An incredible new report indicates that scientists may have just found the deepest underwater cave in the world.
Polish cave divers may have found the deepest underwater cave in the entire world Hranicka Propast in the Czech Republic has been explored many times, but it was until scientists were able to send an underwater robot down there that they were able to better estimate the true depth of this huge cave.
What they found was incredible: the cave plunge an astonishing 1,325 feet deep, which beats the record held by Pozzo del Merro, a cave in Italy that stretches 1,286 feet down. The research team used a remote operating vehicle to access the cave, according to a National Geographic report.
The dive on Sept. 27 was one of a series of devices that have been taken in the last two decades.
Scientists are intrigued by the cave because it is utterly unique. Most caves are formed by rain coming down, but this cave was formed from hot mineral water that bubbles up from the bottom, making it a striking and unusual geological feature that is quite rare to see.
Polish diver Krzysztof Starnawski, who led the expedition, told National Geographic that the team was trying to go beyond what other divers had done.
“They all had the same goal: to explore the cave further and deeper,” he was quoted as saying. “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.
“During this push, the most important part of the job was done by the robot,” he continued. “I scuba dived down to 200 meters just before the ROV’s deployment to put in the new line for the robot to follow. The goal was to give the ROV a good start from there to the deepest part of the cave. I came back to the surface, and then we went down with the robot to a depth of 60 meters (197 feet). From there, the team at the surface navigated it, via fiber-optic cable, down along my new line to 200 meters deep. Then it went down to explore the uncharted territory—to the record-breaking depth of 404 meters.”
