A Comparative Study of the Spawning Phenology of Cod (Gadus morhua), Saithe (Pollachius virens), and Haddock (Melanogrammus aeglefinus): a Geographical Perspective along the Norwegian Coast
(Master thesis, 2023-06-02)Reproductive traits are a fundamental aspect of an organism's life history and play a critical role in shaping population dynamics, as these traits can significantly influence offspring survival rates and, thereby, ... -
Centennial changes in water clarity of the Baltic Sea and the North Sea
(Peer reviewed; Journal article, 2013-10-10)Secchi depth is a valuable proxy for detecting long term changes in the water clarity of oceanic and coastal ecosystems. We analyse approximately 40 000 observations, which are available from ICES, from the Baltic Sea and ... -
A Diagnostic Diagram to Understand Atmosphere-ocean Dynamics in the Southern North Sea at High Wind Spe
(Peer reviewed; Journal article, 2014)Long time series of offshore meteorological measurements in the lower marine atmospheric boundary layer show dynamical regimes and variability that are forced partly by interaction with the underlying sea surface and partly ... -
Directional wave measurements using an autonomous vessel
(Peer reviewed; Journal article, 2016-08-01)An autonomous vessel, the Offshore Sensing Sailbuoy, was used for wave measurements near the Ekofisk oil platform complex in the North Sea (56.5º N, 3.2º E, operated by ConocoPhillips) from 6 to 20 November 2015. Being 100 ... -
Spatiotemporal dynamics in the acoustic backscatter of plankton and lesser sandeel (Ammodytes marinus) in the North Sea measured using a Saildrone
(Master thesis, 2021-06-01)With accelerating global warming and human activities, the North Sea is one of the marine ecosystems undergoing rapid change. The need for spatially-temporally extendable survey platforms for assisting well-established ... -
A taxonomic review of the Norwegian species of Raphitoma (Gastropoda: Conoidea: Raphitomidae)
(Peer reviewed; Journal article, 2016)The problematic conoidean genus Raphitoma s.l. in inshore Norwegian waters is revised based on fresh material from all along the coast of Norway. This largely shallow water group is represented by at least six species in ... -
Technetium-99 (99Tc) in the North and Nordic Seas – the present status (2010) and a compilation of the Institute of Marine Research’s monitoring data (2003-2009)
(Master thesis, 2011-04-26)Technetium-99 (99Tc) is an anthropogenic, pure β-emitting (Emax = 292 keV) radionuclide with a half-life of 2.13 · 10^5 years. It is present in the marine environment primarily due to discharges from nuclear fuel reprocessing ... -
Variability in transport of fish eggs and larvae. IV. Interannual variability in larval stage duration of immigrating plaice in the Dutch Wadden Sea
(Peer reviewed; Journal article, 2009-09-18)Larval immigration of plaice Pleuronectes platessa L. into the western Wadden Sea in spring was followed biweekly from 1993 to 2002. For each year (1993 excluded), 150 settling individuals were selected and used for ...
