Abstract

Summary

This publication presents the completed phase of the study, aimed at in-depth study of methane seepage and tectonic faults in the Black Sea. The main attention was paid to the areas of accumulation of methane seepage, at the bottom of the sea in the transition zone shelf-continental slope, which are recorded on the geological and geophysical data.

In times of increased seismotectonic activity in the Black Sea region (in Romania, Turkey, etc.), there is a heat flow in the fault zones, and in the areas of methane accumulation - the output of a certain volume of jet gas. This phenomenon is observed in satellite images in the form of clouds (of a certain type), which allows monitoring of methane outputs, heat flux in study areas, and allows the determination of periods of tectonic for activity by interpretation of satellite images. In this study, the series of MODIS images was monitored during periods of increased seismic activity (2000, 2015), the manifestation of which earthquakes in the Black Sea region.

When processing of the satellite images in GIS programs (SNAP, Q-Gis, etc.) as coursed by the anomalous cloudiness are observed in the area of the region of the paleo-delta of the Dnieper. Such cloudiness was formed (in the author’s opinion) due to the effect of the heat flow: the stream of methane from the depths to the bottom of the sea and further to its surface has a temperature difference relative to the environment (sea-air) and the heat flow rising to the lower layer of the atmosphere forms a condensate, which is observed in pictures as clouds.
