- I just saw a video made by some cave divers down in Acumel (sp?), in which
- they had to penetrate a large H2S layer to find the opening of a cave in a
- cenote. There was a lot of decaying vegetation laying around the foggy layer
- of H2S and the cloud litterly swallowed the beams of 50 and 200 watt lights
- the divers were using.
-
- Am I correct in assuming that divers are likely to encounter H2S only in areas
- where there's lots of decaying vegetation in undisturbed fresh water?
-
- Perhaps some net.divers who've seen episodes of the old "Undersea World of
- Jacques Cousteau" will remember when Cousteau and friends dove in the crater
- of a dormant volcano and ended up penetrating a layer of H2S. They complained
- about stinging in their eyes. Are H2S vapors an irritant, or was that perhaps
- H2SO4 vapors?
