Close to the Czech Border town, a group of Czech researchers, under the guidance of Krzysztof Starnawski managed to find a cave, which, as shown by further study, is the deepest known to date. It reaches a depth of 404 metres, which is 12 meters longer than the previous one “holder of record” — the Italian Pozzo del Merro.
Flooded karst cave was discovered long ago, in 1999, but that the details of the study, specialists took a lot of time. However, the fact that the cave promises to be profound, experts suspected at once. As scholars have noted, it formed a rather unusual way — saturated with carbon dioxide, the bubbles of hot air spewing from her depths like lava during the eruption of the volcano, pushed to the surface many stones (and forced to scratch exposed skin researchers).
The most detailed study of the cave Krzysztof Starnawski with his team began two years ago. In 2014, scientists came into the cave at 200 meters — then it was assumed that this depth is the bottom of it. Instead, the researchers saw a narrow passage, going deeper. This cleft was sent a special robot, with which the data was obtained that the depth of the cave reached and 384 metres by 8 metres behind the Italian “competitor.” Some time later, the researchers found that the entrance to the cave was enlarged and tried again to measure its depth. During first measurements, it was even smaller than the original — 370 meters (as the researchers suggest, is due to the fact that at the bottom of the cave recently formed breakaway debris from the top. However, further research with more sophisticated remotely operated underwater vehicle helps fix a new record of 404 meters, reports National Geographic.
According to Krzysztof Starnawski, he deliberately did not swam in the depths of the cave himself, and gave this work to robots — his goal was not to go to unprecedented depths, and to carry out research and data collection for special devices would be better.
