Numerical prediction of ice rubble field loads on the Norströmsgrund lighthouse using cohesive element formulation
(Peer reviewed; Journal article, 2021)An attempt has been made to predict the ice rubble field load on Norströmsgrund lighthouse by using Cohesive Element (CE) formulation. Two sub-load events were selected to validate the numerical and material model used in ... -
Simulation of brash ice behaviour in the Gulf of Bothnia using Smoothed Particle 1 Hydrodynamics formulation
(Peer reviewed; Journal article, 2021)The repeated passage of ships through ice-infested waters create a field of broken ice pieces. The typical size of the broken ice pieces is generally <2.0 m. This area might be referred to as a brash ice field. The movement ... -
A comparison between laser, scanning, photogrammetry and infrared scanning to create 3D digital models of existing concrete bridges
(Chapter, 2020)Routine bridge inspections usually consist of visual observations. These inspections are time-consuming and subjective. There is a need to identify new inspection techniques for infrastructure that reduce traffic disturbance, ... -
Physical and mechanical properties of ice from a refrozen ship channel ice in Bay of Bothnia
(Chapter, 2020)Winter navigation in the North Sea is expanding with respect to vessel size and traffic volume. Icebreakers create routes for ice-going vessels by breaking the level ice cover. Repeated vessel passages in the fairways and ... -
Ice Formation in Norwegian Fjords – Findings from the 2018 - 2019 Field Season
(Chapter, 2020)Understanding ice conditions in fjords is imperative to ensure safe operations and to protect the surrounding environment. Seven fjords in northern Norway were visited in March 2019, six with significant ice cover. In each ... -
A Note on Remote Temperature Measurements with DS18B20 Digital Sensors
(Chapter, 2020)Digital temperature sensors provide an attractive means to conveniently record ice and water temperatures in remote locations. Unlike conventional analogue techniques, a digital sensor performs a physical measurement, ... -
From above and standing atop- two views of Norwegian fjord ice

Numerical analysis of ice loads on Taraldsvikfossen dam
(Chapter, 2020)Static ice loads (ice actions) are a key design parameter for dams in cold climates. Since 2012,ice stresses have been measured at Taraldsvikfossen reservoir located in Narvik, Norway. Similar to earlier observations in ... -
Static ice loads on a dam in a small Norwegian reservoir
(Chapter, 2020)Ice loads on a concrete dam have been calculated from stress measurements in Taraldsvikfossen Reservoir, a small reservoir in Narvik, Norway, during three winter seasons. Ice thickness was in the range of 0.5 to 1.0 m, and ... -
Biotransformation of chemically dispersed diesel at sub-zero temperatures using artificial brines
(Peer reviewed; Journal article, 2020)The biotransformation of hydrocarbon compounds in seawater at sub-zero temperature has gained research interest in recent years with the most focus placed on temperatures around 0°C. In this study, biotransformation of ... -
Ice extent in sub-arctic fjords and coastal areas from 2001 to 2019 analyzed from MODIS imagery
(Peer reviewed; Journal article, 2020)Results examining variations in the ice extent along the Norwegian coastline based on the analysis of Moderate Resolution Imaging Spectroradiometer (MODIS) images from 2001 to 2019,February through May, are presented. A ... -
3D graphene aerogel framework enwrapped LiFePO4 submicron-rods with improved lithium storage performance
(Journal article; Peer reviewed, 2019)The three-dimensional (3D) graphene aerogel (GA)-wrapped LiFePO4 submicron-rod composite (LFP@GA) has been prepared successfully through a solvothermal method followed with rapid freezedrying. Monodispersed LiFePO4 ... -
Crude oil migration in sea-ice: Laboratory studies of constraints on oil mobilization and seasonal evolution
(Journal article; Peer reviewed, 2019)Rising Arctic maritime activities and hydrocarbon development increase the risk of an oil spill in and under Arctic sea-ice. Oil spilled under growing sea ice would be encapsulated within the ice cover. During spring and ...
