Data Assimilation Experiments
1)Optimal Interpolation (OI) assimilated all T/S and current data into the model. T/S was added as the monthly base, and currents were implemented as hourly input.  The OI experiment has been run for years 1995-2006.

2)Ensemble Kalman Filter was focused on twin experiments in the Northeast Channel area, and now is being extended to cover the entire Gulf of Maine domain.
