  • Kulseng, Rasmus Kanstad (Master thesis, The University of Bergen, 2010-06-01)
    Six-hourly significant wave height (SWH) data covering the period September 1957 to August 2002 is obtained from the ERA-40 reanalysis. This data, generated by ECMWF's own configured global WAM model, stems from the first ...
  • Bergheim, Lillian (Master thesis, The University of Bergen, 2013-11-20)
    An analysis of three years of vertically pointing Micro Rain Radar (MRR) data from the measurement platform at the Geophysical Institute has been performed. The measurement period started at 13.04.2010 and ended at 12.04.2013. ...
  • Zygmuntowska, Marta; Khvorostovsky, Kirill (Journal article, The University of Bergen, 2014-06-11)
    Satellite altimetry has been used to derive information about sea ice thickness in the Arctic already for several decades. As part of the algorithms applied the shape of the radar signal is used to identify leads, the ...
  • Nassir, Sahbaldeen Abdulaziz (Master thesis, The University of Bergen, 2012-10-01)
    Data set including sea level, temperature, salinity, and current from Simple Ocean Data Assimilation (SODA) is used in this study to estimate the mean net annually and seasonally evaporation rates. Then wind data is used ...
  • Omar, Abdirahman M.; Johannessen, Truls; Kaltin, Staffan; Olsen, Are (Peer reviewed; Journal article, American Geophysical Union., 2003-12-26)
    We evaluate the change of surface water CO2 partial pressure ( pCO2 sw) in the Barents Sea (BS) between 1967 and 2000–2001. We use temperature (T) data collected during a survey in the BS in 1967 and a relationship between ...
  • Langehaug, Helene Reinertsen; Medhaug, Iselin; Eldevik, Tor; Otterå, Odd Helge (Journal article, American Meteorological Society, 2012)
    In the present study we investigate the decadal variability in the strength and shape of the Subpolar Gyre (SPG) in a 600-year pre-industrial simulation using the Bergen Climate Model. The atmospheric influence on the ...
  • Silyakova, Anna (Doctoral thesis, The University of Bergen, 2013-05-10)
    Human-induced CO2 emissions to the atmosphere cause climate change and ocean acidification. The strongest indicators of climate change and ocean acidification are expected to be found in the Arctic Ocean (AO). The AO ...
  • Zygmuntowska, Marta (Doctoral thesis, The University of Bergen, 2014-06-11)
    One of the most prominent features of global climate change is the reduction in Arctic sea ice thickness. The main tool to derive sea ice thickness on an Arctic wide scale is altimetry from satellites, yet current ...
  • Bjordal, Katrine Dale (Master thesis, The University of Bergen, 2006-05)
  • Byrkjedal, Øyvind (Doctoral thesis, The University of Bergen, 2006-06-08)
    The Arctic is a hot topic in Climate Research. A large number of signs of a warming Arctic Climate have been identified the latest years. This is of major concern in light of the increasing atmospheric content of greenhouse ...
  • Zilitinkevich, Sergej S.; Esau, Igor N.; Baklanov, A. (Journal article; Peer reviewed, European Geosciences Union/Copernicus, 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 ...
  • Divine, Dmitry; Korsnes, Reinert; Makshtas, Alexander; Godtliebsen, Fred; Svendsen, Harald (Journal article; Peer reviewed, American Geophysical Union, 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 ...
  • Drage, Magne A. (Doctoral thesis, The University of Bergen, 2005-04-15)
  • Ravnestad, Kristen Myklebust (Master thesis, The University of Bergen, 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 ...
  • Fer, Ilker; Paskyabi, Mostafa Bakhoday (Journal article, American Meteorological Society, 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, ...
  • Årthun, Marius; Eldevik, Tor; Smedsrud, Lars Henrik; Skagseth, Øystein (Preprint, The authors, 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 ...
  • 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. ...
  • Teigen, Sigurd Henrik; Nilsen, Frank; Gjevik, Bjørn (Peer reviewed; Journal article, American Geophysical Union, 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 ...
  • Hansen, Elisabeth (Master thesis, The University of Bergen, 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 ...
  • Sorteberg, Asgeir (Journal article, CICERO Senter for klimaforskning, 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 ...
