Paper describes the remote sensing interpretation problems of oceanographic features 

 (including nearshore features). Color separations (enhanced images) in the blue and green 

 wavelength bands obtained from Apollo IX satelMte photos of coastal areas in North and 

 South Carohna illustrate the subsurface information available in these bands. Multispectral 

 photos of the submerged Ben Franklin submarine, taken with a four-lens camera, show use 

 of the blue part of the spectrum in appHcations related to the penetration of light in water 

 bodies. Author concludes that wavelengths shorter than 500 millimicrons can improve the 

 quantity and quality of the information from photo interpretation of oceanographic 

 features.

 A description of two remote sensing techniques for determining water depths is presented. 

 Data collection and processing techniques to make shoal detection and water depth 

 determinations automatic and accurate is emphasized. The techniques are computer 

 processing of multispectral imagery and optical processing of aerial or satellite photos to 

 determine changes in wave refraction patterns. The multispectral imagery approach is based 

 on the spectral signature of the bottom reflection at two different wavelength bands. This 

 analysis can be performed by computer processing and a map of water depths printed by the 

 computer. Wave analysis techniques use optical processing to develop the Fourier transform 

 of the wave patterns on the photos. Wave direction and wavelength are determined from 

 these transforms. A laser ranging technique for water depth measurement is discussed.

Report is a study of wave patterns on an ApoUo 6 satellite photo. The photo covered about 

 10,000 square miles in the Atlantic and showed a clear view of the wave patterns. Trough to 

 trough wavelength measurements were made for 1 ,000 waves. Distribution of wavelengths 

 was analysed in relation to weather conditions before photo exposure. There was good 

 correlation of wavelength distribution with wave propagation theory. Potential use of
