Marine Geological Cruise to Storfjordrenna and Bjørnøyrenna aboard R/V Helmer Hanssen

Chief Scientist: Karin Andreassen


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 outer Storfjordrenna and central Bjørnøyrenna. More specific objectives were:

  • Sampling benthic seabed fauna in areas of gas venting to investigate the biological responses to natural gas seeping
  • Mapping seafloor geomorphology and subseabed structures relations to gas venting
  • Mapping seafloor imprints of deglaciation
