World’s deepest underwater cave found…


Polish explorer Krzysztof Starnawski and his team of explorers recently reported that they have found the world’s deepest underwater cave system, located in the Czech Republic. The flooded fissure extends down to at least 404 meters, or over 1,300ft! His team of technical divers have been making extensive expeditions into the upper regions of the cave (down to 200 meters) and sent a remotely operated vehicle (ROV) to explore the deeper regions. The robot ROV reached a depth of 404 meters before running out of supply cord, with the bottom nowhere in sight.

This beats out the Pozzo del Merro in Italy by at least 12 meters, which was originally the deepest known sink-hole in the world.

Along with the host of regular difficulties associated with deep diving, the Hranice Abyss (as it is now named) also boasts challenges of cold 15 degree Celsius waters (59 degrees Fahrenheit) and muddy bottoms, potentially creating blackout conditions if stirred up. The chemical composition of the water also creates hazards when exposed to skin and can easily damage expedition and dive equipment.

There is still much more to be explored in the Hranice Abyss and future expeditions are bound to yield additional records. Depth predictions currently estimate that it could go as deep as 800 meters (over 2,600ft).
