Imaging Discontinuities in the Lithospheric Mantle Using a New, Automated Ps and Sp Receiver Function Workflow
(Master thesis, 2020-12-10)Over the last decades, the receiver function technique has been widely established as a standard tool for surveying sharp changes in elastic properties of the Earth’s crust and upper mantle. To date, very few studies have ... -
Imaging of small-scale faults in seismic reflection data: Insights from seismic modelling of faults in outcrop
(Journal article; Peer reviewed, 2023)Faults with throws that fall below vertical seismic resolution are challenging to identify in reflection seismic datasets. Nevertheless, such small-scale faults may still affect the seismic images, and in this study, we ... -
Imaging Subduction Beneath Mount St. Helens: Implications for Slab Dehydration and Magma Transport
(Peer reviewed; Journal article, 2019)Mount St. Helens (MSH) is anomalously 35–50 km trenchward of the main Cascade arc. To elucidate the source of this anomalous forearc volcanism, the teleseismic‐scattered wavefield is used to image beneath MSH with a dense ... -
Imidazole Backbone Functionalization with Olefin Cross-Metathesis
(Journal article; Peer reviewed, 2022)A selective and high-rate Ru-catalyzed cross-metathesis reaction of alkenes with vinylimidazole is disclosed. Cross-metathesis is known to operate less efficiently on N-heterocycles, but through optimization by means of ... -
Immiscible Viscous Fingering: Modelling Unstable Water–Oil Displacement Experiments in Porous Media
(Journal article; Peer reviewed, 2022)Viscous fingering in porous media occurs when the (miscible or immiscible) displacing fluid has a lower viscosity than the displaced fluid. For example, immiscible fingering is observed in experiments where water displaces ... -
Immunoglobulin Isotypes in Atlantic Salmon, Salmo Salar
(Peer reviewed; Journal article, 2015-02)There are three major immunoglobulin (Ig) isotypes in salmonid fish: IgM, IgD and IgT, defined by the heavy chains , and , respectively. As a result of whole genome duplication in the ancestor of the salmonid fish family, ... -
Immunologiske responsar i huda hos sjøaure (Salmo trutta) ved infeksjon av lakselus (Lepeophtheirus salmonis) i preadulte stadiet
(Master thesis, 2022-06-01)Sjøaure er den anadrome delen av bestanden til brunaure (Salmo trutta). Arten gyter i elvar og bekkar før den smoltifiserer og vandrar ut i kystvatn for å finne større tilgang til føde og dermed vokse seg større. I kystvatn ... -
Immunrespons hos atlantisk laks (Salmo salar) ved infestasjon av lakselus (Lepeophtheirus salmonis): Endringer i genuttrykk og histologiske forandringer i hud
(Master thesis, 2021-06-01)Sammendrag Lakselus blir ansett som den største utfordringen knyttet til oppdrett i dag. Disse utfordningene kommer i form av redusert fiskehelse, økte produksjonskostnader samt tiltak og lovverk som begrenser vekst for ... -
Immunrespons mot Pasteurella spp. hjå rognkjeks (Cyclopterus lumpus L.) og Atlantisk laks (Salmo salar L.)
(Master thesis, 2021-06-01)Dei siste åra har ein sett ei dramatisk auke i tilfelle pasteurellose i norsk oppdrett av rognkjeks (Cyclopterus lumpus L.) og Atlantisk laks (Salmo salar L.). Sjukdommen førar til redusert fiskevelferd og kan innebere høg ... -
Impact and detectability of hypothetical CCS offshore seep scenarios as an aid to storage assurance and risk assessment
(Journal article; Peer reviewed, 2020)Carbon Capture and Storage has the potential to make a significant contribution to the mitigation of climate change, however there is a regulatory and societal obligation to demonstrate storage robustness and minimal local ... -
Impact assessment culture in the European Union. Time for something new?
(Journal article; Peer reviewed, 2023)Current approaches and cultures for the economic evaluations of environmental and health policies may suffer from excessive reliance on a standard neoclassic economic toolbox that neglects alternative perspectives. This ... -
The Impact of a Reduced High-Wind Charnock Parameter on Wave Growth With Application to the North Sea, the Norwegian Sea, and the Arctic Ocean
(Journal article; Peer reviewed, 2022)As atmospheric models move to higher resolution and resolve smaller scales, the maximum modeled wind speed also tends to increase. Wave models tuned to coarser wind fields tend to overestimate the wave growth under strong ... -
The impact of anti-sea lice pesticides, azamethiphos and deltamethrin, on European lobster (Homarus gammarus) larvae in the Norwegian marine environment
(Journal article; Peer reviewed, 2020)Anti-sea lice pesticides, used in the salmonid aquaculture industry, are a growing environmental concern due to their potential to adversely affect non-target crustaceans. Azamethiphos and deltamethrin are two bath treatment ... -
Impact of Antioxidant Feed and Growth Manipulation on the Redox Regulation of Atlantic Salmon Smolts
(Journal article; Peer reviewed, 2022-08-30)Accumulating evidence indicates a close relationship between oxidative stress and growth rate in fish. However, the underlying mechanisms of this relationship remain unclear. This study evaluated the combined effect of ... -
Impact of Arctic sea ice variations on winter temperature anomalies in northern hemispheric land areas
(Peer reviewed; Journal article, 2018-07-30)Coordinated numerical ensemble experiments with six different state-of-the-art atmosphere models have been used in order to evaluate the respective impact of the observed Arctic sea ice and sea surface temperature (SST) ... -
The impact of assimilating data from a remotely piloted aircraft on simulations of weak-wind orographic flow
(Journal article; Peer reviewed, 2014)Orographic winds near a 914 m high mountain in Southwest-Iceland are explored using unique observations made aloft with a small remotely piloted aircraft, as well as with traditional observations and high-resolution ... -
Impact of Assimilation of Radiosonde and UAV Observations from the Southern Ocean in the Polar WRF Model
(Journal article; Peer reviewed, 2020)Weather forecasting in the Southern Ocean and Antarctica is a challenge above all due to the rarity of observations to be assimilated in numerical weather prediction (NWP) models. As observations are expensive and logistically ... -
The Impact of Cold-Air Outbreaks and Oceanic Lateral Fluxes on Dense-Water Formation in the Greenland Sea from a 10-Year Moored Record (1999–2009)
