Observing Antarctic Bottom Water in the Southern Ocean
(Journal article; Peer reviewed, 2023)Dense, cold waters formed on Antarctic continental shelves descend along the Antarctic continental margin, where they mix with other Southern Ocean waters to form Antarctic Bottom Water (AABW). AABW then spreads into the ... -
Supermodeling Improving Predictions with an Ensemble of Interacting Models
(Journal article; Peer reviewed, 2023)The modeling of weather and climate has been a success story. The skill of forecasts continues to improve and model biases continue to decrease. Combining the output of multiple models has further improved forecast skill ... -
Interdecadal Changes in the Linkage Between North Pacific Oscillation During May and Northeast China Precipitation During Mid-Summer: The Influence of North Atlantic Oscillation
(Journal article; Peer reviewed, 2023)Many previous studies have documented the relationship between the North Pacific Oscillation (NPO) and the weather/climate of upstream and downstream regions. However, the stability of NPO precursor signals of East Asian ... -
Thin and transient meltwater layers and false bottoms in the Arctic sea ice pack-Recent insights on these historically overlooked features
(Journal article; Peer reviewed, 2023)The rapid melt of snow and sea ice during the Arctic summer provides a significant source of low-salinity meltwater to the surface ocean on the local scale. The accumulation of this meltwater on, under, and around sea ice ... -
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 ... -
Mechanisms of offshore solid and liquid freshwater flux from the East Greenland Current
(Journal article; Peer reviewed, 2024)The mechanisms that control the export of freshwater from the East Greenland Current, in both liquid and solid form, are explored using an idealized numerical model and scaling theory. A regional, coupled ocean–sea ice ... -
Present and future drivers of Arctic sea ice variability
(Doctoral thesis, 2024-03-07)Havisdekket i Arktis har blitt gradvis redusert de siste tiårene. Isdekket varierer likevel betydelig fra år til år, og fra tiår til tiår på grunn av naturlige (interne) variasjoner i klimasystemet. Slike interne variasjoner ... -
Forced and internal components of observed Arctic sea-ice changes
(Journal article; Peer reviewed, 2023)The Arctic sea-ice cover is strongly influenced by internal variability on decadal timescales, affecting both short-term trends and the timing of the first ice-free summer. Several mechanisms of variability have been ... -
From winter to late summer in the northwestern Barents Sea shelf: Impacts of seasonal progression of sea ice and upper ocean on nutrient and phytoplankton dynamics
(Journal article; Peer reviewed, 2024)Strong seasonality is a key feature of high-latitude systems like the Barents Sea. While the interannual variability and long-term changes of the Barents Sea are well-documented, the seasonal progression of the physical ... -
Waste heat recovery for lunar applications of a solid oxide electrolyser
(Master thesis, 2023-12-20)In an effort to make space exploration more sustainable the space industry looks to In-Situ Resource Utilisation (ISRU) as a possible way to lower the cost. With confirmed findings of water ice on the south pole of Earth’s ... -
Impacts of the extratropical North Pacific on boreal summer Arctic circulation
(Journal article; Peer reviewed, 2023)A distinct characteristic of the Arctic summer atmospheric circulation is the anomalous anticyclonic circulation centered over the Arctic Ocean associated with significant Arctic warming. Previous studies have related the ... -
Diffusive and advective cross-frontal fluxes of inorganic nutrients and dissolved inorganic carbon in the Barents Sea in autumn
(Journal article; Peer reviewed, 2023)The Atlantic Water, entering the Arctic through the Barents Sea and Fram Strait, is the main source of nutrients in the Arctic Ocean. The Barents Sea is divided by the Polar Front into an Atlantic-dominated domain in the ... -
Arctic Warming and Eurasian Cooling: Weakening and Reemergence
(Journal article; Peer reviewed, 2023)The observed Eurasian winter surface cooling from the 1990s to the early 2010s, which is contrary to global warming, has been extensively studied. Previous studies revealed that the surface cooling trend has significantly ... -
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 ... -
