Self-Contained Underwater Breathing Apparatus

Self-Contained Underwater Breathing Apparatus. In words, it's a portable breathing device for free-swimming divers, consisting of a mouthpiece joined by hoses to one or two tanks of compressed air that are strapped on the back.

I don't know if anyone said this already, but it stands for Self-Contained Underwater Breathing Apparatus. Thank you for listening.

The word 'SCUBA' is an acronym for "Self Contained Underwater Breathing Apparatus", but it has become acceptable to refer to 'scuba equipment' or 'scuba apparatus'. The term SCUBA in common usage usually means open-circuit equipment in which gas (usually air) is breathed from a tank of compressed gas and then exhaled into the water, usually in the line of kit development started by Emile Gagnan and Jacques-Yves Cousteau. However, rebreathers (both semi-closed circuit and closed circuit) are also self-contained systems (as opposed to surface-supplied systems) and could be classed as SCUBA. The term SCUBA arose during World War II and originally referred to USA combat frogmen's oxygen rebreathers, developed by Dr. Christian Lambertsen for underwater warfare Submillimetre Common-User Bolometer Array, an instrument used on the James Clerk Maxwell Telescope SCUBA is sensitive to the thermal emission from interstellar dust. This emission is a tracer of star formation in other galaxies and gives astronomers clues to the presence, distance, and evolution history of galaxies other than our own. Within our own galaxy dust emission is associated with stellar nurserys and planet forming solar systems
