Paper is a study of the exposure and spectral filtration conditions to determine the depth at 

 which submerged objects can be detected. Study was to determine water penetration of 

 wavelength bands in northern coastal waters which contain large quantities of suspended 

 particles. A four-lens multispectral camera and filters were used to produce photos exposed 

 with light in wavelength bands. Photos were taken of two identical target arrays with four 

 color panels and six gray panels. One target array was placed at the surface and the other 

 was submerged. Data analysis procedures are given. Data indicated that the green spectral 

 band had twice the water penetration of the red band and three times that of the blue band. 

 One problem with the submerged array was the growth of algae on the panels which 

 affected the data at greater depths.

 Report describes a technique for determining ocean currents by photogrammetry using 

 time-lapse color photos. Test was conducted in the Gulf Stream off the coast of South 

 Carolina in 1965. Fifteen floating targets were distributed at about 1,500-foot intervals 

 along a Une perpendicular to the Gulf Stream. Nine targets were red or white wooden panels 

 and six targets were formed by aluminum powder. A single -photo technique in which a ship 

 provided azimuth ground control and aircraft altitude was used to compute the photo scale. 

 This was a feasible method of current velocity measurement and a satisfactory accuracy was 

 obtained. Report also describes a two-photo method. Factors that affect accuracy of current 

 velocities from photogrammetry is included.
