NTNU-FFI Cruise 2017 - Hugin Autonomy Integration (DUNE, T-REX)
Sture, Øystein; Syre Wiig, Martin; Fossum, Trygve Olav (NTNU Cruise reports;, Research report, 2017)The following report describes the integration of a dedicated autonomy co-processor on FFI Hugin HUS. The integration was experimentally validated during a joint FFI-NTNU cruise in November 2017. The cruise in its entirety ... -
Obtaining Hyperspectral Signatures for Seafloor Massive Sulphide Exploration
Sture, Øystein; Snook, Ben; Ludvigsen, Martin (Journal article; Peer reviewed, 2019)Seafloor massive sulphide (SMS) deposits are hosts to a wide range of economic minerals, and may become an important resource in the future. The exploitation of these resources is associated with considerable expenses, and ... -
Recognition of Cold-Water Corals in Synthetic Aperture Sonar Imagery
Sture, Øystein; Ludvigsen, Martin; Scheide, Margrete Sandsbråten; Thorsnes, Terje (Chapter, 2018)The deep-water coral Lophelia pertusa is a common reef-building scleractinian coral, or stony coral, occurring in mid to deep waters around the world. The reefs they form are regarded as hot spots for biodiversity and ... -
Remote Sensing of the Tautra Ridge: An Overview of the World’s Shallowest Cold-Water Coral Reefs
Mogstad, Aksel Alstad; Løvås, Håvard; Sture, Øystein; Johnsen, Geir; Ludvigsen, Martin (Peer reviewed; Journal article, 2022)On the Tautra Ridge – a 39-100 m deep morainic sill located in the middle of the Trondheimsfjord, Norway – some of the world’s shallowest known occurrences of the scleractinian cold-water coral (CWC) Desmophyllum pertusum ... -
Trajectory Planning for Navigation Aiding of Autonomous Underwater Vehicles
Sture, Øystein; Norgren, Petter; Ludvigsen, Martin (Peer reviewed; Journal article, 2020)Autonomous underwater vehicles can perform seabed surveys with a higher resolution and quality than from equivalent ship-mounted sensors.
