Benthic biogeochemical parameters measured during Polarstern expedition PS94 (TransArcII) to the Barents Sea and central Arctic

During the RV Polarstern expedition PS94, we gathered sediment samples in the Barents Sea and the central Arctic Ocean by deploying both a multiple corer (MUC) and a giant boxcorer (GKG). After retrieval of the MUC or GKG, replicate sediment cores with a visibly intact sediment surface were chosen f...

Description
Summary:During the RV Polarstern expedition PS94, we gathered sediment samples in the Barents Sea and the central Arctic Ocean by deploying both a multiple corer (MUC) and a giant boxcorer (GKG). After retrieval of the MUC or GKG, replicate sediment cores with a visibly intact sediment surface were chosen for further laboratory analysis. The selected cores were brought to the laboratory on board RV Polarstern for further analysis. While data on chlorophyll pigments, total organic carbon, microbial cell numbers and diffusive oxygen uptake rates were taken from the same cores, total oxygen uptake rates were measured in three additional cores.
