Most data on microplastic concentrations comes from commercial and research ships that tow plankton nets—long, cone-shaped nets with very fine mesh designed for collecting marine microorganisms. But net trawling can sample only small areas and may be underestimating true plastic concentrations. Except in the North Atlantic and North Pacific gyres—large zones where ocean currents rotate, Read more about Using satellites to track tiny plastic particles and their concentration in the ocean[…]
