Recent progress under a NOPP-CODAE project on boundary conditions, data assimilation, and predictability of coastal ocean flows is reviewed. This research focuses on numerical model simulations of ocean circulation in the Oregon coastal transition zone (CTZ), the region extending several hundred kim offshore from the Oregon coast into the northern portion of the California Current System and the eastern interior North Pacific. The CTZ model is nested in the NRL NCOM-CCS model, and impact of these open boundary conditions on the CTZ model is examined. Atmospheric forcing is obtained from the NRL COAMPS product. Validation of the simulated coastal ocean circulation is provided by comparison with in-situ data sets from regional observational programs during 2000-2003 and with satellite and land-based remote-sensing observations.
