Profiles of nitrate and nitrite and silicic acid during PS138 (ArcWatch 1) to the Central Arctic Ocean (NutrientProfiles)

DOI

This data was collected during the Polarstern cruise PS138 (ArcWatch1) from August 3 to September 30, 2023 to the Central Arctic Ocean. During the Polarstern cruise PS138 (ArcWatch1) we sampled a total of 9 ice stations and a transect of oceanographic station from the North Pole along 60°E. At each station samples for inorganic nutrient analysis were taken between the surface and 200m with a CTD rosette. Samples for nitrate and silicic acid were analysed onboard using a continuous flow autoanalyser (AA500, SEAL Analytical, Norderstedt, Germany).
