Station map superimposed on the sea surface temperature across the Baltic Sea during RV Meteor cruise M117 in July/August 2015. Biogeochemical variables were taken at 14 stations (marked in white), of which 11 contained all 124 variables for a detailed multivariate analysis including three upwelling stations off Öland (UP2‐UP4), two upwelling stations in the Gulf of Finland (UP5 and UP6), one western Baltic Sea station (TF12), and five central Baltic Sea stations (TF113, TF109, TF213, TF259, and TF271).
