Optical Variability and Bottom Classification in Turbid Waters: Phase II

Abstract

Real-time determination of the optical and bathymetric climate available for operation of various naval assets in the coastal zone using a mixture of AUV, ROV, surface-vessel, fixed moorings/towers, and air/space-borne observational assets. Advanced heat-budget modeling applicable to coastal regions as well as methods for early detection of K. brevis (red-tide) and other algal blooms. Remote determination of inherent optical properties and bottom characteristics will be accomplished for input and validation data for predictive visibility, heat budget, and primary production models and for use in asset selection for naval operations. The development of optical methodologies valid for Case II coastal waters for the remote determination of water and bottom optical properties including visibility, water amd bottom optical absorption, algal concentrations, bathymetry, bottom albedo, vegetation cover, and bottom structure are being pursued. These include interpretation of hyperspectral, high-resolution imagery from aircraft and satellites, development and deployment of suites of small instruments on remotely operated and autonomous underwater vehicles (ROVs, AUVs) and a multi-disciplinary network of moored sensors, and development/application of radiative transfer models and algorithms for predicting optical properties and extracting information from the remote data. Effects of vertical structure in the optical properties (e.g. river plumes, suspended sediments) and turbidity must be recognized for the data retrievals to be accurate, and the instruments and methodologies necessary to quantify such structure will be developed and utilized on underwater vehicles and moorings.
