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 ... -
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 ... -
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 ... -
Recent applications and potential of near-term (interannual to decadal) climate predictions
(Journal article; Peer reviewed, 2023)Following efforts from leading centres for climate forecasting, sustained routine operational near-term climate predictions (NTCP) are now produced that bridge the gap between seasonal forecasts and climate change projections ... -
Vertical Convergence of Turbulent and Double-Diffusive Heat Flux Drives Warming and Erosion of Antarctic Winter Water in Summer
(Journal article; Peer reviewed, 2023)The seasonal warming of Antarctic Winter Water (WW) is a key process that occurs along the path of deep water transformation to intermediate waters. These intermediate waters then enter the upper branch of the circumpolar ... -
Atlantic Water Boundary Current Along the Southern Yermak Plateau, Arctic Ocean
(Journal article; Peer reviewed, 2023)The major ocean current that carries heat into the Arctic Ocean splits into three main branches of Atlantic Water (AW) and recirculations when it encounters the Yermak Plateau (YP) located north of Svalbard. While the ... -
The Earth system model CLIMBER-X v1.0 - Part 2: The global carbon cycle
(Journal article; Peer reviewed, 2023)The carbon cycle component of the newly developed Earth system model of intermediate complexity CLIMBER-X is presented. The model represents the cycling of carbon through the atmosphere, vegetation, soils, seawater and ... -
Self-nested large-eddy simulations in PALM model system v21.10 for offshore wind prediction under different atmospheric stability conditions
(Journal article; Peer reviewed, 2023)Large-eddy simulation (LES) resolves large-scale turbulence directly and parametrizes small-scale turbulence. Resolving micro-scale turbulence, e.g., in wind turbine wakes, requires both a sufficiently small grid spacing ... -
Key physical processes and their model representation for projecting climate impacts on subarctic Atlantic net primary production: A synthesis
(Journal article; Peer reviewed, 2023)Oceanic net primary production forms the foundation of marine ecosystems. Understanding the impact of climate change on primary production is therefore critical and we rely on Earth System Models to project future changes. ... -
Pore-scale studies of CO2-hydrate sealing mechanisms - effect of salinity

The Impact of Cold-Air Outbreaks and Oceanic Lateral Fluxes on Dense-Water Formation in the Greenland Sea from a 10-Year Moored Record (1999–2009)
(Journal article; Peer reviewed, 2023)The Greenland Sea produces a significant portion of the dense water from the Nordic seas that supplies the lower limb of the Atlantic meridional overturning circulation. Here, we use a continuous 10-yr hydrographic record ... -
Global Surface Ocean Acidification Indicators From 1750 to 2100
(Journal article; Peer reviewed, 2023)Accurately predicting future ocean acidification (OA) conditions is crucial for advancing OA research at regional and global scales, and guiding society's mitigation and adaptation efforts. This study presents a new ... -
Warm air intrusions reaching the MOSAiC expedition in April 2020- The YOPP targeted observing period (TOP)
(Journal article; Peer reviewed, 2023)In the spring period of the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition, an initiative was in place to increase the radiosounding frequency during warm air intrusions in the ... -
Ocean Breath: Origin, Transport and Fate of Anthropogenic Carbon and Oxygen in the Ocean
(Doctoral thesis, 2023-08-25)Menneskeskapte klimaendringer endrer måten atmosfæren og havet utveksler energi og egenskaper på ved å redusere havventilasjonen. Endringer i ventilasjonen antas å være en viktig tilbakekoblingsmekanisme i klimasystemet ... -
Knowledge Gaps and Impact of Future Satellite Missions to Facilitate Monitoring of Changes in the Arctic Ocean
(Journal article; Peer reviewed, 2023)Polar-orbiting satellite observations are of fundamental importance to explore the main scientific challenges in the Arctic Ocean, as they provide information on bio-geo-physical variables with a denser spatial and temporal ... -
Can a dual pulsed lidar system measure the lateral coherence of turbulence?
