MIR Dive - Kamchatka - Edited tape

This recording is of hydrothermal vents and surrounding chemosynthetic life deep on the ocean floor. Hydrothermal vents are one of the greatest discoveries of the twentieth century. They are theorized to be the originators of life on earth. This recording was made by the MIR submersibles that travel with their mothership RV Akademik Mstislav Keldysh, an oceanographic research vessel. The submersibles can reach depths of 6000 meters (almost 20,000 feet).
