    • Consistent ice and open water classification combining historical synthetic aperture radar satellite images from ERS-1/2, Envisat ASAR, RADARSAT-2 and Sentinel-1A/B 

      Johansson, Malin; Malnes, Eirik; Gerland, Sebastian; Cristea, Anca; Doulgeris, Anthony Paul; Divine, Dmitry V; Pavlova, Olga; Lauknes, Tom Rune (Peer reviewed; Journal article, 2019)
      Synthetic Aperture Radar (SAR) satellite images are used to monitor Arctic sea ice, with systematic data records dating back to 1991. We propose a semi-supervised classification method that separates open water from sea ...

    • Environmental Controls of InSAR-Based Periglacial Ground Dynamics in a Sub-Arctic Landscape 

      Rouyet, Line; Karjalainen, Olli; Niittynen, P.; Aalto, Juha; Luoto, Miska; Lauknes, Tom Rune; Larsen, Yngvar; Hjort, J. (Peer reviewed; Journal article, 2021)
      Periglacial environments are characterized by highly dynamic landscapes. Freezing and thawing lead to ground movement, associated with cryoturbation and solifluction. These processes are sensitive to climate change and ...

    • Multi-agent informed path planning using the probability hypothesis density 

      Olofsson, Harald Lennart Jonatan; Hendeby, Gustaf; Lauknes, Tom Rune; Johansen, Tor Arne (Peer reviewed; Journal article, 2020)
      An Informed Path Planning algorithm for multiple agents is presented. It can be used to efficiently utilize available agents when surveying large areas, when total coverage is unattainable. Internally the algorithm has a ...

    • Permafrost in monitored unstable rock slopes in Norway-New insights from temperature and surface velocity measurements, geophysical surveying, and ground temperature modelling 

      Etzelmüller, Bernd; Czekirda, Justyna; Magnin, Florence; Duvillard, Pierre-Allain; Ravanel, Ludovic; Malet, Emanuelle; Aspaas, Andreas Grøvan; Kristensen, Lene; Skrede, Ingrid; Majala, Gudrun D.; Jacobs, Benjamin; Leinauer, Johannes; Hauck, Christian; Hilbich, Christin; Böhme, Martina; Hermanns, Reginald; Eriksen, Harald Øverli; Lauknes, Tom Rune; Krautblatter, Michael; Westermann, Sebastian (Peer reviewed; Journal article, 2022)
      The warming and subsequent degradation of mountain permafrost within alpine areas represent an important process influencing the stability of steep slopes and rock faces. The unstable and monitored slopes of Mannen (Møre ...

    • Regional Morpho-Kinematic Inventory of Slope Movements in Northern Norway 

      Rouyet, Line; Lilleøren, Karianne Staalesen; Böhme, Martina; Vick, Louise Mary; Delaloye, Reynald; Etzelmüller, Bernd; Lauknes, Tom Rune; Larsen, Yngvar; Blikra, Lars Harald (Peer reviewed; Journal article, 2021)

    • Seasonal InSAR Displacements Documenting the Active Layer Freeze and Thaw Progression in Central-Western Spitsbergen, Svalbard 

      Rouyet, Line; Liu, Lin; Strand, Sarah Marie; Christiansen, Hanne H; Lauknes, Tom Rune; Larsen, Yngvar (Peer reviewed; Journal article, 2021)
      In permafrost areas, the active layer undergoes seasonal frost heave and thaw subsidence caused by ice formation and melting. The amplitude and timing of the ground displacement cycles depend on the climatic and ground ...

    • SIOS’s Earth Observation (EO), Remote Sensing (RS), and operational activities in response to COVID-19 

      Jawak, Shridhar D.; Andersen, Bo N.; Pohjola, Veijo; Godøy, Øystein; Hübner, Christiane E.; Jennings, Inger; Ignatiuk, Dariusz; Holmen, Kim; Sivertsen, Agnar; Hann, Richard; Tømmervik, Hans; Kääb, Andreas; Błaszczyk, Małgorzata; Salzano, Roberto; Luks, Bartłomiej; Høgda, Kjell Arild; Storvold, Rune; Nilsen, Lennart; Salvatori, Rosamaria; Krishnan, Kottekkatu Padinchati; Chatterjee, Sourav; Lorentzen, Dag Arne; Erlandsson, Rasmus; Lauknes, Tom Rune; Malnes, Eirik; Karlsen, Stein Rune; Enomoto, Hiroyuki; Fjæraa, Ann Mari; Zhang, Jie; Marty, Sabine; Nygård, Knut Ove; Lihavainen, Heikki (Journal article; Peer reviewed, 2021)
      Svalbard Integrated Arctic Earth Observing System (SIOS) is an international partnership of research institutions studying the environment and climate in and around Svalbard. SIOS is developing an efficient observing system, ...
