Nutrient data from water samples (surface and depth) collected from the Research Vessel Sikuliaq, Gulf of Alaska to Bering Sea, 2023

This data set includes nutrient measurements of water samples collected at hydrographic stations from the Research Vessel (R/V) Sikuliaq during the Arctic Chief Scientist Training cruise June 6–12, 2023 sponsored by the University National Oceanographic Laboratory System (UNOLS) Arctic Icebreaker Coordinating Committee and the National Science Foundation. SKQ202309T was utilized as a training expedition for early-career Arctic oceanographers, focusing on skills essential for leading research cruises. Training topics centered on logistics, how to request time on ships, how to coordinate personnel and equipment, how to plan for operations and survey tasks at sea, how to work with vessel crew and staff, and how to edit research plans based on field conditions. Participants collected various data sets opportunistically throughout the research training. The cruise transited from Seward to Nome and water samples were collected at six hydrographic stations for nutrients (this data set). Specifically, this data set contains nutrient (total dissolved phosphorus (TDP), total dissolved nitrogen (TDN), phosphate, and nitrate+nitrite) measurements at surface and above seabed water depths. Bottle samples were collected in high-density polyethylene (HDPE) bottles which were rinsed at least three times before filling. The bottles were frozen at -40 Celsius (C).
