The goals of the proposed research are to 1 determine the regions within the water column that have the highest variability in optical and hydrographic parameters as a function of total water depth, 2 determine the likely physical and biological forcing mechanisms associated with observed variability. We have combined the measurement of the inherent optical properties and physical properties onto a single platform. This platform allows us to make simultaneous, detailed vertical profiles of optical and hydrographic parameters. In the shallow waters of the littoral environment this system can be used to make vertical profiles as often as every two minutes. This system was used to collect over 600 vertical profiles at Oceanside, California during October 1995. The sampling patterns include 3 transect lines perpendicular to the beach, a long time series at a single station, and 2 one hour time periods with intensive profiling at a single station. The profiling data is to be combined with the profiling and mooring data of Drs. Weidemann and Johnson of NRL to provide a comprehensive data set of optical and dynamic parameters. We propose to work with Drs. Weidemann and Johnson in the analysis of the combined data sets.
