Disko Bay sea-ice variability: Oceanic and Atmospheric drivers
(Master thesis, 2023-11-20)Climate change impacts the Arctic sea-ice cover and thickness with a related Arctic Amplification and an increased ocean heat transport towards the Arctic. There has been a profound decline of Arctic winter sea-ice extent, ... -
Dispersal limitations matter for microbial morphospecies
(Peer reviewed; Journal article, 2006)In contrast with macroorganisms, whose geographical ranges are typically restricted, many microbial species appear to have cosmopolitan distributions. This observation has been explained as a consequence of ubiquitous ... -
Dispersal syndromes are poorly associated with climatic niche differences in the Azorean seed plants
(Journal article; Peer reviewed, 2021)Aim Environmental niche tracking is linked to the species ability to disperse. While well investigated on large spatial scales, dispersal constraints also influence small-scale processes and may explain the difference ... -
Dispersion and abundance of salmon lice (Lepeophtheirus salmonis) in a Norwegian fjord system
(Master thesis, 2011-11-20)Based on numerical results of currents from a high resolution fjord model, dispersion of salmon lice (Lepeophtheirus salmonis) in the Hardangerfjord has been modelled. The results show that salmon lice abundance in the ... -
Dispersion and two-phase flow in material from different carbonate pore classes
(Master thesis, 2008-06-02)Carbonate reservoirs are currently estimated to contain more than 50 % of the world's oil reserves. The economical value of improving knowledge on fluid flow in these reservoirs is therefore vast. Carbonate reservoirs are ... -
Dispersion of Mine Particles in Førdefjorden
(Master thesis, 2023-10-10)Førdefjorden is the site of a newly permitted submarine tailing disposal (STD) in Norway, and it is nationally debated. Major implications of an STD can be toxic compounds of the tailing, severe impacts on the benthic ... -
Dispersive Estimates for Full Dispersion KP Equations
(Journal article; Peer reviewed, 2021)We prove several dispersive estimates for the linear part of the Full Dispersion Kadomtsev–Petviashvili introduced by David Lannes to overcome some shortcomings of the classical Kadomtsev–Petviashvili equations. The proof ... -
Displacement/Length Scaling Relationships for Normal Faults; a Review, Critique, and Revised Compilation
(Journal article; Peer reviewed, 2022)The relationship between normal fault displacement (D) and length (L) varies due to numerous factors, including fault size, maturity, basin tectonic history, and host rock lithology. Understanding how fault D and L relate ... -
Dissecting peripheral protein-membrane interfaces
(Journal article; Peer reviewed, 2022-12-14)Peripheral membrane proteins (PMPs) include a wide variety of proteins that have in common to bind transiently to the chemically complex interfacial region of membranes through their interfacial binding site (IBS). In ... -
Dissecting the Transcriptional Regulatory Properties of Human Chromosome 16 Highly Conserved Non-Coding Regions
(Peer reviewed; Journal article, 2011-09-13)Non-coding DNA conservation across species has been often used as a predictor for transcriptional enhancer activity. However, only a few systematic analyses of the function of these highly conserved non-coding regions ... -
Dissipation measurements using temperature microstructure from an underwater glider
(Peer reviewed; Journal article, 2014-09)Microstructure measurements of temperature and current shear are made using an autonomous underwater glider. The glider is equipped with fast-response thermistors and airfoil shear probes, providing measurements of dissipation ... -
The dissipation of kinetic energy in the Lofoten Basin Eddy
(Peer reviewed; Journal article, 2018-06)Ocean microstructure, current, and hydrography observations from June 2016 are used to characterize the turbulence structure of the Lofoten Basin eddy (LBE), a long-lived anticyclone in the Norwegian Sea. The LBE had an ... -
Dissipation of turbulent kinetic energy inferred from Seagliders: an application to the eastern Nordic Seas overflows
(Peer reviewed; Journal article, 2012-12)Turbulent mixing is an important process controlling the descent rate, water mass modification, and volume transport augmentation due to entrainment in the dense overflows across the Greenland–Scotland Ridge. These overflows, ... -
Dissolution from a liquid CO2 lake disposed in the deep ocean
(Peer reviewed; Journal article, 2003)The dissolution from a liquid CO2 lake source located at a flat ocean bottom at 3,000 m depth is investigated. Using the unsteady, two-dimensional advection–diffusion equation, temporal and spatial distribution of CO2 ... -
The dissolution of a miscible drop rising or falling in another liquid at low Reynolds number
(Journal article; Peer reviewed, 2023)“A basic and basically unsolved problem in fluid dynamics is to determine the evolution of rising bubbles and falling drops of one miscible liquid in another” [D. D. Joseph and Y. Y. Renardy, Fundamentals of Two-Fluid ... -
Dissolved gases in hydrothermal plumes from Artic vent fields
(Master thesis, 2013-10-30)Recent discoveries of active vent fields on slow and ultraslow spreading ridges have revealed that hydrothermal activity is more common than previously assumed. In the Norwegian-Greenland Sea, two such vent fields are ... -
Dissolved Oxygen and Biochemical Oxygen Demand in the waters close to the Quelimane sewage discharge
(Master thesis, 2010-06-01)The River dos Bons Sinais Estuary is one of the most important estuaries in the central region of the Mozambican coast. It is situated between the confluence of Cuácua and Licuári rivers and the Mozambican Channel in the ... -
distantia: an open-source toolset to quantify dissimilarity between multivariate ecological time-series
(Peer reviewed; Journal article, 2020)There is a large array of methods to extract knowledge and perform ecological forecasting from ecological time‐series. However, in spite of its importance for data‐mining, pattern‐matching and ecological synthesis, methods ... -
Distinct genetic clustering in the weakly diferentiated polar cod, Boreogadus saida Lepechin, 1774 from East Siberian Sea to Svalbard
(Journal article; Peer reviewed, 2021)The cold-adapted polar cod Boreogadus saida, a key species in Arctic ecosystems, is vulnerable to global warming and ice retreat. In this study, 1257 individuals sampled in 17 locations within the latitudinal range of ... -
Distinguishing the roles of dispersal in diversity maintenance and in diversity limitation
(Peer reviewed; Journal article, 2005-07)In recent years, a considerable research effort has gone into studying how dispersal might affect the diversity of local communities. While this general topic has received attention from theoretical and empirical ecologists ...
