The weather forced the organizers to make some adjustments to the route of the first expedition, and the planned dives near the Circum-Baikal Railway have been moved due to heavy fog to Cape Listvyanichny and Cape Syty, north of the village of Listvyanka. First to dive was the Mir-2 submersible, crewed by Commander Yevgeny Chernyaev, Hero of Russia; Pilot/Observer Mikhail Slipenchuk, Chairman of the Board of Trustees of the Fund for Protection of Lake Baikal and Head of METROPOL Group; and Valentin Kazantsev, WWII veteran and sailor of the border guard. The hatches with the Mir-2 crew were battened down at 14:12, and the dive began at 14:26 local time. An hour later, the submersible reached the depth of 1450 meters. Currently, the Mir-2 is moving to the surface along the underwater slope.
The second submersible, Mir-1, piloted by Commander Viktor Nishcheta and observers Boris Danilov, Deputy Governor of Irkutsk Region and Sergei Yevchikom, Deputy Head of the Baikal Economic Forum Press Center, began to dive at 14:55. At 16:10 the submersible reached the 1402-meter depth mark.
