Salinity from discrete water samples collected from the Research Vessel Sikuliaq, Gulf of Alaska to Bering Sea, 2023

This data set includes measurements of water samples collected at hydrographic stations from the 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 salinity (this data set). Specifically, this data set contains conductivity, temperature, and depth (CTD) measurements of salinity at discrete water depths and portasal measurements of water samples from the corresponding bottles. Bottle samples were collected in 200 milliliter (mL) borosilicate bottles which were rinsed at least three times before filling. The bottles were sealed with Nalgene screw caps and stored without freezing.
