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).

TAG Atlantic vents 14,000' is an edited live action recording of hydrothermal vents and vent ecology at the TAG site deep on the North Atlantic 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. In this recording the ecology consists primarily of millions of shrimp. The recording was made by aid of the Mir submersibles, who typically dive in pairs, one of whom can be seen recording the vents and shrimp. The scene was probably recorded in 1991, two years after an underwater volcanic eruption at that site.
Deep sea sharks Bermuda 4,000' is an edited live action recording of two six-gill sharks attempting to get at bait that is inside a cage. The recording climaxes when two six-gill sharks fight mouth to mouth. The unedited version of this version can be seen in: Bermuda sub-dive roll 3; Emory Eugenie shark baiting. The recording is shot from the Mir 1 submersible as documented in: Deep Sea Sharks Bermuda 4,000, a produced version of the recording.

TAG Atlantic vents 14,000' was recorded deep in the Atlantic Ocean. The location and date information is documented in: TAG Atlantic Vents, an edited and produced version of this recording.
