Drilling for the Archean Roots of Life and Tectonic Earth in the Barberton Mountains
(Peer reviewed; Journal article, 2009) -
Drivers of Megabenthic Community Structure in One of the World’s Deepest Silled-Fjords, Sognefjord (Western Norway)
(Journal article; Peer reviewed, 2020-06-09)The Sognefjord is the longest (205 km) and deepest (1308 m) fjord in Norway, and the second-longest in the world. Coast-fjord exchange in Sognefjord is limited by a seaward sill at 170 m water depth, which causes a clear ... -
Drivers of spatial variability in spring bloom onset and magnitude along a latitudinal gradient in the Nordic Seas
(Master thesis, 2018-06-21)Spring phytoplankton blooms in the Nordic Seas contribute a large proportion of global primary production, and their timing and magnitude heavily impacts higher trophic levels. Two key drivers of bloom development, ... -
Drivers of the marine CO2 system in the High Arctic - from the deep basins to the shallow fjords
(Doctoral thesis, 2019-02-20)The High Arctic is largely undersampled in terms of marine CO2 system data due to the cold dark season and often an extensive sea ice cover. The current understanding of the Arctic carbon cycle is thus vulnerable to both ... -
Drivers of the summer-distribution of Northeast Atlantic mackerel (Scomber scombrus) in the Nordic Seas from 2011 to 2017; a Bayesian hierarchical modelling approach
(Peer reviewed; Journal article, 2019-03)Identifying factors that are statistically correlated with the geographical distribution dynamics of a species can facilitate our understanding of causal physiological and ecological relationships. Northeast Atlantic (NEA) ... -
Drivers of variation in the predator-prey interaction between cod and capelin in the Barents Sea
(Doctoral thesis, 2019-05-27)Cod (Gadus morhua) and capelin (Mallotus villosus) are commercially important species with key roles in the Barents Sea ecosystem. Cod is a major predator on capelin, and fluctuations in the capelin stock has influenced ... -
Driving Factors for Levelized Cost of Energy in Floating Wind Farms
(Master thesis, 2022-06-01)This thesis presents a method for calculating LCOE for offshore floating wind farms. A method has been created that aims to do a life cycle cost analysis, with emphasis on the cost of installation and transportation, and ... -
Driving forces in the distributions of the three most common deep-water coral species in Norway: Lophelia pertusa, Paragorgia arborea, and Primnoa resedaeformis
(Master thesis, 2017-12-20)This thesis explores a set of environmental variables may be used to predict the spatial distribution of the three most common cold-water coral (CWC) species in Norway: Lophelia pertusa, Paragorgia arborea, and Primnoa ... -
Driving Mechanisms of an Extreme Winter Sea Ice Breakup Event in the Beaufort Sea
(Journal article; Peer reviewed, 2022)The thick multiyear sea ice that once covered large parts of the Arctic is increasingly being replaced by thinner and weaker first-year ice, making it more vulnerable to breakup by winds. We use the neXtSIM sea ice model ... -
DRLMA: An Intelligent Move Acceptance for Combinatorial Optimization Problems based on Deep Reinforcement Learning
(Master thesis, 2023-07-01)Numerous heuristic solution methods have been developed to tackle combinatorial opti- mization problems, often customized for specific problem domains and use-cases where they exhibit remarkable performance. However, their ... -
Drum Analysis
(Master thesis, 2002)This thesis studies drumloops, and the possibility to separate the different drumsounds from each other. Drum onsets and the detection of these are thoroughly discussed. Different approaches for detection and separation ... -
Drumlin relief
(Peer reviewed; Journal article, 2012)Drumlin relief is a key parameter for testing predictions of models of drumlin formation. Although this metric is commonly described in textbooks as being of the order of a fewtens ofmetres, our critical review of the ... -
Dual lidar wind measurements along an upstream horizontal line perpendicular to a suspension bridge
(Journal article; Peer reviewed, 2021)Remote wind sensing can complement traditional anemometry at a bridge site and contribute to an improved wind-resistant design of long-span bridges. This study examines wind lidar measurement data recorded along a ... -
Dual staining with CFDA-AM and SYTOX Blue in flow cytometry analysis of UV-irradiated Tetraselmis suecica to evaluate vitality
(Peer reviewed; Journal article, 2016)After disinfection of ballast water, it is crucial to detect organisms and determine their vitality to assess the performance of the chosen treatment technique. Ultraviolet (UV) irradiation is a treatment technology commonly ... -
Dual virtual element methods for discrete fracture matrix models
(Peer reviewed; Journal article, 2019)The accurate description of fluid flow and transport in fractured porous media is of paramount importance to capture the macroscopic behavior of an oil reservoir, a geothermal system, or a CO2 sequestration site, to name ... -
Dual-Lobe Reconnection and Horse-Collar Auroras
(Journal article; Peer reviewed, 2020)We propose a mechanism for the formation of the horse-collar auroral configuration during periods of strongly northward interplanetary magnetic field (IMF), invoking the action of dual-lobe reconnection (DLR). Auroral ... -

Duration of the parasitic phase determines subsequent performance in juvenile freshwater pearl mussels (Margaritifera margaritifera)
(Peer reviewed; Journal article, 2017-03)Host–parasite systems have been useful in understanding coevolutionary patterns in sympatric species. Based on the exceptional interaction of the long‐lived and highly host‐specific freshwater pearl mussel (FPM; Margaritifera ... -
Dying for change: A roadmap to refine the fish acute toxicity test after 40 years of applying a lethal endpoint
(Journal article; Peer reviewed, 2021)The fish acute toxicity test (TG203; OECD, 2019) is frequently used and highly embedded in hazard and risk assessment globally. The test estimates the concentration of a chemical that kills 50% of the fish (LC50) over a ... -
Dying from the lesser of three evils: facilitation and non-consumptive effects emerge in a model with multiple predators
(Peer reviewed; Journal article, 2019)Prey modify their behaviour to avoid predation, but dilemmas arise when predators vary in hunting style. Behaviours that successfully evade one predator sometimes facilitate exposure to another predator, forcing the prey ...
