Sub-mesoscale Ocean State Estimation in Shelf/Slope Regions Using Variational Data Assimilation to Integrate Ocean Observing System Data: Application to SW06

Abstract

The long term goal is to develop a robust ocean prediction system for the North East US coast that efficiently exploits all the available observational platforms. The system will produce reliable hindcasts of the state of the ocean, and perform also in an operational mode assimilating all available observations in real time and provide estimates of the uncertainty in the deterministic forecast. Objectives are: To develop a prototype of an operational analysis and dynamical forecast system for mesoscale and sub-mesoscale variability in a coastal transition zone: The Mid-Atlantic Bight (MAB). The system should use advanced data assimilation and adjoint techniques to integrate a high-resolution 3- dimensional coastal model (The Regional Ocean Modeling System; ROMS) with data from a coastal observing system comprised of remotely-sensed Sea Surface Height Anomaly (SSHA) and Sea Surface Temperature (SST), surface current from HF radar (CODAR) installations, autonomous gliders, moorings and XBT/CTD acquired during the ONRs Shallow Water Acoustics 2006 (SW06) field program.
