Diving technology • SCUBA (Self Contained Underwater Breathing Apparatus) • System used to “breathe underwater” • Jacques Cousteau and Emile Gagnan • 1943
Diving technology • Rebreather • recycle the breathing gas • Freeflowing • surface supply diving • large high flow • Inefficent • Surface controlled • Demand regulator • Lowers air pressure in tube • Gives air in increments • First version created in 1838
Diving Technology • Pressure Gauge • Air pressure • Air left • BCD • Buoyancy Compensator Device • Makes diving eaisier
Types of Diving • Surface supplied diving • Supplied from the surface • Limited depth • Support platform • Mixed-gas diving • Avoid nitrogen narcosis • Heliox (deep) • NOT Nitrox
