Thread: Argon, the Superior Dry Suit Inflation Gas? by Dr. Claudia Sotis

    After that study, I am more interested in that aerogel undersuit. That's 2-3.5x better than the commercial one.

    There is another study which you did not mention and which supports your initial position.


    Extrem Physiol Med. 2013; 2: 17.

    Argon used as dry suit insulation gas for cold-water diving

    Xavier CE Vrijdag, Pieter-Jan AM van Ooij, and Robert A van Hulst



    http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3710141/

    Human subjects diving in cold water (13oC) for 1 hour in a shell suit + undergarment, per the Nuckolls study, in which the insulation gas might be expected to exert a greater influence on insulation (as David pointed out). Suits flushed with inflation gas (argon or air) according to Risberg protocol (x3). Core temperature measured with an ingestible sensor and subjective thermal comfort recorded at end of dive (divers blinded to inflation gas). No difference between the groups in either core temperature or subjective comfort.

    My personal observation is argon does help. 13C and 1 hour dive is too warm to bother with argon. Where it matters is 0-4C temperatures with 1-3 hour dive times. You get the chills ( start to feel cold) much later with argon.

    Never heard someone from finland complain about cold =)


    Interesting reading btw

    iv dived Narvik mid november , quick slash in my dry bag on my last stop worked ok , cant say much on the argon as iv never used it ,

    id never carry a cylinder i cant breath from at some point in my dive , i norm have 50/60% nitrox in my suit feed , and a 2nd set of mits in my pocket
