(2000), Comment, Date/Time of event, Depth, bottom/max, sediment/rock, top/min, Elevation of event, Event label, FRAM, FRontiers in Arctic marine Monitoring, Latitude of event, Longitude of event, Method/Device of event, Multicorer with television, Polarstern, Porosity, PS109, PS109_105-1, PS109_115-3, PS109_125-3, PS109_129-1, PS109_139-4, PS109_154-2, PS109_19-4, PS109_36-3, PS109_45-3, PS109_61-1
Subject Geographic: MEDIAN LATITUDE: 78.774547 * MEDIAN LONGITUDE: -14.939610 * SOUTH-BOUND LATITUDE: 76.486370 * WEST-BOUND LONGITUDE: -19.321920 * NORTH-BOUND LATITUDE: 80.312990 * EAST-BOUND LONGITUDE: -7.109350 * DATE/TIME START: 2017-09-17T15:16:00 * DATE/TIME END: 2017-10-07T03:28:00 * MINIMUM DEPTH, sediment/rock: 0.0025 m * MAXIMUM DEPTH, sediment/rock: 0.1900 m
Description: 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.
