Particulate carbon concentrations from research cruises for the Northern Gulf of Alaska (NGA) LTER site, 2018-present

This dataset consists of particulate carbon concentrations 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 particulate carbon concentration varies with time (season), location and depth. Total particulate carbon (TPC), particulate organic carbon (POC) and particulate inorganic carbon (PIC) concentrations at 4 depths (10, 30, 50, 75 meters in spring; 0, 10, 20, 40 meters in summer and fall) were calculated. 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.
