Abstract:
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).
