In situ and ex situ oxygen profiles and resulting diffusive oxygen uptake; in situ and ex situ total oxygen flux; benthic community density and biomass, bioturbation potential and solute exchange in the Hausgarten area, Arctic Fram Strait (2014/2015)

During PS85 (in 2014) and PS93.2 (in 2015) sediment cores were recovered by a Multiple corer. Sediment cores were stored at in situ temperature of -0.75°C and used to determine diffusive and total oxygen fluxes, benthic community densities, the bioturbation potential and the solute exchange. Further, autonomous benthic lander was deployed at the HAUSGARTEN stations HG I and HG IV and used to determine also diffusive and total oxygen fluxes and benthic community densities and biomass.
