Torricellian chamber
From Wikipedia, the free encyclopedia
In cave diving, a Torricellian chamber is a cave chamber full of water at less than atmospheric pressure. It happens when the water level drops and there is no way for air to get into the chamber. In theory it could risk decompression sickness, similarly to flying after diving. In a Torricellian chamber the diver's depth gauge is unlikely to show the truth, as all or most diver's depth gauges are not designed to show depths less than zero.
It is named after Evangelista Torricelli; the name compares the chamber to a liquid-based barometer.
