Cave diving regions of the world

1087:. With much of the Earth's water held in the form of glacial ice, the sea level fell hundreds of feet, leaving most of the Bahama banks, which are now covered in water, high and dry. Rain falling on the most porous limestone slowly filtered down to sea level forming a lens where it contacted the denser salt water of the ocean permeating the spongy limestone. The water at the interface was acidic enough to dissolve away the limestone and form the caves. Then, as more ice formed and the sea level dropped even further, the caves became dry and rainwater dripping through the ceiling over thousands of years created the incredible crystal forests of stalagmites which now decorate the caves. Finally, when the ice melted and the sea level rose, the caves were reclaimed by the sea. 690:. It is the only place in the world where you can dive or snorkel directly in a crack between two tectonic plates. The tunnel from the entrance of Silfra to the cave is commonly known as ‘The Tunnel’, due to the strong current that ‘flushes’ divers attempting to swim through. This tunnel is rarely dived due to the dangerous head-first vertical dive needed to pass through. The deepest part of the cave is at least 63 m (207 ft) deep, and has only been dived by a few people because of the narrow and unstable passages. 303: 757: 745: 511:, the river abounds with shallow water sources and a significant number of underwater caves. So far, 10 large caves have been registered, only five of which have been partially examined. Divers who have explored Klokot Spring have managed to reach a depth of 104.5 metres (343 feet; 57 fathoms), though the bottom of the spring has yet to be touched. Another cave has been explored to the length of 150 m (490 ft), and is said to be an ideal destination for cave divers in training. 1239: 22: 1003: 964: 924: 709: 621: 582: 524: 7708: 7740: 7698: 7730: 7719: 1419:

It is common practice for cave divers in Florida to joint a main line with a secondary line using a jump reel when exploring side passages, in order to maintain a continuous guideline to the surface.
