One World One Ocean takes a GoPro dive into the last underwater research lab in the world - Aquarius Reef Base, to visit National Geographic Explorer-in-Residence, Dr. Sylvia Earle. The three divers in this video include: Ocean explorer Fabien Cousteau, filmmaker Marc Ostrick, and tech and ocean journalist, Brian Lam. We were warmly greeted by Sylvia as we approached the habitat, which is located three miles off Key Largo, FL.

This could very well be the most beautiful bubble ring (also known as a toroidal vortex) ever recorded on film. This clip is from the award-winning IMAX classic, DOLPHINS by MacGillivray Freeman Films, founders of the One World One Ocean Campaign.

A toroidal vortex, also called a vortex ring, is a region of rotating fluid moving through the same or different fluid where the flow pattern takes on a toroidal (doughnut) shape. The movement of the fluid is about the poloidal or circular axis of the doughnut, in a twisting vortex motion. Examples of this phenomenon are a smoke ring or a microburst. Vortex rings were first mathematically analysed by the German physicist Hermann von Helmholtz, in his paper of 1867 On Integrals of the Hydrodynamical Equations which Express Vortex-motion Smoke rings have probably been observed since antiquity since they can easily be blown from the mouth.
