ESD Reviews: Climate feedbacks in the Earth system and prospects for their evaluation
(Peer reviewed; Journal article, 2019)Earth system models (ESMs) are key tools for providing climate projections under different scenarios of human-induced forcing. ESMs include a large number of additional processes and feedbacks such as biogeochemical cycles ... -
Essays on Portfolio Risk Management and Weather Derivatives
(Doctoral thesis, 2023-08-25)Denne avhandlingen handler om utvikling og praktisk implementering av risikostyringsmetoder for investeringsporteføljer, energiporteføljer, og håndtering av vær- og forurensningsrisiko. Avhandlingen inkluderer tre ... -
Establishing a homogeneous and stable sand pack to study parameters during spontaneous imbibition
(Master thesis, 2018-06-20)Spontaneous imbibition is an important process for oil production during water flooding in porous media and has been widely studied for decades to understand the physics of the process for different boundary conditions. ... -
Establishing fin whale fibroblast culture conditions for toxicological studies
(Master thesis, 2022-10-03)Several marine mammal species have been hunted to near extinction by humans. As such, many of these species are vulnerable to population reductions due to changing climate, destruction of habitats, and environmental ... -
Establishing reward systems for excellence in teaching – the experience of academics pioneering a reward system
(Journal article; Peer reviewed, 2023)Higher education institutions are struggling to elevate the value and status of academic teaching. In this endeavour, rewards for excellence in teaching are becoming a common measure. This study reports on the experience ... -
Establishment of killer whale (Orcinus orca) primary fibroblast cell cultures and their transcriptomic responses to pollutant exposure
(Journal article; Peer reviewed, 2023)Populations of killer whale (Orcinus orca) contain some of the most polluted animals on Earth. Yet, the knowledge on effects of chemical pollutants is limited in this species. Cell cultures and in vitro exposure experiments ... -
Establishment of Pinus wallichiana on a Himalayan glacier foreland: stochastic distribution or safe sites?
(Peer reviewed; Journal article, 2006)The establishment of tree seedlings in primary succession is thought to occur only after an adequate reserve of nutrients has accumulated in the soil. Individuals of Pinaceae are sometimes reported to grow on very recently ... -
Estimating a mean transport velocity in the marginal ice zone using ice-ocean prediction systems
(Journal article; Peer reviewed, 2022)Understanding the transport of objects and material in the marginal ice zone (MIZ) is critical for human operations in polar regions. This can be the transport of pollutants, such as spilled oil, or the transport of objects, ... -
Estimating fin whale distribution from ambient noise spectra using Bayesian inversion
(Master thesis, 2015-06-01)Passive acoustic monitoring is increasingly used to study the distribution and migration of marine mammals. Marine mammal vocalizations are transient sounds, but the combined sound energy of a population continuously ... -
Estimating Fish Densities from Single Fish Echo Traces
(Peer reviewed; Journal article, 2009)Estimating mean fish density per unit area has been done by counting single fish echo traces with a split beam echo sounder system in the open sea. A data program has been written that scans the acoustic signals for echo ... -
Estimating genetic diversity in a domesticated population of Norwegian Atlantic salmon (Salmo salar) using genomic data
(Master thesis, 2017-12-15)New developments of high throughput sequencing technologies have allowed for breeders to assess values related to loss of genetic diversity in domesticated animals on a genomic level for better accuracy than the pedigree ... -
Estimating global artisanal fishing fleet responses in an era of rapid climate and economic change
(Journal article; Peer reviewed, 2023)There is an urgent need to assess the extent to which the global fishing enterprise can be sustainable in the face of climate change. Artisanal fishing plays a crucial role in sustaining livelihoods and meeting food security ... -
Estimating global radiation at ground level from satellite images

Estimating the discretization dependent accuracy of perfusion in coupled capillary flow measurements
(Peer reviewed; Journal article, 2018-07-20)One-compartment models are widely used to quantify hemodynamic parameters such as perfusion, blood volume and mean transit time. These parameters are routinely used for clinical diagnosis and monitoring of disease development ... -
Estimating the fate of oxygen ion outflow from the high-altitude cusp
(Journal article; Peer reviewed, 2020)We have investigated the oxygen escape-to-capture ratio from the high-altitude cusp regions for various geomagnetic activity levels by combining EDI and CODIF measurements from the Cluster spacecraft. Using a magnetic field ... -
Estimating the Rate of Cessation of Magnetospheric Activity in AMPERE Field‐Aligned Currents
(Peer reviewed; Journal article, 2018-12)The decay of magnetospheric activity when driving is turned off (to a minimum) was measured in total field‐aligned current estimates from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) ... -
Estimating the size of undetected cases of the COVID-19 outbreak in Europe: An upper bound estimator
(Journal article; Peer reviewed, 2020)Background While the number of detected COVID-19 infections are widely available, an understanding of the extent of undetected cases is urgently needed for an effective tackling of the pandemic. The aim of this work is ... -
Estimating the undetected infections in the Covid-19 outbreak by harnessing capture-recapture methods
(Journal article; Peer reviewed, 2020)Objectives A major open question, affecting the decisions of policy makers, is the estimation of the true number of Covid-19 infections. Most of them are undetected, because of a large number of asymptomatic cases. We ... -
Estimating the volume of the 1978 Rissa quick clay landslide in Central Norway using historical aerial imagery
(Journal article; Peer reviewed, 2022)Quick clay is found across Scandinavia and is especially prominent in south-eastern and central Norway. Quick clay is prone to failure and can cause landslides with high velocities and large run-outs. The 1978 Rissa landslide ...
