Russia claims world-record dive Russians in landmark Baikal dive
(about 1 hour later)
Russian scientists say they have broken the world record for the deepest dive in a body of fresh water, plumbing the depths of Lake Baikal in Siberia. Russian scientists say they have reached the bottom of the world's deepest body of fresh water - Lake Baikal in Siberia.
Russian news reports said two manned mini-submarines successfully plunged 1,680m (5,512ft) to the lake's bed. However, they did not break the record for the deepest freshwater dive, as was originally reported.
However, there is still no official confirmation of the depth of the dive. The Mir-1 submarine descended 1,580m (5,184ft), organisers said, and not a record 1,680m as was earlier claimed.
The mission is part of a two-year plan aimed at conserving the ecosystem of Lake Baikal, which contains about one-fifth of the world's fresh water. The mission is part of a research project at Lake Baikal, which contains about 20% of the world's fresh water.
The area was declared a Unesco World Heritage site in 1996. The lake was declared a Unesco World Heritage site in 1996.

The Mir capsules are already in the record books for their undersea expeditions - descending to depths greater than 4,000m. However, it was later confirmed that the dive did not go as deep as first thought.
"There was no record... We'll try again," expedition leader Artur Chilingarov, a Russian parliamentarian and celebrated Arctic explorer, said after the dive.

The mission team plan to make up to 60 dives in total.
The current record of 1,637m was set in Lake Baikal in the 1990s.

The two 18-tonne mini-submarines were designed to operate in seawater - but have shed hundreds of kilos to make them buoyant enough in less dense fresh water.The two 18-tonne mini-submarines were designed to operate in seawater - but have shed hundreds of kilos to make them buoyant enough in less dense fresh water.
Mr Chilingarov also led a team of scientists to the North Pole in August last year - where they controversially staked Russia's claim by planting a flag on the seabed.Mr Chilingarov also led a team of scientists to the North Pole in August last year - where they controversially staked Russia's claim by planting a flag on the seabed.

Environmentalists had expressed concern that Russia intended to exploit the lake's mineral wealth, but expedition leaders insisted the mission was for research and conservation purposes only.Environmentalists had expressed concern that Russia intended to exploit the lake's mineral wealth, but expedition leaders insisted the mission was for research and conservation purposes only.
