15-Year Study Indicates Huge Increase in Pacific Ocean Microplastics

Charles Moore, who first sailed the so-called Great Pacific Garbage Patch in 1997, has returned five times over 15 years to document the concentrations of plastic in the ocean. His results show microplastics are accumulating at a rapid rate.

In 1997, sailboat captain Charles Moore sailed from Hawaii across the Pacific Ocean, taking a shortcut to his home port of Los Angeles after a sailing race. As he cut across the then-seldom-sailed stretch of ocean – the swirling North Pacific Gyre – he came upon an enormous accumulation of plastic trash and made it famous. He helped captured the public’s imagination around the problem of marine plastic pollution by writing about the “Great Pacific Garbage Patch.”

On Monday, two decades after his discovery, he reported a seemingly dramatic 60-fold increase in the tiny pieces of microplastic during his 15 years of study of the now-infamous ocean area. From 1999 to 2014, he and a team of researchers regularly returned to 11 sites across this area with Algalita, the nonprofit he founded, scooping up plastic samples using a manta trawl from Moore’s research catamaran in an attempt to quantify change in plastic over time.
