Atlantic water inflow into the Arctic Ocean: studies of pathways, transport and mixing processes using observations from ships and autonomous underwater vehicles
(Doctoral thesis, 2024-01-23)Nordishavet spiller en viktig rolle i det globale klimasystemet. Produksjon av kaldt vann med høy tetthet, samt frysing av sjøis i Arktis, bidrar til å drive den Atlantiske meridionale omveltningssirkulasjonen og kan påvirke ... -
Disko Bay sea-ice variability: Oceanic and Atmospheric drivers
(Master thesis, 2023-11-20)Climate change impacts the Arctic sea-ice cover and thickness with a related Arctic Amplification and an increased ocean heat transport towards the Arctic. There has been a profound decline of Arctic winter sea-ice extent, ... -
On the use of a new mathematical formulation for loads- and motion analysis of a mooring line
(Master thesis, 2023-11-20)This master thesis investigates the use of a new mathematical model for calculating loads and dynamic motion of a mooring line. Current industry standard mooring analysis tools uses a lumped parameter modelling approach. ... -
Optimal location of charging stations for electric vehicles
(Master thesis, 2023-11-20)The electrification of road transportation requires a massive investment in charging infrastructure to keep up with the demand for underway charging. A substantial research effort is put into the problem of finding optimal ... -
IWIN: the Isfjorden Weather Information Network
(Journal article; Peer reviewed, 2023)In an effort led by the University Centre in Svalbard (UNIS), with support from the Norwegian Meteorological Institute (MET Norway), the Isfjorden Weather Information Network (IWIN) is under development in the Isfjorden ... -
ENSO teleconnections in terms of non-NAO and NAO atmospheric variability
(Journal article; Peer reviewed, 2023)The validity of the long-held understanding or assumption that El Niño-Southern Oscillation (ENSO) has a remote influence on the North Atlantic Oscillation (NAO) in the January–February–March (JFM) months has been questioned ... -
Seasonality of coastal upwelling trends in the Mauritania-Senegalese region under RCP8.5 climate change scenario
(Journal article; Peer reviewed, 2023)The Mauritania-Senegalese upwelling region (MSUR), the southernmost region of the Canary current upwelling system, is well-known for its coastal productivity and the key role it plays in enriching the oligotrophic open ... -
Prediction of Harmful Algae Blooms Impacting Shellfish Farms in Norway
(Doctoral thesis, 2023-11-30)Skadelig algeoppblomstring (HAB) forårsaker alvorlig skade på økosystemet og menneskers helse, samt økonomiske konsekvenser for skalldyr og oppdrettsanlegg. Utviklingen av HABs prediksjonsmodeller har blitt økenende populart ... -
Surface-Forced Variability in the Nordic Seas Overturning Circulation and Overflows
(Journal article; Peer reviewed, 2023)Water mass transformation in the Nordic Seas and the associated overflow of dense waters across the Greenland-Scotland Ridge (GSR) acts to maintain the lower limb of the Atlantic meridional overturning circulation. Here, ... -
On the Freshwater Transport in the Fram Strait
(Doctoral thesis, 2023-11-03)Ferskvann fra Arktisk er en nøkkelparameter i det globale klimasystemet. Arktisk ferskvann har sin opprinnelse fra nedbør eller havis-smelting, og konsentrasjonen av det i havet varierer på flere tidsskalaer. Økningen i ... -
Dispersion of Mine Particles in Førdefjorden
(Master thesis, 2023-10-10)Førdefjorden is the site of a newly permitted submarine tailing disposal (STD) in Norway, and it is nationally debated. Major implications of an STD can be toxic compounds of the tailing, severe impacts on the benthic ... -
Arctic-Atlantic Climate Variability and Predictability in Observations and in a Dynamical Prediction System
(Doctoral thesis, 2023-11-03)Hovedfokuset i denne doktorgradsoppgaven er å forstå dekadisk klimaprediktabilitet (forutsigbarhet i klimaet) for å forbedre klimamodeller og klimavarsel. Klimavarseling viser lovende resultat, men det er fremdeles ... -
Warming beneath an East Antarctic ice shelf due to increased subpolar westerlies and reduced sea ice
(Journal article; Peer reviewed, 2023)Understanding how climate change influences ocean-driven melting of the Antarctic ice shelves is one of the greatest challenges for projecting future sea level rise. The East Antarctic ice shelf cavities host cold water ... -
On the Use of Dual Co-Polarized Radar Data to Derive a Sea Surface Doppler Model - Part 2: Simulation and Validation
(Journal article; Peer reviewed, 2023)The Doppler shift obtained from synthetic aperture radar (SAR) measurements comprises the combined contribution to the radial motion of the ocean surface induced by the sea state (wind waves and swell) and underlying surface ... -
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 ... -
Intraseasonal and synoptic modulation of diurnal surface solar radiation over Reunion island in the South-West Indian Ocean
(Journal article; Peer reviewed, 2023)Understanding the space-time variability of Surface Solar Radiation (SSR) is mandatory for the prediction and, eventually, the skillful forecasting of photovoltaic energy production. This paper addresses the modulation of ... -
Contrasting responses of the ocean’s oxygen minimum zones to artificial re-oxygenation
(Journal article; Peer reviewed, 2023)Studies assessing potential measures to counteract the marine deoxygenation attributed to anthropogenic activities have been conducted in a few coastal environments and at regional scale, but not yet on a global scale. One ... -
Deconstructing Future AMOC Decline at 26.5°N
(Journal article; Peer reviewed, 2023)The Atlantic Meridional Overturning Circulation (AMOC) is frequently used to diagnose the state of the North Atlantic circulation, but as an integrated quantity the AMOC strength does not necessarily mirror changes in the ... -
On the Origins of Open Ocean Oxygen Minimum Zones
(Journal article; Peer reviewed, 2023)Recent work suggests that Oxygen Minimum Zones (OMZs) are sustained by the supply of oxygen-poor waters rather than the export of organic matter from the local surface layer and its subsequent remineralization inside OMZs. ... -
