  • Jansen, Teunis; Kristensen, Kasper; Payne, Mark; Edwards, Martin; Schrum, Corinna; Pitois, Sophie (Peer reviewed; Journal article, Public Library of Science, 2012-06-21)
    We present a unique view of mackerel (Scomber scombrus) in the North Sea based on a new time series of larvae caught by the Continuous Plankton Recorder (CPR) survey from 1948-2005, covering the period both before and ...
  • Tjiputra, Jerry; Olsen, Are; Bopp, Laurent; Lenton, Andrew; Pfeil, Benjamin; Roy, Tilla; Segschneider, Joachim; Totterdell, Ian; Heinze, Christoph (Journal article, Co-Action PublishingThe International Meteorological Institute in Stockholm, 2014-05-19)
    We estimate regional long-term surface ocean pCO2 growth rates using all available underway and bottled biogeochemistry data collected over the past four decades. These observed regional trends are compared with those ...
  • Onarheim, Ingrid Husøy; Smedsrud, Lars Henrik; Ingvaldsen, Randi; Nilsen, Frank (Journal article, International Meteorological Institute, Stockholm University, 2014-06-05)
    Sea ice loss in the Arctic Ocean has up to now been strongest during summer. In contrast, the sea ice concentration north of Svalbard has experienced a larger decline during winter since 1979. The trend in winter ice area ...
  • Keiderling, Stefan (Master thesis, The University of Bergen, 2013-06-03)
    The goal of the presented thesis is to investigate the formation of low level jets at the sea ice edge. Differential heating creates very sharp fronts at the ice edge. A transversal circulation, initiated by altered pressure ...
  • Henden, Amelie (Master thesis, The University of Bergen, 2011-06-01)
    I dette arbeidet er globalstrålingsdata fra Ekofisk, Arktis og fastlandsstasjoner i Norge og Sverige studert. Stasjonene ligger mellom 56°N og 75°N, og all data er hentet fra perioden 2005 til og med 2010. Målinger i Arktis ...
  • Sætre, Ottar (Master thesis, The University of Bergen, 2006)
  • Kvæstad, Elise (Master thesis, The University of Bergen, 2013-12-20)
    Self organizing maps (SOMs) have been used to estimate seawater fugacity of CO2 (fCO2) distribution in the Nordic Seas and the northern North Atlantic Ocean for 2005-2007. Four maps were produced for each region using ...
  • Svendsen, Lea; Hetzinger, Steffen; Keenlyside, Noel; Gao, Yongqi (Journal article, WileyAmerican Geophysical Union, 2014-02-28)
    Atlantic multidecadal variability (AMV) is known to impact climate globally, and knowledge about the persistence of AMV is important for understanding past and future climate variability, as well as modeling and assessing ...
  • Aarnes, Ole Johan; Abdalla, Saleh; Bidlot, Jean-Raymond; Breivik, Øyvind (Journal article, American Meteorological Society, 2015-01-15)
    Trends in marine wind speed and significant wave height are investigated using the global reanalysis ERA-Interim over the period 1979–2012, based on monthly-mean and monthly-maximum data. Besides the traditional reanalysis, ...
  • Dong, Cai (Master thesis, The University of Bergen, 2004)
    NyainQen TangLha Glacier plays an important role in the Tibetan plateau’s climate system. Because of high altitude, steeply sloping terrain and difficult access, regular, systematic surveys of glacial variation are almost ...
  • Hagen, Linda (Master thesis, The Universitetet i Bergen, 2011-06-01)
    This article presents a comparison of global radiation data at different sites at the Scandinavian Peninsula. It makes use of ground truth, modelled and satellite derived surface global radiation data. First, a quality ...
  • Østerhus, Svein; Turrell, William R.; Jónsson, Steingrímur; Hansen, Bogi (Journal article, American Geophysical Union, 2005-04-07)
    The flow of warm and saline Atlantic water towards the Arctic crosses the Greenland-Scotland Ridge in three current branches. Since the mid 1990's, extensive monitoring with quasi-permanent moorings and regular CTD cruises ...
  • Nielsen, Kristian Pagh (Master thesis, The University of Bergen, 2001)
  • Barthel, Knut; Gade, Herman G.; Sandal, Cathrine K. (Journal article, Pergamon, 2004-06-29)
    A three-dimensional baroclinic numerical model is used to quantify the components of the mechanical energy budget for a semi-enclosed sea, the North Sea. As anticipated, tidal energy is the largest supplier of mechanical ...
  • Myksvoll, Mari Skuggedal (Master thesis, The University of Bergen, 2008-05-30)
    The fjord system of Sørfolda and Nordfolda situated in northern Norway is used in a model study. Particularly to explore the mechanisms causing separation and mixing of eggs from Arcto-Norwegian Cod (ANC) and Norwegian Coastal ...
  • Medhaug, Iselin; Langehaug, Helene Reinertsen; Eldevik, Tor; Furevik, Tore; Bentsen, Mats (Peer reviewed; Journal article, Springer Verlag, 2011-06-25)
    Variability in the Atlantic Meridional Overturning Circulation (AMOC) has been analysed using a 600-year pre-industrial control simulation with the Bergen Climate Model. The typical AMOC variability has amplitudes of 1 ...
  • Godø, Olav Rune; Samuelsen, Annette; Macaulay, Gavin J.; Patel, Ruben; Hjøllo, Solfrid Sætre; Horne, John; Kaartvedt, Stein; Johannessen, Johnny A. (Peer reviewed; Journal article, Public Library of Science, 2012-01-17)
    Mesoscale eddies stimulate biological production in the ocean, but knowledge of energy transfers to higher trophic levels within eddies remains fragmented and not quantified. Increasing the knowledge base is constrained ...
  • Backeberg, Bjørn C. (Master thesis, The University of Bergen, 2006-06)
    Towards understanding the dynamics and eddy evolving processes in the greater Agulhas Current system, a Hybrid Coordinate Ocean Model (HYCOM) system has been set up to simulation the ocean circulation around Southern ...
  • Haugan, Peter Mosby; Joos, Fortunat (Journal article; Peer reviewed, American Geophysical Union, 2004-09-18)
    Different metrics to assess mitigation of global warming by carbon capture and storage are discussed. The climatic impact of capturing 30% of the anthropogenic carbon emission and its storage in the ocean or in ...
  • Meland, Marius Yddal; Jansen, Eystein; Elderfield, Henry; Dokken, Trond Martin; Olsen, Are; Bellerby, Richard G. J. (Journal article; Peer reviewed, American Geophysical Union, 2006-06-15)
    In core top samples in the Nordic Seas, Mg/Ca ratios of N. pachyderma (sin.) are generally consistent with previous high-latitude calibration data but do not reflect the modern calcification temperature gradient from 2ºC ...
