Specialists of «Gazprom VNIIGAZ» and the Institute of oil and gas geology and geophysics (named after A.A.Trofimuk) at the Siberian branch of the RAS conducted field work in the district of the funnel, which had formed in Yamal near Bovanenkovo field.
The scientists fulfilled the set of operations. They allow analyzing different hypotheses of appearing of the giant funnel. The researchers conducted GPS-survey and geodesic measurements, researched landscape and geomorphologic peculiarities of the funnel, studied damage of vegetation and soil covers, conducted mapping of cracks, subsidence of surface and areal of soil scattering, as the press-service of the company informs.
The conducted areal magnetic survey, which allows finding anomalies of magnetic field, rejects the meteorite hypothesis of appearing of the funnel. The scientists will inform about other conclusions later.
As we should remind, this summer helicopter pilots found the funnel with the diameter 60 meters and the depth 50 meters in tundra. They put the video into the Internet. It aroused interest of specialists. Scientists from the Institute of Oil and Gas Problems at the Russian Academy of Sciences, the Institute of the Earth Cryosphere at the Siberian branch of the RAS and the scientific center for exploration of the Arctic arrived to the place of the funnel twice.
