Presentation Transcript

  1. SVINØY SECTIONA full-scale ocean climate laboratory in the Norwegian Atlantic Current

  2. Warming of the Atlantic Inflow to the Norwegian Sea toward Arctic; 1995-2005 by Kjell Arild Orvik and Øystein Skagseth Geophysical Inst., University of Bergen, and Marine Research Inst., Bergen • Outline • - What causes the extreme warming • Connect it to dynamical processes in the North Atlantic • Strength of the Sub-Polar Gyre and interaction of water masses • - Moored temp/current measurements the in Svinøy Section • - Sea Surface High (SSH) observations from satellite altimeter • - Empirical Orthogonal functions (EOF) methodology

  3. Major Pathways of Atlantic Water and extension of Atlantic Water in North Atlantic & Norwegin Sea, from SVP-drifters Orvik & Niiler, GRL 2002

  4. Vertically integrated transport of Atlantic Inflow Orvik, Skagseth & Mork, DSR 2001 Orvik & Skagseth, CSR 2003

  5. Temperature, Velocity & Heat-flux variations in the core of the AI Orvik & Skagseth, GRL 2005

  6. Timeseries of vT variations Connected to variarions in V and T Orvik & Skagseth,GRL 2005

  7. Hakkinen & Rhines, 2004 Sea Surface High (SSH) from TOPEX/Poseidon altimeter. 1/3 deg resolution 1-year mv-filter EOF-mode 2: 13.4 % of Variance

  8. Time series of v and T in Svinøy Section updated to 2006 have been removed from the presentation, contact the author if you need further details

  9. CONCLUSION The warming of the Atlantic Inflow to the Norwegian Sea toward the Arctic Ocean 1995-2005 appears to be determined by the dynamic processes in the North Atlantic

  10. Hakkinen & Rhines, 2004 Sea Surface High (SSH) from TOPEX/Poseidon altimeter. 1/3 deg resolution 1-year mv-filter EOF-mode 1: 43.9 % of Variance
