The following outstanding 2 hour video shows the amazing biodiversity of the marine life in the Andaman Sea (in the northeast Indian Ocean). Produced by Nick Hope at Bubble Vision, he again amazes us while introducing us to many rarely seen marine species the way they should be met, in their home under the sea.

“In the deepest, darkest parts of the oceans are ecosystems with more diversity than a tropical rainforest. Taking us on a voyage into the ocean — from the deepest trenches to the remains of Titanic — marine biologist David Gallo explores the wonder and beauty of marine life.

So I should probably begin with part 1…. Back in 1960, January 23rd to be precise, the first ever deep submersible dive occurred by two oceanographers, Don Walsh and Jacques Picard. Using the Bathyscaphe Trieste (above) they reached a depth of 10,911 m (35,797 ft) at the Challenger Deep section of the Mariana Trench, the deepest part of the ocean (11 km or about 7 miles deep). This so far, is still the only time this depth has ever been reached in the ocean by humans with it taking the Trieste five hours to reach the bottom and only being allowed 20 minutes at this depth due to the constraints of technology at the time.

Alvin, the legendary research sub built by WHOI in 1964 and who allowed researchers to discover hydrothermal vent communities in 1977, is getting a major overhaul. Alvin allows researchers to conduct biological, chemical, geochemical, geological and geophysical studies while making 150 to 200 dives a year. Currently it can only reach depths of 4,500 meters (2.8 miles) and was planned for retirement until recently…
This is a very cool idea that provides divers with the opportunity to contribute to marine conservation simply by sharing their diving experiences.
earthdive is a revolutionary new concept in ‘citizen science’ and a global research project for millions of recreational scuba divers who can help preserve the health and diversity of our oceans. Continue reading →
