New paper on the thermal characteristics of Argon

by Erik Dasque

This new paper seems to do a better job at establishing the usefulness of Argon in dry suit inflation for cold water diving than a prior document did.

It’s worth reading completely but here is the conclusion: “This investigation has demonstrated that significant improvements in drysuit thermal protection can be achieved when using argon instead of air as a drysuit inflation gas. It should be noted however that these improvements can only be achieved by carefully and repeatedly purging (a minimum of 6 purge cycles) with pure argon prior to water entry”
