Abstract

These data include transparent exopolymer particle (TEP) and Coomassie stainable particle (CSP) concentrations within the upper 500 meters collected on a 12-day June 2021 cruise aboard the R/V Kilo Moana (KM2108) that visited Station ALOHA to 31 N nominally along 158 W in the subtropical North Pacific. Particle concentrations are measured spectrophotometrically using Alcian blue (TEP) and Coomassie blue (CSP) dyes and reported in the semi-quantitative concentration units of xanthan gum equivalen...
