Adaptive Sampling of Surface Fronts in the Arctic Using an Autonomous Underwater Vehicle
Fossum, Trygve Olav; Norgren, Petter; Fer, Ilker; Nilsen, Frank; Koenig, Zoe Charlotte; Ludvigsen, Martin (Peer reviewed; Journal article, 2021)Fronts between Arctic- and Atlantic-origin waters are characterized by strong lateral gradients in temperature and salinity. Ocean processes associated with fronts are complex with considerable space and time variability. ... -
Mixing in the stratified interface of the Faroe Bank Channel overflow: the role of transverse circulation and internal waves
Seim, Knut Sponheim; Fer, Ilker (Journal article; Peer reviewed, 2011)The overflow of cold water across the Faroe Bank Channel sill is a significant volume flux of dense water to the North Atlantic Ocean. Using observations of hydrography, current and microstructure from a 1 week cruise and ... -
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 (Peer reviewed; Journal article, 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 ... -
Still Arctic? — The changing Barents Sea
Gerland, Sebastian; Ingvaldsen, Randi Brunvær; Reigstad, Marit; Sundfjord, Arild; Bogstad, Bjarte; Chierici, Melissa; Hop, Haakon; Renaud, Paul Eric; Smedsrud, Lars Henrik; Stige, Leif Christian; Årthun, Marius; Berge, Jørgen; Bluhm, Bodil Annikki Ulla Barbro; Borgå, Katrine; Bratbak, Gunnar; Divine, Dmitry V; Eldevik, Tor; Eriksen, Elena; Fer, Ilker; Fransson, Agneta; Gradinger, Rolf Rudolf; Granskog, Mats A.; Haug, Tore; Husum, Katrine; Johnsen, Geir; Jonassen, Marius Opsanger; Jørgensen, Lis Lindal; Kristiansen, Svein; Larsen, Aud; Lien, Vidar Surén; Lind, Sigrid; Lindstrøm, Ulf Ove; Mauritzen, Cecilie; Melsom, Arne; Mernild, Sebastian H.; Müller, Malte; Nilsen, Frank; Primicerio, Raul; Søreide, Janne; van der Meeren, Gro Ingleid; Wassmann, Paul (Peer reviewed; Journal article, 2023)The Barents Sea is one of the Polar regions where current climate and ecosystem change is most pronounced. Here we review the current state of knowledge of the physical, chemical and biological systems in the Barents Sea. ... -
Stratified flow over complex topography: A model study of the bottom drag and associated mixing
Seim, Knut Sponheim; Fer, Ilker; Avlesen, Helge (Journal article; Peer reviewed, 2012)The flow of stratified fluid over complex topography may lead to a significant drag on the fluid, exerted by the bottom obstacles. Using a 2-m resolution, three-dimensional, non hydrostatic numerical ocean model, the drag ... -
Technical note: Turbulence measurements from a light autonomous underwater vehicle
Kolås, Eivind Hugaas; Mo-Bjørkelund, Tore; Fer, Ilker (Peer reviewed; Journal article, 2022)A turbulence instrument was installed on a light autonomous underwater vehicle (AUV) and deployed in the Barents Sea in February 2021. We present the data quality and discuss limitations when measuring turbulence from the ...
