    • Adaptive Underwater Robotic Sampling of Dispersal Dynamics in the Coastal Ocean 

      Berget, Gunhild Elisabeth; Eidsvik, Jo; Alver, Morten; Py, Frédéric; Grøtli, Esten Ingar; Johansen, Tor Arne (Chapter, 2022)
      To get a better understanding of the highly nonlinear processes driving the ocean, efficient and informative sampling is critical. By combining robotic sampling with ocean models we are able to choose informative sampling ...

    • Dynamic stochasticmodeling for adaptive sampling of environmental variables using an AUV 

      Berget, Gunhild Elisabeth; Eidsvik, Jo; Alver, Morten Omholt; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)
      Discharge of mine tailings significantly impacts the ecological status of the sea. Methods to efficiently monitor the extent of dispersion is essential to protect sensitive areas. By combining underwater robotic sampling ...

    • Long-Horizon Informative Path Planning with Obstacles and Time Constraints 

      Ge, Yaolin; Olaisen, André Julius Hovd; Eidsvik, Jo; Jain, Ravinder Praveen Kumar; Johansen, Tor Arne (Peer reviewed; Journal article, 2022)
      We apply non-myopic informative path planning in a simulated river plume case study with several constraints on our agent. A cost valley philosophy is proposed to guide the agent through the field. The purpose of this path ...

    • Simultaneous tracking of multiple whales using two fiber-optic cables in the Arctic 

      Rørstadbotnen, Robin Andre; Eidsvik, Jo; Bouffaut, Léa; Landrø, Martin; Potter, John Robert; Taweesintananon, Kittinat; Johansen, Ståle Emil; Storvik, Frode; Jacobsen, Joacim; Schjelderup, Olaf; Wienecke, Susann; Johansen, Tor Arne; Ruud, Bent Ole; Wuestefeld, Andreas; Oye, Volker (Peer reviewed; Journal article, 2023)
      Climate change is impacting the Arctic faster than anywhere else in the world. As a response, ecosystems are rapidly changing. As a result, we can expect rapid shifts in whale migration and habitat use concurrent with ...
