Abstract
In recent years the nature of the Kara Sea is greatly influenced by human economic activity. It is stipulated mainly by extensive development of the Kara Sea coastline and by huge deposits of hydrocarbons on its shelf. An attempt to estimate the entropy of temperature and salinity distribution in subsurface layer of the Kara Sea water area has been made in this study aided by the newest geoinformational methods of study (Quantum GIS Desktop program complex). The computation and cartographic modeling of this problem show that the greatest values of entropy indices are registered within littoral and shelf regions. It can testify to the high diversity of these water areas and it is necessary that special (nature protection) regimes of nature use should be set up.
