The impact of mean state errors on equatorial Atlantic interannual variability in a climate model
(Peer reviewed; Journal article, 2015-02-23)Observations show that the Equatorial Atlantic Zonal Mode (ZM) obeys similar physics to the El Niño Southern Oscillation (ENSO): positive Bjerknes and delayed negative feedbacks. This implies the ZM may be predictable on ... -
The impact of micro-mineral sources and their availability on hepatic lipid metabolism in Atlantic salmon (Salmo salar)
(Master thesis, 2018-06-27)The increased use of plant-based ingredients in aquafeeds for Atlantic salmon has led to an increase in phytate, an antinutrient binding micro minerals and reducing their bioavailability. It has been suggested that the ... -
Impact of Nitrogen Deposition on Species Richness and Species Composition of Ombrotrophic Mires in Western Norway
(Master thesis, 2013-07-09)There is almost no research on ombrotrophic mire vegetation and the possible impact of atmospheric nitrogen deposition on species richness and composition in Norway. It is important to detect whether N deposition is impacting ... -
Impact of normal faulting and pre-rift salt tectonics on the structural style of salt-influenced rifts: the Late Jurassic Norwegian Central Graben, North Sea
(Peer reviewed; Journal article, 2017-10)Studies of salt‐influenced rift basins have focused on individual or basin‐scale fault system and/or salt‐related structure. In contrast, the large‐scale rift structure, namely rift segments and rift accommodation zones ... -
Impact of ocean and sea ice initialisation on seasonal prediction skill in the Arctic
(Peer reviewed; Journal article, 2019)There is a growing demand for skillful prediction systems in the Arctic. Using the Norwegian Climate Prediction Model (NorCPM) that combines the fully-coupled Norwegian Earth System Model and the Ensemble Kalman filter, ... -
The Impact of Oxygen on the Reconnection Rate
(Peer reviewed; Journal article, 2019-05-29)We investigate the role of a background oxygen population in magnetic reconnection, using particle‐in‐cell simulations. We run several simulations, with different initial oxygen temperatures and densities, to understand ... -
Impact of parents' education on variation in hospital admissions for children: a population-based cohort study
(Journal article; Peer reviewed, 2021)Objectives To assess the impact of parental educational level on hospital admissions for children, and to evaluate whether differences in parents' educational level can explain geographic variation in admission rates. ... -
Impact of physical obstacles on the structural and effective connectivity of in silico neuronal circuits
(Journal article; Peer reviewed, 2020)Scaffolds and patterned substrates are among the most successful strategies to dictate the connectivity between neurons in culture. Here, we used numerical simulations to investigate the capacity of physical obstacles ... -
The Impact of Pre‐Salt Rift Topography on Salt Tectonics: A Discrete‐Element Modeling Approach
(Peer reviewed; Journal article, 2019)Gravity‐driven salt tectonics along passive margins is commonly depicted as comprising domains of updip extension and downdip contraction linked by an intermediate, broadly undeformed zone of translation. This study expands ... -
The Impact of Rheology on Viscous Oil Displacement by Polymers Analyzed by Pore-Scale Network Modelling
(Journal article; Peer reviewed, 2021)Several experimental studies have shown significant improvement in heavy oil recovery with polymers displaying different types of rheology, and the effect of rheology has been shown to be important. These experimental ... -
Impact of runoff temporal distribution on ice dynamics
(Journal article; Peer reviewed, 2022)Record highs of meltwater production at the surface of the Greenland ice sheet have been recorded with a high recurrence over the last decades. Those melt seasons with longer durations, larger intensities, or with both ... -
Impact of sea ice transport on Beaufort Gyre liquid freshwater content
(Journal article; Peer reviewed, 2023)The Arctic Ocean’s Beaufort Gyre (BG) is a wind-driven reservoir of relatively fresh seawater, situated beneath time-mean anticyclonic atmospheric circulation, and is covered by mobile pack ice for most of the year. Liquid ... -
Impact of seasonal fluctuations of ice velocity on decadal trends observed in Southwest Greenland
(Journal article; Peer reviewed, 2023)By tracking the feature displacement between satellite images spaced approximately one year apart, surface runoff has been shown to have a long-term impact on the average ice flow of a land-terminating sector of Greenland. ... -
Impact of Snow Initialization in Subseasonal‐to‐Seasonal Winter Forecasts With the Norwegian Climate Prediction Model
(Peer reviewed; Journal article, 2019)Snow initialization has been previously investigated as a potential source of predictability atthe subseasonal‐to‐seasonal (S2S) timescale in winter and spring, through its local radiative,thermodynamical, and hydrological ... -
Impact of solar irradiance and geomagnetic activity on polar NOx, ozone and temperature in WACCM simulations
(Journal article; Peer reviewed, 2020)The response of the atmosphere to solar irradiance and geomagnetic activity is analyzed in experiments with the Whole Atmosphere Community Climate Model (WACCM) under idealized forcings. Four experiments are carried out ... -
Impact of space weather on the polar atmosphere
(Master thesis, 2020-07-01)The impact of the Chemical-Dynamical coulping and the Mansurov effect are examined. Statistical correlations are found for both mechanisms. The possibility of an aliasing effect being responsible for the obtained significance ... -
