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, ... -
A deeper look; Does Heincke´s law apply to Atlantic cod (Gadus morhua) in the Barents Sea and what is the effect of eye size on prey encounter rate?
(Master thesis, 2019-05-28)The Atlantic cod (Gadus morhua) is arguably one of the most valuable fish we have, and the Barents Sea stock, Northeast Arctic cod (NEAC), is the largest stock in the world. Despite the long history of fishing and the ... -
Barents Sea ice cover reflects Atlantic inflow
(Journal article, 2011)The recent Arctic winter sea-ice retreat is most pronounced in the Barents Sea. Using available observations of the Atlantic inflow to the Barents Sea and results from a regional ice-ocean model we assess the role of ... -
Climatic mean and interannual variation of northern Barents Sea water mass distribution and circulation. A combined study of ROMS, current and hydrography observations
(Master thesis, 2008-06-02)Evaluating current measurements, hydrography observations and model (ROMS) results of the northern Barents Sea, water mass distribution and circulation is investigated. Water mass exchange with the Arctic Ocean is linked ... -
Crustal transect from the Knipovich Ridge to Bear Island across the western Barents Sea margin
(Master thesis, 2010-06-08)A crustal model of a 322 km long transect from the Knipovich Ridge to Bear Island (Bjørnøya) has been obtained by use of reflection seismic data and wide angle Ocean Bottom Seismometer (OBS) data. Further constraints of ... -
Dense water formation and circulation in the Barents Sea
(Peer reviewed; Journal article, 2011)Dense water masses from Arctic shelf seas are an important part of the Arctic thermohaline system. We present previously unpublished observations from shallow banks in the Barents Sea, which reveal large interannual ... -
Diet variation in Barents Sea haddock (Melanogrammus aeglefinus)
(Master thesis, 2023-06-02)Diet composition and feeding are crucial for assessing fish species ecological role, population dynamics, and overall ecosystem health. It provides insights into fish’s functional role within the food web, and it contributes ... -
Element composition of particulate matter in the North-West Barents Sea
(Master thesis, 2022-08-10)At the dawn of the 21st century, the Arctic Ocean ecosystem is at great risk due to rapid climatic change. The ice edge retreat observed in the Barents Sea and other sub-Arctic areas is so substantial that has led researchers ... -
An evaluation of 0-group abundance indices of Barents Sea fish stocks
(Peer reviewed; Journal article, 2009-01-23)The International 0-group fish survey in the Barents Sea (1965-2002) aimed to give initial indication of the recruiting year class strengths. Since 2003 the 0-group survey has been a part of a Joint Norwegian-Russian ... -
Factors leading to variation of spawning time in the Barents Sea capelin (Mallotus villosus)
(Master thesis, 2015-11-20)Barents Sea capelin (Mallotus villosus) is a semalparous fish species, and the timing of spawning both in terms of age and season is variable. The present thesis explores potential factors leading to variation in timing ... -
From winter to late summer in the northwestern Barents Sea shelf: Impacts of seasonal progression of sea ice and upper ocean on nutrient and phytoplankton dynamics
(Journal article; Peer reviewed, 2024)Strong seasonality is a key feature of high-latitude systems like the Barents Sea. While the interannual variability and long-term changes of the Barents Sea are well-documented, the seasonal progression of the physical ... -
Late Triassic (Carnian) Palynology of the Northern Barents Sea (Sentralbanken High)
(Master thesis, 2014-06-23)This study is part of a broader palynological investigation of late Middle to Late Triassic, where the main aim is to improve the biostratigraphic resolution by applying palynology. The low abundance of macrofossils (e.g. ... -
Late Triassic (early Carnian) palynology of the shallow stratigraphic core 7830/3-U-1, offshore Kong Karls Land, Northern Barents Sea
(Master thesis, 2016-05-31)This study presents palynostratigraphic and palynofacies analyses from the shallow stratigraphic core 7830/3-U-1, drilled through the Snadd Formation (equivalent to De Geerdalen Formation) offshore Kong Karls Land in the ... -
Middle to Late Triassic (Ladinian to Carnian) palynology of shallow stratigraphic cores 7831/2-U-2 and 7831/2-U-1, offshore Kong Karls Land, Norwegian Arctic
(Master thesis, 2015-11-20)During the Triassic, the Barents Shelf was situated on the northwestern corner of the Pangaea supercontinent as a large epicontinental seaway. Into early Late Triassic (Carnian), a major delta, prograding from the southeast ... -
Seasonality and drivers of water column optical properties on the northwestern Barents Sea shelf
(Journal article; Peer reviewed, 2023)Hydrographic and bio-optical measurements were conducted along a south–north transect on the northwestern Barents Sea shelf from early spring to late summer in 2021. Strong climate change manifestations observed in this ... -
Seasonality of the Physical and Biogeochemical Hydrography in the Inflow to the Arctic Ocean Through Fram Strait
(Peer reviewed; Journal article, 2018-06-29)Eastern Fram Strait and the shelf slope region north of Svalbard is dominated by the advection of warm, salty and nutrient-rich Atlantic Water (AW). This oceanic heat contributes to keeping the area relatively free of ice. ... -
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 ... -
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 ...
