World’s deepest underwater cave discovered
Polish explorer makes discovery 404 metres down near Czech town of Hranice
WARSAW, POLAND— A team of explorers say they have discovered the world’s deepest underwater cave, 404 metres down, near the eastern Czech town of Hranice.
Polish explorer Krzysztof Starnawski told The Associated Press Friday he felt like a “Columbus of the 21st century” to have made the discovery.
Starnawski, 48, found the cave Tuesday in the flooded limestone Hranice Abyss, which he has explored since 1998.
He scuba dived to a narrow slot at 200 metres’ depth and let through a remotely-operated underwater robot, or ROV, that went to the depth of 404 metres.
In 2015, Starnawski himself passed through the slot and went to 265 metres’ depth, realizing that was still far from the bottom and that the cavity was widening.
Speaking on the phone from his home in Krakow, southern Poland, he said that the discovery Tuesday makes Hranice Abyss the world’s deepest known underwater cave, beating the previous record-holder, Italy’s Pozzo del Merro flooded sinkhole, by 12 metres.
Diving in the cave is a challenge because of muddy areas and cold water of some 7 degrees Celsius, as well as a mineral composition that dam- ages the equipment and hurts any exposed skin, he said.
“But that is the only price to be paid for this discovery and it was worth paying,” he said.
On Saturday he will dive to 200 metres to bring back the robot though the narrow passage. The device was specially made for the expedition by a Polish firm, GRALmarine.
He said National Geographic, which first reported the discovery, covered about 20,000 ($29, 539 Canadian) of the cost for the project.
