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 ... -
Distribution and autecology of chrysophyte cysts from high Arctic Svalbard lakes: preliminary evidence of recent environmental change
(Peer reviewed; Journal article, 2004)Chrysophycean stomatocyst assemblages were analysed from the sediments of 17 lakes and ponds from Svalbard as one component of a multi-proxy investigation of recent environmental change in the high Arctic. Sediment cores ... -
Distribution and feeding ecology of fin (Balaenoptera physalus) and humpback whales (Megaptera novaeangliae) in the Norwegian Sea during the summers of 2013 to 2018
(Master thesis, 2019-06-14)This study aims at describing the current (2013 to 2018) summer distribution and feeding ecology of fin whales (Balaenoptera physalus) and humpback whales (Megaptera novaeangliae) in the Norwegian Sea. These waters function ... -
Distribution and Occurrence Frequency of dB/dt Spikes During Magnetic Storms 1980–2020
(Journal article; Peer reviewed, 2022)The physical magnetospheric cause for geomagnetically induced currents (GICs) are rapid time-varying magnetic fields (dB/dt), which occur mainly during magnetic substorms and storms. When, where and why exactly such rapid ... -
Distribution and spread of the invasive slug Arion vulgaris Moquin - Tandon in Norway
(Peer reviewed; Journal article, 2013)The present distribution of the invasive slug Arion vulgaris Moquin-Tandon was studied in Norway. This important pest species has spread to many parts of Europe during the last decades, inflicting damage to agriculture and ... -
Distribution and suitable habitat of the cold-water corals Lophelia pertusa, Paragorgia arborea, and Primnoa resedaeformis on the Norwegian continental shelf
(Journal article; Peer reviewed, 2020)Cold-water corals are habitat-forming species that are also classified as indicators of vulnerable marine ecosystems (VMEs) due to the threat of various anthropogenic impacts, e.g., fisheries and oil/mineral exploration. ... -
Distribution of deformation associated with relay and tip damage zones of normal faults - a case study from Kilve, UK
(Master thesis, 2017-06-13)The aim of this study is to investigate and characterize distribution of deformation and damage associated with relays and tips of normal faults at a range of scales. This is done through field based studies and digital ... -
Distribution of discontinuous Mudstone beds within wavedominated shallow-marine deposits: Star point sandstone and blackhawk formation, Eastern Utah
(Journal article; Peer reviewed, 2014)Deposits of wave-dominated shorelines are typically considered to act as relatively simple hydrocarbon reservoirs and are commonly modeled as “tanks of sand.” However, important heterogeneities that can act as barriers to ... -
Distribution of energetic oxygen and hydrogen in the near-Earth plasma sheet
