Down-dip correlation and modelling of shallow-marine and estuarine deposits in the Sunnyside Member, Book Cliffs, Eastern Utah: implications for the formation of non-depositional discontinuity surfaces
(Master thesis, 2005-11)The Sunnyside Member is part of the Blackhawk Formation and consists of shallow-marine and estuarine deposits reflecting high-frequency changes in sea level. Detailed mapping of the unit reveals an intra parasequence ... -
Drainage integration and sediment dispersal in active continental rifts: A numerical modelling study of the central Italian Apennines
(Journal article; Peer reviewed, 2018)Progressive integration of drainage networks during active crustal extension is observed in continental areas around the globe. This phenomenon is often explained in terms of headward erosion, controlled by the distance ... -
Drilling for the Archean Roots of Life and Tectonic Earth in the Barberton Mountains
(Peer reviewed; Journal article, 2009) -
Driving Mechanisms of an Extreme Winter Sea Ice Breakup Event in the Beaufort Sea
(Journal article; Peer reviewed, 2022)The thick multiyear sea ice that once covered large parts of the Arctic is increasingly being replaced by thinner and weaker first-year ice, making it more vulnerable to breakup by winds. We use the neXtSIM sea ice model ... -
Drumlin relief
(Peer reviewed; Journal article, 2012)Drumlin relief is a key parameter for testing predictions of models of drumlin formation. Although this metric is commonly described in textbooks as being of the order of a fewtens ofmetres, our critical review of the ... -
Dynamic Topography Development North of Iceland from Subaerial Exposure of the Igneous Logi Ridge, NE Atlantic
(Peer reviewed; Journal article, 2019)The Logi Ridge, located north of the West Jan Mayen Fracture Zone, is E-W oriented and 140-150 km long. The seafloor surrounding the Logi Ridge is ~0.65 km shallower than the conjugate seafloor east of the Mohn’s Ridge, ... -
Dynamics of Spontaneous (Multi) Centennial‐Scale Variations of the Atlantic Meridional Overturning Circulation Strength During the Last Interglacial
(Journal article; Peer reviewed, 2020)Recent reconstructions of bottom water δ13C during the last interglacial (LIG) suggest short-lived variability in the Atlantic meridional overturning circulation (AMOC). Spontaneous (multi) centennial-scale variability of ... -
Dynamics of the Northeast Greenland Ice Stream: the role of geothermal heat and subglacial hydrology
(Doctoral thesis, 2019-11-15)Ice streams are rivers of fast flowing ice, crucial for the mass balance of ice sheets. The Greenland Ice Sheet shows a complex flow pattern, where a few major ice streams drain most of the ice sheet, contributing to sea ... -
Early Holocene Temperature Oscillations Exceed Amplitude of Observed and Projected Warming in Svalbard Lakes
(Journal article; Peer reviewed, 2019)Arctic climate is uniquely sensitive to ongoing warming. The feedbacks that drive this amplified response remain insufficiently quantified and misrepresented in model scenarios of future warming. Comparison with paleotemperature ... -
Early Pliocene onset of modern Nordic Seas circulation related to ocean gateway changes
(Peer reviewed; Journal article, 2015-10-28)The globally warm climate of the early Pliocene gradually cooled from 4 million years ago, synchronous with decreasing atmospheric CO2 concentrations. In contrast, palaeoceanographic records indicate that the Nordic Seas ... -
Early post-deglaciation shorelines and sea-level changes along Hardangerfjorden and adjacent fjord areas, W. Norway
(Doctoral thesis, 2008-09-05) -
Earthquake Damage and Loss Assessment – Predicting the Unpredictable
(Doctoral thesis, 2013-05-10) -
Earthquake statistics changed by typhoon-driven erosion
(Journal article; Peer reviewed, 2020)Tectonics and climate-driven surface processes govern the evolution of Earth’s surface topography. Topographic change in turn influences lithospheric deformation, but the elementary scale at which this feedback can be ... -
Earthquake triggered submarine slides in Norway
(Master thesis, 2017-12-16)Towards the end of the last glacial period, several episodes of submarine mass failures has taken place both in Norwegian fjords and on the continental shelf. Submarine mass failures have the potential of generating tsunamis ... -
Earthquake-induced landslides in Norway
(Journal article; Peer reviewed, 2023)Norway is located in an intraplate setting with low-to-moderate seismicity. The mountainous landscape leads to a high level of landside activity throughout the country. Earthquake-induced landslides (EQILs) are common in ... -
Earthquakes track subduction fluids from slab source to mantle wedge sink
(Peer reviewed; Journal article, 2019)Subducting plates release fluids as they plunge into Earth’s mantle and occasionally rupture to produce intraslab earthquakes. It is debated whether fluids and earthquakes are directly related. By combining seismic ... -
Ecology and genomic diversity of iron-oxidizing bacteria at Arctic deep-sea hydrothermal vents: Lessons from genome-resolved metagenomics and microscopy
(Doctoral thesis, 2024-05-08)Jernoksiderende bakterier er globalt utbredt og har betydelig innvirkning på syklusen av jern i miljøet. Imidlertid har få slike bakterier blitt dyrket i laboratoriet og det finnes lite kunnskap om hvordan ulike miljøforhold ... -

Eemian Greenland ice sheet simulated with a higher-order model shows strong sensitivity to surface mass balance forcing
(Peer reviewed; Journal article, 2019-08-15)The Greenland ice sheet contributes increasingly to global sea level rise. Its history during past warm intervals is a valuable reference for future sea level projections. We present ice sheet simulations for the Eemian ...
