2Abstract
The cruise aimed at investigating areas with gas venting from the seabed in central Bjørnøyrenna and outer Storfjordrenna, as well as subglacial meltwater systems in Thor Iversenbanken, central Barents Sea. More specific objectives included: acquisition of a P-cable 3D seismic survey over part of a large crater and pingo field in central Bjørnøyrenna, sampling gas in water, sediments and air in areas of gas venting within the crater and pingo field, acquisition of gravity cores for identification of palaeo-subglacial lakes in Thor Iversenbanken, acquisition of 2D seismic across subglacial meltwater systems in Thor Iversenbanken, acquisition of 2D seismic across pingos identified in Storfjordrenna, and sampling of gas in air in the area where pingos have been identified in Storfjordrenna.URL
