  1. Blank to start

  2. Low Frequency Variability on Georges Bank R. Limeburner, K. Brink and R. Beardsley Woods Hole Oceanographic Institution Woods Hole, MA

  3. Low Frequency Current Moored current meter data Fluctuations < 33 hr removed Low frequency variance is dominated by 65 and 95 hr fluctuations in winter Spatial scales < 10 km

  4. Moorings 1995-99

  5. South Flank ADCP U lp

  6. South Flank ADCP December 98

  7. South Flank 20m Nov98-Mar99

  8. Nov 98 – Mar 99

  9. SF April-August 1999

  10. SF Bandpass 82-108 hr U winter

  11. Principal Axis

  12. Band Pass Displacements

  13. November 98 – March 99

  14. Coherence Phase

  15. Phase Speed

  16. Conclusions GB low frequency variability at 65 and 95 hrs Strongest in winter on South Flank Barotropic Fluctuations propagate clockwise around GB Continental shelf waves? Forcing?
