Coastal Water Optical Properties Prediction Development.
Abstract
Remote sensing concepts were evaluated for providing initial conditions to the Coastal Water Clarity predictive model. The most important water physical properties that strongly influence water optical properties are the concentrations of chlorophyll, sediment and dissolved organic matter. The currently available satellite multispectral imaging sensors do not have the required high sensitivity and small pixel size to be useful as a coastal water reconnaissance sensor. Two new satellite sensor concepts were developed to improve satellite capability. One concept uses a narrow swath sensor array with time delayed integration. The second concept utilizes a shot noise limited image intensified array. Aircraft operational attributes of quick reaction capability and ready availability when satellite coverage is not available were found to be complementary to the secure and covert coverage of satellite sensors. Aircraft may use laser sensors in addition to passive sensors and thereby make possible range gating for depth measurement and new interactions such as fluorescence and Raman and Brillouin scattering which offer non-site specific and simpler data interpretation algorithms.
