Animations: Circulation modeling for the Georges Bank and Gulf of Maine region has been developed by the Dartmouth College Numerical Methods Laboratory as a part of the GLOBEC George's Bank program. These efforts have produced some very thought provoking tools and simulations that have direct application to our understanding of fisheries in the region.

Here are two sample files converted to animated gif format for viewing directly in your web browser.
1. Closed Area Reseeding, gif (438k)
2. Particle drift from Hudson Canyon scallop growout area, gif (~2MB), thanks to John Quinlan

If you like these animated gif simulations, the more functional original flc format animations can be obtained by first downloading the fli/flc player (~150k zipped) from Rich Signell's website - http://crusty.er.usgs.gov/flc.html, or elsewhere and installing it (best in it's own directory). Then download the last file in movie column (2.6MB) from the
3. Craig Lewis website or go to
4. http://www-nml.dartmouth.edu/Publications/internal_reports/NML-00-2/

Best to put the fli or flc files in the same directory as the player for ease of access at least when running the player within the Windows OS. Be forewarned, this is only a test, had this been a real simulation...

05/18/01 The first four animations below are from Charles Miller and Craig Lewis, developed for the GLOBEC program effort, displaying sources and drift of various life stages of Calanus, a major food source for larval groundfish and whales. These animations indicate expected drift over time from various start points. Remember these require the flc/fli viewer as a plugin (Quicktime will display the flc format within html but is not fully functional. To restart a sequence using Quicktime, double click on the image space after it stops). Or download both AAwin viewer and the flc files into a separate folder.

6.  Wilkinson Basin (flc, 461k)   7.  Jordan Basin (flc, 473k)   8.  Georges Basin (flc, 424k)   9.  Scotian Shelf (flc, 833k) The remainder are animations i've developed. 10. AVHRR image sequence from May 1994, gif ~140k 11. Zooming in on the Great South Channel, 1st Flash loop ~460k, 12. Full screen Great South Channel Zoom, Flash 13. Scallop settlement Great South Channel and Georges Bank, gif (800k) 14. Larger scale Great South Channel / Georges Bank , gif (305k) 15. Shelfwide settlement, gif (168k)

Legend for 13, 14, and 15: small black dots = no scallop, dark green = 1 to 109, light green = 110 to 250, yellow = 251 to 500, red = 501 to 19,520 scallop

Scallop survey data for scallop <70mm, provided by NEFSC for 1982-1996.15 minutes tow time.
Note that several areas in these last three animations exhibit repeated recolonization over time.
These areas have been fished intensively for over 50 years.
