Deeper than expected, at least 450 metres, is the deepest water cave known in the world, discovered by a Polish diver and his team in 2016 in the Hranes Valley in the eastern Czech Republic.
An international team – including Hungarian, Portuguese and Serbian speleologists – will make new measurements with a special robot in a mine cave in Moravia, where in 2016 it was possible to descend to 404 meters using a similar remote-controlled device.
With the measurements made on Monday, it was possible to descend to a depth of 450 metres, and only because the robot reached its maximum carrying capacity, said Michal Juba, president of the Czech Caves Association. The record was broken by 46 metres.

The famous Polish diver Krzysztof Starnowski, who dived 200 meters at that time, judging by the unusual shape of the interior of the rift, already believed at the time of its discovery that the cave could extend to a greater depth.
The dry part extends at the entrance to the Hranisi Valley at a depth of 69.5 meters in the ground. Regular scientific dives into the formation have been carried out since 1961.
The deepest known water cave in the world was a flooded crater called Pozzo del Merro in Italy with a depth of 392 meters. (MTI)
