In particular, please look at the footage between 2:22 and 3:02. The little ones visiting here who saw this on DVD had a few questions, and I developed a couple of my own.
- Is there a possibility of encountering a vertical current, depending on conditions and topography?
- Could a freediver in trunks really lose enough buoyancy to keep them from regaining the surface?
- What depth would that be likely to become an issue?
- Is this a useful illustration of SWB?
Thanks for watching and thinking.
