done in real-time; however, while the resolution of the cathode ray tube 

 enhanced color image is substantially better than commercial color television, 

 it cannot provide the high resolution of the photographic process. 



The present and future activities of our group, relating to ocean color, 

 include planning and flying 4-band multispectral photography with our own 

 camera for the practical testing of suitable films, filters and processing 

 chemistry, to improve the recording of small color changes in the water, and 

 aid in the selection of spectral bands for maximum depth penetration. Con- 

 tinuing programs include the separation, enhancement and analysis of Gemini 

 and Apollo photography for oceanographic subjects such as bathymetry, sedi- 

 ment flow patterns, shoreline discrimination, emphasis of water color changes 

 for delineating current boundaries and areas of upwelling, enhancing bottom 

 features and topography, clarifying wave diffraction patterns. 



Methods of enhancing color differences are also under continuous development 

 and improvement in our laboratory.
