The figures on the following pages show the climatological circulation features of Stellwagen Bank. They were made using the DROG3D program, release 95.1 by Brian Blanton at the OPNML at the University of North Carolina at Chapel Hill. Various conditions were set using a matlab interface, including the number of tidal cycles to run, the reporting interval, the drogue depth, whether to fix this depth or not, and the initial coordinates of each drogue. For each run, the total number of tidal cycles was set at 60 and positions were reported every 24 hours. The drogues were released at positions surrounding the Bank that were likely to have an influence on it and an additional two to three were released on the Bank itself. The figures are sorted according to the bimonthly climatology used, with each of the climatologies listed below. For each of the six climatologies, runs were completed at 1m, 5m, 10m, 20m, 30m, and 50m. For every depth, the program was run with both passive drogues, which were allowed to move horizontally and vertically, and fixed drogues, which remained at the same depth for the entire period. Since the figures were shrunk in order to fit them all on one page, a larger gif image may be obtained by clicking on the image of interest. If you click on the top left-hand corner of the image, you will get a higher quality postscript image.
The first set of links listed below leads to figures made by using bimonthly climatologies located in the 'Dartmouth circulation models for the Gulf of Maine and Georges Bank' data archives. A published reference to this data may be found in Continental Shelf Research. For these figures, the same set of initial launch points was used for both the passive and fixed runs at each depth, but does not carry over from season to season.

The second set of links contains figures made with new, updated meshes that are more detailed in the Stellwagen Bank area and are more accurate than the previous figures located in the data archives. An added feature of these figures is that the same set of initial drogue coordinates was used for every image containing drogues released at 1m, including all six seasons. The same is repeated at each depth. This allows accurate comparisons among the climatologies of different seasons for each depth.
