In an exploration of the 'great Pacific Ocean garbage patch', scientists from the Scripps Environmental Accumulation of Plastic Expedition (SEAPLEX) have discovered extensive plastic debris floating 1,000 miles from land.
The Scripps research vessel (R/V) New Horizon left its San Diego homeport on August 2, 2009, for the North Pacific Ocean Gyre, located some 1,000 miles off California's coast, and returned on August 21, 2009.
Scientists surveyed plastic distribution and abundance, taking samples for analysis in the lab and assessing the impacts of debris on marine life.
Before this research, little was known about the size of the "garbage patch" and the threats it poses to marine life and the gyre's biological environment.
The expedition was led by a team of Scripps Institution of Oceanography (SIO) graduate students, with support from University of California Ship Funds, the National Science Foundation (NSF) and Project Kaisei.
"SEAPLEX was an important education experience for the graduate students, and contributed to a better understanding of an important problem in the oceans," said Linda Goad, program director in NSF's Division of Ocean Sciences.
