Surveying the Environment 



at or near the ocean surface. It is expected that major goals in the program 

 will be achieved in FY 1969 and that funding can thus be reduced in FY 

 1970 and beyond. 



Figure VIII. 1. A corner of East Africa and the Arabian Peninsula looked like this to 

 Astronauts Conrad and Gordon during the GEMINI XI flight on September 14, 

 1966. This is the season when the water level of the Red Sea (left) recovers from 

 the great loss by evaporation during the summer months. The warm {32 degrees 

 Centigrade) , highly saline {39-40 parts per thousand) waters begin to pour into 

 the western Gulf of Aden. As the Red Sea water is denser than that of the surface 

 layers, the new water sinks to a depth of about 200 meters. The eddy system outlined 

 in the photo above {right center) is the surface flow and turbulence caused by this 

 displacement. Such current systems may contain significant concentrations of fish.
