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 ... -
The 2021 Atlantic Niño and Benguela Niño Events: external forcings and air–sea interactions
(Journal article; Peer reviewed, 2023)This paper presents a comprehensive analysis of the extreme Atlantic and Benguela Niño events that occurred during the boreal spring–summer of 2021. We conducted sensitivity experiments with a regional ocean–atmosphere ... -
On dynamical downscaling of ENSO-induced oceanic anomalies off Baja California Peninsula, Mexico: role of the air-sea heat flux
(Journal article; Peer reviewed, 2023)The El Niño Southern Oscillation (ENSO) phenomenon is responsible for important physical and biogeochemical anomalies in the Northeastern Pacific Ocean. The event of 1997-98 has been one of the most intense in the last ... -
Mind the gap – Relevant design for laboratory oil exposure of fish as informed by a numerical impact assessment model
(Journal article; Peer reviewed, 2023)Laboratory experiments provide knowledge of species-specific effects thresholds that are used to parameterize impact assessment models of oil contamination on marine ecosystems. Such experiments typically place individuals ... -
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. ... -
FLIIMP - a community software for the processing, calibration, and reporting of liquid water isotope measurements on cavity-ring down spectrometers
(Journal article; Peer reviewed, 2023)Precise and accurate measurements of the stable isotope composition from precipitation, land ice, runoff, and oceans provide critical information on Earth's water cycle. The analysis, post-processing, and calibration of ... -
Decadal Trends in the Oceanic Storage of Anthropogenic Carbon From 1994 to 2014
(Journal article; Peer reviewed, 2023)The oceanic uptake and resulting storage of the anthropogenic CO2 (Cant) that humans have emitted into the atmosphere moderates climate change. Yet our knowledge about how this uptake and storage has progressed in time ... -
Enhancing Seasonal Forecast Skills by Optimally Weighting the Ensemble from Fresh Data
(Journal article; Peer reviewed, 2023)Dynamical climate predictions are produced by assimilating observations and running ensemble simulations of Earth system models. This process is time consuming and by the time the forecast is delivered, new observations ... -
Trapped tidal currents generate freely propagating internal waves at the Arctic continental slope
(Journal article; Peer reviewed, 2023)Energetic tidal currents in the Arctic play an important role in local mixing processes, but they are primarily confined to the shelves and continental slopes due to topographic trapping north of their critical latitude. ... -
Rapid fCO2 rise in the northern Barents Sea and Nansen Basin
(Journal article; Peer reviewed, 2023)Maps of surface water fugacity of CO2 (fCO2) over eastern Fram Strait, south-western Nansen Basin, and the north-western Barents Sea (73–84°N, 5–46°E) from September 1997 to December 2020 were made and used to investigate ...
