    • Long-term analysis of cryoseismic events and associated ground thermal stress in Adventdalen, Svalbard 

      Romeyn, Rowan Peter; Hanssen, Alfred; Köhler, Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-25)
      The small-aperture Spitsbergen seismic array (SPITS) has been in continuous operation at Janssonhaugen for decades. The high-Arctic location in the Svalbard archipelago makes SPITS an ideal laboratory for the study of cryoseisms, a nontectonic class of seismic events caused by freeze processes in ice, ice–soil, and ice–rock materials. We extracted a catalog of > 100 000 events from the nearly ...

    • Microphone recording of flexural waves for estimation of lake ice thickness 

      Romeyn, Rowan Peter; Hanssen, Alfred (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-20)
      In this study we took an intentionally low-tech approach, aiming to estimate key physical parameters of lake ice using a single, inexpensive microphone. We consider this approach highly relevant to the issue of transport safety and the relatively high number of accidents involving breakthrough failure of thin ice underlines the importance of this topic. We conducted a range of experiments on three ...
