A Czech-Polish expedition, led by the legendary Polish diver Krzysztof Starnawski, descended deep into the flooded limestone cave called Hranice Abyss and found it to be far deeper than previously thought. According to their measurements, the cave is 404 meters deep, 12 meters deeper than the previous record holder, 392-meter-deep Pozzo del Merro in Italy. encr@radio.cz (Cesky Rozhlas)webmaster@radio.cz (CRo Webmaster) https://english.radio.cz/sites/default/files/images/hranicka_propast_speleopotapeci.jpg?timestamp=1590564128 https://english.radio.cz/worlds-deepest-underwater-cave-discovered-czech-republic-8211622 Radio Prague International Radio Prague International radio.prague.int@gmail.com clean 0 1 2 3 4 5 6 7 8 9
