10 hours under the ice now! How Tatarstan divers get ready for record

The underwater research team of the Russian Geographical Society named after Aleksey Leonov has been in the federal news again. If last March the divers were under the water for 6 hours without any health damage, this time the team is getting ready to set a new world record – to immerse for 10 and more hours. It will be possible to know what the outcome will be on 30 January. Tatarstan journalists managed to see the preparation during a press tour to the expedition camp.
