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 aim of the cruise was to visit two study areas: the first a new study site called Maud Basin in southern Bjørnøyrenna – an area where industry data has shown promising evidence for gas leakage associated with pingo/crater formation and an underlying hydrocarbon reservoir. The second site is the Crater Area previously visited by CAGE in 2015 (15-5). More specific objectives of the cruise were to: Obtain multibeam and seismic lines over pingos and craters in Maud Basin, southern Bjørnøyrenna, already identified on industry seismic dataRe-examine the high density flares areas of the Crater Area previously surveyed in 2015 for any changesSurvey new areas in the surrounding region of the Crater AreaObtain plankton net data from gas leaking sites for analyses of biomass The cruise may be known as: CAGE16_2
