Linking the basement geology along the Africa-South America coasts in the South Atlantic
(Peer reviewed; Journal article, 2016-07)The match of geological units of the dissected Kaoko-Dom Feliciano-Gariep orogenic system exposed along the coasts of the South Atlantic is poorly understood. Two suites of intrusive rocks crop out in the Angra Fria Bay ... -
Linking the high-resolution architecture of modern and ancient wave-dominated deltas: Processes, products, and forcing factors
(Peer reviewed; Journal article, 2019)Wave-dominated deltas are often fed by single trunk distributary channels which can remain the primary source of sediment supply to the delta for periods of thousands of years. Consequently, the sedimentary architecture ... -
Links Between Faulting, Topography, and Sediment Production During Continental Rifting: Insights From Coupled Surface Process, Thermomechanical Modeling
(Journal article; Peer reviewed, 2022)Continental rifts form by extension, and their subsequent evolution depends on the tectonic and climatic boundary conditions. We investigate how faulting, topography, and the evolution of the sediment flux during rifting ... -
Listvenite formation at Gråberget, east-central Norway. A natural analogue for geological CO2 sequestration involving sulphide mineralization
(Master thesis, 2023-08-04)The migration of hydrothermal CO2-bearing fluids from sedimentary crustal units into tectonically emplaced ultramafic mantle rocks has for a long time been an important topic in geology, due to its association with the ... -
Lithological controls on architecture and development of igneous intrusions in sedimentary basins.
(Doctoral thesis, 2023-11-24)Magmatransport i jordskorpen forekommer igjennom magmatiske intrusjoner (siller og diker), som ofte omtales som et magmatisk rørsystem. Disse nettverkene av magma finnes i de fleste sedimentære bassenger over hele verden, ... -
The 'Little Ice Age' – only temperature?
(Peer reviewed; Journal article, 2003)Understanding the climate of the last few centuries, including the 'Little Ice Age', may help us better understand modern-day natural climate variability and make climate predictions. The conventional view of the climate ... -
The ‘Little Ice Age’ advance of Nigardsbreen, Norway: A cross-disciplinary revision of the chronological framework
(Journal article; Peer reviewed, 2023)This study presents a cross-disciplinary revision of the Little Ice Age (LIA) advance of Nigardsbreen glacier, an outlet from Jostedalsbreen ice cap in western Norway. The associated glacier foreland is characterised by a ... -
Liverpool Land Basement High, Greenland: Visualising inputs for fractured crystalline basement reservoir models
(Peer reviewed; Journal article, 2019-07-22)Basement highs are large structural features, commonly buried in sedimentary basins (Busby & Azor 2012). They are of interest for natural resources exploration and research because of their ability to influence migration ... -
Localized crustal deformation along the central North Anatolian Fault Zone revealed by joint inversion of P-receiver functions and P-wave polarizations
(Peer reviewed; Journal article, 2019)The North Anatolian Fault Zone (NAFZ) is a major plate boundary that separates the Eurasian Plate to the north from the Anatolian Plate to the south and is associated with powerful damaging earthquakes. Despite numerous ... -
Long-term sustainability of a distributed RI: the EPOS case
(Journal article; Peer reviewed, 2022)The European Plate Observing System (EPOS) is a distributed research infrastructure (RI) with the mission to establish and maintain sustainable and long-term access to solid Earth science data and services by integrating ... -
The Longyearbyen CO2 Lab: Fluid communication in reservoir and caprock
(Peer reviewed; Journal article, 2017-08)The Longyearbyen CO2 Lab of Svalbard, Norway was established to estimate the potential for geological carbon sequestration at Spitsbergen. Several monitoring wells were drilled in and around the planned CO2 injection site. ... -
Long‐Term Coupling and Feedback Between Tectonics and Surface Processes During Non‐Volcanic Rifted Margin Formation
(Journal article; Peer reviewed, 2019)Here we present high‐resolution 2‐D coupled tectonic‐surface processes modeling of extensional basin formation. We focus on understanding feedbacks between erosion and deposition and tectonics during rift and passive margin ... -
Long‑term demise of sub‑Antarctic glaciers modulated by the Southern Hemisphere Westerlies
(Journal article; Peer reviewed, 2021)The accelerated melting of ice on the Antarctic Peninsula and islands in the sub-Antarctic suggests that the cryosphere is edging towards an irreversible tipping point. How unusual is this trend of ice loss within the frame ... -
A low climate threshold for south Greenland Ice Sheet demise during the Late Pleistocene
(Peer reviewed; Journal article, 2020-01-07)The Greenland Ice Sheet (GIS) has been losing mass at an accelerating rate over the recent decades. Models suggest a possible temperature threshold between 0.8 and 3.2 °C, beyond which GIS decline becomes irreversible. The ... -
Low-temperature thermochronological and structural study of the inner Hardangerfjord area, southern Norway
(Master thesis, 2012-10-29)The origin of the mountainous topography in southern Norway is at present unresolved. Post-Devonian sediments are absent onshore, making quantification of crustal uplift and fault displacements difficult. Low-temperature ... -
The Lærdal-Gjende Fault: A detailed structural and thermochronological study
(Master thesis, 2015-06-01)The development of the Caledonian orogen to a passive margin leaded to the present-day Norwegian landscape. The most recent denudation history in Mesozoic and Cenozoic times holds the key to the morphotectonic development ... -
Machine learning and artificial neural networks for seismic processing
(Doctoral thesis, 2023-05-05)Nylig har tilgjengeligheten av kraftige GPUer og "open source"-programvare gjort det mulig for kunstige nevrale nettverk å løse flere praktiske og industrielle problemer. Vi kan bruke nevrale nettverk til viktige seismiske ... -
Magmatism at Passive Margins: Effects of Depth-Dependent Wide Rifting and Lithospheric Counterflow
(Journal article; Peer reviewed, 2022)Rifted passive margins exhibit a large variety in the timing, distribution, and amount of magmatism. The factors controlling magmatism during rifted margin formation, remain, however, incompletely understood, partly owing ... -
The Making of the NEAM Tsunami Hazard Model 2018 (NEAMTHM18)
(Journal article; Peer reviewed, 2021)The NEAM Tsunami Hazard Model 2018 (NEAMTHM18) is a probabilistic hazard model for tsunamis generated by earthquakes. It covers the coastlines of the North-eastern Atlantic, the Mediterranean, and connected seas (NEAM). ... -
