Norwegian offshore wind power—Spatial planning using multi-criteria decision analysis
(Journal article; Peer reviewed, 2023)The Norwegian government recently agreed on the goal 30by40, which involves opening Norwegian offshore areas to host 30 GW of installed wind power by 2040. We address this goal by presenting a first mapping of wind power ... -
A Regime View of ENSO Flavors Through Clustering in CMIP6 Models
(Journal article; Peer reviewed, 2023)El Niño-Southern Oscillation (ENSO) flavors in the tropical Pacific are studied from a regime perspective. Five recurring spatial patterns or regimes characterizing the diversity of ENSO are established using a clustering ... -
Riverine impact on future projections of marine primary production and carbon uptake
(Journal article; Peer reviewed, 2023)Riverine transport of nutrients and carbon from inland waters to the coastal and finally the open ocean alters marine primary production (PP) and carbon (C) uptake regionally and globally. So far, this process has not been ... -
Tropical Atmospheric Response of Atlantic Niños to Changes in the Ocean Background State
(Journal article; Peer reviewed, 2023)Since the 1970s, Atlantic Niños during boreal summer have been linked to Pacific La Niñas the following winter. Earlier studies have explained the appearance of the Atlantic-Pacific teleconnection with changing Atlantic ... -
Linking Instantaneous and Climatological Perspectives on Eddy-Driven and Subtropical Jets
(Journal article; Peer reviewed, 2023)The distinction between eddy-driven and subtropical jets is conceptually important and well-founded based on different driving mechanisms and dominant types of variability. This climatological perspective may be augmented ... -
A flexible device to produce a gas stream with a precisely controlled water vapour mixing ratio and isotope composition based on microdrop dispensing technology
(Journal article; Peer reviewed, 2023)Here we describe a versatile device to produce a gas stream with a precisely controlled water vapour mixing ratio and stable water isotope composition based on microdrop dispensing technology. To produce a moist ... -
Flow Structure around a Multicopter Drone: A Computational Fluid Dynamics Analysis for Sensor Placement Considerations
(Journal article; Peer reviewed, 2023)This study presents a computational fluid dynamics (CFD) based approach to determine the optimal positioning for an atmospheric turbulence sensor on a rotary-wing uncrewed aerial vehicle (UAV) with X8 configuration. The ... -
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 ... -
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 ... -
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 ... -
