Alert Diver Issue: Q1 2017
Caissons, Compressed-Air Work and Deep Tunneling
Do you know how underground tunnels are made? The working spaces, or caissons, are pressurized with compress air. But in the 19th century, many laborers had an unexplained illness after returning to atmospheric pressure.
Conch
Conch snails are remarkable creatures with a set of eyes, a nose (sort of), a mouth and one foot. And because they’re slow, conches are commonly picked up and are a considered a delicacy in some regions.

Differentiating Coral Bleaching and Coral Mortality
Corals bleach, or turn white, when their symbiotic algae are expelled from the corals’ tissues due to stressors such as excessively warm water. Bleached corals can and do recover when favorable conditions resume.
Flying After Pool Diving
DAN medics and researchers answer your questions about dive medicine.
