    • Arctic Sea level Budget Assessment During the GRACE/Argo Time Period 

      Raj, Roshin Pappukutty; Andersen, Ole Baltazar; Johannessen, Johnny Andre; Benjamin, Gutknech; Chatterjee, Sourav; Rose, Stine; Bonaduce, Antonio; Horwath, Martin; Ranndal, Heidi; Richter, Kristin; Palanisamy, Hindumathi; Ludwigsen, Carsten; Bertino, Laurent; Nilsen, Jan Even Øie; Knudsen, Per; Hogg, Anna E.; Cazenave, Anny; Benveniste, Jérôme (Journal article; Peer reviewed, 2020)
      Sea level change is an important indicator of climate change. Our study focuses on the sea level budget assessment of the Arctic Ocean using: (1) the newly reprocessed satellite altimeter data with major changes in the ...

    • The Atlantic Water flow along the Vøring Plateau: Detecting frontal structures in oceanic station time series 

      Nilsen, Jan Even Øie; Nilsen, Frank (Journal article, 2007-01-13)
      The topographic steering of the baroclinic western branch of the Norwegian Atlantic Current (NwAC) determines the extent of Atlantic Water and location of the Arctic Front in the Nordic Seas. In this paper the geographical ...

    • A brief history of climate – the northern seas from the Last Glacial Maximum to global warming 

      Eldevik, Tor; Risebrobakken, Bjørg; Bjune, Anne Elisabeth; Andersson, Carin; Birks, Harry John Betteley; Dokken, Trond Martin; Drange, Helge; Glessmer, Mirjam Sophia; Li, Camille; Nilsen, Jan Even Øie; Otterå, Odd Helge; Richter, Kristin; Skagseth, Øystein (Peer reviewed; Journal article, 2014-12)
      The understanding of climate and climate change is fundamentally concerned with two things: a well-defined and sufficiently complete climate record to be explained, for example of observed temperature, and a relevant ...

    • The European Climate Research Alliance (ECRA): Collaboration from bottom-up 

      Hoke, Winfried; Swierczynski, Tina; Braesicke, Peter; Lochte, Karin; Shaffrey, Len; Drews, Martin; Gregow, Hilppa; Ludwig, Ralf; Nilsen, Jan Even Øie; Palazzi, Elisa; Sannino, Gianmaria; Smedsrud, Lars H. (Peer reviewed; Journal article, 2019-01-17)
      The European Climate Research Alliance (ECRA) is an association of leading European research institutions in the field of climate research (http://www.ecra-climate.eu/, last access: 6 December 2018). ECRA is a bottom-up ...

    • Large-Scale Atmospheric Circulation Variability and its Impacts on the Nordic Seas Ocean Climate - a Review. In: The Nordic Seas: An Integrated Perspective 

      Furevik, Tore; Nilsen, Jan Even Øie (Geophysical Monograph Series;158, Chapter, 2005)
      The large-scale atmospheric circulation and its impacts on the Nordic Seas ocean climate are reviewed. The dominant factors for the atmospheric variability are the Icelandic low and the Azores high, determining the strength ...

    • North Atlantic ocean circulation and decadal sea level change during the Altimetry era 

      Chafik, Leon Martin; Nilsen, Jan Even Øie; Dangendorf, Sönke; Reverdin, Gilles; Frederikse, Thomas (Peer reviewed; Journal article, 2019-01-31)
      Regional sea-level rise is characterized by decadal acceleration and deceleration periods that typically stem from oceanic climate variability. Here, we investigate decadal sea-level trends during the altimetry era and pin ...

    • On the recent time history and forcing of the inflow of Atlantic Water to the Arctic Mediterranean 

      Nilsen, Jan Even Øie; Hátún, Hjalmar; Sandø, Anne Britt; Bethke, Ingo; Laurantin, Olivier; Gao, Yongqi; Drange, Helge; Furevik, Tore (Extended Abstract for The ACIA International Scientific Symposium on Climate Change in the Arctic, Conference lecture, 2004)

    • The relationship between the eddy-driven jet stream and northern European sea level variability 

      Mangini, Fabio; Chafik, Léon; Madonna, Erica; Li, Camille; Bertino, Laurent; Nilsen, Jan Even Øie (Journal article; Peer reviewed, 2021)
      Wintertime sea level variability over the northern European continental shelf is largely wind-driven. Using daily gridded sea level anomaly from altimetry, we examine both the spatial and the temporal relationship between ...

    • Simulated North Atlantic-Nordic Seas water mass exchanges in an isopycnic coordinate OGCM 

      Nilsen, Jan Even Øie; Gao, Yongqi; Drange, Helge; Furevik, Tore; Bentsen, Mats (Journal article, 2003-05-29)
      The variability in the volume exchanges between the North Atlantic and the Nordic Seas during the last 50 years is investigated using a synoptic forced, global version of the Miami Isopycnic Coordinate Ocean Model (MICOM). ...

    • Variability at Ocean Weather Station M in the Norwegian Sea 

      Nilsen, Jan Even Øie (ICES Marine Science Symposia; 219, Chapter, 2003)
      Time series of temperature and salinity from Ocean Weather Station M are analysed for periodic cycles of interannual to decadal scale. Time evolutions of the spectra show various spectral peaks at all depths, but none of ...

    • Variations of Mixed Layer Depth and Water Properties in the Norwegian Sea for the period 1949-1999 

      Nilsen, Jan Even Øie; Falck, Eva (Peer reviewed; Journal article, 2006-06-08)
      The mixed layer of the ocean and the processes therein affect the ocean’s biological production, the exchanges with the atmosphere, and the water modification processes important in a climate change per- spective. To provide ...
