The Baltic Sea has been affected by eutrophication for several decades with the result of a gradual increase of oxygen minimum zones at the sea floor and release of phosphate...

The data originates from 23 drilling stations sampled in the Canadian Beaufort Sea in September and October 2021 as part of the PeCaBeau2021 (Permafrost Carbon on the Beaufort...

C, N and S analysed with a CNS elemental analyser (EuroEA, Eurovector). Biogenic silica was measured following the leaching method of Müller & Schneider (1993,...

Effects of changed levels of dissolved O2 and CO2 on marine primary producers are of general concern with respect to ecological effects of ongoing ocean deoxygenation and...

This dataset contains abiotic and biotic data from sediment samples from four sites in the northwestern Weddell Sea. Data are provided for sediment pigments (chlorophyll a and...

Palmitic acid (PA) is ubiquitous in the biosphere and its hydrogen isotopic composition (δ2HPA) was proposed as a potential paleoenvironmental proxy for salinity, with δ2HPA...

Phaeodactylum tricornutum strain CCAP 1052/1A was cultivated at 6°C and 15°C under controlled conditions (32 salinity, F/2 medium, 400 µatm pCO2, 100 µmol photons m-2 s-2 light...

Sea ice retreat, changing stratification, and ocean acidification are fundamentally changing the light availability and physico-chemical conditions for primary producers in the...
