A flexural isostasy model for the Pleistocene evolution of the Barents Sea bathymetry
(Journal article; Peer reviewed, 2017)The topographic relief of the Barents Sea was subjected to major changes during the past 1.5 million years mostly due to sediment redistribution driven by glacial activity. This paper addresses the problem of Pleistocene ... -
Detecting multiscale karst features including hidden caves using microgravimetry in a Caledonian nappe setting: Mefjell massif, Norway.
(Journal article; Peer reviewed, 2018)Cave passages and karst features form negative density contrasts expressed in gravity field anomalies. We present an interpretation approach for microgravimetry, applicable for challenging geological settings with heterogeneous ... -
Fluid flow properties of the Wilhelmøya Subgroup, a potential unconventional CO2 storage unit in central Spitsbergen
(Journal article; Peer reviewed, 2018)The Upper Triassic to Middle Jurassic Wilhelmøya Subgroup forms one of the more suitable reservoir units on the Norwegian Arctic archipelago of Svalbard. The target siliciclastic storage unit, which is encountered at approx. ... -
Geophysical expression of the Leka Ophiolite, Norway modeled from integrated gravity, magnetic and petrophysical data
(Journal article; Peer reviewed, 2018)The ca. 497 Ma Leka Ophiolite Complex (LOC) comprises oceanic lithosphere that formed near the margin of Laurentia in a suprasubductionzone setting. The LOC was obducted onto Laurentia in the Early Ordovician and later ... -
Gravitational reactivation of a pre-existing post-Caledonian fault system: the deep-seated gravitational slope deformation at Middagstinden, western Norway
(Journal article; Peer reviewed, 2016)The origin of linear features in mountain terrain that form distinct vertical steps is generally not obvious and has been discussed to be related to either tectonic faulting or gravitational slope deformation. A strong ... -
Magnetic anomalies of the mafic/ultramafic seiland igneous province
(Journal article; Peer reviewed, 2018)The Ediacaran Seiland Igneous Province (SIP) is the largest complex of mafic-ultramafic intrusions in northern Fennoscandia and one of the few examples of a well preserved deep-seated magmatic plumbing system. The major ...
