Etablering av holocen askestratigrafi i innsjøarkiver for Vest-Norge
(Master thesis, 2020-07-04)Askestratigrafi er et mye brukt verktøy til kronostratigrafisk korrelering og datering. For vest-norske innsjøer er det tefrakronologiske rammeverket svært begrenset, og en etablering av en askestratigrafi derfra kan gi ... -
Eurasian Ice Sheet collapse was a major source of Meltwater Pulse 1A 14,600 years ago
(Journal article; Peer reviewed, 2020)Rapid sea-level rise caused by the collapse of large ice sheets is a threat to human societies. In the last deglacial period, the rate of global sea-level rise peaked at more than 4 cm yr−1 during Meltwater Pulse 1A, which ... -
European summer temperatures since Roman times
(Journal article; Peer reviewed, 2016)The spatial context is critical when assessing present-day climate anomalies, attributing them to potential forcings and making statements regarding their frequency and severity in a long-term perspective. Recent international ... -
Evaluating balanced section restoration with thermochronology data: A case study from the Central Pyrenees
(Peer reviewed; Journal article, 2014-05-06)We present a new method that can be used to quantitatively evaluate the consistency between balanced section restorations and thermochronological data sets from orogenic belts. We have applied our method to a crustal-scale ... -
Evaluating the large-scale hydrological cycle response within the Pliocene Model Intercomparison Project Phase 2 (PlioMIP2) ensemble
(Journal article; Peer reviewed, 2021)The mid-Pliocene (∼3 Ma) is one of the most recent warm periods with high CO2 concentrations in the atmosphere and resulting high temperatures, and it is often cited as an analog for near-term future climate change. Here, ... -
Evidence for rapid paraglacial formation of rock glaciers in southern Norway from 10Be surface-exposure dating
(Journal article; Peer reviewed, 2020-04-16)We evaluate the timing and environmental controls on past rock-glacier activity at Øyberget, upper Ottadalen, southern Norway, using in situ 10Be surface-exposure dating on (1) boulders belonging to relict rock-glacier ... -
Evidence for regional cooling, frontal advances, and East Greenland Ice Sheet changes during the demise of the last interglacial
(Peer reviewed; Journal article, 2016)High-resolution lithic and sea surface climate records are used to portray the progression of North Atlantic climate, hydrography, and Greenland Ice Sheet (GIS) activity through the peak of Marine Isotope Stage (MIS) 5e ... -
Evidence for the asynchronous retreat of large outlet glaciers in southeast Greenland at the end of the last glaciation
(Journal article, 2014-09-01)Recent rapid changes in the marine-terminating sectors of the Greenland Ice Sheet (GrIS) have prompted concerns about the future stability of the ice sheet. Long-term records of ice sheet behaviour provide valuable context ... -
Evidence for three North Sea tsunamis at the Shetland Islands between 8000 and 1500 years ago
(Journal article, 2005-08)Coastal fen- and lake deposits enclose sand layers that record at least three Holocene tsunamis at the Shetland Islands. The oldest is the well-known Storegga tsunami (ca 8100 cal yr BP), which at the Shetlands invaded ... -
Evidence of a South Asian Proto-Monsoon During the Oligocene-Miocene Transition
(Journal article; Peer reviewed, 2021)The geological history of the South Asian monsoon (SAM) before the Pleistocene is not well-constrained, primarily due to a lack of available continuous sediment archives. Previous studies have noted an intensification of ... -
Evolution of a major segmented normal fault during multiphase rifting: The origin of plan-view zigzag geometry
(Peer reviewed; Journal article, 2015-05)This case study addresses fault reactivation and linkage between distinct extensional episodes with variable stretching direction. Using 2-D and 3-D seismic reflection data we demonstrate how the Vesterdjupet Fault Zone, ... -
The evolution of catchment-depositional system relationships on the dip slopes of intra-rift basement highs: an example from the Frøya High, Mid-Norwegian Rifted Margin
(Journal article; Peer reviewed, 2023)Basement highs form one of many potential sediment source areas during the evolution of continental rifts and rifted margins and add to the topographic complexity typical of active rifts. Footwall basement highs acting as ... -
Evolution of normal fault systems in physical analogue experiments

Evolution of normal faults and fault-related damage: insights from physical experiments
(Master thesis, 2016-06-01)Our understanding of the growth of natural extensional faults is limited to the study of a random snapshot in time, namely that of present day, aided by various techniques to reconstruct fault growth history. Furthermore, ... -
Evolution of ore-forming fluids in a post-collisional porphyry Cu-Au system: A case study from the Bučim deposit, Republic of North Macedonia
(Journal article; Peer reviewed, 2022)The Bučim porphyry Cu-Au deposit is situated in the westernmost part of the Serbo-Macedonian Massif, Republic of North Macedonia. The deposit is hosted by Precambrian gneisses with tectonically imbedded rare lenses of ... -
Evolution of Rift Architecture and Fault Linkage During Continental Rifting: Investigating the Effects of Tectonics and Surface Processes Using Lithosphere-Scale 3D Coupled Numerical Models
(Journal article; Peer reviewed, 2022)Continental rifts grow by propagation, overlap and linkage of individual fault segments. These processes are influenced by erosion and sedimentation and generate complex three-dimensional fault-interaction patterns. We use ... -
Evolution of talc- and carbonate-bearing alterations in ultramafic rocks on Leka (central Norway)
(Master thesis, 2014-02-05)The thesis focuses on several low-angle fracture zones within the ultramafic section of the Leka Ophiolite Complex, central Norway, along which the original lithology has been completely serpentinized and carbonated. The ... -
Evolution of tropical land temperature across the last glacial termination
(Journal article; Peer reviewed, 2022)The tropical West Pacific hosts the warmest part of the surface ocean and has a considerable impact on the global climate system. Reconstructions of past temperature in this region can elucidate climate connections between ... -
Exceptionally high heat flux needed to sustain the Northeast Greenland Ice Stream
(Journal article; Peer reviewed, 2020)The Northeast Greenland Ice Stream (NEGIS) currently drains more than 10 % of the Greenland Ice Sheet area and has recently undergone significant dynamic changes. It is therefore critical to accurately represent this feature ...
