1 SVINØY SECTION A full-scale ocean climate laboratory in the Norwegian Atlantic Current

2 Warming of the Atlantic Inflow to the Norwegian Sea toward Arctic; 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 EOF-mode 2: 13.4 % of Variance Hakkinen & Rhines, 2004 Sea Surface High (SSH) from TOPEX/Poseidon altimeter. 1/3 deg resolution 1-year mv-filter

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 appears to be determined by the dynamic processes in the North Atlantic

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