Boundary of Creation (27 minutes)-This film describes the 

 efforts of U.S. and French scientists in Project FAMOUS 

 to understand the ever-changing geology of our Earth, 

 particularly the midocean ridges off the Azores. The 

 picture features the probes of the submersible ALVIN in 

 the ocean depths and also portrays research in Hawaii 

 and Iceland. F

Cycle in the Sea (5 minutes)-Thanks to the motions of 

 wind, water, and the Earth itself, life in the oceans con- 

 tinuously renews itself. Here is an important story of the 

 balance in the world's ecosystems and its study off the 

 coast of Oregon. F 



Desert in the Deep? (5 minutes)-That the ocean floor is no 

 desert is beginning to be realized. But the varieties of life 

 forms, from simple organisms to sharks measuring 4 feet 

 between the eyes, were unsuspected until scientists went 

 to sea with cameras able to explore the very deepest 

 reaches of the ocean. F 



Pastures of the Sea (5 minutes)-Food chains in the sea 

 like food chains on land depend on plants to use the Sun's 

 energy to convert chemical nutrients into food. To under- 

 stand, and perhaps better use, the resources of the sea, 



we have to understand its interlocking life cycles. Science 

 is looking at the beginning of the sea's food chain; this 

 film looks at the science. F 



Rivers of the Sea (27 minutes)-A sea-going expedition 

 leaves Tahiti to gain a better understanding of the oceans 

 and their chemistry-knowledge that is vital in preventing 

 ocean pollution, improving commercial fishing, and under- 

 standing climatic conditions. It joins scientists working at 

 sea and in land-based laboratories in California, New 

 York, and Miami. F 



Science and the Salmon Fishery (5 minutes)-Commercial 

 fishermen have learned by guess and by gosh where to 

 catch fish, but they do not often know why the fish are 

 where they are. A scientific experiment off the Oregon 

 coast is turning up explanations and, with the coopera- 

 tion of the coho salmon fishermen, is developing a system 

 of fishery predictions that seems to be paying off. F 



Test Tubes in the Sea (5 minutes)-Can our oceans con- 

 tinue to absorb the urban wastes, oils, and chemicals we 

 discharge into them — or is there a point of no return? An 

 international team of scientists and engineers is trying to 

 find out by measuring pollutants in the sea. Their efforts 

 are giving us a major tool that will help us understand how 

 these contaminants affect the ocean food chain and an 

 indication of how far we can go in continuing to pollute 

 the sea. F
