Inorganic Carbon data from water samples collected during CTD casts at stations during the Northern Gulf of Alaska LTER seasonal cruises, 2018-2020

This dataset contains analyses of dissolved inorganic carbon (DIC), total alkalinity (TA), and pH from water samples collected during the Northern Gulf of Alaska LTER Spring, Summer, and Fall cruises from 2018-2020. Water samples were collected from niskin bottles on a rosette used during CTD casts at stations on each cruise. Data from Spring and Summer 2018 also contain pCO2 values. 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.
