Deep-sequencing of the bacterial microbiota in commercial-scale recirculating and semi-closed aquaculture systems for Atlantic salmon post-smolt production
(Peer reviewed; Journal article, 2016-10-20)New aquaculture production systems are evolving for prolong production of Atlantic salmon smolts or post-smolts before stocking in traditional net pens, such as semi-closed containment systems (S-CCS) in sea (Fig. 1) and ... -
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 deepening of the Atlantic water in the Lofoten Basin of the Norwegian Sea, demonstrated by using an active reduced gravity model
(Peer reviewed; Journal article, 2004-06-29)The Norwegian Atlantic Current (NwAC) as a poleward eastern boundary current is to be considered as the northern limb of the Meridional Overturning Circulation in the North Atlantic (MOC). It transports warm and saline ... -
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 ... -
DeepOtolith v1.0: An Open-Source AI Platform for Automating Fish Age Reading from Otolith or Scale Images
(Journal article; Peer reviewed, 2022-05-29)Every year, marine scientists around the world read thousands of otolith or scale images to determine the age structure of commercial fish stocks. This knowledge is important for fisheries and conservation management. ... -
Defect detection and acoustic penetration of grout in offshore structures

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

Deformations of rational surface singularities and reflexive modules with an application to flops
(Peer reviewed; Journal article, 2018)Blowing up a rational surface singularity in a reflexive module gives a (any) partial resolution dominated by the minimal resolution. The main theorem shows how deformations of the pair (singularity, module) relates to ... -

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 ...
