Microplastics concentration collected from R/V New Horizon and NOAA Ship Okeanos Explorer in Northeast Pacific Ocean from 1972-04-25 to 2010-10-28 (NCEI Accession 0253448)

This dataset quantifies the distribution, and abundance of microplastics in the northeastern Pacific. Data was collected aboard R/V New Horizon and NOAA Ship Okeanos Explorer using neuston and manta nets and is in a spreadsheet format. This dataset includes the results from 235 tows, collected under different programs over 38 years. The ships traveled at about 18.5 km/hr, with tows spaced approximately 74-111 km apart. Mean concentration of microplastics for the dataset is 2.18 particles/m3.
