Abstract

The cruise visited several areas in Hopendjupet, and Sentralbankrenna in the central Barents Sea, and had the following scientific objectives:

  • Surveying and sampling of gas seepage associated with known and assumed sandstone reservoirs sub-cropping at the sea floor due to erosion of overlying cap rocks in Hopendjupet and Sentralbanken
  • Surveying and sampling of gas seepage related to leakage along faults and geological structures breaching the seafloor in Hopendjupet and Sentralbanken
  • Sampling of oil in sea surface slicks and within shallow sediment cores
  • Surveying of landforms associated with the retreat of the Barents Sea Ice Sheet in the outer Sentralbankrenna area

The cruise may be known as: CAGE21_4
