The cruise was a part of the Centre of Excellence for Gas Hydrate, Environment and Climate (CAGE) at UiT – The Arctic University of Norway. 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: Acquisiton of a P-cable 3D seismic survey over part of a large crater and pingo field in central BjørnøyrennaSampling gas in water, sediments and air in areas of gas venting within the crater and pingo fieldAcquisiton of gravity cores for identification of palaeo-subglacial lakes in Thor IversenbankenAcquisiton of 2D seismic across subglacial meltwater systems in Thor IversenbankenAcqusition of 2D seismic across pingos identified in StorfjordrennaSampling of gas in air in the area where pingos have been identified in Storfjordrenna The cruise may be known as: CAGE15_5
