“…Pix4Dmapper and Agisoft Metashape implement high-tech algorithms of objects detection and their spatial location determination, as a result of the photogrammetric processing of a series of aerial photographs taken during UAV flights. Based on these data, using ArcGIS software, it is possible to create 3D DEMs and conduct the monitoring of their changes in time [35,38,90]. All mentioned methods were used in our study.…”

This article describes the results of an Arctic expedition studying the new giant gas blowout crater in the north of Western Siberia, in the central part of the Yamal Peninsula in 2020. It was named C17 in the geoinformation system “Arctic and the World Ocean” created by the Oil and Gas Research Institute of the Russian Academy of Sciences (OGRI RAS). On the basis of remote sensing, it can be seen that the formation of the crater C17 was preceded by a long-term growth of the perennial heaving mound (PHM) on the surface of the third marine terrace. Based on the interpretation of satellite images, it was substantiated that the crater C17 was formed in the period 15 May–9 June 2020. For the first time, as a result of aerial photography from inside the crater with a UAV, a 3D model of the crater and a giant cavity in the ground ice, formed during its thawing from below, was built. The accumulation of gas, the pressure rise and the development of gas-dynamic processes in the cavity led to the growth of the PHM, and the explosion and formation of the crater.

Применение технологий аэрокосмического дистанционного зондирования Земли (ДЗЗ) при изучении процессов взрывной дегазации Земли в Арктике предоставляет уникальные возможности трехмерных (3D) построений. Показано, что при полевых исследованиях применение беспилотных летательных аппаратов (БПЛА) становится одним из важнейших инструментов исследования кратеров выбросов газа и потенциально опасных многолетних бугров пучения. Исследования с БПЛА проведены на ряде объектов Ямала, при этом на Бованенковском кратере С17, образовавшемся в мае - июне 2020 г. получены особо важные результаты. Здесь впервые был создан высокоточный цифровой двойник подземной полости и кратера выброса, позволяющий проводить обследование подземного пространства в виртуальной реальности. Полученные результаты способствовали завершению семилетнего периода фундаментальных научных исследований генезиса опасного природного явления мощных выбросов газа в Арктике, проводимых ИПНГ РАН.
