      Håvik, Lisbeth; Almansi, Mattia; Våge, Kjetil; Haine, Thomas W.N. (Peer reviewed; Journal article, 2019)
      Dense water masses transported southward along the east coast of Greenland in the East Greenland Current (EGC) form the largest contribution to the Denmark Strait Overflow. When exiting Denmark Strait these dense water ...
    • Atmospheric boundary layers in storms: advanced theory and modelling applications 

      Zilitinkevich, Sergej S.; Esau, Igor N.; Baklanov, A. (Peer reviewed; Journal article, 2005-03-29)
      Turbulent planetary boundary layers (PBLs) control the exchange processes between the atmosphere and the ocean/land. The key problems of PBL physics are to determine the PBL height, the momentum, energy and matter fluxes ...
    • Atmospheric Circulation Response to Short-Term Arctic Warming in an Idealized Model 

      Hell, Momme; Schneider, Tapio; Li, Camille (Journal article; Peer reviewed, 2020)
      Recent Arctic sea ice loss in fall has been posited to drive midlatitude circulation changes into winter and even spring. Past work has shown that sea ice loss can indeed trigger a weakening of the stratospheric polar ...
    • Atmospheric response to removal of Southern Hemisphere sea ice - a model study 

      Ravnestad, Kristen Myklebust (Master thesis, 2010-06-01)
      The atmospheric response to the removal of Southern Hemisphere sea ice is studied using the ICTP AGCM (SPEEDY) model with an uncoupled ocean. The results show large increases in surface heat flux from the ocean to the ...
    • Atmospheric response to zonally averaged sea surface temperatures in the North Atlantic - a model study 

      Fagerli, Stig-Arild (Master thesis, 2008-05-29)
      A less dynamically active ocean will most likely lead to a more zonal sea surface temperature (SST) distribution. In order to identify if, and how such an effect affects the atmospheric variability, idealized experiments ...
    • Atmospheric-driven state transfer of shore-fast ice in the northeastern Kara Sea 

      Divine, Dmitry; Korsnes, Reinert; Makshtas, Alexander; Godtliebsen, Fred; Svendsen, Harald (Journal article, 2005-09-21)
      Frequencies of observed occurrences of shore-fast ice in the northeastern Kara Sea for each month during 1953–1990 reveal a multimodality of shore-fast ice extent in late winter and spring. The fast ice extent exhibits ...

      Paskyabi, Mostafa Bakhoday; Reuder, Joachim; Flügge, Martin (Peer reviewed; Journal article, 2016-12)
      We quantify the percentage of sea surface covered by whitecaps from images taken by a non-stationary camera mounted on a moored buoy using an Adaptive Thresholding Segmentation (ATS) method and an Iterative Between Class ...
    • Autonomous Ocean Turbulence Measurements Using Shear Probes on a Moored Instrument 

      Fer, Ilker; Paskyabi, Mostafa Bakhoday (Peer reviewed; Journal article, 2014-02)
      An internally recording, autonomous instrument has been tested for measurements of ocean turbulence from a mooring line. Measurements were made at a single level in the water column, but for an extended period of time, at ...
    • Avvik mellom estimert og faktisk energiproduksjon for småkraftverk 

      Lie, Sindre Blomvågnes (Master thesis, 2016-06-01)
      I denne oppgaven har jeg sett på årsakene til avviket mellom estimert og faktisk energiproduksjon for tre av kraftverkene som Småkraft AS sammen med grunneier har hatt i drift i 8-9 år. Kraftverkene jeg har sett på er Ytre ...
    • Barents Sea ice cover reflects Atlantic inflow 

      Årthun, Marius; Eldevik, Tor; Smedsrud, Lars Henrik; Skagseth, Øystein (2011)
      The recent Arctic winter sea-ice retreat is most pronounced in the Barents Sea. Using available observations of the Atlantic inflow to the Barents Sea and results from a regional ice-ocean model we assess the role of ...
    • Baroclinic Instability in the West Spitsbergen Current 

      Teigen, Sigurd Henrik; Nilsen, Frank; Skogseth, Ragnheid; Gjevik, Bjørn; Beszczynska-Möller, Agnieszka (Peer reviewed; Journal article, 2011-07-15)
      Baroclinic instability in the West Spitsbergen Current is investigated, based on data from an array of current meter moorings along 78.83oN, across the deeper (1000-2400 m) section of the continental slope west of Svalbard. ...
    • Barotropic instability in the West Spitsbergen Current 

      Teigen, Sigurd Henrik; Nilsen, Frank; Gjevik, Bjørn (Peer reviewed; Journal article, 2010-07-24)
      Barotropic instability in the shoreward branch of the West Spitsbergen Current is investigated on the basis of data from an array of current meter moorings along 78.83°N, across the upper continental slope and shelf break ...
    • Basin Interactions and predictability

    • Batterilading i hybride fremdriftssystemer ved hjelp av tapsenergi fra forbrenningsmotoren 

      Nygård, Erlend (Master thesis, 2017-06-23)
      In a time when emission standards are getting stricter, the search for more environmentally friendly propulsion is more relevant than ever. Hybridization and electric propulsion has, thus, become more common in some sectors, ...
    • Benguela Niños: Observations and Modelling 

      Hansen, Elisabeth (Master thesis, 2004)
      A numerical ocean model for the South Atlantic was used to study the 1995 Benguela Niño in order to learn about the underlying forcing mechanisms of the phenomenon. By comparing observations and model output, it was found ...

    • Bruk og misbruk av klimaframskrivninger 

      Sorteberg, Asgeir (Journal article, 2009)
      Forskere er avhengig av pålitelige klimaframskrivninger for å kunne si hvilke konsekvenser klimaforandringer får for mennesker og samfunn i framtiden. Men hva kan klimaframskrivninger brukes til og hvordan bør de brukes?
