This is a post by Sarah Opfer, NOAA Marine Debris Program Great Lakes Regional Coordinator.
Plastic debris in the form of fragments, bottle caps, food packaging, and smoking products are commonly found on Great Lake beaches. Here, marine debris has washed up at Maumee Bay State Park on the shores of Lake Erie. (NOAA Marine Debris Program)
The “Great Pacific Garbage Patch“—a purported island of trash twice the size of Texas floating in the Pacific Ocean—receives a lot of media attention. Recent reports suggest that a similar garbage patch may be developing in the Great Lakes as well.
However, based on research we know that the name “garbage patch” is misleading and that there is no island of trash forming in the middle of the ocean. We also know that there is no blanket of marine trash that is visible using current satellite or aerial photography.
Plastic debris is found in Great Lake waters as well. This debris was pulled from a Lake Erie marina during a cleanup. (NOAA Marine Debris Program)
Yet, there are places in the ocean where currents bring together lots and lots of floatable materials, such as plastics and other trash. While the types of litter gathering in these areas can vary greatly, from derelict fishing nets to balloons, the kind that is capturing the most attention right now are microplastics. These are small bits of plastic often not immediately evident to the naked eye.
While we know about the so-called “garbage patches” in the Pacific Ocean, could there be a similar phenomenon in other parts of the world, including the Great Lakes? Recent research on the distribution of plastics in the Great Lakes has people now asking that very question.
The Great Lakes are no mere group of puddles. They contain nearly 20% of the world’s surface freshwater and have a coastline longer than the East Coast of the United States. Within the Great Lakes system, water flows from Lake Superior and Lake Michigan, the lakes furthest west and highest in elevation, east into Lake Huron. From there, it travels through Lake St. Clair and the Detroit River into Lake Erie. Then, some 6 million cubic feet of water pass over Niagara Falls each minute and into Lake Ontario before flowing through the St. Lawrence River and into the Atlantic Ocean.

This water flow influences circulation patterns within and between each of the lakes. Currents within the Great Lakes also are powered by wind, waves, energy from the sun, water density differences, the shape of the lakebed, and the shoreline. These circulation currents have the tendency to create aggregations of garbage and debris in certain areas, just like in the oceans. But, just as in the Pacific Ocean, this doesn’t mean the Great Lakes have floating trash islands either.
In an effort to better identify and understand how plastic debris is spread throughout the Great Lakes, researchers at the University of Waterloo in Canada have partnered with COM DEV on an exploratory research project. COM DEV is a designer and manufacturer of space and remote sensing technology. Researchers are working with this industry partner to develop and test the ability of different remote sensors to detect plastics in the Great Lakes.
If they find the task is feasible and the trial runs prove to be effective, this work could be applied beyond the Great Lakes and across the United States. The NOAA Marine Debris Program, part of the Office of Response and Restoration, is engaged with and following the project. We plan to participate in the next steps of this promising effort. You can learn more about the project and a related workshop on plastic pollution in the Great Lakes.

Here, we take a peek into the world of science policy (and the budgets that make it possible) as we hear from Dave Westerholm, director of NOAA’s Office of Response and Restoration, about what we can expect as a starting point for this office in the next fiscal year.

The White House recently released the President’s Budget for Fiscal Year 2014. This budget offers several exciting opportunities for research, development, and growth in response and restoration activities at NOAA. The budget contains close to $4 million in increases for the Office of Response and Restoration (OR&R).
While meeting the needs of those critical issues, we have continued to support the ongoing response and damage assessment for the Deepwater Horizon/BP oil spill, looked forward to address emerging challenges in the U.S. Arctic by launching an Environmental Response Management Application (ERMA) online mapping tool for the Arctic region and contributed our expertise to interagency planning and preparedness in support of ongoing energy exploration in the Arctic.
I am eager to show you what OR&R can do with the latest budget from the President that will build upon our recent achievements:
The fiscal year 2014 budget proposes a $2 million increase for Natural Resource Damage Assessment to increase technical, strategic, and legal support so we can more quickly move more oil spill and hazardous waste site cases toward settlement and support the restoration process. We anticipate that this increase will more than pay for itself in settlement funds recovered from responsible parties and deliver significant return on investment for the American public.
There is an increase of $1 million for the NOAA Marine Debris Program to fund a variety of programs and efforts to reduce and prevent the impacts of marine debris.This includes funding for:
research programs and academic institutions with demonstrated expertise in the economic impacts of marine debris.
alternatives to fishing gear that pose potential marine threats.
enhanced tracking, recovery, and identification of lost and discarded fishing gear.
efforts to reduce the amount of baseline debris from ocean and non-ocean based sources.
Additionally, the Marine Debris Program’s regional marine debris coordination program will receive a funding increase to enhance regional efforts and develop response plans for states in the Northeast, Southeast, and Gulf of Mexico as described under the Marine Debris Act. These plans will help federal, state, and local authorities plan and prepare for the next major marine debris cleanup event, for example, a hurricane.
This budget also proposes funding increases for emergency response preparedness in the Arctic and Gulf of Mexico and for our innovative ERMA tool to transition to a cloud computing platform. These funds will allow OR&R to improve our services through participation in more regional response exercises with governmental and private partners and enhance scientific support for the Arctic through increased direct engagement with Arctic communities.
I invite you to review the NOAA Fiscal Year 2014 Budget Summary [PDF] for more detailed information on all of NOAA’s proposed activities in the President’s budget.
Each budgetary increase provides a significant opportunity to build NOAA’s capacity to assess future oil and chemical spill impacts, plan for increased maritime activity in the Arctic, and expand our scientific and tactical capabilities using state-of-the-art information management. The budget also will help NOAA to develop capabilities that will lead to more effective strategies to prevent and mitigate the effects of marine debris. I hope to work with our office’s many partners and supporters in the coming months to ensure OR&R’s capacity will continue to meet the rising tide of ocean and coastal challenges to protect lives, property, and the environment and to keep commerce moving.

With Memorial Day approaching and summer weather returning, folks in the northeast will once again be flocking to the shore, as they have for generations. This summer season is the first since Hurricane Sandy hit the region in late October of 2012, with devastating effects to beaches from Connecticut to Virginia. Much of the damage has been repaired and many visitors likely will find their favorite beaches as enjoyable as ever, but there is much work remaining to do.
Headed for Calmer Shores

LTJG Alice Drury of OR&R is in the middle of the group. (U.S. Coast Guard)
The NOAA Office of Response and Restoration (OR&R) responded immediately in the wake of the massive storm. OR&R’s Emergency Response Division provided scientific support to the U.S. Coast Guard to contain a major diesel spill at the Motiva Refinery in Sewarren, N.J., next to New York’s Staten Island and Raritan Bay. We also provided support for the many smaller petroleum product spills in northern New Jersey and southern New York. Aerial and ground surveys helped identify and prioritize the cleanup of pollution sources from boats, displaced hazardous material containers, and other debris.
OR&R was on scene working with other state and federal agencies to lead a preliminary assessment of natural resource impacts from the oil spills for possible Natural Resource Damage Assessment claims and restoration. In addition, the Coast Guard and other responders used OR&R’s collaborative online mapping tool, Environmental Response Management Application (ERMA®) for the Atlantic Coast, as the “common operational picture,” that is, the official “big picture” tool for coordinating pollution response activities.

In the aftermath of Hurricane Sandy, Atlantic ERMA served as the common operational picture for the Hurricane Sandy pollution response. It aided the NOAA Scientific Support Coordinators (our pollution first responders), U.S. Coast Guard, and U.S. Environmental Protection Agency in the removal and cleanup of identified pollution sources andthreats.
Atlantic ERMA integrated these response efforts with environmental data (like locations of sensitive habitat) to give responders a better idea of how to deal with pollution threats while minimizing environmental damages.
As the common operational picture, ERMA provided a single platform for responders to view all of the storm-related data and imagery as well as various cleanup efforts by the states and other federal agencies. Our team of Geographic Information Systems (GIS) specialists working on ERMA also helped provide data management support in tracking the progress made by the pollution response field teams.
Making it Safe to Get Back in the Water
In the Hurricane Sandy Relief Bill, Congress provided the NOAA Marine Debris Program with funds to address marine debris issues resulting from Sandy. In addition, funds were allocated to OR&R’s Emergency Response Division to update our Environmental Sensitivity Index maps on the east coast, with particular emphasis on areas affected by Hurricane Sandy and other coastal storms over the past several years. These maps identify coastal shorelines, wildlife, and habitat that may be especially vulnerable to an oil spill and also include the resources people use, such as a fishery or recreational beach.

Marine debris can be found in concentrations across the impacted region both on the shoreline and below the water surface. These items pose potential hazards to navigation, commercial fishing grounds, and sensitive ecosystems.
We are using Atlantic ERMA to provide mapping support and tools to show aerial imagery, debris dispersion models, and identified marine debris locations supplied by stakeholders. Our mapping support also helps with the planning efforts for debris cleanup.
A combination of aerial, underwater, and shoreline surveys are necessary to assess the quantity and location of marine debris in the impacted coastal areas. These assessments will allow NOAA to estimate the debris impacts to economies and ecosystems, identify priority items for removal, support limited removal efforts, and help bring our northeastern shores back to a sunnier state.
The San Miguel Natural Reserve in Puerto Rico is made up of 422 acres of protected coastal lands and was acquired to compensate the public after a barge ran aground, damaging coral and spilling oil near San Juan in 1994. (NOAA)
Spending time at the beach is reported to be one of America’s favorite vacation memories [PDF]. So, when our coasts become polluted, the effects can seem both traumatic and personal: damaged habitats; dirtied water; injured birds, fish, wildlife, and plants; and blemished places where we boat, fish, and play. But thanks to NOAA’s Office of Response and Restoration, we help reverse these impacts—whether from an oil spill, toxic chemicals, or marine debris—through our scientific solutions for protecting and restoring our favorite natural places.
To celebrate National Travel and Tourism Week (May 4-12), we have gathered a few examples of the places you can visit that our office is helping protect and restore.
San Juan, Puerto Rico
Sandy beaches, swaying palm trees, and turquoise waters—Puerto Rico is the quintessential tropical vacation destination. Besides surfing, snorkeling, and swimming at its more than 270 miles of beaches, this Caribbean island offers jungle adventures, resort relaxation, and Spanish colonial history. But on an island only 110 miles long and 40 miles wide, the ocean is never far away.
On January 7, 1994, just before dawn, a barge the length of a football field plowed into the picturesque surf near San Juan, Puerto Rico. When it grounded, the Tank Barge Morris J. Berman damaged coral reefs and spilled 800,000 gallons of a thick, black fuel oil into the deep blue waters off Puerto Rico’s Atlantic coast. After the grounding, the barge continued to leak, spilling more than 85,000 gallons of oily water as it was towed offshore and scuttled (intentionally sunk) 23 miles northeast of San Juan. About 169 miles of ocean and bay shorelines were affected by the spilled oil, disrupting beachgoers, boaters, and sportfishers for up to three months in some areas. The oil also crept onto the shoreline of several historic sites, including San Juan National Historic Site, a National Park and UNESCO World Heritage Site. And in the end, nearly 111,000 square feet of coral reef were damaged from the grounded barge and subsequent response measures.

NOAA’s Office of Response and Restoration was involved in a variety of activities from the start: forecasting the oil’s spread, performing aerial surveys of the spill, assessing impacted shorelines, and advising the Coast Guard on potential environmental impacts of sinking the leaking barge. Our involvement carried beyond spill cleanup and extended to evaluating and determining how the spill injured natural resources, which included people’s use of them. To compensate the public for the spill’s impacts, we helped implement a suite of projects focused on restoring damaged reefs, recreational beach use, and lost tourism at San Juan National Historic Site.
To begin restoring the coral ecosystems, NOAA and our partners built the Condado Coral Reef Trail, comprised of three underwater educational trails adjacent to a public beach. Along each trail, we placed ten pre-made artificial cement reefs, intended to establish similar reef habitat to that damaged by the barge grounding. This project wrapped up in the fall of 2008 and provides an incredible first-hand opportunity to learn about coral reefs and restoring natural resources in Puerto Rico.
San Francisco, California
According to the San Francisco Travel Association, more than 16.5 million visitors traveled to San Francisco, Calif., in 2012. Known as the “City by the Bay,” San Francisco is closely connected to its maritime heritage and marine resources. Fisherman’s Wharf is a popular northern waterfront area home to the city’s fleet of fishing boats, many of whose owners have been fishing there for three generations and bringing in the fresh seafood both locals and tourists savor. The Golden Gate Bridge, the city’s most iconic bridge, links San Francisco Bay to the Pacific Ocean and its bustling maritime commerce.

But on the typically foggy morning of November 7, 2007, the 900-foot cargo ship Cosco Busan slammed against the San Francisco-Oakland Bay Bridge and caused one of the largest oil spills in the bay’s history. Scraping a 100-foot-long gash into the vessel’s side, the crash released 53,000 gallons of a thick fuel oil, which quickly dispersed into the surrounding waters and onto sensitive coastline both in the bay and along the outer coast. Similar to our efforts after the barge grounding in Puerto Rico, NOAA’s Office of Response and Restoration provided forecasts of the oil’s path, aerial oil surveys, oiled shoreline assessment, and other scientific support for the spill response.

NOAA and our partners determined that, as a result, the incident oiled more than 3,300 acres of shoreline habitat, killed an estimated 6,849 birds and thousands of herring, and lost an estimated 1,079,900 possible recreational days for individuals. In addition, it temporarily closed a dozen urban beaches [PDF], and even shoreline along Alcatraz Island, a National Park and home to the infamous prison, suffered heavy oiling after the spill. More than $30 million was awarded from the company responsible to restore injured birds, fish, eelgrass vegetation, habitat, and lost outdoor recreation.
The bulk of these funds (tentatively $18.8 million) is allocated for a slew of improvements benefiting Bay Area recreational activities, such as picnicking, hiking, surfing, kiteboarding, fishing, and boating. These projects will take place in the Golden Gate National Recreation Area, Point Reyes National Seashore, and other areas of the East Bay and San Mateo and Marin County. They range from improving beach and fishing access and enhancing trails and shorelines to repairing waterfront park infrastructure and supporting lifeguard and educational programs. Restoration is expected to begin in the summer of 2013, helping turn back the harmful effects of this oil spill on the City by the Bay.
Olympic Coast, Washington

Visitors flock each year to Washington’s breathtaking Olympic Peninsula to go hiking, camping, kayaking, and harvesting clams and oysters (just for starters). Driving the 350 miles along the Pacific Coast Scenic Byway, you can access an impressive amount of diversity along this state’s coast. From foggy sea stacks poking out of the Pacific Ocean to giant red cedars standing sentinel in old-growth forests to tide pools populated with vibrant orange and purple starfish, this coast abounds with natural wonders.
In December of 2012, however, a remote portion of the Olympic Coast received an unusual “visitor”: a 185 ton, 65-foot floating dock. Swept away from the Port of Misawa during Japan’s 2011 tsunami, it ended up beached within NOAA’s Olympic Coast National Marine Sanctuary and a designated wilderness portion of Olympic National Park. The dock was built out of plastic foam housed in steel-reinforced concrete, which had been damaged as changing tides and waves continued to shift the dock’s placement in the surf. A threat to the environment, visitors, and wildlife, its foam was escaping to the surrounding beach and waters, where it could have been eaten by the coast’s whales, seals, birds, and fish.

According to the Washington Department of Ecology website, “the intertidal area of the Olympic Coast is home to the most diverse ecosystem of marine invertebrates and seaweeds on the west coast of North America … Leaving the dock in place could [have] result[ed] in the release of over 200 cubic yards of foam into federally protected waters and wilderness coast.”
Fortunately, in March 2013, the National Park Service and NOAA worked with a local salvage company to dismantle and remove this hazard to the coast, using both federal money and a generous donation from Japan to fund the project and ensuring the Olympic Coast’s visitors can enjoy its healthy habitats for years to come.

We want you to take a bird’s eye view of restoration with our wildlife webcams. In 2006, NOAA’s Montrose Settlements Restoration Program, established to make up for a toxic DDT and PCB legacy in southern California, installed a live webcam with a close-up view of the first Bald Eagle nest to hatch a chick naturally on California’s Santa Cruz Island in over 50 years. Thousands watched as the eagle parents tended to their chick, affectionately named “Princess Cruz” by webcam watchers. Today, there are a total of five webcams on other nests around the California Channel Islands, highlighting the success of our Bald Eagle Restoration Program.
We also wanted to connect the public to the underwater world of wetlands with an underwater fish webcam. In 2010, our program installed a live webcam in Huntington Beach wetlands, where we completed one of our fish habitat restoration projects. This underwater camera demonstrates the importance of wetlands as a fish nursery and feeding area.
Watch Bald Eagles Live

What is cute and cuddly and has wings? You guessed it … a Bald Eagle chick! What is even better is that you can watch these adorable birds on live webcams that are placed near Bald Eagle nests located on Catalina and Santa Cruz Islands in the California Channel Islands right now. Viewers can watch daily as both male and female adults attend to their chicks by feeding them and keeping them warm. One of the most popular nests to watch is the West End nest on Catalina Island that has triplets for the third year in a row.
For eagle enthusiasts, there is a Channel Islands Eaglecam discussion forum where you can post or read daily nest observations, chat with other enthusiasts, or read updates from the Bald Eagle restoration team. With over 1 million hits each year, the Bald Eagle webcams have captivated audiences all over the world from January to June as these regal birds raise their young.
Diving with the Fish
If you are more interested in what lurks beneath the ocean then you should check out the live fish webcam that is broadcast from Talbert Marsh in the Huntington Beach wetlands. Since the fish webcam has been live, we have observed over 20 species of fish, diving seabirds, an octopus, nudibranchs (colorful sea slugs), and numerous other cool invertebrates. We have also seen fish spawning events, territorial displays of fish, and even sharks.
If you want to let us know what you have seen on our webcam, you can fill out our online fish webcam observation sheet. In case our solar-powered camera is down, you can check out this 10 minute clip recorded from the webcam for a snapshot of what you might normally see. The eelgrass swaying side to side is mesmerizing and you can always catch a glimpse of a fish when you log onto the fish webcam. Test your fish identification skills now!

Examining the Japanese skiff that washed up near Crescent City, Calif., on April 7, 2013. This is the first verified item from the Japan tsunami to appear in California. (Redwood Coast Tsunami Working Group)
The Consulate General of Japan in San Francisco has confirmed to NOAA that a 20-foot-long skiff found near Crescent City, Calif., is the first verified piece of Japan tsunami debris to turn up in California. Crescent City, a coastal town surrounded by redwoods, is only a twenty-mile drive from Oregon down the iconic, coastal Highway 101.
Once the skiff was found, the U.S. Coast Guard and the local sheriff’s office worked quickly to remove it from the shoreline. Help translating the Japanese writing on it came from further down the coast, from staff at California’s Humboldt State University. They traced the skiff to Takata High School, located in Japan’s Iwate Prefecture, an area devastated by the March 2011 earthquake and tsunami. A teacher from the school reportedly identified the vessel as belonging to them, which the Japanese Consulate has now confirmed.

To date, 26 other marine debris items with a confirmed connection to the 2011 tsunami have washed up in Oregon, Washington, Hawaii, Alaska, and Canada’s British Columbia.
And like so many of them, the small, flat-bottomed boat that washed up in California was thick with gooseneck barnacles, a common and widespread filter feeder that attaches itself to floating objects in the open ocean. While unusual-looking, these barnacles are not invasive and have a fascinating historical myth purporting that a type of goose developed from gooseneck barnacles because they had similar colors and shapes (a typical-if-faulty basis for classifying life in earlier eras).
However, the influx of sea creatures aboard tsunami marine debris also brings the concern that aquatic species hitching a ride to North America may make themselves at home, possibly to the detriment of marine life and commerce communities here in the United States.
A submerged compartment in the back of the Japanese boat that washed up in Long Beach, Wash., provided a refuge for five striped beakfish. (Washington Department of Fish and Wildlife/Allen Pleus)
This issue was highlighted in the unusual case of another small Japanese boat lost in the 2011 tsunami. The Sai-shou-maru came ashore near Long Beach, Wash., on March 22, 2013, but the inside of it looked like a miniature aquarium. Five live fish were swimming about in a submerged compartment at the back of the boat. They were striped beakfish, a species native to coral reefs mainly in Japanese waters, sometimes found in Hawaii, but certainly not in the cold waters of the Pacific Northwest coast.
According to the Washington State Department of Ecology website, “Besides the five striped beakfish found in the open well of the boat when it washed ashore, the Washington Department of Fish and Wildlife estimates 30 to 50 species of plants and animals were also on the Sai-shou-maru – including potential invasive species. State officials quickly removed the Sai-shou-maru from the beach and collected samples of potential invasive species including the fish, algae, anemones, crabs, marine worms and shellfish.”
However, most of the species arriving on marine debris are not invasive—even if they are hitchhikers.
Water and sediment sampling on Morrow Lake near Battle Creek, Mich., during the response to the Enbridge pipeline spill of oil sands product. August 2, 2010 (U.S. Coast Guard)
Unless there is a big spill or accident, most people probably don’t think much about different types of crude oil, where it comes from, or how it is transported.
Yet there is an ongoing national debate about Canada’s Alberta oil sands and whether to complete the Keystone XL pipeline that would carry Alberta oil sands products to refineries in the U.S. Gulf Coast. This proposed pipeline has gotten a lot of attention, but there are existing pipelines carrying oil sands products around Canada and across the border into the U.S., as well as tanker, barge, and rail operations doing the same.
The Exxon Pegasus pipeline spill in Mayflower, Ark., on March 29, 2013, was a reminder that oil sands are already being transported and, whenever oil is transported, there is risk of a spill.
Oil sands are considered an unconventional oil type that has been growing in prominence as oil prices fluctuate and production technologies improve. As a result, there are many questions about how best to respond to spills of crude oil products derived from oil sands. One of the major concerns is the buoyancy of oil sands products, and their potential to sink, especially in sediment-laden waters. The U.S. Environmental Protection Agency is still cleaning up submerged oil from the July 2010 Enbridge pipeline spill in Michigan’s Kalamazoo River.
Last week, NOAA’s Office of Response and Restoration participated in an Oil Sands Products Forum held at NOAA’s Western Regional Center in Seattle, Wash. The forum was sponsored by the Washington State Department of Ecology Spills Program, U.S. Coast Guard, and the Pacific States/British Columbia Oil Spill Task Force. The University of New Hampshire Center for Spills in the Environment facilitated the forum.
The two-day meeting included a full day of presentations and discussions about oil sands (also known as tar sands or bitumen) and their related products—covering everything from extraction, refining, and transportation to chemistry, how they move and react in the environment, and recent case studies of spill responses. Over 50 environmental specialists, oil spill planners, and responders attended from government agencies, tribal governments, nongovernmental organizations, and industry. Several oil sands experts from Canadian agencies and organizations also attended and presented.
On the second day, spill responders were presented with four different spill scenarios involving oil sands products, and the potential issues and challenges highlighted by the different spill situations were thoroughly discussed and recorded. Presentations and meeting notes will be made available through the Center for Spills in the Environment. The focus of this forum was not to discuss whether or not oil sands should be exploited as a resource, but rather, how to prepare better for and then deal effectively with a spill of oil sands products when it happens.
This is a guest post by University of Washington graduate students Robin Fay, Terry Sullivan, Shanese Crosby, Jeffrey Smith, Ali Kani, and Colin Groark.
Response operations near the source of the oil sands spill on Talmadge Creek near Michigan’s Kalamazoo River. August 1, 2010 (U.S. Environmental Protection Agency)
Our research has sought to provide OR&R, whose experts offer scientific support in case of a marine or coastal oil spill, with:
Background and context on oil sands development and transport.
In-depth research on the physical properties of oil sands products, national transportation networks, and emerging risks.
Analysis of the existing information and policy gaps, and some recommendations aimed at improving pollution response readiness in the event of an oil sands spill.
In doing so, we have worked to answer some key research questions, which we developed with the OR&R and other stakeholders (e.g., Washington State Department of Ecology), including:
Would oil sands products sink or float when spilled in salt water? What about fresh water?
How might oils sands products weather and change their physical and chemical characteristics once spilled into the environment?
How and where are oil sands products already being transported around the U.S. and Washington’s Puget Sound?
What are the future plans for expanding the national transportation network for oil sands products?
Our research took us into the technical depths of petroleum chemistry, state-of-the-art oil spill response technology, federal and state regulations, human and environmental health implications, and several types of transportation networks. From early on, it was clear to us just what a complex and far-reaching issue oils sands development really is. In some cases, trying to find answers just led to more questions. Although there are still many things we don’t know for sure and further research is needed, we ultimately were able to get closer to understanding the unique risks and challenges oils sands products pose to pollution responders and the environments they work to protect.
Here are our top five research findings:
All oil sands products are not created equal. They are not homogenous and are not easily categorized by any particular set of characteristics. Their composition and physical properties can vary widely based on many factors, including: what region the product originated from, what chemicals or substances it has been blended with, and how much processing or upgrading it has gone through prior to transport. This means that anticipating appropriate response action for a diverse array of products labeled as “oil sands” is somewhat of a moving target.
Very little is known about how oil sands products might weather (or change) in the environment.Some studies have been done on this topic[1], but they have typically tested one or two specific oil sands products in a laboratory setting. Their results cannot be presumed to represent the full range of possible weathering scenarios (e.g., the varying influence of waves, sunlight, wind, etc). Understanding how an oil changes as it weathers in the environment is critical to planning and executing an effective spill response.
The United States already receives almost 1.4 million barrels per day of oil sands products from Canada. This oil is transported all over the country by pipeline, rail, tanker ship, and barge. Although the proposed Keystone XL pipeline project is certainly the most visible oil sands infrastructure expansion project currently in the works, it is far from the only one. Many other pipeline expansion and terminal projects have been proposed—such as the Trans Mountain and Northern Gateway expansions proposed by Kinder Morgan and Enbridge—which would bring Alberta oil into Western Canada and even as far as Cherry Point and Anacortes, Wash. If completed, they could more than double the capacity to transport oil sands products into the U.S.
While pipeline projects—like the Keystone XL—have met fierce resistance from environmental groups, tribes, and others concerned about the risks these projects might present to their communities, the oil industry already has begun (without fanfare) to use rail for transporting oil sands products instead. Because the network of rail lines already exists, and the regulatory framework governing oil transport by rail is less developed, this segment of their transportation has been expanding rapidly. The full extent of current and planned oil sands transport by rail is unknown.
During our assessments,we found critical gaps in the current oversight, rules and regulations, contingency planning requirements, and response capacity to address the increasing transport of oil sands products. In order for regulators and responders to address effectively the emerging risks associated with oil sands products, these gaps must be addressed. Response equipment needs to be developed that is proven to be effective at detecting, containing, and removing oil sands products from the environment. Disclosure requirements for those processing and transporting oil sands products need to be improved so that regulatory agencies can better understand where and how to prioritize their efforts. Additionally, oversight, risk assessment, and contingency planning should be enhanced to take into account the increasing possibility of a spill of oil sands product. This need and the lack of adequate response capacity for oil sands products have been highlighted by the recent spills in Minnesota and Arkansas.
That’s a tall order, and unlikely to happen overnight. But there is some good news. Locally in Washington state, the Washington State Department of Ecology and U.S. Coast Guard in Sector Puget Sound have been pioneers. They are already working to improve their ability to prevent, plan for, and respond to an oil sands product spill. Last December, a conference in Portland, Maine, brought experts together from across the U.S. and Canada to discuss oil sands, and a similar conference recently was held in Seattle on April 16.
Stakeholders and policy makers we spoke with on both coasts, in the Great Lakes region, and in Canada have all begun to consider how increased oil sands development affects their region or function. Oil sands slowly are beginning to appear with greater prominence on the agenda for decision makers, not just for a particular state or project, but as an issue that spans political and geographic boundaries. If oil sands development and transportation continues to receive more and more attention, we hope it will also receive the oversight and response resources necessary to address sufficiently the risks that come with it.

Around 100,000 residents call North Charleston, S.C., home, and since 2000, more and more people have been flocking to this urban center that balances the benefits of a lively port city with the rich history and natural beauty of a southern coastal town. Yet this isn’t by coincidence. It’s by decision and design. The City of North Charleston actively promotes a prosperous and livable community, which includes restoring green spaces and opening public access to the hard-working waterfront.

At the end of September in 2002, as the container ship M/V Everreach pulled away from North Charleston for its next destination, approximately 12,500 gallons of oil spilled out of it and into the waters of the Cooper River and Charleston Harbor.
The oil was seen over some 30 miles of shoreline and sediments, including tidal flats, fringing marshes, intertidal oyster reefs, sandy beaches, and manmade structures (e.g., docks, piers, bulkheads). Most of the oil concentrated in the vicinity of the North Charleston Terminal on the Cooper River and old Navy base piers and docks.
This spill impacted pelicans and shorebirds, closed a shellfish bed operation, and temporarily disrupted recreational shrimp-baiting in local waters.
The state and federal agencies charged with preserving the area’s public natural resources—NOAA, U.S. Fish and Wildlife Service, South Carolina Department of Health and Environmental Control, and South Carolina Department of Natural Resources—worked cooperatively with the ship’s owner, Evergreen International, to determine the resulting environmental injury and resolve legal claims for natural resource damages.
From Marsh to Golf Course and Back Again
After carefully assessing the impacts, we the natural resource trustees worked with North Charleston’s property owners, developers, and local officials to restore a marsh-turned-naval golf course back into a functioning wetland that could support birds, fish, invertebrates, and vegetation.

Back in 1901, decades before North Charleston became its own city, the City of Charleston provided riverfront land to the U.S. Navy to develop a naval base. This also involved converting a marsh on the base into a golf course. The former Navy golf course along Noisette Creek in North Charleston was used until the base closed in 1996 and the property was transferred back to the City of North Charleston with a small portion owned by the Noisette Company. In 2002, the city and Noisette Company began arrangements and planning for the Noisette Preserve, a 135 acre “recreation and nature preserve at the heart of the redevelopment, located around Noisette Creek and its marshes, creeks and inlets” [Final Restoration Plan and Environmental Assessment, PDF]

To increase the tidal exchange and drainage needed to restore this area to a salt marsh, the project required removing a berm in two areas along Noisette Creek and constructing a network of tidal creeks throughout the property, which also provides access for recreational paddlers. Roads, drainage tiles, rip-rap, and other sources of debris were removed during the process as well.
As a result, the public will be able to enjoy a beautiful living shoreline which supports the surrounding area’s ecological services and ultimately benefits activities like boating, fishing, shellfish harvest, and shrimp baiting.
Supporting Green Communities
In cooperation with Evergreen International, we will monitor the wetland enhancements over the next five years to ensure the project achieves the desired ecological improvements. This project, the first of the planned restoration completed for the Noisette Creek Preserve, has created momentum and excitement for several similar projects slated for this small urban watershed. By aligning these restoration efforts with the larger goals for the City of North Charleston’s smart and sustainable growth, we and our partners have been able to build stronger, greener coastal communities and support a thriving local economy—a success for both the environment and the people of North Charleston.
Readers, how are you supporting resilient and sustainable coastal communities near you this Earth Day (and every day)?

To clean, or not to clean: That is the question.
And if you’re going to clean, how best to do it? This is a question that responders face whenever oil ends up on a shoreline after an oil spill. It’s a particularly difficult question when this happens on the shoreline of marshes.
Although we may sometimes think of marshes as murky, swampy, or smelly, marshes are highly sensitive environments with soft sediments that support a huge diversity of creatures, including birds, mammals, fish, crabs, and shrimp. Marshes are also incredibly productive habitats that act as nurseries for many juvenile organisms and whose large amounts of decaying plant material are the base of a complex food web. They also provide other important ecological services like storm surge protection and shoreline stabilization and water quality improvement. In many instances, when marshes get oiled, the best response action is no response—meaning no human-led cleanup. In the spill response world, we call this “natural recovery.”
Natural recovery is often the best option for an oiled marsh because nearly all types of active cleanup will include some unintentional habitat damage or disturbance. This can stem from the type of equipment used, the way it is used, or the mere presence of cleanup workers disturbing wildlife or trampling the marsh vegetation. The last 40 years of cleaning up oil spills in marshes has demonstrated that active, aggressive cleaning can cause as much or more short- and long-term damage than leaving the oil in place to break down naturally.
When Natural Recovery Is Not Enough
So, when over 30 miles of sensitive salt marshes in Louisiana’s Northern Barataria Bay were heavily oiled as a result of the 2010 Deepwater Horizon oil spill, natural recovery was the preferred approach. However, in the areas with the most substantial and persistent oiling, the oil did not appear to be weathering or naturally degrading over time.
After the 2010 Deepwater Horizon spill, a heavy layer of oiled vegetation mats were preventing the thick emulsified oil underneath from breaking down along Barataria Bay’s marshes. (NOAA/Scott Zengel)
In these areas, a dense, heavy layer of oiled, matted vegetation was lying overtop thick, fresher-looking emulsified oil (meaning it had water mixed in it). The vegetation mats were limiting the oil’s exposure to sunlight, air circulation, and tidal flushing—all natural factors which help break down oil. A number of “traditional” methods of marsh cleanup were tried earlier in the spill response, including low-pressure flushing with ambient seawater, skimming, vacuuming, applying materials to absorb the oil, and natural recovery. However, they performed poorly and in some cases caused additional damage to the marsh.
So what to do? Since the tried-and-true, traditional methods of cleanup weren’t working, this spill’s Shoreline Cleanup and Assessment Technique (SCAT) program (which surveys an affected shoreline after an oil spill) proposed a field test of various treatment methods, led by the oil spill science experts on NOAA’s Scientific Support Team. In addition to proposing a series of test treatments, they set aside several “no treatment” (natural recovery) sites with similar oiling conditions, and established nearby reference sites as well, both for later comparison to the treated sites.
All of the proposed test treatments included cutting the oiled vegetation to expose the thick oil beneath it, in order to accelerate weathering of the oil. In addition to vegetation cutting, the following treatments were tried:
Using two different chemical shoreline cleaners that are designed to make oil “lift and float.”
Low-pressure flushing.
Marsh vacuuming.
Weed Whackers, Rakes, and Hedge Trimmers
As it turned out, conventional “weed whackers” were no match for the dense, heavily oiled vegetation mats, even when we tried different cutting techniques and cutting attachments. So we raked the vegetation. In the end, the only treatment that showed promise was the vegetation raking.

As we monitored the treated plots, however, we found that the ebb and flow of the tide laid the raked vegetation back down on the marsh, reforming the oiled vegetation mats and continuing to trap the layer of thick emulsified oil on the marsh surface. It quickly became apparent to us SCAT program scientists that any successful treatment would require removing the oiled vegetation. A fresh round of investigation into cutting devices began.
Ultimately, a heavy-duty, commercial power hedge trimmer was the solution. It was successfully used to cut through the dense, heavily oiled mats of laid-over vegetation and to cut oiled vegetation that still stood upright. By aggressively raking the oiled vegetation and the thick oil layer on the surface of the marsh, we were able to remove much of the oil, reducing the surface oiling and risk of re-oiling other vegetation.
Initial monitoring showed that this approach resulted in completely removing the heavily oiled vegetation mats in the raked and cut plots. Most importantly, the character of the remaining oil on the marsh area changed from mostly thick emulsified oil to a predominance of more weathered surface oil residue that posed far less of a risk to wildlife or for refloating and re-oiling the marsh.
In all, seven miles of the most heavily oiled areas in Northern Barataria Bay, La., were treated by raking and cutting. Most of this work was conducted by hand, using walk boards to reduce the foot traffic in the marsh. It appears that the treatment was effective and that impacts to the marsh from the cleanup action were limited.

We are continuing to monitor the test plots in order to fully understand whether this cleanup action was the best approach and what the ecological effects or impacts of “treatment” versus “no treatment” are. Stay tuned for a future post that explores the results of the data collected thus far.
