Distribution of thermochemical output and associated ecosystems at the Loki’s Castle hydrothermal field
(Master thesis, 2020-12-04)Loki’s Castle is a hydrothermal vent field situated on the ultra-slow Arctic mid-Ocean ridges, at the boundary of the Mohns- and Knipovich segments (73◦30’N, 08◦E), and consists of two sulfide mounds and associated black ... -
Do deformation bands matter forflow? Insights from permeability measurements and flow simulations in porous carbonate rocks
(Peer reviewed; Journal article, 2017-02)We investigate the permeability and flow effects of deformation bands in porous granular carbonate rocks in Malta and use results from flow simulations to discuss the practical implications of deformation bands in carbonate ... -
Double-Difference Relocation and Empirical Green’s Function Analysis of Storfjorden Earthquakes
(Master thesis, 2017-06-08)On 21 February 2008, an earthquake of magnitude Mw 6.1 occurred in Storfjorden on Svalbard. Since then, more than 2000 earthquakes have been recorded in this region. More recently, on 29 March 2016, an earthquake of magnitude ... -
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 ... -

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

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 ... -
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 ... -
