Passive seismic recording of cryoseisms in Adventdalen, Svalbard
Romeyn, Rowan; Hanssen, Alfred; Ruud, Bent Ole; Stemland, Helene Meling; Johansen, Tor Arne (Journal article; Peer reviewed, 2021)A series of transient seismic events were discovered in passive seismic recordings from 2-D geophone arrays deployed at a frost polygon site in Adventdalen, Svalbard. These events contain a high proportion of surface wave ... -
Potential Use of Time-Lapse Surface Seismics for Monitoring Thawing of the Terrestrial Arctic
Stemland, Helene Meling; Johansen, Tor Arne; Ruud, Bent Ole (Journal article; Peer reviewed, 2020)The terrestrial Arctic is warming rapidly, causing changes in the degree of freezing of the upper sediments, which the mechanical properties of unconsolidated sediments strongly depend upon. This study investigates the ... -
Seismic acquisition and analysis in a changing Arctic
Stemland, Helene Meling (Doctoral thesis, 2020-12-03)In the Arctic, temperatures are regularly low enough that water exists in its frozen state, either in the form of ice, snow, or frozen ground. The effective elastic properties of a material depend on the elastic properties ... -
Seismic Acquisition in a Shallow Marine Sea Ice Covered Environment: The Significance of Survey Geometry and Possible Impacts on Pinnipeds
Stemland, Helene Meling (Master thesis, 2017-06-27)Seismic surveying of Arctic environments is important for both economic and environmental reasons. The world energy demand is increasing, and new areas need to be explored to cover the demand. One of the new areas where ...
