Spotted this Nurse Shark under the Big Rock and was able to get a few pictures without unduly disturbing the creature.
Spotted this Star Horseshoe worm on the knoll.
This was, however, one of the few dives on which I did not see anything new.
Dive Time was 145 minutes; RMV was 0.36 ft3/minute.
The first dive was longer than I had anticipated. I quickly changed tanks. The new tank showed 3560 psi, but had been sitting in the sun. Nonetheless, I was expecting a very long second dive. On the way out to the swim buoy, however, my Suunto showed only 598 psi in the tank. I was committed by that time, so I descended and swam out to the counter-weight and looked for a 20 ft hole.
the tank pressure reading got down below 100 psi and I decided to just call the dive. Even if I got more air, I wouldn't be comfortable not knowing how much and the gauge was apparently stuck on 100 psi. I had hoped it might start reading something in excess of 3000 psi, but it never did. So I got out and went back to the truck. I put my mechanical gauge on the tank and it showed over 3000 psi. I put the Suunto back on, and it then read 2530 psi, which sort of fits with me using 500 psi on the short dive.
Dive Time was 34 minutes; RMV was 0.26 ft3/minute, which is sort of surprising given the amount of swimming I did and against the current, as well. It suggests that I passed on what may well have been a record breaking dive for me.
