Inception of the Northern European Ice Sheet due to contrasting ocean and insolation forcing
(Peer reviewed; Journal article, 2007-01)About 115,000 years ago the last interglacial reached its terminus and nucleation of new ice sheet growth was initiated. Evidence from the northernmost Nordic Seas indicate that the inception of the last glacial was related ... -
Increased ventilation of Antarctic deep water during the warm mid-Pliocene
(Peer reviewed; Journal article, 2013-02-19)The mid-Pliocene warm period is a recent warm geological period that shares similarities with predictions of future climate. It is generally held the mid-Pliocene Atlantic Meridional Overturning Circulation must have been ... -
Independent tephrochronological evidence for rapid and synchronous oceanic and atmospheric temperature rises over the Greenland stadial-interstadial transitions between ca. 32 and 40 ka b2k
(Journal article; Peer reviewed, 2020)Understanding the dynamics that drove past abrupt climate changes, such as the Dansgaard-Oeschger (DO) events, depends on combined proxy evidence from disparate archives. To identify leads, lags and synchronicity between ... -
Influence and reactivation of pre-existing rift faults during the development of an overlying fault network, northern Browse Basin, NW Australia
(Master thesis, 2017-10-13)Focusing on multiple events and interaction of different fault networks with the time being common in extensional settings such as passive margins and continental rifts. This study aims to better understand the interaction ... -
Influence of fault geometry on seismic registrations
(Master thesis, 2019-06-26)One of the main objectives of seismic interpretation is the identification and positioning of structural discontinuities, e.g. faults, fractures, pinch-outs and karsts. Seismic diffractions encode the seismic response from ... -
Influence of frozen ground on seismic data
(Master thesis, 2012-08-02)The interest for subsurface exploration in the arctic is increasing. Thus knowledge about the effects of glaciers and permafrost on seismic data is needed. This thesis focuses on five questions that are relevant in this ... -
The influence of magmatic intrusions on diagenetic processes and stress accumulation
(Peer reviewed; Journal article, 2019-11-13)Diagenetic changes in sedimentary basins may alter hydrocarbon reservoir quality with respect to porosity and permeability. Basins with magmatic intrusions have specific thermal histories that at time of emplacement and ... -
The influence of structural inheritance and multiphase extension on rift development, the northern North Sea
(Peer reviewed; Journal article, 2019-11-08)The northern North Sea rift evolved through multiple rift phases within a highly heterogeneous crystalline basement. The geometry and evolution of syn‐rift depocenters during this multiphase evolution and the mechanisms ... -
The influence of the pre-existing structuring on the evolution and geometry of extensional fault systems in the northern North Sea rift system
(Doctoral thesis, 2017-10-03)The structural style and fault evolution in rift basins affected by pre-existing structuring differ considerably from those developing above the homogeneous crust, because pre-existing structures are likely to reactivate ... -
Influence of Zones of Pre-Existing Crustal Weakness on Strain Localization and Partitioning During Rifting: Insights From Analog Modeling Using High-Resolution 3D Digital Image Correlation
(Journal article; Peer reviewed, 2021)Pre-existing crustal structures are known to influence rifting, but the factors controlling their influence remain poorly understood. We present results of digital image correlation that allows for the surface strain ... -
Innsjøsedimentasjon og klimautvikling i de polare Uralfjellene
(Master thesis, 2015-06-01)Denne oppgaven vil prøve å avdekke hvor lenge Bol. Schuchye (67°51'N, 66°22'Ø) i de polare Uralfjellene har vært isfri, og hvordan innsjøsedimentasjonen og klimautviklingen har vært i denne perioden. 102 sparker-profiler ... -
Insights into past tectonism from authigenic quartz
(Journal article; Peer reviewed, 2021)Authigenic quartz grains carry information that is diagnostic for the thermal history and thereby the burial depth and uplift of sediments. Recycled quartz grains with embayed or rounded authigenic remnants have been ... -
Insolation and Glacial Meltwater Influence on Sea‐Ice and Circulation Variability in the Northeastern Labrador Sea During the Last Glacial Period
(Journal article; Peer reviewed, 2019)The variable amounts of ice rafted debris (IRD) and foraminifers in North Atlantic sediments are related to the abrupt, millennial‐scale alteration from Greenland stadials to interstadials during the last glacial period ... -
Integrated 4D tectono-stratigraphic evolution of the northern Peloponnese margin and the Gulf of Corinth, Greece
(Master thesis, 2019-06-26) -
An integrated approach for seismic characterization of carbonates
(Doctoral thesis, 2010-11-09) -
An integrated deep learning and object-based image analysis approach for mapping debris- covered glaciers
(Journal article; Peer reviewed, 2023)Evaluating glacial change and the subsequent water stores in high mountains is becoming increasingly necessary, and in order to do this, models need reliable and consistent glacier data. These often come from global ... -
An integrated geological characterization of marine ground conditions in the North Sea
(Doctoral thesis, 2023-11-30)Geologiske karakterisering av marine grunnforhold for ankre og fundamenter for vindturbinder store vindkraftverk til havs er et relativt nytt felt. Som sådan er etableringen av beste praksis for integrering av geologiske, ... -
An integrated geological characterization of the Mid-Pleistocene to Holocene geology of the Sørlige Nordsjø II offshore wind site, southern North Sea
(Journal article; Peer reviewed, 2024)Subsurface deposits in recently glaciated marine areas are highly heterogeneous, representing a range of glacial and postglacial environments and processes including glacitectonism, overconsolidation, fluvial and lacustrine ... -
Integrating Multidisciplinary Observations in Vent Environments (IMOVE): Decadal Progress in Deep-Sea Observatories at Hydrothermal Vents
(Journal article; Peer reviewed, 2022-05-13)The unique ecosystems and biodiversity associated with mid-ocean ridge (MOR) hydrothermal vent systems contrast sharply with surrounding deep-sea habitats, however both may be increasingly threatened by anthropogenic ...
