Hydrography, transport and mixing of the West Spitsbergen Current: the Svalbard Branch in summer 2015
Kolås, Eivind; Fer, Ilker (Peer reviewed; Journal article, 2018-12-21)Measurements of ocean currents, stratification and microstructure were made in August 2015, northwest of Svalbard, downstream of the Atlantic inflow in Fram Strait in the Arctic Ocean. Observations in three sections are ... -
Observations of Turbulence at a Near-Surface Temperature Front in the Arctic Ocean
Koenig, Zoé Charlotte; Fer, Ilker; Kolås, Eivind; Fossum, Trygve Olav; Norgren, Petter; Ludvigsen, Martin (Journal article; Peer reviewed, 2020)High-resolution ocean temperature, salinity, current, and turbulence data were collected at an Arctic thermohaline front in the Nansen Basin. The front was close to the sea ice edge and separated the cold and fresh surface ... -
Structure and Transport of Atlantic Water North of Svalbard From Observations in Summer and Fall 2018
Kolås, Eivind; Koenig, Zoé Charlotte; Fer, Ilker; Nilsen, Frank; Marnela, Marika (Journal article; Peer reviewed, 2020)The transport of warm Atlantic Waters north of Svalbard is one of the major heat and salt sources to the Arctic Ocean. The circulation pathways and the associated heat transport influence the variability in the Arctic sea ... -
The Svalbard branch of the West Spitsbergen Current: Hydrography, transport and mixing
Kolås, Eivind (Master thesis, 2017-08-01)Data from a 10 days shipboard survey in August 2015, northwest of Svalbard, are used to investigate the transport, structure and mixing of Atlantic water (AW) along the Svalbard branch and Yermak branch of the West Spitsbergen ... -
Tidally Forced Lee Waves Drive Turbulent Mixing Along the Arctic Ocean Margins
Fer, Ilker; Koenig, Zoé Charlotte; Kozlov, Igor E.; Ostrowski, Marek; Rippeth, Tom; Padman, L.; Bosse, Anthony; Kolås, Eivind (Journal article; Peer reviewed, 2020)In the Arctic Ocean, limited measurements indicate that the strongest mixing below the atmospherically forced surface mixed layer occurs where tidal currents are strong. However, mechanisms of energy conversion from tides ...
