Formation of a large submarine crack during the final stage of retrogressive mass wasting on the continental slope offshore northern Norway
Laberg, Jan Sverre; Baeten, Nicole Jeanne; Lågstad, Petter Arthur; Forwick, Matthias; Vorren, Tore Ola (2013)High-resolution swath-bathymetry data integrated with sub-bottom profiles and single-channel seismics reveal an 18 km long, up to 1000 m wide and 10–15 m deep crack located approx. 4 km upslope from a slide scar on the ... -
Multiple episodes of fluid flow in the SW Barents Sea (Loppa High) evidenced by gas flares, pockmarks and gas hydrate accumulation
Chand, Shyam; Thorsnes, Terje; Rise, Leif; Brunstad, Harald; Stoddart, Daniel; Bøe, Reidulv; Lågstad, Petter Arthur; Svolsbru, Torgeir (2012)Gas and gas hydrates have gained considerable attention in the last 20 yr due to their possible impact on global climate change from methane escalations. Our study area, the SW Barents Sea, is unique in its evolution due ... -
On the use of the HUGIN 1000 HUS Autonomous Underwater Vehicle for high resolution zooplankton measurements
Pedersen, Ole Petter; Gaardsted, Frank; Lågstad, Petter Arthur; Tande, Kurt Steinar (2010)This paper evaluates and tests the HUGIN 1000 HUS AUV as a carrier platform for the Laser Optical Plankton Counter (LOPC). The LOPC was mounted outside on top of the carrier platform, and the tests confirm that this concept ... -
Strategy for Detection and High-Resolution Characterization of Authigenic Carbonate Cold Seep Habitats Using Ships and Autonomous Underwater Vehicles on Glacially Influenced Terrain
Thorsnes, Terje; Chand, Shyam; Brunstad, Harald; Lepland, Aivo; Lågstad, Petter Arthur (2019-11-26)Cold seep habitats with authigenic carbonates and associated chemosynthetic communities in glacially influenced terrains constitute an important part of the benthic ecosystems, but they are difficult to detect in large-scale ...
