Floating microplastics concentration collected from MV Maersk Launcher, MV Maersk Transporter, and RV Professor Kaganovskiy in the eastern North Pacific Ocean from 2015-07-25 to 2019-12-09 (NCEI Accession 0276264)

This study was carried out to estimate the floating microplastics (plastics from size 0.5mm to 5mm, reported in unit of pieces/m^3) concentration in the North Pacific Ocean. Microplastics data was collected from 2015-07-25 to 2019-12-09 aboard MV Maersk Launcher, MV Maersk Transporter, and RV Professor Kaganovskiy, using manta and neuston nets. This dataset contains the results from all 663 sampling efforts, in a spreadsheet format.
