Into the Abyss.... Man and Robot teamed up to discover the world's deepest underwater cave in Czech Republic Explorers in the Czech Republic have just completed an expedition to the underwater cave Hranická Propast - also known as the Hranice Abyss - verifying for the first time since its discovery in 1999 that it really is the deepest underwater cave on Earth. The team, led by Polish diver Krzysztof Starnawski, managed to reach a depth of 404 metres (1,325 feet) using a remotely operated vehicle (ROV), which means this limestone cavern is 12 metres (39 feet) deeper than the second deepest underwater cave that we know of - Italy’s Pozzo del Merro. Video from the ROV showed Ancient trees captured along the sloping ridges of the Hranice Abyss(photo: Krzystof Starnawski/Facebook) The most recent expedition, which was sponsored in part by National Geographic, is the result of over two years of diving. Back in 2014, Starnawski thought he had reached the bottom of the cave at a depth of 200 metres (656 feet). As Kat Long reports for National Geographic, with further investigation, Starnawski found an extremely narrow 'squeeze passage' that gave way to a gigantic, pitch black, vertical tunnel, which he tried to explore with a probe, but ran out of line at a depth of 384 metres (1,260 feet). In 2015, Starnawski conducted another dive in the cave, revealing that the passage he managed to stick a probe through last time had widened, which allowed him to actually swim through. While inside this black abyss, he managed to reach a depth of 265 metres (869 feet) where he unleashed another probe, finally managing to reach somthing solid at a total depth of 370 metres (1,214 feet) - possibly landing on top of fallen debris. According to Long, during the most recent expedition last week, the team managed to use an ROV to fully explore the cave, verifying that it is, in fact, the deepest known cave in the world, at a depth of 404 metres (1,325 feet). "As the expedition leader for the last several years, I've prepared the equipment and the route in and out for the ROV’s dive, so the ROV could go beyond the limits of a human diver, and get through the restricted passage and between the fallen logs and trees," Starnawski told National Geographic.

His team deployed the ROV, and he accompanied it down to 60 metres (197 feet). "From there, the team at the surface navigated it, via fibre-optic cable, down along my new line to 200 metres deep. Then it went down to explore the uncharted territory - to the record-breaking depth of 404 metres," he told National Geographic. "The ROV that reached 404 metres has a depth gauge that was tested and certified by our state commission, so we are 100 percent sure the measurements were accurate." While the team is sure that the cave is the deepest known in the world, there are still many things to learn about it. It's thought that the limestone cavern was created by bubbling hot mineral water filled with carbon dioxide that slowly formed a tunnel over time, but further research is needed to fully understand its formation. "This cave is very unique because it’s like a volcano, formed from hot mineral water bubbling from the bottom up, rather than rain coming from the top down like most caves," Starnawski explained to Mark M. Synnot at National Geographic last year. "There are probably only three caves like this in the world. There is nothing typical about this cave, and every dive we make new discoveries."

How about letting people know about this discovery? The underwater cave's "actual" bottom hasn't been found out yet.... It's still "bottomless" |

PHOTO: The Hranicka Propast or Hranice Abyss in the Czech Republic is now the deepest Polish explorer Krzysztof Starnawski, who led the team, told The Associated Press on Friday that he felt like a "Columbus of the 21th century" to have made the discovery near the Czech town of Hranice. Starnawski, 48, determined Tuesday that the flooded limestone Hranicka Propast, or Hranice Abyss, which divers, including him, have explored for decades in its upper parts, was at least 404 meters deep. He scuba dived to a narrow slot in the rock formation at 200 meters down, then sent a remotely operated underwater robot, or ROV, that went to the depth of 404 meters, or the length of its cord, but still did not hit the bottom. 1 Like |

Some of the world's other deep dives: - Pozzo del Merro in Italy (392 metres) - Zacaton in Mexico (339 metres) - Vrelo Cave in Macedonia (330 metres) - Boesmansgat in South Africa (270 metres) - Dean's Blue Hole in the Bahamas (202 metres) The Hranice "Abyss" (Aka. Hranicka Propast) has been surveyed numerous times by Polish explorer Krzysztof Starnawski over the last 20 years, but Mr Starnawski had never, until now, been able to measure beyond a depth of 370 metres (1,214).
