NASCar-OPS Project Main Page

The NASCar-OPS Sea Exercise 2017 occurs in the Arabian Sea in February-April 2017. In collaboration with the DRI-NASCar team, our objectives are to utilize the MIT Multidisciplinary Simulation, Estimation, and Assimilation System (MSEAS) to: (i) forecast the regional high-resolution ocean fields and their probability, using our Error Subspace Statistical Estimation methodology; (ii) utilize these fields to forecast the reachability sets, reachability fronts, and time-optimal paths of underwater vehicles including gliders and floats; (iii) forecast the uncertainty of such reachability fields and optimal paths. We thank Dr. Andrey Shcherbina for his input, the HYCOM team for their real-time ocean fields, and the NCEP GFSp25 and NAVGEM 0p5 teams for their real-time atmospheric flux forecasts.

This research is sponsored by the Office of Naval Research.
