The distribution, abundance, and characteristics of neuston plastic in the North Pacific, Bering Sea, and Japan Sea were studied during the 4-year period 1985-88 at 203 neuston stations encompassing ca. 91,000 m2 of sampling. The highest total density of neuston plastic was 316,800 pieces/km2 at lat...
