Lineamenter Brudd og seismisitet i relasjon til grunnvann på Bømlo, Vestlandet
(Master thesis, 2003)Dette arbeidet er et resultat av feltarbeid på øygruppen Bømlo i Sunnhordland, Vestlandet, samt fjernanalyse av topo- og fotolineamenter, numeriske og analytiske modeller. En analyse av 389 topolineamenter viser en ... -
Linking an Early Triassic delta to antecedent topography: Source-to-sink study of the southwestern Barents Sea margin
(Peer reviewed; Journal article, 2018-01)Present-day catchments adjacent to sedimentary basins may preserve geomorphic elements that have been active through long intervals of time. Relicts of ancient catchments in present-day landscapes may be investigated using ... -
Linking regional unconformities in the Barents Sea to compression-induced forebulge uplift at the Triassic-Jurassic transition
(Peer reviewed; Journal article, 2019)The Triassic-Jurassic transition marks an important change in the basin configuration of the Greater Barents Sea. A contiguous basin with km-thick sedimentary successions changed into a partitioned basin with uplift in the ... -
Linking sediment supply variations and tectonic evolution in deep time, source-to-sink systems—The Triassic Greater Barents Sea Basin
(Journal article; Peer reviewed, 2021)Triassic strata in the Greater Barents Sea Basin are important records of geodynamic activity in the surrounding catchments and sediment transport in the Arctic basins. This study is the first attempt to investigate the ... -
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 ... -
Lithofacies, petrography, and geochemistry of the Lamphun oceanic plate stratigraphy: As a record of the subduction history of Paleo-Tethys in Chiang Mai-Chiang Rai Suture Zone of Thailand
(Journal article; Peer reviewed, 2024)The Mélange in Lamphun Province, situated in the southern region of the Chiang Mai-Chiang Rai Suture Zone (CMCRSZ), remains inadequately explored. This study employs field investigations and petrographic analysis to delineate ... -
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 ...
