biscayne run by our partners at the University of Miami. The corals were used to create over 1,000 four-inch-long fragments in the nursery. There, they will be allowed to recover until dredge operations finish at the Port of Miami and sedimentation issues are no longer a concern. The corals then can either be transplanted back onto the reef where they originated or used as brood stock in the nursery to propagate more corals for future restoration.

When the Dynamics of an Oil Spill Shut Down a Nuclear Power Plant

Yellow containment boom floats on a river next to a nuclear power plant.

Precautionary containment boom is visible around the water intake system at the Salem Nuclear Generating Station in New Jersey on December 6, 2004. The nuclear plant was shut down for 11 days to prevent the heavy, submerged oil from the Athos spill from clogging the water intakes. (NOAA)

“I’ve never reopened a nuclear power plant,” thought NOAA’s Ed Levine. Despite that, Levine knew it was his job to get the right information to the people who ultimately would make that decision. This was his role as a NOAA Scientific Support Coordinator during oil spills. However, most major oil spills do not affect nuclear power plants. This wintry day in 2004 was an exception.

Forty miles north of the Salem Nuclear Generating Station in New Jersey, an oil tanker called the Athos I had struck an object hidden beneath the Delaware River. As it was preparing to dock at the CITGO refinery near Philadelphia on November 26, the ship began tilting to one side, the engine shut down, and oil started gushing out.

“Not your typical oil spill,” later reflected Jonathan Sarubbi, who served as U.S. Coast Guard Captain of the Port and led the federal response during this incident. Not only did no one immediately know what the ship had hit—or where that object was located in the river channel—but the Athos, now sitting too low in the water to reach the dock, was stuck where it was. And it was still leaking its cargo of heavy Venezuelan crude oil.

Capt. Sarubbi ordered vessel traffic through this busy East Coast shipping channel to stop until the object the Athos hit could be found. Little did Capt. Sarubbi, Levine, and the other responders know that even more challenges would be in store beneath the water and down the river.

Getting Mixed up

Most oils, most of the time, float on the surface of water. This was precisely what responders expected the oil coming out of the Athos to do. But within a couple days of the spill, they realized that was not the case. This oil was a little on the heavier side. As it shot out of the ship’s punctured bottom, some of the oil mixed with sediment from the river bottom. It didn’t have far to go; thanks to an extremely low tide pulling the river out to sea, the Athos was passing a mere 18 inches above the bottom of the river when it sprung a leak.

Now mixed with sediment, some of the spilled oil became as dense as or denser than water. Instead of rising to the river surface, it sank to the bottom or drifted in the water column. Even some of the oil that floated became mixed with sediment along the shoreline, later sinking below the surface. For the oil suspended in the water, the turbulence of the Delaware River kept it moving with the currents increasingly toward the Salem nuclear plant, perched on the river’s edge.

NOAA’s oil spill trajectory model GNOME forecasts the spread of oil by assuming the oil is floating on the water’s surface. Normally, our oceanographers can verify how well the forecasts are doing by calibrating the model against twice-a-day aerial surveys of the oil’s movement. The trouble with oil that does not float is that it is harder to see, especially in the murky waters of the Delaware River.

Responders were forced to improvise. To track oil underwater, they created new sampling methods, one of which involved dropping weighted ropes into the water column at various points along the river. The ropes were lined with what looked like cheerleader pom-poms made of oil-attracting plastic strips that would pick up oil as it passed by.

Nuclear Ambitions

Nuclear plants like the Salem facility rely on a steady flow of freshwater to cool their reactors. A thin layer of floating oil was nearing the plant by December 1, 2004, with predictions that the heavier, submerged oil would not be far behind. By December 3, small, sticky bits of oil began showing up in the screens on the plant’s cooling water intakes. To keep them from becoming clogged, the plant decided to shut down its two nuclear reactors the next day. That was when NOAA’s Ed Levine was tasked with figuring out when the significant threats due to the oil had passed.

Eleven days later, the Salem nuclear plant operators, the State of New Jersey, and the Nuclear Regulatory Commission allowed the plant to restart. A combination of our modeling and new sampling methods for detecting underwater oil had shown a clear and significant drop in the amount of oil around the plant. Closing this major electric generating facility cost $33.1 million out of more than $162 million in claims paid to parties affected by the Athos spill. But through our innovative modeling and sampling, we were able to reduce the time the plant was offline, minimizing the disruption to the power grid and reducing the economic loss.

Levine recalled this as an “eye-opening” experience, one yielding a number of lessons for working with nuclear power plants should an oil spill threaten one in the future. To learn more about the Athos oil spill, from response to restoration, visit response.restoration.noaa.gov/athos.

Carrying on a Nearly Fifty Year Tradition, Scientists Examine the Intersection of Pollution and Marine Life

As reliably as the tides, each month biologist Donald J. Reish would wash over the library at California State University, Long Beach, armed with stacks of 3×5 index cards. On these cards, Reish meticulously recorded every scientific study published that month on pollution’s effects on marine life. When he began this ritual in 1967, this did not amount to very many studies.

“There was essentially none at the time,” says Reish, who helped pioneer the study of pollution’s impacts on marine environments in the 1950s.

Nevertheless, after a year of collecting as much as he could find in scientific journals, he would mail the index cards with their handwritten notes to a volunteer crew that often included his former graduate students, including Alan Mearns, now an ecologist with NOAA’s Office of Response and Restoration. Like a wave, they would return to the library to read, review, and send summaries of these studies back to Reish. At his typewriter, he would compile the individual summaries into one comprehensive list, an “in case you missed it” for scientists interested in this emerging field of study. This compilation would then be published in a scientific journal itself.

By the early 2000s, Reish handed off leadership of this annual effort to Mearns, an early recruit to the project. Today, Mearns continues the nearly 50 year tradition of reviewing the state of marine pollution science and publishing it in the journal Water Environment Research. Their 2014 review, “Effects of Pollution on Marine Organisms,” comes together a little differently than in the 1960s and 70s—and covers issues that have changed with the years as well.

Signs of the Times

Man and woman at a desk covered with scientific papers.

NOAA Office of Response and Restoration biologists Alan Mearns and Nicolle Rutherford tackle another year’s worth of scientific studies, part of an effort begun in 1967. (NOAA)

For starters, vastly more studies are being published on marine pollution and its environmental effects. For this year’s publication, Mearns and his six co-authors, who include Reish and NOAA scientists Nicolle Rutherford and Courtney Arthur, reviewed 341 scientific papers which they pulled from a larger pool of nearly 1,000 studies.

The days of having to physically visit a library each month to read the scientific journals are also over. Instead, Mearns can wait until the end of the year to scour online scientific search engines. Emails replace the handwritten 3×5 index cards. And fortunately, typewriters are no longer involved.

The technology the reviewers are using isn’t the only thing to change with the years. In the early days, the major contaminants of concern were heavy metals, such as copper, which were turning up in the bodies of fish and invertebrates. Around the 1970s, the negative effects of the insecticide DDT found national attention, thanks to the efforts of biologist Rachel Carson in her seminal book Silent Spring.

Today, Mearns and Reish see the focus of research shifting to other, often more complicated pollutants, such as nanomaterials, which can be any of a number of materials roughly 100,000 times smaller than the width of a human hair. On one hand, nanotechnology is helping scientists decipher the effects of some pollutants, while, on the other, nanomaterials, such as those found in cosmetics, show potentially serious effects on some marine life including mussels.

Another major trend has been the evolution of the ways scientists evaluate the effects of pollutants on marine life. Researchers in the United States and Western Europe used to study the toxicity of a pollutant by increasing the amount animals are exposed to until half the study animals died. In the 1990s, researchers began exploring pollutants’ finer physiological effects. How does exposure to X pollutant affect, for example, a fish’s ability to feed or reproduce?

Nowadays, the focus is even more refined, zeroing in on the molecular scale to discern how pollutants affect an animal’s genetic material, its DNA. How does the presence of oil change whether certain genes in a fish’s liver are turned on or off? What does that mean for the fish?

A Year of Pollution in Review

With three Office of Response and Restoration scientists working on this effort, it unsurprisingly features a lot on oil spills and marine debris, two areas of our expertise.

Of particular interest to Mearns and Rutherford, as oil spill biologists, are the studies of biodegradation of oil in the ocean, specifically, how microbes break down and eat components of oil, especially the toxic polycyclic aromatic hydrocarbons (PAHs). Scientists are examining collections of genes in such microbes and determining which ones produce enzymes that degrade PAHs.

“That field has really exploded,” says Mearns. “It’s just amazing what they’re finding once they use genomics and other tools to go into [undersea oil spill] plumes and see what these critters are doing and eating.”

Marine debris research in 2013 focused on the effects of eating, hitchhiking on, or becoming entangled in debris. Studies examined the resulting impacts on marine life, including sea birds, fish, crabs, turtles, marine mammals, shellfish, and even microbes. The types of debris that came up again and again were abandoned fishing gear and plastic fragments. In addition, quite a bit of research attempted to fill in gaps in understanding of how plastic debris might take up and then leach out potentially dangerous chemicals.

Attitude Adjustment

A group of men and women stand around Don Reish.

Reish often relied on his former graduate students, including NOAA’s Alan Mearns, to help review the many studies on marine pollution’s effects each year. Shown here in 2004, Reish (seventh from left) is surrounded by a few of his former students who gathered to honor him at the Southern California Academy of Sciences Annual Meeting. Mearns is fifth from left and another contributer, Phil Oshida of the U.S. Environmental Protection Agency, stands between and behind Mearns and Reish. (Alan Mearns)

Perhaps the most significant change over the decades has been a change in attitudes. Reish recalled a presentation he gave at a scientific meeting in 1955. He was discussing his study of how marine worms known as polychaetes changed where they lived based on the effects of pollution in southern California. Afterward, he sat down next to a professor from another college, whose response to his presentation was, “Don, why don’t you go do something important?”

In 2014 attitudes generally skew to the other end of the spectrum when it comes to understanding human impacts on our world and how intertwined these impacts often are with human well-being.

And while there is a lot of bad news about these impacts, Mearns and Reish have seen some bright spots as well. Scientists are starting to observe slow declines in the presence of toxic chemicals, such as DDT from insecticides and PCBs from industrial manufacturing, which last a long time in the environment and build up in the bodies of living things, such as the fish humans like to catch and eat.

The end of the year is approaching and, reliably, Mearns and his colleagues are again preparing to scan hundreds of studies for their annual review of the scientific literature. Reflecting on this effort, Mearns points out another benefit of bringing together such a wide array of research disciplines. It encourages him to cross traditional boundaries of scientific study, enriching his work in the process.

“For me, it inspires out-of-the-box thinking,” says Mearns. “I’ll be looking at wastewater discharge impacts and I’ll spot something that I think is relevant to oil spill studies…We can find out things from these other fields and apply them to our own.”

The Earth Is Blue and We’d Like to Keep It That Way

Often, you have to leave a place to gain some perspective.

Sometimes, that means going all the way to outer space.

When humans ventured away from this planet for the first time, we came to the stunning realization that Earth is blue. A planet covered in sea-to-shining-sea blue. And increasingly, we began to worry about protecting it. With the creation of the National Marine Sanctuaries system in 1972, a very special form of that protection began to be extended to miles of ocean in the United States. Today, that protection takes the form of 14 marine protected areas encompassing more than 170,000 square miles of marine and Great Lakes waters.

Starting October 23, 2014, NOAA’s Office of National Marine Sanctuaries is celebrating this simple, yet profound realization about our planet—that Earth is Blue—on their social media accounts. You can follow along on Facebook, Twitter, YouTube, and now their brand-new Instagram account @NOAAsanctuaries. Each day, you’ll see an array of striking photos (plus weekly videos) showing off NOAA’s—and more importantly, your—National Marine Sanctuaries, in all of their glory. Share your own photos and videos from the sanctuaries with the hashtag #earthisblue and find regular updates at sanctuaries.noaa.gov/earthisblue.html.

You can kick things off with this video:

Marine sanctuaries are important places which help protect everything from humpback whales and lush kelp forests to deep-sea canyons and World War II shipwrecks. But sometimes the sanctuaries themselves need some extra protection and even restoration. In fact, one of the first marine sanctuaries, the Channel Islands National Marine Sanctuary off of southern California, was created to protect waters once imperiled by a massive oil spill which helped inspire the creation of the sanctuary system in the first place.

To minimize damage to the coastline and marine habitat, federal agencies removed the Japanese dock that turned up on the Washington coast in late 2012. In addition to being located within a designated wilderness portion of Olympic National Park, the dock was also within NOAA’s Olympic Coast National Marine Sanctuary and adjacent to the Washington Islands National Wildlife Refuge Complex. (National Park Service)

At times NOAA’s Office of Response and Restoration is called to this role when threats such as an oil spill, grounded ship, or even huge, floating dock endanger the marine sanctuaries and their incredible natural and cultural resources.

Olympic Coast National Marine Sanctuary

In March 2013, we worked with a variety of partners, including others in NOAA, to remove a 185-ton, 65-foot Japanese floating dock from the shores of Washington. This dock was swept out to sea from Misawa, Japan, during the 2011 tsunami and once it was sighted off the Washington coast in December 2012, our oceanographers helped model where it would wash up.

Built out of plastic foam, concrete, and steel, this structure was pretty beat up by the time it ended up inside NOAA’s Olympic Coast National Marine Sanctuary and a designated wilderness portion of Olympic National Park. A threat to the environment, visitors, and wildlife before we removed it, its foam was starting to escape to the surrounding beach and waters, where it could have been eaten by the marine sanctuary’s whales, seals, birds, and fish.

Florida Keys National Marine Sanctuary

In an effort to protect the vibrant marine life of the Florida Keys National Marine Sanctuary, NOAA’s Restoration Center began clearing away illegal lobster fishing devices known as “casitas” in June 2014. The project is funded by a criminal case against a commercial diver who for years used casitas to poach spiny lobsters from the sanctuary’s seafloor. Constructed from materials such as metal sheets, cinder blocks, and lumber, these unstable structures not only allow poachers to illegally harvest huge numbers of spiny lobsters but they also damage the seafloor when shifted around during storms.

Also in the Florida Keys National Marine Sanctuary, our office and several partners ran through what it would be like to respond to an oil spill in the sanctuary waters. In April 2005, we participated in Safe Sanctuaries 2005, an oil spill training exercise that tested the capabilities of several NOAA programs, as well as the U.S. Coast Guard. The drill scenario involved a hypothetical grounding at Elbow Reef, off Key Largo, of an 800-foot cargo vessel carrying 270,000 gallons of fuel. In the scenario, the grounding injured coral reef habitat and submerged historical artifacts, and an oil spill threatened other resources. Watch a video of the activities conducted during the drill.

Papahānaumokuākea Marine National Monument

Even hundreds of miles from the main cluster of Hawaiian islands, the Papahānaumokuākea Marine National Monument does not escape the reach of humans. Each year roughly 50 tons of old fishing nets, plastics, and other marine debris wash up on the sensitive coral reefs of the marine monument. Each year for nearly 20 years, NOAA divers and scientists venture out there to remove the debris.

This year, the NOAA Marine Debris Program’s Dianna Parker and Kyle Koyanagi are documenting the effort aboard the NOAA Ship Oscar Elton Sette. You can learn more about and keep up with this expedition on the NOAA Marine Debris Program website.

Out of Sandy, Lessons in Helping Coastal Marshes Recover from Storms

Boats capsized in a sea of grass. Tall trees and power lines toppled over. A dark ring of oil rimming marsh grasses. This was the scene greeting NOAA’s Simeon Hahn and Carl Alderson a few days after Sandy’s floodwaters had pulled back from New Jersey in the fall of 2012.

They were surveying the extent of an oil spill in Woodbridge Creek, which is home to a NOAA restoration project and feeds into the Arthur Kill, a waterway separating New Jersey from New York’s Staten Island. When the massive storm known as Sandy passed through the area, its flooding lifted up a large oil storage tank at the Motiva Refinery in Sewaren, New Jersey. After the floodwaters set the tank back down, it caused roughly 336,000 gallons of diesel fuel to leak into the creek and surrounding wetlands.

That day, the NOAA team was there with Motiva and the New Jersey Department of Environmental Protection (DEP) to begin what can be a long and litigious process of determining environmental impacts, damages, and required restoration—the Natural Resource Damage Assessment process.

In this case, however, not only did the group reach a cooperative agreement—in less than six months—on a restoration plan for the oiled wetlands, but at another wetland affected by Sandy, NOAA gained insight into designing restoration projects better able to withstand the next big storm.

Cleaning up the Mess After a Hurricane

Hurricanes and other large storms cause a surprising number of oil and hazardous chemical spills along the coast. After Sandy hit New York and New Jersey, the U.S. Coast Guard began receiving reports of petroleum products, biodiesel, and other chemicals leaking into coastal waters from damaged refineries, breached petroleum storage tanks, and sunken and stranded vessels. The ruptured tank at the Motiva Refinery was just one of several oil spills after the storm, but the approach in the wake of the spill is what set it apart from many other oil spills.

“Early on we decided that we would work together,” reflected Hahn, Regional Resource Coordinator for NOAA’s Office of Response and Restoration. “There was a focus on doing the restoration rather than doing lengthy studies to quantify the injury.”

This approach was possible because Motiva agreed to pursue a cooperative Natural Resource Damage Assessment with New Jersey as the lead and with support from NOAA. This meant, for example, that up front, the company agreed to provide funding for assessing the environmental impacts and implementing the needed restoration, and agreed on and shared the data necessary to determine those impacts. This cooperative process resulted in a timely and cost-effective resolution, which allowed New Jersey and NOAA to transition to the restoration phase.

Reaching Restoration

Because of the early agreement with Motiva, NOAA and New Jersey DEP did not conduct exhaustive new studies detailing specific harm to these particular tidal wetlands. Instead, they turned to the wealth of data from the oil spill response and existing data from the Arthur Kill to make an accurate assessment of the oil’s impacts.

From their shoreline, aerial, and boat surveys, they knew that the marsh itself had a bathtub ring of oil around the edge, affecting marsh grasses such as Spartina. No oiled wildlife turned up. However, the storm’s immediate impacts made it difficult to take water and sediment samples or directly examine potential effects to fish. Fortunately, the assessment team was able to use a lot of data from a nearby past oil spill and damage assessment in the Arthur Kill. In addition, they could rely on both general scientific research on oil spill toxicology and maps from the response team detailing the areas most heavily oiled.

Together, this created a picture of the environmental injuries the oil spill caused to Woodbridge Creek. Next, NOAA economists used the habitat equivalency analysis approach to calculate the amount of restoration needed to make up for these injuries: 1.23 acres of tidal wetlands. They then extrapolated how much it will cost to do this restoration based on seven restoration projects within a 50 mile radius, coming to $380,000 per acre. As a result, NOAA and New Jersey agreed that Motiva needed to provide $469,000 for saltwater marsh restoration and an additional $100,000 for monitoring, on top of Motiva’s cleanup costs for the spill itself.

To use this relatively small amount of money most efficiently, New Jersey DEP, as the lead agency, is planning to combine it with another, larger restoration project already in the works. While still negotiating which project that will be, the team has been eyeing a high-profile, 80-acre marsh restoration project practically in the shadow of the Statue of Liberty. Meanwhile, the monitoring project will take place upstream from the site of the Motiva oil spill at the 67-acre Woodbridge Creek Marsh, which received light to moderate oiling. NOAA already has data on the state of the animals and plants at this previously established restoration site, which will provide a rare comparison for before and after the oil spill.

Creating More Resilient Coasts

A storm as damaging as Sandy highlights the need for restoring wetlands. These natural buffers offer protection for human infrastructure, absorbing storm surge and shielding shorelines from wind and waves. Yet natural resource managers are still learning how to replicate nature’s designs, especially in urban areas where river channels often have been straightened and adjoining wetlands filled and replaced with shorelines armored by concrete riprap.

To the south in Philadelphia, Sandy contributed to significant erosion at a restored tidal marsh and shoreline at Lardner’s Point Park, located on the Delaware River. This storm revealed that shoreline restoration techniques which dampen wave energy before it hits the shore would help protect restored habitat and reduce erosion and scouring.

Out of this destructive storm, NOAA and our partners are trying to learn as much as possible—both about how to reach the restoration phase even more efficiently and how to make those restoration projects even more resilient. The wide range of coastal threats is not going away, but we at NOAA can help our communities and environment bounce back when they do show up on our shores.
