Dansgaard-Oeschger cycles: Interactions between ocean and sea ice intrinsic to the Nordic seas
(Peer reviewed; Journal article, 2013-09)Dansgaard-Oeschger (D-O) cycles are the most dramatic, frequent, and wide-reaching abrupt climate changes in the geologic record. On Greenland, D-O cycles are characterized by an abrupt warming of 10 ± 5°C from a cold ... -
Deciphering the metamorphic framework of ophiolite alteration and devolatilization at Linnajarvi, N-Norway
(Master thesis, 2021-12-01)Kvitfjell ultramafic body is one of around 20 ultramafic bodies found in the Linnajavri area of Northern Norway. These ultramafic fragments are situated within the Köli Nappe of the Upper Allochthon in the Caledonian ... -
Deep Crustal Flow Within Postorogenic Metamorphic Core Complexes: Insights From the Southern Western Gneiss Region of Norway
(Peer reviewed; Journal article, 2019)Viscous crustal flow can exhume once deeply buried rocks in postorogenic metamorphic core complexes (MCCs). While migmatite domes record the flow dynamics of anatectic crust, the mechanics and kinematics of solid‐state ... -
Deep sea sedimentary analogs for the Vostok ice core
(Peer reviewed; Journal article, 2003-08-07)Many applications of the Vostok ice core depend critically on the ability to make stratigraphic ties to marine records in the adjacent Southern Ocean. Here we present oxygen isotopic records from high accumulation rate ... -
Deep-ocean circulation in the North Atlantic during the Plio-Pleistocene intensification of Northern Hemisphere Glaciation (~2.65–2.4 Ma)
(Journal article; Peer reviewed, 2021)Through transporting heat around the world and thereby regulating global climate, ocean circulation is an integral part of Earth's climate system that likely changed substantially on glacial-interglacial timescales in the ... -
Deep-water sediment transport patterns and basin floortopography in early rift basins: Plio-Pleistocene syn-rift of theCorinth Rift, Greece
(Peer reviewed; Journal article, 2019)Our current understanding on sedimentary deep‐water environments is mainly built of information obtained from tectonic settings such as passive margins and foreland basins. More observations from extensional settings are ... -
Deep-water sinuous channels: their development and architecture
(Doctoral thesis; Peer reviewed, 2011-12-02)The study combines an interpretation of 3D seismic and well-core dataset with laboratory experiments, process-based 3D numerical simulations and analysis of outcrop analogues to explore the varied architecture and formative ... -
Deep-water syn-rift stratigraphy as archives of Early-Mid Pleistocene palaeoenvironmental signals and controls on sediment delivery
(Journal article; Peer reviewed, 2021)The timing and character of coarse siliciclastic sediment delivered to deep-water environments in active rift basins is governed by the complicated interactions of tectonics, climate, eustasy, hinterland geology, and shelf ... -
The DeepMIP contribution to PMIP4: methodologies for selection, compilation and analysis of latest Paleocene and early Eocene climate proxy data, incorporating version 0.1 of the DeepMIP database
(Peer reviewed; Journal article, 2019-07-25)The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time that Earth's atmospheric CO2 concentrations exceeded 1000 ppm. Global mean temperatures were also substantially warmer than those ... -
Deformation bands in chalk - control on distribution and mechanism of formation
(Master thesis, 2016-06-01)Deformation bands are narrow tabular zones that accommodates strain through the reorganization of grains by shearing and/or volumetric deformation in porous and granular rocks. Deformation bands in porous sandstones are ... -
Deformation bands in porous sandstones, their microstructure and petrophysical properties
(Doctoral thesis, 2008-02-27)Deformation bands are commonly thin tabular zones of crushed or reorganized grains that form in highly porous rocks and sediments. Unlike a fault, typically the slip is negligible in deformation bands. In this dissertation ... -

Deglaciation of Fennoscandia
(Peer reviewed; Journal article, 2015-10-21)To provide a new reconstruction of the deglaciation of the Fennoscandian Ice Sheet, in the form of calendar-year time-slices, which are particularly useful for ice sheet modelling, we have compiled and synthesized published ... -
The deglaciation of Kongsfjorden, Svalbard —based on surface exposure dating of glacial erratics and Quaternary geological mapping of Blomstrandhalvøya
(Master thesis, 2016-05-27)Surface exposure dating via 10Be cosmogenic nuclide dating is used, alongside Quaternary geological mapping of landforms and sediments, to reconstruct the course of deglaciation following the Late Weichselian Glacial Maximum ... -
Deglaciation of the Norwegian fjords
(Doctoral thesis, 2018-01-09)Melting glaciers and ice sheets are perhaps the most visible signs of a warming cli- mate. Glaciers are retreating on every continent, ice sheets are shedding icebergs into a warming ocean at an accelerating rate, and the ... -
Deglaciation of the Scandinavian Ice Sheet and a Younger Dryas ice cap in the outer Hardangerfjorden area, southwestern Norway
(Journal article; Peer reviewed, 2021)Understanding past responses of ice sheets to climate change provides an important long-term context for observations of present day, and projected future, ice-sheet change. In this work, we reconstruct the deglaciation ... -
Deglasiasjon og holocene havnivåendringer i Lofthus, Ullensvang kommune, basert på kvartærgeologisk kartlegging og eksponeringsdatering
(Master thesis, 2018-10-24)Observations from Quaternary geological mapping, LIDAR-data, aerial photo analysis and results from surface exposure dating via in situ ^10Be are used to reconstruct Holocene sea-level changes and the course of deglaciation ... -
Deglasiasjon og strandforskyvning på Bokn, Sørvest-Norge.
(Master thesis, 2017-06-29)In this master thesis the late glacial shoreline displacement on Bokn is presented. The data is based on identification of the isolation and ingression contacts in sediment cores from the two isolation basins Gunnarstavatnet ... -
