both countries, a careful scientific approach is necessary to 

 prevent exploitation of the natural resources of this unique area 

 of the World Ocean. Scientific information obtained in the 

 course of these joint ecological expeditions contributes to the 

 development of such an approach. 



In conclusion, it should be noted that fundamental studies 

 of northern polar marine ecosystems now have become even 

 more important considering the newly emerging problems of 

 global climate change. Ecological consequences of the predicted 



climate change on marine ecosystems may first manifest 

 themselves in arctic areas of the ocean and affect fundamental 

 natural phenomena, such as biogeochemical carbon cycling, 

 sea level rise, production/destruction processes of organic 

 matter, and others. Thus, these joint investigations of the role 

 of arctic ecosystems in global climate formation processes, 

 which were started by Soviet and American scientists, need 

 continued extension and development.
