Abstract : Eleven images of ocean subjects selected from Gemini and Apollo 70 mm color photography were enhanced by Photo-optical means, producing false-color contours of small changes in density and color. Bathymetry, sediment concentrations and flow patterns are delineated by the process, interpretation and information yield improved. Correlation with charted depth contours was found, in one instance to 20 fathoms, although none of the photography was optimum for water penetration. The utility of space photography and enhancement processes for determining relative water depths and updating charts is apparent from this and previous work. The results of spectral filter tests for water penetration conducted under the same contract and reported in detail earlier are summarized. (Author)
