Researchers from the Russian Geographical Society have set a world record for ice diving, according to the Russian news agency TASS.
Divers descended to a depth of 102 metres while exploring the northerly White Sea, enduring a water temperature of minus six degrees Celsius. The team, consisting of four daredevils Maxim Astakhov, Alexey Gubin, Alexey Polishchuk and Igor Artemyev spent a total of 80 minutes under the freezing water.
Their expedition, part of the "13 Seas of Russia" project, is seen as an important step in preparation for the Arctic expedition.
Ice diving is also considered as much more difficult than regular diving as divers have limited visibility and can’t quickly rise to the surface.
