Southern Ocean State Estimation
A modern general circulation model, the MITgcm, is least squares fit to all available ocean observations. This is accomplished iteratively through the adjoint method. The result is a physically realistic estimate of the ocean state. SOSE is being produced by Matthew Mazloff as part of the ECCO consortium and funded by the National Science Foundation. Computational resources are provided in part by the NSF TeraGrid.
For more information on the adjoint method see C. Wunsch and P. Heimbach, 2007: "Practical Global Oceanic State Estimation." Physica D. (pdf)
