    • Coastal permafrost was massively eroded during the Bølling-Allerød warm period 

      Nogarotto, Alessio; Noormets, Riko; Chauhan, Teena; Mollenhauer, Gesine; Hefter, Jens; Grotheer, Hendrik; Belt, Simon T.; Colleoni, Florence; Muschitiello, Francesco; Capotondi, Lucilla; Pellegrini, Claudio; Tesi, Tommaso (Journal article; Peer reviewed, 2023)
      The Bølling-Allerød interstadial (14,700–12,900 years before present), during the last deglaciation, was characterized by rapid warming and sea level rise. Yet, the response of the Arctic terrestrial cryosphere during this ...

    • Fluid migration pathways to seafloor seepage in inner Isfjorden and Adventfjorden, Svalbard 

      Roy, Srikumar; Senger, Kim; Braathen, Alvar; Noormets, Riko; Hovland, Martin; Olaussen, Snorre (Peer reviewed; Journal article, 2014)
      This study represents a marine baseline study for the Longyearbyen CO2 Lab, in which CO2 may be injected in the Upper Triassic–Middle Jurassic Kapp Toscana Group, which comprises several permeable beds. The target ...

    • Geometries of doleritic intrusions in central Spitsbergen, Svalbard: an integrated study of an onshore-offshore magmatic province with implications for CO2 sequestration 

      Senger, Kim; Roy, Srikumar; Braathen, Alvar; Buckley, Simon John; Bælum, Karoline; Gernigon, Laurent; Mjelde, Rolf; Noormets, Riko; Ogata, Kei; Olaussen, Snorre; Planke, Sverre; Ruud, Bent Ole; Tveranger, Jan (Peer reviewed; Journal article, 2013)
      Igneous intrusions emplaced during the Early Cretaceous are well exposed in central Spitsbergen within the Permian–Jurassic sedimentary succession. The doleritic intrusions are collectively classified as the Diabasodden ...

    • Seasonal sea ice persisted through the Holocene Thermal Maximum at 80°N 

      Pieńkowski, Anna J.; Husum, Katrine; Belt, Simon T.; Ninnemann, Ulysses S; Köseoğlu, Denizcan; Divine, Dmitry V.; Smik, Lukas; Knies, Jochen; Hogan, Kelly; Noormets, Riko (Journal article; Peer reviewed, 2021)
      The cryospheric response to climatic warming responsible for recent Arctic sea ice decline can be elucidated using marine geological archives which offer an important long-term perspective. The Holocene Thermal Maximum, ...
