measure the time difference between the laser beam reflection from the water surface and 

 from the bottom. The problems and potential of the laser are described. The best accuracy 

 can be achieved by a combination of the laser and multispectral imagery techniques.

Report describes a study of photo applications in an investigation of the coastal 

 environment. Studies include water depth penetration, benthic material characteristics, and 

 water body properties. Color, color infrared, and 70-mm multispectral photos taken at 

 different altitudes were examined. Color photos with one stop number overexposure gave 

 better depth penetration and bottom material deUneation capabihty. Six methods of image 

 enhancement were examined and results are described. Photos were used for mapping 

 bottom vegetation in an area of temperature cUmate and turbid water. Benthic material 

 mapping from photo interpretation was compared with field surveys. Attempts were made 

 to correlate water color with phytoplankton and sediment concentrations.

Article describes a procedure to use photos in evaluating waste concentrations, dispersion 

 processes, and current patterns near an outfall discharging wastes in the ocean. Advantages 

 of this procedure as compared to field sampling from a boat are discussed. The theory and 

 procedure for determining waste concentrations (as reflected by a dye tracer) from 

 measurements of image density in three spectral bands on color photos are given. Analysis 

 of time-lapse photos provides a method to examine the changes in effluent plume position 

 and concentration with time. Movement of the effluent plume indicates current patterns. 

 Photo measurement and computation procedures were computerized and plots of the study
