      Thorsnes, Terje; Chand, Shyam; Bellec, Valerie Karin; Nixon, Chantel; Brunstad, Harald; Lepland, Aivo; Aarrestad, Sigrun M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-01)
      Gas seeps and fluid-flow related seabed features are found over the entire Norwegian exclusive economic zone (EEZ). Multibeam water-column data from c. 136 000 km2 has revealed more than 5 000 gas seeps. Most of the gas seeps seem to have biogenic, thermogenic or mixed origin; some may be of abiotic origin. The spatial distribution of the gas seeps appears to correlate with: 1 – structural highs ...

      We discovered seafloor features such as bacterial mats and carbonate crusts typical for active methane seeps on the continental slope southwest of Svalbard. These features are associated with two main northwest-southeast trending morphological structures that are oriented parallel to the regional continental slope. Both structures occur at c. 800 m water depth, at the boundary between the Storfjorden ...
