Description: The sampling campaigns were conducted in the Black Sea (POS539), Baltic Sea/Gotland Basin (EMB324), and on a boat in Denmark/Mariager Fjord. All three study sites are differently influenced by ocean deoxygenation and anoxia. While Mariager Fjord waters are seasonally anoxic, the deep waters of Gotland Basin and Black Sea can remain anoxic for decades and millennia, respectively. Furthermore, to target potential abiotic reactions, we incubated filtered Gotland Basin waters at low (<1.5µM O2) and high (>200µM O2) oxygen concentrations. All samples were filtered to 0.2 µm pore size and acidified with hydrochloric acid to pH2. DOM was extracted and desalted prior to molecular analysis with ultrahigh resolution mass spectrometry (FT-ICR-MS) following an established method using cartridges filled with a styrene-divinylbenzene copolymer (Agilent Bond Elut PPL, 1 g). This data set contains two files: (1) environmental data, including oxygen concentrations, salinity, temperature, dissolved and solid-phase extractable dissolved carbon (DOC, SPE-DOC), nitrogen (TDN, SPE-DON), sulfur (SPE-DOS), and phosphorus (SPE-DOP), and (2) processed FT-ICR-MS data for all samples.
