This document is a summary report which describes the current status of research on the laser Raman technique for the remote sensing of subsurface ocean temperature and salinity. The report, in three volumes, summarizes the state of the are as it relates to current Navy requirements, showing what it can be used for now, and what further work is required to develop the technique to its full potential. This document provides a management summary of the research program carried out by Computer Genetics Corporation over a number of years with support provided by several Government agencies including ONR, NRL, NASA nad NOAA. The aim of current research is to develop the capability to provide ships and aircraft with cost effective remote sensing instrumentation that can provide accurate and continuous subsurface temperature and salinity coverage. The spatial frequencies that would be available, on a quasi-synoptic basis especially from aircraft, would significanty overlap with those available from satellite observations of the sea surface, thus enabling comparisons and allowing predictive statements to be developed. The work to data has shown, by means of theoretical calculations, laboratory experiments, and field studies, that polarization Raman spectroscopy is feasible for the remote sensing of ocean temperature to a few tenths of a degree to depths of 50 to 100 meters in the open ocean.
