SeaFlow data v1: High-resolution abundance, size and biomass of small phytoplankton in the North Pacific

The data set consists of SeaFlow-based cell abundance, cell size (equivalent spherical diameter), cellular carbon content and total carbon biomass for picophytoplankton populations, namely the cyanobacteria Prochlorococcus, Synechococcus and small-sized Crocosphaera (2-5 um), and picoeukayotes phytoplankton and nanophytoplankton (2-5 μm ESD). SeaFlow is an underway flow cytometer that provides continuous shipboard observations of the optical properties of the smallest phytoplankton. The instrument collects the equivalent of 1 sample every 3 minutes or every 1 km (for a ship moving at 10 knots) from the ship’s flow-through seawater system. Since 2010, the instrument has been operated for 14,000 hours across 140,000 km of ocean, collecting over 300,000 samples in surface waters.
