Estimations of floating microplastics, mesoplastics, and macroplastics around Kuroshio Current, western North Pacific collected from 2014-02-03 to 2014-03-01 (NCEI Accession 0279325)

공공데이터포털

This study estimated the concentration of floating microplastics (i.e. plastics measuring less than 5 mm; reported in unit of counts/km2), mesoplastics (i.e. plastics measuring 5-25 mm; reported in unit of counts/km2), and macroplastics (i.e. plastics measuring greater than 25 mm; reported in unit of counts/km2) around Kuroshio Current, western North Pacific collected from 2014-02-03 to 2014-03-01. These plastics in the surface water were collected using a neuston net (450 µm mesh size) by horizontally towing the net over the sea surface for 10 min at a ship speed of approximately three knots at each station. This dataset contains the results from all 132 surface water samples, in a spreadsheet format.

Marine microplastics concentrations in waters around Australia from 2011-06-10 to 2012-08-25 (NCEI Accession 0252260)

공공데이터포털

This study estimated the concentration of marine plastics in waters around Australia using surface Neuston and Manta net tows. Data was collected during seven transit voyages aboard Australian vessels. The study undertook three consecutive 15-minute net tows at 57 locations. The 839 marine plastics recorded during the study were predominantly small fragments (i.e. ‘‘microplastics’’, median length = 2.8 mm, mean length = 4.9 mm) resulting from the breakdown of larger objects made of polyethylene and polypropylene (e.g. packaging and fishing items).
