ИСТИНА

Economic development of the seas is accompanied by growth of anthropogenous influence on sea ecosystems. Ecosystems of the Arctic seas are in this respect most vulnerable. They are distinguished by natural vulnerability and the increased sensitivity for loadings. Problems of steady development of a coastal zone of World ocean have sharply become aggravated in second half of XX century, and obviously, will keep the actuality in the future. The coastal zone differs specificity of hydrochemical and hydrological modes, faunistic complexes, bioproduction processes, the greatest efficiency and a high biological variety of ecosystems. Coastal waters accept and assimilate all volume of the pollution, acting from river pools and directing from sea coast, that can result to degradationing changes in sea ecosystem.
