Where Are the Pacific Garbage Patches Located?

Microplastics in sand.

Microplastics, small plastics less than 5 millimeters long, are an increasingly common type of marine debris found in the water column (including the “garbage patches”) and on shorelines around the world. Based on research to date, most commonly used plastics do not fully degrade in the ocean and instead break down into smaller and smaller pieces. (NOAA Marine Debris Program)

The Pacific Ocean is massive. It’s the world’s largest and deepest ocean, and if you gathered up all of the Earth’s continents, these land masses would fit into the Pacific basin with a space the size of Africa to spare.

While the Pacific Ocean holds more than half of the planet’s free water, it also unfortunately holds a lot of the planet’s garbage (much of it plastic). But that trash isn’t spread evenly across the Pacific Ocean; a great deal of it ends up suspended in what are commonly referred to as “garbage patches.”

A combination of oceanic and atmospheric forces causes trash, free-floating sea life (for example, algae, plankton, and seaweed), and a variety of other things to collect in concentrations in certain parts of the ocean. In the Pacific Ocean, there are actually a few “Pacific garbage patches” of varying sizes as well as other locations where marine debris is known to accumulate.

The Eastern Pacific Garbage Patch (aka “Great Pacific Garbage Patch”)

In most cases when people talk about the “Great Pacific Garbage Patch,” they are referring to the Eastern Pacific garbage patch. This is located in a constantly moving and changing swirl of water roughly midway between Hawaii and California, in an atmospheric area known as the North Pacific Subtropical High.

NOAA National Weather Service meteorologist Ted Buehner describes the North Pacific High as involving “a broad area of sinking air resulting in higher atmospheric pressure, drier warmer temperatures and generally fair weather (as a result of the sinking air).”

This high pressure area remains in a semi-permanent state, affecting the movement of the ocean below. “Winds with high pressure tend to be light(er) and blow clockwise in the northern hemisphere out over the open ocean,” according to Buehner.

As a result, plastic and other debris floating at sea tend to get swept into the calm inner area of the North Pacific High, where the debris becomes trapped by oceanic and atmospheric forces and builds up at higher concentrations than surrounding waters. Over time, this has earned the area the nickname “garbage patch”—although the exact content, size, and location of the associated marine debris accumulations are still difficult to pin down.

This map is an oversimplification of ocean currents, features, and areas of marine debris accumulation (including “garbage patches”) in the Pacific Ocean. There are numerous factors that affect the location, size, and strength of all of these features throughout the year, including seasonality and El Nino/La Nina. (NOAA Marine Debris Program)

The Western Pacific Garbage Patch

On the opposite side of the Pacific Ocean, there is another so-called “garbage patch,” or area of marine debris buildup, off the southeast coast of Japan. This is the lesser known and studied, Western Pacific garbage patch. Southeast of the Kuroshio Extension (ocean current), researchers believe that this garbage patch is a small “recirculation gyre,” an area of clockwise-rotating water, much like an ocean eddy (Howell et al., 2012).

North Pacific Subtropical Convergence Zone

While not called a “garbage patch,” the North Pacific Subtropical Convergence Zone is another place in the Pacific Ocean where researchers have documented concentrations of marine debris. A combination of oceanic and atmospheric forces create this convergence zone, which is positioned north of the Hawaiian Islands but moves seasonally and dips even farther south toward Hawaii during El Niño years (Morishige et al., 2007, Pichel et al., 2007). The North Pacific Convergence Zone is an area where many open-water marine species live, feed, or migrate and where debris has been known to accumulate (Young et al. 2009). Hawaii’s islands and atolls end up catching a notable amount of marine debris as a result of this zone dipping southward closer to the archipelago (Donohue et al. 2001, Pichel et al., 2007).

But the Pacific Ocean isn’t the only ocean with marine debris troubles. Trash from humans is found in every ocean, from the Arctic (Bergmann and Klages, 2012) to the Antarctic (Eriksson et al., 2013), and similar oceanic processes form high-concentration areas where debris gathers in the Atlantic Ocean and elsewhere.

You can help keep trash from becoming marine debris by (of course) reducing, reusing, and recycling; by downloading the NOAA Marine Debris Tracker app for your smartphone; and by learning more at http://marinedebris.noaa.gov.

Digging for Data at the Alaska Marine Science Symposium

This is a post by NOAA Environmental Scientist Dr. Amy Merten.

As Chief of the Spatial Data Branch in NOAA’s Office of Response and Restoration, my focus is all about data. In particular, that means figuring out how to access data related to oil spills: the type of information useful for planning before a spill and for the response, environmental injury assessment, and restoration after a spill. Once we get that data, which often comes from other science agencies, universities, and industry, we can then ingest it into Arctic ERMA®, NOAA’s online mapping tool for environmental disaster data. While at the Alaska Marine Science Symposium this week, I have spent much of my time working with experts who provide and manage that kind of data.

For example, the Alaska Ocean Observing System (AOOS) provides real-time and historical coastal data to multiple stakeholders, including NOAA for Arctic ERMA. AOOS is also the host for the newly signed data-sharing agreement [PDF] between NOAA and three oil companies (Shell, ConocoPhillips, and StatOil). These companies have agreed to share the physical oceanographic, geological, and biological data they have been collecting near areas of Arctic offshore oil and gas activities since 2009. This is an unprecedented amount of data that the industry now is sharing with the federal government and the public. The data are available at www.aoos.org.

My colleague and our Arctic ERMA geographic information system (GIS) expert, Zach Winters-Staszak, attended the Arctic Mapping Workshop sponsored by our partners at the University of Alaska Fairbanks GINA program. Their geographic information network gives us access to high-resolution base maps, imagery, high frequency radar, ice radar, webcams, and more.  Zach learned about new data sets and new ways for pulling high impact data into Arctic ERMA.

Another helpful information source I learned more about was NOAA’s ShoreZone project.  ShoreZone [PDF] is a popular Pacific Northwest dataset of high-resolution aerial videos and photographs of the shoreline in Alaska, British Columbia, Washington, and Oregon at extreme low tide. The photos and videos are augmented with habitat classifications of the different zones along the shoreline, such as salt marsh or kelp beds. We already pull in ShoreZone data layers into our Arctic and Pacific Northwest ERMA sites.

These data are valuable for preparedness and response to oil spills and for understanding places where oil and marine debris may accumulate naturally. It’s especially useful for understanding what the shoreline might look like before going out to survey for signs of oil or marine debris accumulation. It can help you decide how you’re going to access the shore (boat, helicopter, on foot) and what you might expect to find. ShoreZone surveyed the Kotzebue and North Slope regions of the Alaskan Arctic this past summer, which we’re excited to draw into Arctic ERMA when they are available.

Read more about Arctic ERMA and our plans for this environmental data tool.

Report Reveals Hudson River and Wildlife Have Suffered Decades of Extensive Chemical Contamination

Sign by Hudson River warning against eating contaminated fish.

According to the report, “Fish not only absorb PCBs directly from the river water but are also exposed through the ingestion of contaminated prey, such as insects, crayfish, and smaller fish…New York State’s ‘eat none’ advisory and the restriction on taking fish for this section of the Upper Hudson has been in place for 36 years.” (NOAA)

The Hudson River Natural Resource Trustees, including NOAA, released a report today outlining the magnitude of toxic chemical pollution in New York’s Hudson River. The report, “PCB Contamination of the Hudson River Ecosystem” [PDF], documents six years of data and analysis showing that the Hudson River, for more than 200 miles below Hudson Falls, N.Y., is extensively contaminated with polychlorinated biphenyls (PCBs).

Starting in 1947 and for approximately 30 years, manufacturing plants operated by General Electric Company (GE) discharged PCBs into the upper Hudson River,  with additional releases of PCBs occurring as well.

According to the report, PCBs are a “group of highly toxic compounds that are known to cause cancer, birth defects, reproductive dysfunction, growth impairment, behavioral changes, hormonal imbalances, damage to the developing brain, and increased susceptibility to disease in animals.” Hazardous at even very low levels, they make their way up the food chain and become stored in the tissues of wildlife and fish, posing a health threat if people consume them.

Analysis of the river from 2002 to 2008 shows that PCBs permeate nearly every part of the river: surface waters, sediments, floodplain soils, fish, birds, wildlife, and other natural resources. The report further documents decades of high levels of PCBs and likely harmful effects on living organisms exposed to the contamination in the Hudson River. PCB levels in fish were often 10 or more times the U.S. Food and Drug Administration’s (FDA) standards for safe consumption (pp. 10) and in water samples tested “10 to 10,000 times higher than that deemed safe for aquatic life, fish-eating wildlife and human consumers of fish” (pp. 5).

As a result of this pollution, the public has lost the use of these natural resources, for example, due to restrictions and advisories for catching and eating fish and navigational losses due to contamination of the Champlain Canal.

A Hudson River PCB Forum is being held on January 16, 2013 at Marist College in Poughkeepsie, N.Y. The intent of the forum is to provide mid-Hudson communities with an update on the PCB dredging project and restoration planning by the Natural Resource Trustees.

Looking out for Sea Lions and Salmon Before a Grounded Rig Could Spill a Drop of Oil

This is a post by OR&R’s Alaska Regional Coordinator Dr. Sarah Allan.

conical drilling unit Kulluk sat aground on the southeast shore of Sitkalidak Island

Here you can see the rocky coast and habitats near where the conical drilling unit Kulluk sat aground on the southeast shore of Sitkalidak Island about 40 miles southwest of Kodiak City, Alaska, in 40 mph winds and 20-foot seas on Tuesday, Jan. 1, 2013. (U.S. Coast Guard)

Fortunately, when Royal Dutch Shell’s offshore drilling platform, the Kulluk, ran aground on a remote Alaskan island on New Year’s Eve, it did not lead to an oil spill. However, the rig held 140,000 gallons of diesel fuel, and throughout the response, the potential for a spill remained a concern.

This was especially true because the Kulluk was located in an area with many sensitive natural resources, including harbor seals, marine birds, critical habitat for Steller sea lions, and salmon streams. On top of that, pacific cod and tanner crab harvests take place in that part of Sitkalidak Island, south of Kodiak. Subsistence foragers from the Old Harbor Native village harvest razor clams from a bed near the grounding site.

In light of the potential for an oil spill, restoration specialists from NOAA’s Office of Response and Restoration, collaborating with federal and state natural resource trustees, began planning an assessment of the possible harm to natural resources. What if the oil did spill and impact those natural resources? How would we determine what was injured and how badly?

Spill Today, Gone Tomorrow

One of the first steps in this planning effort was to consider where the diesel might go if it spilled and what natural resources it might impact. Spill responders—those considering oil cleanup options—often see diesel spills as less of a concern than spills that involve thicker, heavier oils. This is due to the way that diesel acts when it is spilled on the ocean surface; most of it evaporates into the air and disperses into the water in a few hours, especially in high winds and waves. In this case, NOAA scientists estimated that almost all of the Kulluk’s diesel would evaporate or disperse in 4–5 hours if it spilled. This means there would be very little oil for cleanup workers to try to recover from the water’s surface.

The Kulluk was grounded near shore and, in the event of a spill, the wind and waves would have pushed the diesel towards the shoreline. In this scenario, diesel could have impacted nearby ocean areas, beaches, rocky shorelines, and stream outlets. The Unified Command took precautionary measures during the grounding and removal of the Kulluk, which included placing containment boom across the mouths of streams in the area to keep out any potentially spilled diesel.

A Toxic Shock

Though diesel may not remain for very long in the environment, it is very toxic to many aquatic species. A diesel fuel spill would have had an immediate and negative effect on the environment. In high seas, like those around the grounded Kulluk, as much as 90 percent of the diesel would disperse into the water. The dispersed diesel could affect marine organisms that live in the water column, on the ocean bottom, or along the shoreline.

Past spills of comparable fuels in similar marine environments have killed large numbers of organisms living in the water column or on the ocean bottom in the area where the oil was released: the barge North Cape grounded and spilled oil off Rhode Island during bad weather in 1996, and the ship Tampico Maru grounded and spilled diesel on a remote, rough shoreline in Northern Baja California in 1957.

Diesel is acutely toxic to many zooplankton, bivalve, and crustacean species as well as unhatched and young salmon. Organisms can become “tainted” when they are either exposed to diesel at levels that don’t kill them (sublethal) or when they eat other organisms exposed to those levels. In that case, responders would test seafood for safety, and those of us evaluating environmental damages would assess marine organisms’ exposure levels with additional testing. Even these sublethal exposures can cause toxic effects that need to be considered in a damage assessment.

While initially preparing for a potential damage assessment, we focused on planning for water, sediment, and bivalve (razor clams and blue mussels) sampling as well as on planning shoreline assessments for evidence of injured or dead animals. If we could do this sampling before and/or immediately after a spill, we would have a more accurate assessment of damages to natural resources. Assessing exposure and injury to natural resources is time sensitive, especially in the case of a short-lived contaminant like diesel.

Weather Or Not

However, the far-flung location of the grounding site, as well as the harsh weather conditions, would make sampling in the area challenging. Our planning had to address those logistical challenges. That meant having resources and personnel standing by 40 miles away in Kodiak City, Alaska; arranging for transportation to the site of the rig; securing permission to access the area, and procuring the resources we needed to sample. Given the conditions, accessing the site would have required a helicopter or boat trip to the island and overland transit through grizzly bear habitat, across rough terrain, and private property.

Again, we’re happy that the diesel aboard the Kulluk stayed in its tanks while the rig was grounded and moved off of Sitkalidak Island. But new opportunities for oil drilling, commerce, and tourism in the Arctic are expected to bring more marine traffic through these areas. That creates more opportunities for accidents. It is important for us to be prepared to undertake a natural resource damage assessment in the event of an oil spill. Understanding what is at risk, what to expect from the particular oil spilled, and how it all fits in a specific environment is the first step.

NOAA Tracks Path of Possible Japan Tsunami Dock off Washington Coast

This is a post by Amy MacFadyen, oceanographer and modeler in the Office of Response and Restoration’s Emergency Response Division.

A dock washed up on the rocky northern coast of Washington.

As a NOAA oceanographer working in pollution response, part of my job is to predict where pollutants (mostly oil) spilled into the ocean will end up. Sometimes I am asked to forecast possible paths, or trajectories, for other objects spotted at sea—such as a large dock recently reported to be floating off the coast of Washington state, approximately 16 nautical miles northwest of Grays Harbor.

We suspect [Editor's note 1/18/13: Japan has confirmed this as a piece of tsunami debris.] that this dock began its oceanic journey in March of 2011 at the Port of Misawa, Japan, following the devastating Tōhoku earthquake and subsequent tsunami. Three* docks were ripped away from this port.  After approximately 15 months at sea, one of the docks turned up on Agate Beach near Newport, Ore., in June 2012. A second dock suspected** to be from Misawa was spotted offshore of the Hawaiian Islands in September. The vast difference in the paths of these three docks is a good illustration of how turbulent ocean currents and winds can scatter widely objects floating at sea.

When this latest dock was spotted on Friday, December 14, we at NOAA were asked to forecast where winds and currents might move the dock over the next few days. The dock is a large, unlit, concrete structure and hence posed a significant hazard to navigation. Furthermore, with stormy weather and strong onshore winds in the forecast, it seemed likely the dock would end up on the beach. Many beaches along the northern Washington coast are quite remote, varying from sandy or rocky beaches to cliffs dropping right down to the water. Depending on where the dock came ashore, access could prove difficult and might allow possible invasive species hitching a ride on the dock time to spread into local ecosystems. To be better prepared to take action, we needed to know where and when the dock might come ashore so it could be located quickly.

In order to predict the trajectory of an object floating at sea, we require forecasts of winds and ocean currents. Those of us who live in the Pacific Northwest are especially familiar with the difficulty involved in predicting the weather. Although weather forecasts are generally reliable for the first few days of a forecast period, a forecast always contains some uncertainty which tends to increase over time. For example, this weekend’s weather forecast is generally more accurate than next weekend’s forecast.

Forecasting ocean currents faces similar difficulties, which may be compounded by a lack of observations. There are few (if any) direct measurements of real-time ocean currents on the Washington coast. In addition, there is further uncertainty about how a floating object such as a large dock will move in response to the currents and winds. For example, an object that is floating high in the water will “feel” the winds more than an object floating lower in the water. While we could estimate this effect for the dock, it adds another source of uncertainty to the mix.

Map of the northern Washington coast shows projected and actual locations of the dock.

This map of the northern Washington coast shows an example output from the GNOME model for the predicted “best guess” area (red ellipse) and uncertainty boundary (blue ellipse). The location where the dock was found is shown by the black arrow. (NOAA)

So what can we do with all this uncertainty when “I don’t know” is not an acceptable answer? The approach we took was twofold. In addition to providing a “best estimate” trajectory for the dock, in which we considered the wind and currents forecasts as truth, we also ran multiple scenarios in our trajectory model to determine where else the dock possibly could end up. These additional scenarios might use different values approximating how much the dock gets pushed along like a sailboat or they might adjust the wind and current forecasts slightly to see how this affects the projected path of the dock.

After running the trajectory model multiple times, we produced a map that indicated the most likely area that the dock would come ashore, but the map also included a larger area of uncertainty around it (an “uncertainty boundary”) where the dock might be found if, for example, the currents were stronger than predicted.

Because the dock was not spotted again after the initial report on December 14, our trajectory could only narrow down the search area to an approximately 50 mile stretch of the Washington coast (remember, forecast error grows with time).

However, using the forecast guidance, state, federal, and tribal representatives mobilized search teams, and the dock was located on the afternoon of December 18 by a Coast Guard helicopter aerial survey. The dock had been washed ashore, most likely sometime during the evening before, on a rugged stretch of coastline north of the Hoh River. Access to the region is difficult, but personnel from the National Park Service and Washington State Fish and Wildlife are attempting to reach the dock to sample it for invasive species and to attach a tracking buoy in case it refloats before it can be salvaged.

Here you can see an example animation of our trajectory model GNOME showing a potential path of the dock. Particles are released in the model at the position where the dock was initially sighted. The particles move under the influence of winds and ocean currents. They also spread apart over time; this is simulating the small-scale turbulence in the winds and currents. This particular scenario was run after the dock was stranded and uses observed winds from a nearby weather station (wind direction and strength is shown by the arrow on the upper right) and a northward coastal current of approximately 1 knot.

Download the video animation showing the potential path of the dock off the coast of Washington [Quicktime].

*[UPDATE 4/5/2013: This story originally stated that four docks were missing from Misawa, Japan and that "one of the four turned up several weeks later on an island south of Misawa." We now know only three docks were swept from Misawa in the 2011 tsunami, and none were found on a Japanese island.]

**The dock near Hawaii has not been confirmed by the Japanese Consulate as being from Misawa.

Submit Your Comments: Studying Decades of Environmental Injuries at the Hanford Nuclear Site

This is a post by OR&R’s Charlene Andrade, Mary Baker, and Vicki Loe.

Nuclear reactors line the riverbank at the Hanford Site along the Columbia River in January 1960.

Interesting things are happening at Hanford. After decades of nuclear production, years of cleanup, and chronic contamination, the time has come to begin restoring the land and natural resources of Hanford, Wash. That’s why NOAA, along with other agencies and tribes, has started a natural resource damage assessment and is now publishing a document for public review. The Draft Injury Assessment Plan [PDF] describes the first phase of the restoration process, which is to quantify harm to natural resources at the Hanford Nuclear Site.

For those of you unfamiliar with the history of the site, between 1944 and 1987, Hanford, located in eastern Washington state, produced plutonium for atomic weapons, starting with the “Fat Man” bomb dropped on Nagasaki, Japan, in 1945. During the Cold War years, the facilities grew to include nine nuclear reactors and associated processing plants. For decades, Hanford produced radioactive materials for Cold War-era military activities, commercial nuclear energy production, and nuclear medicine. These operations led to the release of radionuclides and contaminants into the arid landscape and the Columbia River, which borders the site, injuring the habitats, wildlife, and people’s ability to enjoy the area for recreational and cultural uses.

F Area is home to F Reactor, the third of Hanford’s nine plutonium production reactors built to produce plutonium for the nation’s defense program during both World War II and the Cold War. The reactor operated from 1945 to 1965 and was placed in interim safe storage in 2003. (U.S. Dept. of Energy)

Cleanup at the site began in 1989 and likely will continue well into the future. However, we are concerned about the chronic environmental impacts and believe there is a need to begin restoration now to offset the more than 30 years of injury. Our efforts are different than cleanup. Cleanup involves removing contaminated materials such as buildings, waste, and soil from the landscape.

Restoration, on the other hand, involves accounting for and offsetting the harm done to natural resources that continue to feel these impacts while waiting for full cleanup at the site. For example, during past operations at Hanford, leaks and overflows caused contaminants from nuclear reactors to flow directly into the Columbia River, and even though the facilities have long since been closed, the contaminants in the groundwater, such as chromium, have continued to leach into the river to the present day. These contaminants have reached Chinook salmon spawning grounds and the forage and resting areas for sensitive young salmon near the shoreline.

This is why NOAA, other agencies, and local tribes believe it is time to begin restoration planning.

The Draft Injury Assessment Plan, which is available for your review, is the first step in planning restoration. We are required by law to describe and quantify harm to impacted habitats and species before we can begin restoration on land or in the river, and we have created a Draft Injury Assessment Plan to accomplish that.

No one has completed this kind of assessment at Hanford before, and it will be a challenging and complex task. First, we will pull from existing scientific studies, Hanford site documents, and historical information to create a picture of what harm has been done to the natural resources. Then, we will plan additional studies only where the picture is not already clear.

Once we fill in these missing pieces with data, we will be better prepared to determine the scale and type of restoration needed and begin the appropriate projects. Assessing past, present, and future environmental injuries will not be easy, which is why we need your input on our plan.

Let us know what you think of our proposed approach. You can find out more about our efforts and obtain copies of the Draft Injury Assessment Plan [PDF] at www.hanfordnrda.org.

Study Reveals D.C. Community near Anacostia River Are Eating and Sharing Contaminated Fish

An extensive study partly funded by NOAA has found that nearly half of the people living near Washington, D.C.’s Anacostia River are unaware of the dangers of eating its fish. The results are prompting a reexamination of how to communicate these important public health risks to a diverse, multilingual, and urban community.

The report uncovered further evidence that many local fishermen—who were disproportionately African American, Latino, or Asian—are catching, eating, and sharing potentially contaminated fish with family, friends, and others, greatly expanding the possible long-term health risks to the public. The study estimated some 17,000 people living near the Anacostia could be eating these polluted fish.

“Our research confirmed that contaminated fish are, indeed, being shared in the community,” said Steve Raabe of OpinionWorks, the company that did the survey. “What we could not have known, prior to embarking upon this effort, is the extent to which this sharing happens and the complex set of factors that drive it.”

When shown this ad during interviews with Anacostia River fishermen, one respondent answered, “This (ad) makes you just want to grill it!” This demonstrated “how difficult it is to break through to this audience with a message about unseen contaminants,” such as PCBs. (Addressing the Risk 2012 report)

A Dirty History

The Anacostia River, which runs through Maryland and the District of Columbia, has suffered from decades of pollution, mainly from runoff and hazardous waste sites. NOAA has been partnering to evaluate, clean up, and restore the Anacostia watershed since the late 1990s.

One of the most notable chemical pollutants in the river is polychlorinated biphenyls (PCBs), which have immune, reproductive, endocrine, and neurological effects, and may cause cancer and affect children’s cognitive development. This and other chemicals build up in the river bottom, where they make their way up the food chain and become stored in the tissues of fish, posing a health threat if people consume them.

Even though the District of Columbia and Maryland have been issuing warnings about eating Anacostia River fish for more than twenty years, the majority of fishermen and community members surveyed were not aware of these advisories. While both governments tell the public not to eat any channel catfish or carp, this report exposed that these are some of the most commonly caught fish in the river.

Furthermore, over half the fishermen reported that “knowing about such a health advisory” would not change whether or how they ate their catch. Researchers found at least two misunderstandings playing into this. One was the fishermen’s mistaken belief that they would be able to see contamination on the outside of the fish. Another was their assumption that getting “sick” from the fish would be immediate, in the form of food poisoning, instead of a future risk of cancer.

Hungry Now or Sick Later?

A particularly surprising result from the study was that fishermen along the Anacostia River often are approached by people who ask them to share fish because they do not have enough food.

Warning sign reading: Danger: Eating fish from this river may cause cancer.

Researchers found that this kind of direct messaging got the attention of those fishing on the Anacostia River. But simply improving warning signs may not be enough to address the root of the problem. (Addressing the Risk 2012 report)

“They will ride around in their cars and look to see if we’re catching fish and ride up and ask, ‘Have you caught anything today? Are you going to keep them?’” said one Anacostia fisherman interviewed during the study about sharing his catch with those lacking food.

The community’s apparent lack of access to enough affordable food complicates the task of merely delivering a better message about health risks.

“The answer to this problem will be far more complex than simply telling anglers not to share their catch,” said Raabe. “How can you tell someone who is hungry today not to eat fish that may pose future health risks?”

With almost three-quarters of fishermen eating or sharing the fish they catch, those involved in the study are looking at a broad range of possible fixes to this complex problem:

  • Improving health-risk messages to those most affected.
  • Creating more and better opportunities for education, such as fishing tournaments.
  • Introducing healthier alternative protein options to the community, through aquaponics (“a farming technique that grows plants and fish in a recirculating environment”) and local fish subscription services (akin to community supported agriculture programs).
  • Increasing the amount of city food gardens and farmers markets in the area.

Along with NOAA, the following organizations were involved in this study: Anacostia Watershed Society, the Chesapeake Bay Trust, Anacostia Riverkeeper, District Government, U.S. Fish and Wildlife Service, and the U.S. Environmental Protection Agency.

NOAA Awards $500,000 to Research Projects Exploring Impacts of Chemical Dispersants on Marine Habitats

The University of Maryland Center for Environmental Science in Baltimore, Md., has been awarded $150,000 to study the effects of dispersants and dispersed oil on the commercially important blue crab, a keystone species of the Gulf of Mexico and Atlantic coast, and its larvae.

Earlier this year I wrote about NOAA making funding available to study the effects of chemical dispersants on the marine environment.  NOAA partnered with the Coastal Response Research Center at the University of New Hampshire to make a formal call for research project proposals.

We received 36 proposals from researchers and universities across the U.S. and Canada and even a few from scientists in Europe. Those proposals were peer-reviewed this past summer and early fall, and while there were lots of great proposals, only three research projects could be selected for funding.

We’re pleased to announce that NOAA will provide grants, totaling $500,000, to the following studies [PDF], which will focus on:

  • Developing a worldwide quantitative database of the toxicological effects of dispersants and chemically dispersed oil.
  • Conducting research to improve understanding of chronic impacts of chemical dispersant and chemically dispersed oil on blue crabs, a commercially important species of marine life.
  • Researching public concerns and improving risk communication tools for oil spills and dispersants.

Over the next year we’ll get progress reports from the researchers, and all of the materials will be available online at the University of New Hampshire’s website.

Congress provided money for these grants out of supplemental research funding following the 2010 Deepwater Horizon/BP oil spill.
