The Mid-Atlantic coast of the United States is a large, dynamic, and diverse place. Home to over 10,000 miles of coastline and spanning from Virginia to New York, it features major metropolitan areas, iconic coastal bays and estuaries, and an incredible array of wildlife and habitats. Unfortunately, seemingly everywhere we turn, marine debris can also be found. Debris litters the Mid-Atlantic waterways and coastlines, entangles and captures wildlife, scars habitats, and harms the regional economy.

Plastic particles less than 5mm in size, known as microplastics, are found everywhere that scientists have looked, including in the coastal waters of New England. The eastern oyster is an important commercial aquaculture species that has been shown to eat microplastics. In partnership with the NOAA Marine Debris Program, marine scientists at the University of Connecticut sampled oysters in the field and performed a series of selection experiments in the laboratory to determine what types of microplastics oysters prefer to eat or reject and how that relates to what is in the natural environment.

Much of San Francisco’s beauty comes from its stunning location, surrounded by the Pacific Ocean and San Francisco Bay. San Francisco is also the second-most densely populated city in the United States and one of the country’s most-visited destinations. With so many people near so much water, the marine environment is especially vulnerable to all forms of human-made pollution, including cigarette butts, the most littered item in San Francisco and around the world.

About 70% of Californians believe their ocean and beaches are very important to California’s future and report that plastics and marine debris are a big problem on a coast near them. As a result, organizations, individuals, and volunteers from across the state are contributing an enormous and noble amount of time and energy to make California a national leader on addressing and preventing marine debris.

Following a highly competitive review process, the NOAA Marine Debris Program is pleased to announce the 25 recipients of our 2021 Removal, Research, and North America Marine Debris Prevention and Removal Grant awards totaling approximately $7.3 million in federal funds. Federal funding is matched by non-federal contributions, bringing the total investment of these marine debris projects to approximately $14.7 million.

Located about 2,500 miles to the southwest of Hawai‘i, the U.S. unincorporated territory of American Samoa lies only a hundred miles and a jump across the international dateline from its cultural neighbor, the nation of Samoa. However, both islands share a fate similar to many Pacific island nations. Over the past few decades, problems with solid waste management have been exacerbated by limited space and a steadily increasing amount of imported goods and materials. Arizona State University, in collaboration with partners in American Samoa, received a grant from the NOAA Marine Debris Program to quantify the amount of microplastics and associated contaminants in American Samoa’s marine waters and marine organisms to better understand the potential risks to ecosystems and human health.
