Gelatinous zooplankton abundance and wet weight biomass observations from research cruises for the Northern Gulf of Alaska (NGA) LTER site, 2018 - 2022

This dataset presents the distribution, abundance and biomass (wet weight) of the large gelatinous zooplankton (Cnidarians and Ctenophores) obtained from methot net trawls during the NGA-LTER research cruise conducted in the Gulf of Alaska aboard the R/V Wolstad, R/V Tiglax, and R/V Silkuliaq during Spring, Summer, and Fall of 2018 - 2022. Trawls were conducted at night, just below the surface, with a Methot net with a surface area of 5 square meters (10 m long, 3 mm mesh body ). 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.
