CAGE20-8 cruise onboard RV “Kronprins Haakon” aimed to survey the natural seepage of methane along the NE Greenland margin. Based on multibeam echosounder surveys, water column mapping for gas flares, and shallow seismic, gravity coring and multicoring were conducted. Due to heavy ice conditions, the vessel did not reach the shelf, however, survey along the continental slope were conducted. From a number of acoustic profiles and sediment cores, we will pursue the investigations of natural seepage related to glacial variability and sea ice fluctuations over the coming months.
The cruise may be known as: CAGE20_8
