The Atlantic Ocean
The Atlantic is the second largest ocean on the planet. It is the resting place of the Titanic, home to the mysterious Bermuda Triangle and is the youngest of the Earth's great oceans. It reaches depths of 8,500 metres. Oceans investigates this influential body of water from a group of islands in its western reaches - the Bahamas.
Black Hole of Andros
The Black Hole found on the island of South Andros is a large isolated column, about 47m deep and formed by chemical erosion. Its depths replicate ocean conditions billions of years ago.
At about 18m there is a 1m dark purple layer of toxic bacteria containing high concentrations of hydrogen sulphide. This toxic layer looks so dark it resembles the hole's floor but is actually a boundary which separates oxygenated water from oxygen-free water below it. This oxygen-free water has similar properties to water found in the oceans 3.5 billion years ago.
|Importance:||The conditions found in the depths of this hole resemble those found in our oceans billions of years ago.|
|Dive category:||This is a low visibility dive with many hazards due to harmful toxic layers of water and low visibility.|
|Access:||This is a site of scientific interest and its conditions are unique because it's so rarely disturbed, for this reason, access is restricted.|
