Geoecological Zoning of The Bays of The White Sea

Abstract

Zoning of the White Sea subjects to intense anthropogenic influence. Previously the author in his works performed ecological zoning the entire water area of the sea according to average annual and seasonal values. Large cities are located on the shores of the bays, in which enterprises of the forest, woodworking, engineering, chemical industry are located, oil terminals are located in three of the four bays. Zoning is carried out by means of point classifications. Statistical data of Roshydromet and text data from literary sources were used as initial data. For the study, 27 influencing factors were selected, divided into 6 groups. The water area of the White Sea is divided into 88 equal sections. Calendar seasons have been selected. The final results of calculations are shown in 4 figures. Analysis of seasonal maps of the bays of the White Sea showed that environmental tensions in the spring are highest, in the summer - the least. The main factors influencing this result are water pollution and oil pollution.
