RESULTS OF AERIAL, SPACE AND FIELD INVESTIGATIONS OF LARGE GAS BLOWOUTS NEAR BOVANENKOVO FIELD ON YAMAL PENINSULA

The paper shows the study of Arctic subsoil degassing in regions with permafrost resulting in gas blowout craters formation. The study is based on aerial and field data from expedition on one of the gas blowout craters near Bovanenkovo field. A 3D-model of the lake formed in the place of the crater and surrounding land made from echo sounding and GPS data is shown. 80 newly formed objects surrounding the crater studied, including small lakes around the main crater. The results of satellite monitoring of crater shoreline change since the first foundation till the present day is presented in the paper.
