The Russian Geographical Society's research diving team plans to make the deepest ice dive ever to a depth of 100 metres in the White Sea.

"The expedition in the White Sea will last from February 29 to March 7. The divers plan to reach a depth of 100 meters, which will be the deepest ice dive ever. This is part of the 13 Seas of Russia large-scale project and a key preparation stage for an expedition to the Arctic Region," the RIA Novosti news agency reported, citing the Russian Geographical Society's branch in Tatarstan.

The divers will test Russian underwater equipment at record depths under the ice.
