Ground penetrating radar for archaeology in Western Norway: Examples from Lyse Abbey and Fana burial mound
(Master thesis, 2021-06-01)In recent years, ground penetrating radar (GPR) has been an important geophysical tool in archaeological prospecting in Norway with discoveries of high interest such as viking ships and iron age settlements. Western Norway ... -
Ground-based and Satellite Remote Sensing of Atmospheric Aerosols and Ultraviolet Solar Radiation
(Doctoral thesis, 2016-04-08)Satellite remote sensed data have been used to determine the aerosol climatology and to investigate the influence of the aerosol index (AI) on the ultraviolet (UV) index in coastal land areas in Serrekunda (13.28◦ N, 16.34◦ ... -
Ground-based measurements of total ozone column amount with a multichannel moderate-bandwidth filter instrument at the Troll research station, Antarctica
(Journal article; Peer reviewed, 2020)Combining information from several channels of the Norwegian Institute for Air Research (NILU-UV) irradiance meter, one may determine the total ozone column (TOC) amount. A NILU-UV instrument has been deployed and operated ... -
Grounding Performance under Lightning Surges in High Voltage Substations
(Master thesis, 2018-06-16)To achieve electromagnetic compatibility (EMC) and sufficient protection against lighting transients in the power transmission system, understanding of the grounding system transient behavior becomes crucial when deviating ... -
Groundwater fluctuations during a debris flow event in western Norway - Triggered by rain and snowmelt
(Journal article; Peer reviewed, 2021)Pore pressure is crucial in triggering debris slides and flows. Here we present measurements of groundwater pore pressure and temperature recorded by a piezometer 1.6 m below the surface on a slope susceptible to debris ... -
Growing Ice in a Tank: Young Sea Ice Evolution and Turbulence in the Under Ice Boundary Layer
(Master thesis, 2011-11-14)Thin sea ice and its modifications of the oceanic boundary layer are important in the context of the recent retreat of the Arctic sea ice cover. To study turbulence in the under ice boundary layer during thin sea ice growth, ... -
Growth and competition in a warmer ocean: a field experiment with a non-native and two native habitat-building seaweeds
(Peer reviewed; Journal article, 2017-06-21)Kelps and fucoids are important members of temperate seaweed communities, but may be negatively impacted by climate change and non-native species. We used a field experiment to investigate the effect of higher temperatures ... -
Growth and diel vertical migration patterns of the toxic dinoflagellate Protoceratium reticulatum in a water column with salinity stratification: the role of bioconvection and light
(Peer reviewed; Journal article, 2015-11-12)Novel data on growth and migratory behaviour of a southern Norwegian strain of Protoceratium reticulatum (Dinophyceae) were obtained from long-lasting (14-22 d) experiments in a water column with salinity gradient (ΔS = 4 ... -
Growth and energy metabolism in Atlantic salmon (Salmo salar), with possible positive effects of starvation at elevated temperature
(Master thesis, 2014-02-25)Due to global warming, the sea water temperature will probably increase, which may affect cold- water species like Atlantic salmon. It is therefore of great importance to see how elevated temperature will affect the growth ... -
Growth and retreat of the last British–Irish Ice Sheet, 31 000 to 15 000 years ago: the BRITICE-CHRONO reconstruction
(Journal article; Peer reviewed, 2022)The BRITICE-CHRONO consortium of researchers undertook a dating programme to constrain the timing of advance, maximum extent and retreat of the British–Irish Ice Sheet between 31 000 and 15 000 years before present. The ... -
Growth characteristics and morphology of Paramoeba perurans from Atlantic salmon Salmo salar L. and ballan wrasse Labrus bergylta in Norway
(Journal article; Peer reviewed, 2023)Background Paramoeba perurans is the causative agent of amoebic gill disease (AGD) in Atlantic salmon Salmo salar L. and many other farmed marine fish species worldwide. The first cases of AGD in Norway were reported in ... -
Growth of Atlantic salmon (Salmo salar) under different regimes of continuous aerobic exercise
(Master thesis, 2023-06-02)To ensure the Atlantic salmon aquaculture industry's sustainable growth, the development and implementation of new production strategies is needed. A strategy that has been adopted by the industry to intensify the salmon’s ... -
Growth of collisional orogens from small and cold to large and hot ‐ inferences from geodynamic models
(Journal article; Peer reviewed, 2021)It is well documented that the interplay between crustal thickening and surface processes determines growth of continent-continent collision orogens from small and cold to large and hot. Additionally, studies have demonstrated ... -
Growth performance and welfare of post-smolt (Salmo salar L.) reared in semi closed containment systems (S-CCS) – a comparative study
(Master thesis, 2020-06-23)The salmon industry faces challenges related to sea lice infestations, escapees, diseases and environmental impact. Semi closed containment systems (S-CCS) have been proposed to abate these challenges. In the S-CCS, cultured ... -
Growth Performance, Nutrient Digestibility, and Retention in Atlantic Salmon, Salmo salar L., Fed Diets with Fermented Sugar Kelp, Saccharina latissima
(Journal article; Peer reviewed, 2023)Using low trophic marine resources such as sugar kelp (Saccharina latissimi) is of great interest to increase the circular food production in the ocean. Sugar kelp does, however, contain high levels of carbohydrates and ... -
Growth portfolios buffer climate-linked environmental change in marine systems
(Journal article; Peer reviewed, 2022)Large-scale, climate-induced synchrony in the productivity of fish populations is becoming more pronounced in the world's oceans. As synchrony increases, a population's “portfolio” of responses can be diminished, in turn ... -
Growth reaction norms of domesticated, wild and hybrid Atlantic salmon families in response to differing social and physical environments
(Peer reviewed; Journal article, 2013-10-28)Background: Directional selection for growth has resulted in the 9-10th generation of domesticated Atlantic salmon Salmo salar L. outgrowing wild salmon by a ratio of approximately 3:1 when reared under standard hatchery ... -
