Arctic Ocean Response to Greenland Sea Wind Anomaliesin a Suite of Model Simulations
(Peer reviewed; Journal article, 2019-08-04)Plain Language Summary: The North Atlantic Current is an extension of the Gulf Stream, which brings warm Atlantic Water northward as the current flows through the Nordic Seas. Eventually, it enters the cold deep Arctic ... -
Atlantic water transformation along its poleward pathway across the Nordic Seas
(Peer reviewed; Journal article, 2018-08-23)The warm and salty Atlantic Water is substantially modified along its poleward transit across the Nordic Seas, where it reaches deeper isopycnals. In particular, the Lofoten Basin, exposed to intense air‐sea interactions, ... -
Consequences of future increased Arctic runoff on Arctic Ocean stratification, circulation, and sea ice cover
(Peer reviewed; Journal article, 2016-01-21)The Arctic Ocean has important freshwater sources including river runoff, low evaporation, and exchange with the Pacific Ocean. In the future, we expect even larger freshwater input as the global hydrological cycle ... -
Effects of sea-ice and biogeochemical processes and storms on under-ice water fCO2 during the winter-spring transition in the high Arctic Ocean: Implications for sea-air CO2 fluxes
(Peer reviewed; Journal article, 2017-07)We performed measurements of carbon dioxide fugacity (fCO2) in the surface water under Arctic sea ice from January to June 2015 during the Norwegian young sea ICE (N-ICE2015) expedition. Over this period, the ship drifted ... -
The Lofoten Basin Eddy: three years of evolution as observed by Seagliders
(Peer reviewed; Journal article, 2017-08)The Lofoten Basin in the Norwegian Sea is an area where the warm Atlantic Water is subject to the greatest heat losses anywhere in the Nordic Seas. A long-lived, deep, anticyclonic eddy is located in the central part of ... -
Mechanisms of Ocean Heat Anomalies in the Norwegian Sea
(Peer reviewed; Journal article, 2019-04)Ocean heat content in the Norwegian Sea exhibits pronounced variability on interannual to decadal time scales. These ocean heat anomalies are known to influence Arctic sea ice extent, marine ecosystems, and continental ... -
Observational validation of the diffusive convection flux laws in the Amundsen Basin, Arctic Ocean
(Peer reviewed; Journal article, 2015-12)The low levels of mechanically driven mixing in many regions of the Arctic Ocean make double diffusive convection virtually the only mechanism for moving heat up from the core of Atlantic Water towards the surface. In an ... -
One-dimensional evolution of the upper water column in the Atlantic sector of the Arctic Ocean in winter
(Peer reviewed; Journal article, 2017-03)A one-dimensional model is employed to reproduce the observed time evolution of hydrographic properties in the upper water column during winter, between 26 January and 11 March 2015, in a region north of Svalbard in the ... -
Projected changes in significant wave height toward the end of the 21st century: Northeast Atlantic
(Peer reviewed; Journal article, 2017-04)Wind field ensembles from six CMIP5 models force wave model time slices of the northeast Atlantic over the last three decades of the 20th and the 21st centuries. The future wave climate is investigated by considering the ... -
Temporal variability in surface water pCO2 in Adventfjorden (West Spitsbergen) with emphasis on physical and biogeochemical drivers
(Peer reviewed; Journal article, 2018-07)Seasonal and interannual variability in surface water partial pressure of CO2 (pCO2) and air‐sea CO2 fluxes from a West Spitsbergen fjord (IsA Station, Adventfjorden) are presented, and the associated driving forces are ... -
Turbulent heat and momentum fluxes in the upper ocean under Arctic sea ice
(Peer reviewed; Journal article, 2017-02)We report observations of heat and momentum fluxes measured in the ice-ocean boundary layer from four drift stations between January and June 2015, covering from the typical Arctic basin conditions in the Nansen Basin to ... -
Vertical fluxes of nitrate in the seasonal nitracline of the Atlantic sector of the Arctic Ocean
(Peer reviewed; Journal article, 2016-07)This study compiles colocated oceanic observations of high-resolution vertical profiles of nitrate concentration and turbulent microstructure around the Svalbard shelf slope, covering both the permanently ice-free Fram ... -
Water mass modification over the continental shelf north of Ronne Ice Shelf, Antarctica
(Journal article, 2003-08-13)We use new data from the southern Weddell Sea continental shelf to describe water mass conversion processes in a formation region for cold and dense precursors of Antarctic Bottom Water. The cruises took place in early ...
