Seasonal zooplankton dynamics in Svalbard coastal waters: The shifting dominance of mero- and holoplankton and timing of reproduction in three species of Copepoda
(Master thesis, 2019-06-15)Monthly sampling was conducted in the ice-free Adventfjorden in West Spitsbergen, Svalbard, from March to November 2018 to assess the seasonal development in the Arctic zooplankton community and to investigate the seasonally ... -
Skillful prediction of Barents Sea ice cover
(Peer reviewed; Journal article, 2015-07-08)A main concern of present climate change is the Arctic sea ice cover. In wintertime, its observed variability is largely carried by the Barents Sea. Here we propose and evaluate a simple quantitative and prognostic framework ... -
Spatial Patterns, Mechanisms, and Predictability of Barents Sea Ice Change
(Journal article; Peer reviewed, 2022)Recent Arctic winter sea ice loss has been most pronounced in the Barents Sea. Here we explore the spatial structure of Barents Sea ice change as observed over the last 40 years. The dominant mode of winter sea ice ... -
Spawning during an oil spill: how exposure to the water-accommodated fraction of crude oil may disrupt polar cod (Boreogadus saida) reproduction
(Master thesis, 2020-07-01)Declining ice cover in the Arctic has made it possible to extract oil reserves in areas that were once unreachable. However, all oil exploration comes with an inherent risk of spills. Conditions in the Arctic may increase ... -
Species composition, distribution and ecology of the demersal fish community along the Norwegian coast north of Stad under varying environmental conditions
(Master thesis, 2019-06-14)In the last decades, temperatures of the Atlantic current that enters the Norwegian Coastal Current (NCC) has been above the yearly average, with 2007 as the warmest registration on record (Skagseth 2012). The climatic ... -
Strong microsite control of seedling recruitment in tundra
(Peer reviewed; Journal article, 2010-12-19)The inclusion of environmental variation in studies of recruitment is a prerequisite for realistic predictions of the responses of vegetation to a changing environment. We investigated how seedling recruitment is affected ... -
A study on the Atmospheric Boundary Layer in the High Arctic during winter
(Master thesis, 2016-08-26)We investigated the stable boundary layer in Adventdalen by measuring meteorological parameters with Sonic anemometers at two heights, as well as slow response measurements, during a 7 week measurement campaign from February ... -
Turbulent heat and momentum fluxes in the upper ocean under Arctic sea ice
(Peer reviewed; Journal article, 2017-02)We report observations of heat and momentum fluxes measured in the ice-ocean boundary layer from four drift stations between January and June 2015, covering from the typical Arctic basin conditions in the Nansen Basin to ... -
Water mass transformation in the Greenland Sea during the period 1986-2016
(Peer reviewed; Journal article, 2019-01)Hydrographic measurements from ships, autonomous profiling floats, and instrumented seals over the period 1986–2016 are used to examine the temporal variability in open-ocean convection in the Greenland Sea during winter. ...
