Lobster Trap Debris in the Florida Keys: A Look Back

The NOAA Marine Debris Program 10 year anniversary identity marker.


Over the years of the NOAA Marine Debris Program, there have been many efforts around the country to rid our waters and shores of marine debris. As part of our ten-year anniversary celebration, let’s take a look back at one of those efforts in our Southeast region.


Derelict fishing gear can cause lots of problems, including damaging important and sensitive habitats, ghost fishing, and posing hazards to navigation. Unfortunately, derelict commercial lobster and crab traps are a prominent type of marine debris in the Florida Keys.

Back in 2007, the NOAA National Centers for Coastal Ocean Science’s (NCCOS) Center for Coastal Fisheries and Habitat Research (CCFHR), funded by the NOAA Marine Debris Program, partnered with the Florida Fish and Wildlife Conservation Commission to research this issue. Using towed-diver surveys, they identified and counted trap debris as well as any other marine debris they encountered in the Florida Keys National Marine Sanctuary.

From these surveys, they found 1,408 marine debris items, almost 70 percent of which were trap-related debris! This included both ghost traps (which continue to actively fish, trapping and killing marine animals) and non-fishing traps in various stages of degradation. From their data, they estimated that over 85,000 ghost traps and over a million non-fishing traps could be found in the waters of the Florida Keys at that time. They also determined that winds likely play a role in moving derelict traps, since the surveyed trap debris was found in highest densities in coral reef habitats (a place not commonly targeted by fishermen).

Research like this is an important part in the fight against marine debris. This project helps us to understand where trap debris accumulates and thus allows us to more effectively focus removal efforts. For more information on this project, check out this old blog post, the scientific paper published from the study, and the Marine Debris Clearinghouse.

A New Study Looks at Derelict Traps in the Florida Keys

Research is an important part of our fight against marine debris, as it allows us to learn more about the topic and be better able to target and address it in the future. Thanks to a new study by our very own Chief Scientist, Amy Uhrin, we now know a little more about derelict lobster traps and how they impact habitat in the Florida Keys. Read all about it and get the link to the scientific paper in this NOAA Response and Restoration blog post.

Exciting Things Are Happening in the Southeast!

What do microplastics, nesting sea turtles, derelict crab trap floats, local fishermen, and whale guts have in common? They’re all part of some of the exciting projects going on in the Southeast region to fight marine debris! There’s lots going on in the NOAA Marine Debris Program’s (MDP) Southeast region right now, check out a quick glimpse at some of these projects supported by the MDP:

Starting down in Florida, Sea Grant is creating a network of citizen scientists to test water samples for microplastics and using that information to educate Floridians about plastic debris. Check out this project here.

The Coastal Cleanup Corporation is also working to improve the marine debris issue in Florida by removing marine debris from sea turtle nesting beaches, efforts that have been found to make a big difference in the past! Check out this project here.

Moving up the coast to South Carolina, the Department of Natural Resources (SCDNR), with the support of Fishing for Energy partners, is working to prevent the creation of derelict crab pots by field testing some sweet float rigging designs and educating recreational boaters about how to avoid trap lines. Check out this project here.

Continuing on to North Carolina, the North Carolina Coastal Federation is working with local fishermen and other partners to implement a crab pot recovery program, with the goal of creating a self-sustaining, long-term, fishermen-led program! Check out this project here.

The University of North Carolina Wilmington is also focusing on marine debris in North Carolina by educating students about the subject using hands-on lessons inside a life-sized inflatable whale classroom! Yes, they are going inside an inflatable whale, checking out its guts, and discussing how marine debris impacts animals. Check out this project here.

So many exciting things are happening in the Southeast region this year! Stay tuned to the NOAA Marine Debris Program website and this blog for updates on projects in this region and throughout the country.

Let’s Celebrate Earth Day!

Today is Earth Day and what better time to think about the impact we each have on our planet?

We’ve been talking about garbage patches this week and what we can do to fight them. The ongoing influx of marine debris into these garbage patches is what we need to address. To do this, we can each think about how we personally contribute to environmental problems like marine debris, take steps to prevent it, and get involved in cleaning up the debris that litters our communities and shores.

The Truth About Garbage Patches

You’ve likely heard the term “garbage patch” many times and it’s possible that this is what comes to mind:

A thick mass of marine debris floating at the surface of the water.

Although this is what most people picture when they think of a “garbage patch,” that’s actually pretty inaccurate. Let’s set the record straight and get to the truth about garbage patches.

First off, garbage patches have been wildly misrepresented in the media in the past, causing confusion on the subject and leading many to believe that there is a large “island of trash” in the Pacific Ocean—at least the size of Texas!— that you can walk around on. This is extremely far from reality.

To start, when people talk about “the garbage patch,” they are usually referring to the Great Pacific Garbage Patch in the Pacific Ocean—one of many garbage patches located throughout our global ocean. These garbage patches are formed as a result of rotating ocean currents called “gyres,” which pull debris into their center, creating areas with higher concentrations of marine debris. Because currents like these are dynamic, the size of these concentrated areas is constantly changing, making it extremely difficult to estimate the size of garbage patches. To learn more about ocean currents and the way they move debris, check out our webpage on how debris accumulates.

Secondly, there is no “island of trash” and you definitely can’t walk on the garbage patch. In reality, garbage patches are made up of lots of types of debris. Although you may find larger debris items floating on the surface of the water such as plastic bottles or derelict fishing nets, the majority of debris found in garbage patches is microplastics. These small plastic pieces (less than 5mm in size) are often formed from larger plastic that has broken down into smaller and smaller fragments due to exposure to the elements (plastic never truly breaks down, it just breaks into ever-smaller pieces), but can also come from products that include plastic manufactured at that size (microbeads) or from synthetic fabric that has gone through the washing machine (microfibers).

Not only is the majority of garbage patch debris extremely small, but it’s also not all located on the surface. Debris is found on the surface, throughout the water column, and all the way down to the seafloor. You can picture it more like pepper flakes swirling around in soup rather than a floating mass at the top. For these reasons, it’s actually possible to sail through a garbage patch (yes, even the Great Pacific Garbage Patch) and not even realize it!

Even though the above scene looks alright, it actually includes high concentrations of marine debris. This debris, even the small stuff, can have many harmful impacts on us and our environment. The question that usually comes up next is “why can’t we just go and clean up the garbage patch?!” Unfortunately, it’s not that simple. Open ocean cleanups are extremely difficult. Logistically, the large size and dynamic nature of the garbage patches, as well as the fact that they include debris all the way from the surface to the seafloor, makes this type of cleanup impractical, extremely costly, and really, almost impossible. Not only are there logistical concerns, but the abundance of marine life that calls these areas home can be substantially negatively impacted. We have to think, “Are we doing more harm than good?”

Because of the difficulties of directly cleaning up garbage patches, we instead focus on cleaning up our shorelines and on prevention, which is the highest priority. If we don’t stop marine debris at its source, we’ll just be cleaning it up forever! We can each contribute to these efforts by remembering to reuse, reduce, and recycle. If we each worked to reduce our impact, think what a difference we would make!

NOAA’s 2016 Northwestern Hawaiian Islands Removal Mission Sets Sail

Every year, multiple NOAA offices collaborate to support a marine debris removal effort in the Papahānaumokuākea Marine National Monument (PMNM), located in the remote and mostly uninhabited Northwestern Hawaiian Islands. Due to the PMNM’s location in relation to the North Pacific Gyre and ocean currents, this area is often highly afflicted with marine debris and these efforts are greatly needed. This year, the NOAA Pacific Islands Fisheries Science Center (PIFSC) Coral Reef Ecosystem Program of the National Marine Fisheries Service (NMFS), the NOAA Marine Debris Program, and the Papahānaumokuākea Marine National Monument of the Office of National Marine Sanctuaries have organized and supported an effort to clean Midway, Kure, and Pearl and Hermes Atolls, Lisianski and Laysan Islands, and the French Frigate Shoals. The 2016 mission launched on Tuesday, April 12th, and will work to remove marine debris for a month, until the mission ends on May 13th. Stay tuned to our blog for details about the trip, as well as the Coral Reef Ecosystem Program’s interactive daily map, and check out our social media, where you can find daily updates on this exciting effort!

Bringing Marine Debris to Attention: NOAA Administrator and Congressional Members Meet with MDP Partners

This past Friday, April 8th, was an exciting day for those fighting marine debris in Washington State. NOAA Administrator Dr. Kathryn Sullivan, Congresswoman Jaime Herrera Beutler, and representatives from the offices of Senator Patty Murray and Senator Maria Cantwell joined the NOAA Marine Debris Program (MDP) at a marine debris event in Long Beach, Washington. The event highlighted the NOAA Marine Debris Program’s ten-year anniversary, the five-year commemoration of the 2011 Japan tsunami, and the efforts of the MDP’s partners in Washington State against marine debris. The National Weather Service also participated in the event, highlighting the efforts to make Long Beach “Tsunami Ready.”

Local volunteers, as well as representatives from the Olympic Coast National Marine Sanctuary, the Washington State Department of Fish and Wildlife, the Quinault Indian Nation, The Nature Conservancy, and the Grassroots Garbage Gang provided presentations on their efforts to address marine debris.

Dr. Sullivan, Congresswoman Herrera Beutler, Bryan Stebbins (Southwest Washington Representative for Senator Patty Murray), and Dena Horton (Southwest Washington Outreach Director for Senator Maria Cantwell) spoke on the subject of marine debris and were able to learn a little more about the local problem by engaging with the many marine debris partners and volunteers in attendance.

The event culminated in a small-group cleanup at the local beach.

Bringing attention to this important subject is part of the ultimate solution to prevent marine debris and events such as this help to do that. We’d like to thank our partners for participating in this event and highlighting their efforts to combat marine debris in Washington State. For more information about this event, check out this article.
