3. Management and Conservation of Ecosystems 



Department of Commerce— The Manned Undersea 

 Science and Technology Program contributes to basic 

 research in the marine ecosystem by providing the 

 capabiUty for undersea research and developing the 

 technology to allow direct observation and analysis of 

 the undersea environment. This work is accomplished 

 primarily through the use of undersea laboratories and 

 manned research submersibles.

Department of the Interior— Research is conducted 

 on the management and conservation of ecosystems, 

 both as a goal in itself and as an accessory function to a 

 broader mission. The Bureau of Outdoor Recreation 

 studies potential new recreation areas, including wild 

 and scenic river additions whose ecology must be 

 evaluated before decisions are made regarding their 

 use. The Geological Survey performs research on 

 stresses related to water based ecosystems; the Office of 

 Water Resources Research supports a number of 

 individual research projects deahng with areas similar 

 to those studied by the Survey. The Bureau of Sport 

 Fisheries and Wildlife, the Bureau of Land Manage- 

 ment, and the National Park Service are all charged 

 with specific responsibilities in ecosystem preserva- 

 tion and management.

Smithsonian Institution— The management and 

 conservation of an estuarine ecosystem is being studied 

 in the Rhode River estuary in Chesapeake Bay. The 

 subestuary is being described and measured biolog- 

 ically, chemically, and physically. Interrelationships 

 are being studied and a model is being developed. The 

 movement of biocides, fertilizers, and sediment 

 introduced from the watershed is being measured in 

 relation to preservation and conservation. Ecological 

 studies on marine coastal and coral reefs are being 

 conducted in Panama and in other areas.
