Dissolved organic carbon concentrations from research cruises for the Northern Gulf of Alaska (NGA) LTER site, 2018-2019

This dataset consists of dissolved organic carbon (DOC) concentrations (µmoles/L) obtained during NGA-LTER research cruises conducted in the Gulf of Alaska during spring, summer, and fall of 2018 and 2019. Water samples were collected at surface, 10, 20, 30, 40, 50 and 75 and 150 meters along the Seward Line. The data were collected to determine whether DOC concentration varies with time (season), location and depth. 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.
