Ex situ diffusive oxygen uptake of the Northeast Greenland (NEG) shelf sediments from POLARSTERN cruise PS109 ...
Ex situ diffusive oxygen uptake (DOU) at the sediment water interface was assessed on the Northeast Greenland shelf 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, part of the overlying wat...
