COASTAL WATER PENETRATION USING MULTISPECTRAL PHOTOGRAPHIC TECHNIQUES,
Abstract
The exposure and spectral filtration to maximize the depth at which submerged objects can be detected has been established for northern coastal waters which contain large quantities of suspended particulant matter. Quantitative measurement of the comparative penetration capability of selected filtration shows that the log exposure latitude in the green spectral band is twice that of the red and three times that of the blue band. The optimum exposure of underwater objects for all spectral bands was found to occur when the surface was overexposed to place the ambient water illumination at least at unity density on the recording emulsion. The underwater log exposure latitude was observed to be reduced by one-half for each five feet increase in depth. (Author)
