Here we present dissolved nutrient data collected during Expedition 19S to the Arctic Ocean during September 2018 on board the R/V Sikuliaq, a research vessel operated by the University of Alaska. Data were generated within the framework of the NERC-BMBF Changing Arctic Ocean programme; project Primary productivity driven by escalating Arctic nutrient fluxes? (PEANUTS) in collaboration with the US Office of Naval Research Stratified Ocean Dynamics of the Arctic programme (SODA). A report is included, which provides further details about the data, funding agencies and research for which these data has been used.
