This dataset consists of microzooplankton biomass measurements obtained during NGA-LTER research cruises conducted in the Gulf of Alaska during spring, summer and fall, starting in 2018. The data were collected to determine whether microzooplankton abundance and composition varies with time (season) and location. Included in this dataset are measurements of microzooplankton biomass in micrograms Carbon per liter (µg C/L) and abundance in cells per liter (cells/L). Specific categories of microzooplankton measured in this dataset include: oligotrich ciliates (in size increments), Laboea, tintinnids, Gyrodinium and Gymnodinium-like dinoflagellates (in size increments), Protoperidinium-like dinoflagellates, silicoflagellates, as well as the total ciliate, total dinoflagellate, and overall total microzooplankton per sample at various water depths. Excel spreadsheets were converted to CSV files for preservation. These data are part of the Northern Gulf of Alaska Long Term Ecological Research (NGA LTER) program. The LTER program is a National Science Foundation–funded network of 28 sites nationwide that focus on the influence of long-term and large-scale phenomenon on ecosystems. Additional funding for sampling is provided by the North Pacific Research Board (NPRB), the Alaska Ocean Observing System (AOOS), and the Exxon Valdez Oil Spill Trustee Council (EVOS) via the Gulf Watch Alaska program.
