Summary: | These data describe the biomass (µg C/liter) and abundance (cells/liter) of Synechococcus and small eukaryotes (<20 µm), derived from samples collected in spring and summer 2018 and 2019 in the northern Gulf of Alaska along the Seward Line, in western Prince William Sound, the Middleton Island region, and from a transect extending offshore from NE Kodiak Island. Each individual cell was measured and broken down into size categories (0-2.5, 2.5-5, 5-10, 10-15, 15-20 µm) and further classified as to trophic status, i.e. heterotrophic (lacking chlorophyll) or autotrophic (containing chlorophyll). There are 8 datasheets included, one sheet for abundance and another for biomass from each of four cruises. Data for Synechococcus, autotrophs and heterotrophs are presented separately (in size increments), as total biomass and abundance of each trophic categoty. Excel spreadsheets were converted to CSV files for preservation. These data are an outcome of from NPRB Core Project 1701.
