Assimilation of heterogeneous measurements at different spatial scales in the Arctic ocean and Norwegian sea
Halvorsen, Daniel Ørnes; Dallolio, Alberto; Alver, Morten Omholt (Chapter, 2022)The assimilation of ocean temperature measurements into ocean models provides useful insights on how to design heterogeneous ocean observation systems. In systems of this kind, ocean models can be complemented with multiscale ... -
Campaign For Hyperspectral Data Validation In North Atlantic Coastal Waters
Oudijk, Esmée; Hasler, Oliver Kevin; Overaas, H; Marty, Sabine; Williamson, David; Svendsen, T; Berg, Simen; Birkeland, Roger; Halvorsen, D; Bakken, S; Henriksen, Marie Bøe; Alver, Morten; Johnsen, Geir; Johansen, Tor Arne; Stahl, Annette; Kvaløy, Pål; Dallolio, Alberto; Majaneva, Sanna; Fragoso, Glaucia Moreira; Garrett, Joseph (Peer reviewed; Journal article, 2022)The high photosynthetic productivity of the Mausund bank on the coast of mid-Norway has given the area important economic and ecologic value. Monitoring chlorophyll-a (chl-a) production can assist in managing the local ... -
Design and development of a robotic fish tracking vehicle
Lauvås, Nikolai (Master thesis, 2020)Posisjonering av akustiske fiskemerker (tags) over tid er ønsket til bruksområder som å spore fiskers vandring gjennom fjorder. Bruken av autonome fartøy utstyrt med akustiske mottakere har i de senere årene dukket opp i ... -
Design and experimental validation of a control architecture for a wave-propelled USV: From system design to ocean studies
Dallolio, Alberto (Doctoral theses at NTNU;2022:42, Doctoral thesis, 2022)In a time of unprecedented anthropogenic pressures on the oceans, preserving the health of underwater ecosystems is of the uttermost importance. Since the beginning of human exploration of the oceans, ship-based ocean ... -
Design and Validation of a Course Control System for a Wave-Propelled Unmanned Surface Vehicle
Dallolio, Alberto; Øveraas, Henning; Alfredsen, Jo Arve; Fossen, Thor Inge; Johansen, Tor Arne (Journal article, 2022)Unlike common marine vessels, wave-propelled vehicles cannot directly control their speed, but rely instead on the forces exerted by the environment to navigate as intended. The unique navigation capabilities of such ... -
ENC-based Anti-Grounding and Anti-Collision System for a Wave-Propelled USV
Dallolio, Alberto; Bergh, Thea; De La Torre, Pedro R.; Øveraas, Henning; Johansen, Tor Arne (Chapter, 2022)Wave-propelled unmanned surface vehicles (USVs) rely on the forces exerted by the environment to navigate as intended. The unpredictability of the environment and the low speed and limited maneuverability that characterizes ... -
ENC-based Collision and Grounding Avoidance System for a Green-Energy Autonomous Surface Vehicle
Bergh, Thea Kristine (Master thesis, 2021)Autonome overflatefartøy (ASV-er) kan spille en viktig rolle i utviklingen av systemer som utforsker og observerer havet på en bærekraftig og kontinuerlig måte, selv i avsidesliggende områder og under tøffe forhold. Disse ... -
Gain-scheduled steering control for a wave-propelled unmanned surface vehicle
Dallolio, Alberto; Øveraas, Henning; Johansen, Tor Arne (Peer reviewed; Journal article, 2022)The persistent observation of oceanographic phenomena is nowadays hampered by technological limitations, that prevent marine robotic platforms to autonomously execute scientific surveys for extended periods of time. The ... -
Mission Planning for Wave Driven Autonomous Surface Vessels
Skaar, Sindre Løining (Master thesis, 2020)En økt bruk av autonome sjøfarende fartøy er forventet å drastisk forandre hvordan både mennesker, gods og forskning blir håndtert i fremtiden. Den økte kapabiliteten til autonome fartøy har gjort dem til et mer aktuelt ... -
