MICROSPHERE-BASED PASSIVE MATERIAL FOR LOW-TEMPERATURE DIVING SUITS
Navy divers and dive-qualified personnel are often required to operate in cold water. The threat of hypothermia and other health concerns limits the time a diver is allowed in the water. The neoprene wetsuit is the primary material used for protection in low temperature conditions. Small pockets of...

Navy divers and dive-qualified personnel are often required to operate in cold water. The threat of hypothermia and other health concerns limits the time a diver is allowed in the water.
