Ah! Pass the reg, bro!

Effects are sometimes felt
around 90-100’ whilst breathing
oxygen and nitrogen (normal
compressed air). The deeper you
dive, the more ‘stoned’ you get.
at 115’ I felt like I was on
laughing gas.

Tri-mix is used to combat narcosis
in deep open-circuit SCUBA diving.
Tri-mix consists of oxygen and nitrogen and I think helium (Fishboy is not looking at Wikianything just remembering the salad days of commercial diving up
here in the San Juans).

The idea is to lessen the amount of nitrogen which is heavy and inert and which dissolves into solution (i.e., blood) for some reason this makes you feel stoned under pressure. I can’t remember why.

Decreased nitrogen levels are
safer for deep diving anyway
since the body doesn’t metabolize it (O2) or exhale it (CO2) it just sits like a demon in you ready to
expand when you ascend and cause all kinds of hell (aka: The Bends)
if you don’t respect your diving
computer and its clever algorithms
or your dive tables if you couldn’t
afford a computer.

Nautilus live deep. Up to 500m
and ascend nocturnally to feed
but are very sensitive to light
so you’d have to dive deep to
goose one. And even on Tri-mix
you’d probably be giggling from
a touch of narcosis.

(I had to look up the part about
how deep N. pompilius lives. I
knew it was deep, but jeez).
