Published in Deep-Sea Research II, v56 p188-198, 2009. Prepared in collaboration with Naval Postgraduate School, Monterey, CA. Prepared in collaboration with MBARI, Moss Landing, CA; Woods Hole Oceanographic Institution, Woods Hole, MA; and Scripps Institution of Oceanography, La Jolla, CA. Glider observations were essential components of the observational program in the Autonomous Ocean Sampling Network (AOSN-II) experiment in the Monterey Bay area during summer of 2003. This paper is focused on the impact of the assimilation of glider temperature and salinity observations on the Navy Coastal Ocean Model (NCOM) predictions of surface and subsurface properties. The modeling system consists of an implementation of the NCOM model using a curvilinear, orthogonal grid with 1 -4 km resolution, with finest resolution around the bay. The model receives open boundary conditions from a regional (9 km resolution) NCOM implementation for the California Current System, and surface fluxes from the Coupled Ocean Atmosphere Mesoscale Prediction System (COAMPS) atmospheric model at 3 km resolution.
