Blue Holes Exploration Extreme Underwater Cave Diving Exploring the World's Deepest Blue Hole
A team of divers plunge in to explore the mysterious blue holes of the Bahamas. It is believed that these underwater time capsules formed during the last ice age, the salt water is trapped without oxygen under fresh water in these deep underwater caves. Every dive into these unexplored caves is an exhilarating and dangerous endeavor with the divers grateful to come out of each dive alive. The divers never know what they are going to run into, they may even find colleagues from the past who never made it out. These time capsules hold stories of the past and climate changes throughout the years of Earth’s past. Because of the lack of oxygen fossils are conserved intact at the bottom of these gorgeous underwater palaces. As we presently experience climate changes due to global warming and the sort, explorers and scientists understand the importance of investigating these story telling historical treasures. The team removes a piece of a stalagmite from a cave that is then cut down the middle with a diamond cutter. This stalagmite can be dated and studied for clues about climate changes throughout Earth’s history much like tree-ring dating, take a look at what they believe to discover from this stalagmite. As ice glaciers melt and rising sea levels become a threat, the existing blue holes are expected to become flooded with water allowing oxygen to enter the depths of the caves. This means that existing fossils would immediately begin to decay destroying the precious and unexplored historical information contained within.
