Monoc programme: Scientific substantiation of the integrated global ocean ecological monitoring system.

Man's exploitation of the World Ocean continues to increase both productively, i.e., utilization of fisheries and natural resources, and counterproductively, i.

[Study of sea water pollution by determining the mutagenic activity of sediments].

Extracts from bottom sediments sampled in the Bering Sea and in certain regions of the Pacific Ocean were studied. Benzene and acetone-hexane extracts were tested for mutagenicity by Ames' bacterial test-system using the TA 98 and TA 100 Salmonella typhimurium strains. Extract from 4 stations of the 10 studied ones produced significant increase in the number of revertants.

Ecology and the problems of World Ocean integrated global monitoring.

Modern ecological state of the World Oceans is analysed, stressing the need for organization and development of a scientific basis for global ocean monitoring. The tasks and basic principles of integrated global ocean monitoring are described.Complex of natural processes determines the assimilative capacity of marine ecosystems, which can serve as a basis for the study of ecological reserves of the World Oceans and ecological rationing of the anthropogenic impact.
