Blue Crab Babies and Microplastics jennifer.simms Fri, 04/03/2020 - 09:19

Microplastics, or plastic pieces smaller than 5mm in size, are commonly found in our ocean and coastal waters. Do the microplastics that these larval crabs encounter while drifting in the ocean affect their survival and ability to return to estuaries? With support from a NOAA Marine Debris Program Research grant, a team of University of Delaware marine scientists have joined forces to study this question.

Connected by the Sea and Combating Debris in the Pacific

Posted Thu, 02/13/2020 - 15:39

The Pacific Ocean bonds and connects many islands and people throughout the region. These communities share in the art and science of traditional navigation, which has fostered an intimate attachment to the ocean over many generations. Today, these island communities also share in the struggle of mitigating marine debris as they work to protect the ocean.

Source-to-Sea, Addressing Marine Debris in California

Posted Mon, 01/27/2020 - 10:02

California is home to 12% of the nation’s population, with 26 million people living in counties along its 3,427 mile coastline. The average American generates an average of 4.5 lbs of trash per day (EPA estimate as of 2017) multiplied by 26 million people, that's 117,000,000 lbs of trash generated just from California's coastal population for one day! Inevitably some portion of that waste is littered, lost, or “leaked” through waste management and can eventually reach California’s coastal ocean and become marine debris.

Celebrating the New Year Glitter Free

The holidays have arrived and that means party decorations and celebrations! Last week, the Marine Debris Program highlighted how to “green” your travel plans, how to create zero waste gifts and gift wrapping, and how to host and decorate for holiday parties that celebrate the Earth too. As we wrap up 2019, we have one more piece of celebration advice: try a glitter-free New Year.

On a Mission to Research Microplastics in the Mississippi River

The growing tide of plastic debris in our ocean is partially due to the steady discharge of plastic by our rivers that drain into the sea. Plastics materials enter waterways from rural and urbanized areas located near riverbanks, and then travel downstream with the flow. Plastic comes in a variety of sizes and includes both macroplastics (large enough to be seen with the naked eye) and microplastics (not easily seen with the naked eye and are about 5 mm in size; about the size of a pencil eraser).

Understanding Microplastics In Seafood

Research is an important part of our fight against marine debris. It allows us to advance our understanding of how debris impacts the environment, and improves our ability to target and address the problem in the future. Recent research has shown that marine debris, such as microplastics (plastics less than 5mm in size), can be ingested by fish and species that filter their food out of the water. In order to improve our understanding of marine debris, the NOAA Marine Debris Program supports original and hypothesis-driven research projects which focus on the potential risk to wildlife from debris exposure and ingestion.

The Results are in for the Status of Marine Debris on U.S. Shorelines!

Posted Wed, 06/27/2018 - 16:31

Have you ever wondered how much marine debris is on the shoreline of the United States, or what areas of the country have the most debris? What about the most common types of debris in different regions of the United States? These are a few of the questions that were answered by analyzing data from the Ocean Conservancy’s 30-year International Coastal Cleanup, as well as five years’ worth of data from NOAA's Marine Debris Monitoring and Assessment Project.  The NOAA Marine Debris Program funded a rigorous statistical analysis of both datasets performed by the Ocean Conservancy (OC), together with the Commonwealth Scientific and Industrial Research Organisation (CSIRO). We are now pleased to share these exciting results!

Microplastic Pollution: A complex mixture of diverse polymers, shapes and sizes

The microplastics literature is growing at a tremendous rate. Every day, new studies are published about their sources, fate, and effects. There is no longer any doubt that microplastics of all shapes, sizes, and types contaminate diverse ocean habitats and animals. We also understand much more about the effects of microplastics on organisms than we did just a few years ago. Still, there are research gaps to fill. As part of a project funded by the NOAA Marine Debris Program, we set out to answer questions related to these research gaps. We examined whether environmentally-relevant concentrations of different types of microplastics directly affect freshwater prey and indirectly affect their predators. Check out the results which were just published.

The NOAA Marine Debris Program Awards Funding to Four New Projects to Research Marine Debris

Posted Tue, 08/29/2017 - 12:30

After an intensive evaluation process, the NOAA Marine Debris Program is proud to announce the four recipients of our 2017 research awards, totaling $935,156 of funding toward marine debris research efforts. Marine debris is a relatively new field of research, and there are many opportunities to advance understanding of how debris impacts the environment. The NOAA Marine Debris Program held a nationwide competitive funding opportunity to support original, hypothesis-driven research projects focused on the ecological risk assessment, exposure studies, and fate and transport of marine debris. Check out this year's funded projects.
