Deep submarine infiltration of altered geothermal groundwater on the south Chilean Margin
(Journal article; Peer reviewed, 2022)Submarine groundwater discharge is increasingly recognized as an important component of the oceanic geochemical budget, but knowledge of the distribution of this phenomenon is limited. To date, reports of meteoric inputs ... -
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 sand transfer by hyperpycnal flows, the Eocene of Spitsbergen, Arctic Norway
(Journal article; Peer reviewed, 2023)Flood-generated hyperpycnal flows are dense, sediment-laden, turbulent flows that can form long-lived, bottom-hugging turbidity currents, which undoubtedly transport large volumes of fine-grained sediments into the ocean. ... -
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, 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 ... -
Deformation of sandstone reservoirs. Insight from experiments and field studies
(Doctoral thesis, 2014-09-18) -
Deghosting dual-component streamer data using demigration-based supervised learning
(Journal article; Peer reviewed, 2024)Ghost reflections from the free surface distort the source signature and generate notches in the seismic amplitude spectrum. For this reason, removing ghost reflections is essential to improve the bandwidth and signal-to-noise ... -
Deglacial changes in western Atlantic sea surface temperatures and ice sheet variability
(Master thesis, 2023-04-11) -
Deglaciation history of Frøyabanken and Halsafjorden, Norway
(Master thesis, 2023-02-06)This thesis aims to reconstruct post-glacial ice sheet dynamics on the Norwegian coast and adjacent continental shelf area, a region for which there is significant uncertainty regarding ice sheet movement due to a lack of ... -
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 highest mountains in Scandinavia at the Younger Dryas–Holocene transition: evidence from surface exposure-age dating of ice-marginal moraines
(Journal article; Peer reviewed, 2023)Surface exposure–age dating was applied to rock surfaces associated with ice-marginal moraines at elevations of ~1520–1780 m a.s.l. on the slopes of Galdhøpiggen and Glittertinden, the two highest mountains in Scandinavia ... -
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 ... -
Deglasial isdynamikk på Vesterålenmarginen
(Master thesis, 2019-06-13)Hvordan marinbaserte isdekker og isstrømmer responderer på endringer i miljø og klima er et stort usikkerhetsmoment i klimaforskning. Derfor er det viktig å studere hvordan tidligere isdekker og isstrømmer responderte på ...
