On July 7, 2017, at 11:30 a.m. EDT (1530 UTC), the Moderate Resolution Imaging Spectroradiometer, or MODIS, instrument aboard NASA's Terra satellite captured a visible image of Tropical Depression 4 as it continued moving through the north Central Atlantic Ocean.

As the infamous floating “garbage patch” churns up bits of plastic in the tropical Pacific Ocean, a University of Washington undergraduate has discovered a related problem much closer to home: nearly invisible bits of plastic on Puget Sound beaches.
