Macro-nutrients data set from Expedition PS131, ATWAICE

Here we present a fully quality controlled macro-nutrient data set from analyses carried out onboard the RV Polarstern during the expedition PS131 ATlantic WAter pathways to the ICE in the Nansen Basin and Fram Strait (ATWAICE). The expedition took place from 27 June to 17 August 2022, starting and ending in Bremerhaven, Germany. Analyses of nitrate plus nitrite, nitrite, phosphate, silicate, total nitrogen and total phosphorus were carried out using a Seal Analytical AA500 segmented continuous flow nutrient autoanalyser as part of the Pelagic Biogeochemistry (Nutrients and net community production) Team activities (Grant-No AWI_PS131_06). The rationale as well as details of sampling and analysis can be found in the associated cruise report (https://doi.org/10.57738/BzPM_0770_2023).
