Abstract

The function for visualization of information is observed as common property of satellite pictures. Due to reproduction of visual images of territory, satellite pictures reflect not only ecosystems stage at moment of survey, but also their changes in time. That is especially important for investigation of Arctic regions, which ecosystems are filling state of dynamic unequilibrum, caused, from one site, by climate worming, and from the other site, with intensive familiarization of the Northern regions and inevitable anthropogenic impact. Satellite pictures, included into the paper, are reflect the both kinds of changes. Sea ice area reducing in warming conditions is illustrated by materials of satellite survey of the Northern ice cap for years of the most area decreasing. Multitemporal images had fixed retreat of shores with underground ice, as result of thermоabrasion, thermal erosion and thermal denudation processes development. Special attention is given to forms of permafrost relief, which reflects at images of very high resolution: polygonal relief of various kinds and stages of development, pingos, dally, thermal erosion forms. Forming of river ice fields, thermokarst lakes, gas emission craters out are characterized. Impact of entrails of the earth exploration to woundable arctic nature is shown at examples of mines in the Khibin mountains and oil platform at shelf of the Barents Sea. Strong examples of vegetation degradation are given for regions of Norilsk and Monchegorsk towns, where technogenic wastes were formed under cupper-nickel fabrics sulfur smokes. These materials show strong necessity of using satellite images for investigation of adaptive solutions for arctic ecosystems conservation and defense.
