Nutrient and Oxygen Chemistry Data from the R/V TINRO during the 2022 International Year of the Salmon Pan-Pacific Winter High Seas Expedition

Water sample collections were conducted using 12-position rosette equipped with a SeaBird CTD 911 plus to a depth of 1000 m. Nutrient and dissolved oxygen samples were collected from 0-5, 25, 50, 75, 100, 150, 200, 400, 600, and 1000 m. Rosette had a capacity to carry ten 5L and two 1,8L Niskin Bottles. Bottle firing was operated remotely using Carousel Deck Unit model 33 and real-time tracking system Sea Bird Electronics model 25. Chlorophyll-a, dissolved Oxygen and dissolved nutrient samples (silicates, dissolved inorganic phosphate, nitrites, nitrates) were processed on board according to methods listed in the cruise plan (Pakhomov et al., 2021). These data were collected in the North Pacific ocean as part of the 2022 Pan Pacific Winter High Seas Expedition surveying the salmon ecosystem as part of the International Year of the Salmon.
