2 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Topography and Circulation

3 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank 16 February 1999 crossover

4 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank 5 March 1997 crossover

5 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Mooring records

6 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Drifters

7 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Important Factors Freshwater pulses from the Gulf of St. Lawrence Along-shelf flow in the shelf/slope front Instability of the SSW front around Browns Bank Synoptic wind events Warm-core rings

8 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Williams et al. 2001

9 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Numerical modeling

10 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Bathymetry

11 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Abrupt changes: 1.5 C

12 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Kuroshio

13 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Lab Experiment

14 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Onset of Flow Separation

15 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Particle Image Velocimetry

16 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Importance of Bottom Drag Advective time scale Scotian Shelf, Strong tidal dissipation Laboratory

17 Sheremet November 18-20, 2003U.S. GLOBEC Georges Bank Conclusions Numerical experiments suggest that the system is close to a bimodal state Baroclinicity and friction relax potential vorticity constraint and allow the crossover Inertia promotes the crossovers and along with baroclinicity affects the position of flow separation Tidally modulated bottom drag, especially during winter unstratified conditions
