Simulert Dynamisk Atmosfærerespons til Endringer i Arktisk Sjøisdekke
(Master thesis, 2003) -
Single CO2 drops in seawater
(Master thesis, 2004)To mitigate the increasing atmospheric CO2 level and reduce the subsequent impacts, storage of CO2 is one option that might become necessary. Ocean storage and storage of CO2 under the sea bottom with potential leakage ... -
Skier stability index - An additional tool for snow avalanche forecasting in Norway?
(Master thesis, 2018-06-16)With more people running to the mountains for skiing backcountry terrain, the need for a good snow avalanche forecast is dire. Todays forecast is based on the weather forecast, snow observations by professional observers ... -
Skilful decadal-scale prediction of fish habitat and distribution shifts
(Journal article; Peer reviewed, 2022)Many fish and marine organisms are responding to our planet’s changing climate by shifting their distribution. Such shifts can drive international conflicts and are highly problematic for the communities and businesses ... -
Skilful prediction of cod stocks in the North and Barents Sea a decade in advance
(Journal article; Peer reviewed, 2021)Reliable information about the future state of the ocean and fish stocks is necessary for informed decision-making by fisheries scientists, managers and the industry. However, decadal regional ocean climate and fish stock ... -
Skillful prediction of Barents Sea ice cover
(Peer reviewed; Journal article, 2015-07-08)A main concern of present climate change is the Arctic sea ice cover. In wintertime, its observed variability is largely carried by the Barents Sea. Here we propose and evaluate a simple quantitative and prognostic framework ... -
Skillful prediction of northern climate provided by the ocean
(Peer reviewed; Journal article, 2017-06-20)It is commonly understood that a potential for skillful climate prediction resides in the ocean. It nevertheless remains unresolved to what extent variable ocean heat is imprinted on the atmosphere to realize its predictive ... -
Small-scale dynamics of the under-ice boundary layer
(Doctoral thesis, 2009-01-09)In ice covered polar regions, the interaction between ocean, ice and atmosphere is an important component in the complex climate system. Exchange of heat, mass and momentum occurs across the boundary layers, both in the ... -
Small-scale turbulence dynamics under sea surface gravity waves
(Doctoral thesis, 2014-08-20)The ocean surface is a complex boundary where air-sea fluxes of mass, momentum and energy take place. The processes at this dynamic interface are of great importance in the coupled atmosphere-ocean system. The coupling ... -
A Snapshot on the Buildup of the Stable Water Isotopic Signal in the Upper Snowpack at EastGRIP on the Greenland Ice Sheet
(Journal article; Peer reviewed, 2023)The stable water isotopic composition in firn and ice cores provides valuable information on past climatic conditions. Because of uneven accumulation and post-depositional modifications on local spatial scales up to hundreds ... -
Snow-Atmosphere Humidity Exchange at the Ice Sheet Surface Alters Annual Mean Climate Signals in Ice Core Records
(Journal article; Peer reviewed, 2023)Surface processes alter the water stable isotope signal of the surface snow after deposition. However, it remains an open question to which extent surface post-depositional processes should be considered when inferring ... -
Snowfall and Water Stable Isotope Variability in East Antarctica Controlled by Warm Synoptic Events
(Journal article; Peer reviewed, 2020)Understanding climate proxy records that preserve physical characteristics of past climate is a prerequisite to reconstruct long-term climatic conditions. Water stable isotope ratios (δ18O) constitute a widely used proxy ... -
Snowfall in the Himalayas: An uncertain future from a little-known past
(Peer reviewed; Journal article, 2015-06-03)Snow and ice provide large amounts of meltwater to the Indus, Ganges and Brahmaputra rivers. This study combines present-day observations and reanalysis data with climate model projections to estimate the amount of snow ... -
A Solar Absorber Based on Metal Nanoparticles
(Master thesis, 2016-06-01)Metal nanoparticles (MNPs) exhibits unique optical properties often found in the visible spectrum of light. The key point of interest is the so-called Localized Surface Plasmon Resonance (LSPR) effect that arises within ... -
Solar forcing synchronizes decadal North Atlantic climate variability
(Peer reviewed; Journal article, 2015-09-15)Quasi-decadal variability in solar irradiance has been suggested to exert a substantial effect on Earth’s regional climate. In the North Atlantic sector, the 11-year solar signal has been proposed to project onto a pattern ... -
Solar-wind–magnetosphere energy influences the interannual variability of the northern-hemispheric winter climate
(Journal article; Peer reviewed, 2020)Solar irradiance has been universally acknowledged to be dominant by quasi-decadal variability, which has been adopted frequently to investigate its effect on climate decadal variability. As one major terrestrial energy ... -
Solstrøm, kraftnett, energimodeller og World Energy Model - Hvorfor undervurderes utbygging av solstrøm av IEAs WEM-modell?
(Master thesis, 2016-06-01)I denne oppgaven har jeg forsøkt å svare på spørsmålet «Hvorfor undervurderes utbygging av solstrøm i IEAs WEM-modell?». Dette har jeg gjort ved å se på hvilken teori og ny forskning som finnes for solkraft, kraftsystem, ... -
Some aspects of the work of V.W. Ekman
(Journal article, 2006-01)The climatic conditions in theArctic, and observations of the wind-induced drift of ice made in connexion with Fridtjof Nansen’s Fram expedition, led to the discovery 100 years ago by Vilhelm Bjerknes’ pupil, V.W. Ekman, ... -
Sources and upstream pathways of the densest overflow water in the Nordic Seas
(Journal article; Peer reviewed, 2020)Overflow water from the Nordic Seas comprises the deepest limb of the Atlantic Meridional Overturning Circulation, yet questions remain as to where it is ventilated and how it reaches the Greenland-Scotland Ridge. Here we ... -
Southern Ocean Control of 2°C Global Warming in Climate Models
(Journal article; Peer reviewed, 2023)Global warming will soon reach the Paris Agreement targets of 1.5°C/2°C temperature increase above pre-industrial levels. Under a business-as-usual scenario, the time to reach these targets varies widely among climate ...
