Evaluation of a sub-kilometre NWP system in an Arctic fjord-valley system in winter
(Journal article; Peer reviewed, 2020)Terrain challenges the prediction of near-surface atmospheric conditions, even in kilometre-scale numerical weather prediction (NWP) models. In this study, the ALADIN-HIRLAM NWP system with 0.5 km horizontal grid spacing ... -
Evaluation of analytical strategies for quantifying selected polyphenols in feed production: from ingredient to fish.
(Master thesis, 2023-09-30)Polyphenols are an extensive group of compounds with important antioxidant properties, whose industrial use has shown a continuous increase in the last years. Their utilization in aquaculture is becoming progressively ... -
Evaluation of black soldier fly larvae meal as a functional feed ingredient in Atlantic salmon (Salmo salar) under farm-like conditions
(Journal article; Peer reviewed, 2023)Atlantic salmon (Salmo salar) were fed diets containing black soldier fly larvae (BSFL) meal at two inclusion levels for 13 months in open sea-cages. BSFL meal replaced plant-based ingredients and dietary insect meal ... -
Evaluation of different wind fields for the investigation of the dynamic response of offshore wind turbines
(Journal article; Peer reviewed, 2020)As the size of offshore wind turbines increases, a realistic representation of the spatiotemporal distribution of the incident wind field becomes crucial for modeling the dynamic response of the turbine. The International ... -
Evaluation of Gaussian wake models under different atmospheric stability conditions: Comparison with large eddy simulation results
(Journal article; Peer reviewed, 2020)The calculation of the velocity deficit in the wake of individual wind turbines is a fundamental part of the wind farm analysis. A good approximation of the wake deficit behind a single wind turbine will improve the power ... -
Evaluation of harvest control rules: simple one-parameter versus complex multi-parameter strategies
(Master thesis, 2004)Harvest control rules (HCR) are sets of well-defined rules that can be used for determining annual fish catch quotas or effort. If a management policy can be expressed as a HCR, then the HCR provides means to determine the ... -
Evaluation of Methane and Water Structure at a Hematite Surface - A Hydrate Prevention Perspective
(Master thesis, 2017-09-25)In Norway oil and gas is found in reservoirs below the North Sea and the Barents Sea. When this is transported through pipelines it is exposed to temperatures and pressures in the hydrate stability zone. If sufficient ... -
Evaluation of ocean dimethylsulfide concentration and emission in CMIP6 models
(Journal article; Peer reviewed, 2021)Characteristics and trends of surface ocean dimethylsulfide (DMS) concentrations and fluxes into the atmosphere of four Earth system models (ESMs: CNRM-ESM2-1, MIROC-ES2L, NorESM2-LM, and UKESM1-0-LL) are analysed over the ... -
Evaluation of photodegradable chitin synthetase inhibitors for the treatment of salmon lice (Lepeophtheirus salmonis)
(Journal article; Peer reviewed, 2023)Some photolabile ethanolamine analogues of the chitin synthetase inhibitors diflubenzuron, teflubenzuron, and lufenuron were tested for activity as anti-lice compounds towards salmon lice (Lepeophtheirus salmonis). Two ... -
Evaluation of potential reference genes in real-time RT-PCR studies of Atlantic salmon
(Peer reviewed; Journal article, 2005)Background: Salmonid fishes are among the most widely studied model fish species but reports on systematic evaluation of reference genes in qRT-PCR studies is lacking. Results: The stability of six potential reference genes ... -
An evaluation of surface meteorology and fluxes over the Iceland and Greenland Seas in ERA5 reanalysis: The impact of sea ice distribution
(Journal article; Peer reviewed, 2021)The Iceland and Greenland Seas are a crucial region for the climate system, being the headwaters of the lower limb of the Atlantic Meridional Overturning Circulation. Investigating the atmosphere–ocean–ice processes in ... -
Evaluation of Temperature-Dependent Complex Refractive Indices of Supercooled Liquid Water Using Downwelling Radiance and In-Situ Cloud Measurements at South Pole
(Journal article; Peer reviewed, 2022)Clouds have a large effect on the radiation budget and represent a major source of uncertainty in climate models. Supercooled liquid clouds can exist at temperatures as low as 235 K, and the radiative effect of these clouds ... -
Evaluation of the dynamic core of the PALM model system 6.0 in a neutrally stratified urban environment: comparison between LES and wind-tunnel experiments
(Journal article; Peer reviewed, 2021)We demonstrate the capability of the PALM model system version 6.0 to simulate neutrally stratified urban boundary layers. Our simulation uses the real-world building configuration of the HafenCity area in Hamburg, Germany. ... -
An Evaluation of the EnKF vs. EnOI and the Assimilation of SMAP, SMOS and ESA CCI Soil Moisture Data over the Contiguous US
(Peer reviewed; Journal article, 2019-02-26)A number of studies have shown that assimilation of satellite derived soil moisture using the ensemble Kalman Filter (EnKF) can improve soil moisture estimates, particularly for the surface zone. However, the EnKF is ... -
Evaluation of the Field Kelvin Probe for non-intrusive condition monitoring of concrete reinforcements
(Master thesis, 2020-04-24)Early detection of corrosion in reinforced concrete is of great importance for safe operation of the concrete based infrastructure we rely on such as bridges and large buildings. Undetected corrosion in the steel reinforcements ... -
An evaluation of the performance of sea ice thickness forecasts to support arctic marine transport
(Journal article; Peer reviewed, 2022)In response to declining sea ice cover, human activity in the Arctic is increasing, with access to the Arctic Ocean becoming more important for socio-economic reasons. Accurate knowledge of sea ice conditions is therefore ... -
Evaluation of three numerical weather prediction models for the Weddell Sea region for the Austral winter 2013
