(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Volatile emissions to the atmosphere associated with the Siberian Traps eruptions at the Permian-Triassic boundary were sourced from the outgassing of primary magmas and the sedimentary host rocks into which they were ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract There is a pressing need for transformative change, with a vision of long-term human well-being within planetary boundaries. The lack of progress—despite increasing awareness and action—illustrates how challenging ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Thawing of subsea permafrost can impact offshore infrastructure, affect coastal erosion, and release permafrost organic matter. Thawing is usually modeled as the result of heat transfer, although salt diffusion may play ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)CO2 release from thawing permafrost is both a consequence of, and a driver for, global warming, making accurate information on the Arctic carbon cycle essential for climate predictions. Eddy covariance data obtained from ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The presence of ground ice in Arctic soils exerts a major effect on permafrost hydrology and ecology, and factors prominently into geomorphic landform development. As most ground ice has accumulated in near-surface permafrost, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Studies of mineral equilibria in metamorphic rocks have given valuable insights into the tectonic processes operating at convergent plate margins during an orogeny. Geodynamic models simulating orogenesis and crustal ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Abstract The subsolidus phase diagram of silica in the 80–220 GPa pressure range was determined by density functional theory (DFT). The transition pressures calculated using the generalized gradient approximation ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)We present an experimental method to study time-dependent, CO2-induced, local topography changes in mm-sized composite samples, plus results showing heterogeneous swelling of coal and shale on the nano- to micrometer scale. ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)In contrast to coseismic pulverization of crystalline rocks, observations of coseismic pulverization in porous sedimentary rocks in fault damage zones are scarce. Also, juxtaposition of stiff crystalline rocks and compliant ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Earthquake rupture in strong, anhydrous lower continental crust requires high brittle failure stresses unless high pore fluid pressures are present. Several mechanisms proposed to generate high stresses at depth imply ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Seismic activity below the standard seismogenic zone is difficult to investigate because the geological records of such earthquakes, pseudotachylytes, are typically reacted and/or deformed. Here, we describe unusually ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Few localities are as important as the outcrops of the remnants of the Alpine Tethys margins exposed in European Alps in the development of new concepts on the temporospatial evolution of magma-poor rifted margins. The ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)Coeval pseudotachylytes (solidified melts produced during seismic slip) and mylonites are generally regarded as the geological record of transient seismic events during dominant ductile flow. Thermal runaway has been ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)SUMMARY We present a P-wave velocity model of the upper mantle, obtained from finite-frequency body-wave tomography, to analyse the relationship between deep and surface structures in Fennoscandia, one of the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Quantitative knowledge about which natural and anthropogenic factors influence the global spread of plague remains sparse. We estimated the worldwide spreading velocity of plague during the Third Pandemic, using more than ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Specimens resembling the benthic foraminifera Nonionella stella (Cushman and Moyer, 1930), a morphospecies originally described from the San Pedro Basin, California, USA, were observed for the first time in the Oslofjord ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Subarctic permafrost peatlands are important soil organic carbon pools, and improved knowledge about peat properties and peatland sensitivity to past climate change is essential when predicting future response to a warmer ...
-
(Master thesis / Masteroppgave, 2007)Diatom analyses were carried out on two sediment cores, one from the North Labrador Sea and one from Davis Strait, West Greenland, in order to investigate Holocene climatic variability in relation to ocean circulation. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)Abstract High‐Alpine regions are prone to a large variety of geohazards, among which earthquakes have the strongest impact on landscape and local population. Historic records indicate a moderate to high seismic activity ...
