I've been reading the thread of the rescue of the soccer team in Thailand, it has left me with a question. One of the posts mentions that a portion of the dive was at 90'. That got me thinking about what that even means:
1. As an Open Water diver, I instinctively understand the pressure exerted by the water above me. How does this translate in a sump or a cave?
2. What happens in an air space like the one the boys were trapped in? Is that air space at 1ATA or is it at the depth that the water level is at? What does that mean for a diver's deco obligation when getting out of the water and into that airspace?
Inquiring minds want to know.
