Samples for sediment porosity on the Northeast Greenland shelf have been collected with R/V Polarstern during PS109 between September and October 2017 using a camera-equipped multiple corer (TV-MUC; core area 0.007 m²). Upon arrival on deck, the upper 5 cm of three MUC cores were sliced into 1 cm intervals, using a cut-off syringe in order to get a depth resolution of the sediment porosity, and then stored in 5 ml cut-off syringes that were wrapped in aluminium foil. In the laboratory, the samples were sliced into 1 cm intervals. After measuring their wet mass, the sediment samples were dried at 60°C. The sediment porosity was calculated by the difference between the wet and dry mass after Dalsgaard et al., 2000.
