About The SEA PLastics Lab
Studying Plastic Marine Debris for More Than 35 Years
Grounded in undergraduate student research carried out aboard SEA’s sailing research vessels since the early 1980s, SEA’s Plastics Lab is dedicated to investigating and ultimately preventing ocean plastic pollution through collaborative scientific research and broad knowledge sharing.
Marine pollution has been a focus of SEA student research since the early 1980s. Tar balls and plastic particles have been collected and counted in routine, twice-daily plankton net tows at the ocean surface, resulting in long-term records of contamination in the North Atlantic Ocean, Caribbean Sea, and North and South Pacific Oceans. During this time, the occurrence of floating tar balls has substantially declined in the Atlantic Ocean and Caribbean Sea, in contrast to floating plastic debris, which continues to persist. Ocean plastics are the focus of multiple avenues of research by SEA faculty and SEA students to better understand their sources, distribution, transport, and fate.
SEA’s Plastics Lab is committed to communicating the state of scientific knowledge on global plastic pollution to broad audiences, including decision makers, innovators, educators, and inspired community members of all ages who propel the multitude of actions required to address this environmental issue.

Plastics at SEA: 2010 and 2012 Expedition Videos
“It’s an historic day…unfortunately.”
The mid-cruise update from the Plastics at SEA: North Atlantic Expedition in 2010 describes a record number of plastic particles observed by SEA students and scientists in decades of sampling plastic marine debris in the Atlantic Ocean.
Education and Outreach: Bringing the Gyre to the People
Learn how the crew of the Plastics at SEA: North Pacific Expedition 2012 work to bring the experience of sailing in the North Pacific subtropical gyre, and observing and measuring floating plastic debris to public, school, and museum audiences onshore.

Kara Lavender Law, PhD
Research Professor of Oceanography
Kara joined the SEA faculty in 2003 to teach, oversee undergraduate research, and sail as Chief Scientist in SEA Semester programs, including in the regions dubbed “garbage patches” in the eastern North Pacific and western North Atlantic Oceans. For more than 15 years, she has researched plastic debris in the ocean, initially focusing on the physical processes that carry, transport and transform plastics in the marine environment, with more recent work focused “upstream” on the generation, pathways and treatment of plastic waste, ultimately aiming to prevent plastic leakage to the environment. Dr. Law received her Ph.D. from Scripps Institution of Oceanography/University of California, San Diego in physical oceanography, and a B.S. in mathematics from Duke University.

Jessica Donohue, MS
Research Associate
Jessica joined the SEA plastics team in 2014. She is interested in studying how plastics move and change in the marine environment along with sharing information about ocean plastics through education and outreach. She holds a B.S. in environmental geology from Binghamton University, an M.S. from the University of Rhode Island in environmental science/hydrogeology and has a background in science education and outreach.
