Ambient noise levels and detection threshold in Norway
(Peer reviewed; Journal article, 2016-07)Ambient seismic noise is caused by a number of sources in specific frequency bands. The quantification of ambient noise makes it possible to evaluate station and network performance. We evaluate noise levels in Norway from ... -
Atmosphere-driven ice sheet mass loss paced by topography: Insights from modelling the south-western Scandinavian Ice Sheet
(Peer reviewed; Journal article, 2018-09)Marine-terminating glaciers and ice streams are important controls of ice sheet mass balance. However, understanding of their long-term response to external forcing is limited by relatively short observational records of ... -
Chemical characterization of 21 species of marine macroalgae common in Norwegian waters: benefits of and limitations to their potential use in food and feed
(Peer reviewed; Journal article, 2018-01-18)BACKGROUND: In the past few years, much effort has been invested into developing a new blue economy based on harvesting, cultivating and processing marine macroalgae in Norway. Macroalgae have high potential for a wide ... -
Distribution of marine, benthic, shell bearing gastropods along the Norwegian coast
(Peer reviewed; Journal article, 2009)Based on literature data and my extensive material from along the coast, the distribution of shell bearing marine, benthic gastropods known from Norwegian waters, is outlined. The geographic area covered goes down to c. ... -
Effects of geography and species variation on selenium and mercury molar ratios in Northeast Atlantic marine fish communities
(Peer reviewed; Journal article, 2019-11-01)Methylmercury (MeHg) is a potent neurotoxin that bioaccumulates in seafood. Co-occurrence of selenium (Se) may affect the bioavailability and toxicity of MeHg in organisms. Here we report the concentrations of total mercury ... -
Feeding response to fish feed diets in Ciona intestinalis; implications for IMTA
(Master thesis, 2016-05-20)Norway is the largest salmon producer in the world. The associated discharge with continued growth from salmon production has vitalised interest in developing integrated multi trophic aquaculture (IMTA) in order to mitigate ... -
Impacts on carbon budgets of increased use og Norwegian forest resources for energy
(Master thesis, 2019-06-19)When forests are logged for heat and electricity production, emissions from burning of the biomass are not accounted for in national greenhouse gas reporting to the climate convention. This would have been correct if a ... -
Infection dynamics and tissue tropism of Parvicapsula pseudobranchicola (Myxozoa: Myxosporea) in farmed Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2018-01-06)Background The myxosporean parasite Parvicapsula pseudobranchicola commonly infects farmed Atlantic salmon in northern Norway. Heavy infections are associated with pseudobranch lesions, runting and mortality in the salmon ... -
Life after fire: the impact of fire on species composition and diversity in coastal heathlands
(Doctoral thesis, 2015-09-11)Fire prone coastal heathlands are widespread, and range from naturally fire prone Mediterranean-type heathlands, to the anthropogenic heathlands of north-west Europe. Regardless of its source, fire is an important disturbance ... -
Natural and cultural heritage in mountain landscapes: towards an integrated valuation
(Peer reviewed; Journal article, 2012)Mountain areas of Europe have been managed by humans for a long time, leading to a prevalence of semi-natural habitats in mountain landscapes today. These landscapes contain both natural and cultural heritage; however, ... -
Nodavirus in farmed Atlantic cod Gadus morhua in Norway
(Peer reviewed; Journal article, 2007-09-14)Viral encephalopathy and retinopathy (VER) was diagnosed in 5 to 24 g sized farmed Atlantic cod Gadus morhua kept in sea cages at Parisvatn, Hordaland county, on the west coast of Norway. Moderate mortality (10 to 15%) was ... -
Norwegian Biology, Medicine and Psychology Undergraduate Students´ Acceptance of Modern Evolutionary Theory Using the I-SEA Survey Instrument
(Master thesis, 2017-11-02)584 undergraduate students from three disciplines and four public universities in Norway were sampled during the spring of 2014 for acceptance of modern evolutionary theory using the I-SEA survey instrument developed by ... -
Recent increases in species richness and shifts in altitudinal distributions of Norwegian mountain plants
(Peer reviewed; Journal article, 2003)Opportunities for observing long-term changes in natural biota are rare. Observations on the distribution and frequency of vascular plants were performed on 23 mountains situated along a west–east gradient in Jotunhei men, ... -
Recreational fishing for Atlantic bluefin tuna in Norwegian waters : A detailed look at the fishing effort and economic value of this new fishery.
(Master thesis, 2021-09-24)Recreational fishing is a popular hobby and ecosystem service around the world, yet the impact of recreational fishing on both fish populations and local economies is often overlooked. This thesis will look at the fishing ... -
Seismic hazard in Norway due to large earthquakes
(Master thesis, 2015-06-01)There are many faults located in Norway, posing as potential earthquake sources. Even though the seismicity is characterized as low to moderate, earthquakes of magnitude 3.5 or lower occur regularly. The seismic hazard ... -
Simulating the climatic response of Hardangerjøkulen in southern Norway since the Little Ice Age
(Master thesis, 2014-05-24)Glacier and ice cap volume changes currently amount to half of the total contribution from the cryosphere to sea-level rise. Ice caps and their outlet glaciers are dynamically different from the Greenland and Antarctic ice ... -
Spatial distribution of mercury in seawater, sediment, and seafood from the Hardangerfjord ecosystem, Norway
(Peer reviewed; Journal article, 2019-06-01)Hardangerfjord is one of the longest fjords in the world and has historical mercury (Hg) contamination from a zinc plant in its inner sector. In order to investigate the extent of Hg transferred to abiotic and biotic ... -
