The circulation of the Norwegian Sea- An investigation from space and ocean
(Doctoral thesis, 2014-01-10)The Norwegian Sea circulation plays a key role in maintaining the mild climate of the northwestern Europe via the transport of warm Atlantic Water pole-ward. The first paper addresses the advective currents connecting the ... -
Climate controlled mechanisms of subpolar North Atlantic carbon uptake
(Doctoral thesis, 2017-06-27)The North Atlantic is a key region for global climate variability. Earlier studies have shown changes in the large-scale circulation, air-sea heat and freshwater fluxes and the carbon cycle in the North Atlantic in relation ... -
Connecting the drops: Exploring precipitation changes from a process and weather perspective
(Doctoral thesis, 2024-03-22)Nedbør er kilden til en av de viktigste ressursene for mennesker: ferskvann. På den andre siden kan ekstremnedbør utgjøre en trussel i form av flom og skred. Det er derfor avgjørende å fastslå hvordan nedbøren har forandret ... -
Connectivity among subpopulations of Norwegian Coastal cod. Impacts of physical-biological factors during egg stages.
(Doctoral thesis, 2012-04-19)Norwegian Coastal cod form a stationary population of Atlantic cod ( Gadus morhua L.) consisting of several genetically separated subpopulations. A small-scale differen- tiation in marine populations with pelagic eggs and ... -
Dealing with uncertainty in ecosystem models along three axes; resolution, forcing and projections
(Doctoral thesis, 2023-05-24)With the imminent threat of climate change, there is an urgent need to understand how warmer temperatures will affect marine ecosystems. Models provide the best tools to study the future, but although great efforts have ... -
Decadal solar irradiance variability in northern Europe
(Doctoral thesis, 2014-11-28)Shortwave (SW) radiation from the Sun is the external energy source on Earth and the fundamental input of energy into the climate system. Variations of the SW radiation and its transfer through the atmosphere can have ... -
Developing the Tools to Quantify Past Climate Variability from Ice Core Records
(Doctoral thesis, 2023-06-21)Vannstabile isotoper registrert i iskjerner, brukes som proxydata for å rekonstruere klimaet i fortiden. Tradisjonell tolkning av registrerte vannisotoper er at snø fanger opp den integrerende isotopiske signaturen av ... -
Drivers of the marine CO2 system in the High Arctic - from the deep basins to the shallow fjords
(Doctoral thesis, 2019-02-20)The High Arctic is largely undersampled in terms of marine CO2 system data due to the cold dark season and often an extensive sea ice cover. The current understanding of the Arctic carbon cycle is thus vulnerable to both ... -
Dynamical Perspectives on the Formation and Intensification of Polar Lows
(Doctoral thesis, 2014-11-25)This thesis consists of a collection of scientific publications addressing dynamical aspects of the formation and intensification of polar lows. Polar lows are small scale, intense, short-lived cyclones developing over ... -
Ensemble-based data assimilation and forecasting with an eddy-resolving model of the Gulf of Mexico
(Doctoral thesis, 2008-09-12) -
Estimating global radiation at ground level from satellite images
(Doctoral thesis, 2005-06-15) -
Exchange of water masses between the southern Weddell Sea continental shelf and the deep ocean
(Doctoral thesis, 2018-06-13)The exchange of water masses between the shallow Weddell Sea continental shelf and the deep ocean is of climatic importance. Firstly, on-shelf transport of warm oceanic water masses, contributes to basal melting of ice ... -
Exploring Arctic-midlatitude teleconnections using observations and numerical models
(Doctoral thesis, 2021-05-27)The Arctic is warming at a much faster rate than the rest of the globe, with large declines in sea ice, snow cover and permafrost over the last decades. These profound changes have been proposed to influence the midlatitude ... -
Extreme Precipitation in Nepal. Trends and Key Processes
(Doctoral thesis, 2018-03-21)Nepal is located at the rim of the Himalayas and houses the highest mountains of the world. Owing to the complex topography and a seasonal monsoon climate, Nepal experiences precipitation events of considerable intensity. ... -
Extreme winds in the Nordic Seas : polar lows and Arctic fronts in a changing climate
(Doctoral thesis, 2007-03-30) -
Extremes and Trends in Wave Climate. A regional and global study
(Doctoral thesis, 2015-01-16)Wind generated surface waves represent a critical factor for offshore constructions and coastal development, and are highly relevant in scientific questions related to climate and weather. The sea state can be described ... -
Formation and pathways of dense water in the Nordic Seas
(Doctoral thesis, 2023-10-20)Sammendrag De nordiske hav er viktig for dannelsen av kalde, tette og dype vannmasser som strømmer sørover på tvers av Grønland-Skottland-ryggen og forsyner den dype grenen av omveltningssirkulasjonen i Atlanterhavet. På ... -
High resolution sea ice monitoring using space borne Synthetic Aperture Radar
(Doctoral thesis, 2017-12-06)Sea ice represents a major factor in the climate system and updated knowl- edge about sea ice conditions is important for shipping and offshore industry, local communities and others. Due to its remote location and strong ... -
