I am interested in techniques for doing deco stops in open ocean. What do people do if you need to decompress in open ocean when there is a 1 m (3 foot) swell running ? It seems a 3 m stop would have a fairly rapid 30% change in pressure which seems like it might not be a good idea! I would guess that a solution might be to do the stops deeper (say 5m) and make them slightly longer, but really you should use specially calculated tables for this. I have not done any planned deco diving, but nearly always do a safety stop at 5 m. Holding even a 5 m safety stop in a reasonable swell (possibly with a current as well) is quite difficult. Typically for a no-deco dive to 40 m (130 feet), the shop I dive with will require a 3 minute stop at 10 m and a 5 minute stop at 5 m as safety stops. cheers, David. ______________________________________________________________________________ David Giddy, | Voice: +61 3 253 6388 Telecom Research Laboratories, | Fax: +61 3 253 6144 P.O.
