The study is based on CTD and water sampling in the Eurasian Basin of the Arctic Ocean in August–September 2012. The research icebreaker Oden and a helicopter were platforms for the sampling. We here report data for inorganic and organic bound nutrient (NO 3 − , NO 2 − , NH 4 + , PO 4 3− , Si(OH) 4 , DON, DOP) concentrations and chlorophyll a between 10 m and 200 m at 29 stations and down to about 4500 m at 13 stations. The data set also includes below sea ice samples (1-2 m) sampling at 31 stations. A total number of 15 different water masses were identified, and their N:P relationship showed that 13 of these clearly originated from the Atlantic Ocean.
