Welcome to the Dartmouth Gulf of Maine Interactive Web Page!

Served by the Numerical Methods Lab at Dartmouth College
Sponsors: USGLOBEC NW Atlantic Program; UNH Sea Grant Program; Gulf of Maine Regional Marine Research Program.

Purpose: The purpose of this interactive page is to track the trajectory of drifters in the Gulf of Maine. The image on the left shows an example of the output that can be generated.

Currently, the drifter is influenced by the bimonthly tidal and residual velocity solutions found in "Georges Bank residual circulation during weak and strong stratification periods: Prognostic numerical model results," JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 101, NO. C3, PAGES 6469-6486, March 15, 1996, by Chris Naimie, and in Numerical Methods Report NML-95-3.

STEP ONE - Specify Parameters
Select a value from each for each of the following parameters:

Choose the bimonthly velocity solution set:

Enter the number of tidal cycles (must be an integer):

Specify how you would like your output plotted:

Would you like the drifters' vertical components fixed or passive?

Review the Results of a Previous Drifter Simulation

Purpose: This feature allows you to review results from a drifter simulation conducted since the first of the month at 0300 hours without having to re-run the program.

Instructions: Enter the simulation request number corresponding to the drifter simulation results you would like to view, then select "Submit Review Query".
