Dissolved inorganic nutrient data from stations sampled on NGA-LTER seasonal cruises, 2018-2022

This dataset contains annual inorganic macronutrient data from stations sampled on NGA LTER seasonal cruises along cross-shelf lines and in Prince William Sound. Samples were collected during spring, summer and fall cruises from the regular CTD rosette bottles triggered at set depths, from the surface to a maximum depth of 1000 or 1500 meters, depending on the ship used. Specific nutrients measured include nitrate plus nitrite, silicic acid (silicate), and phosphate, with concentrations reported in micromoles per liter (micromolar). The data file format is an annual csv file made from concatenating files from each seasonal cruise. 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.
