The wind is from the East at about 10 knots.  The surf is about 3 ft, but there are a few 5 ft breakers, too.  I enter in front of Tower 19 and head out at 100 degrees. Along the way I encounter a small Green Sea Turtle, who does not see me coming.  He races away before I can even raise my camera.  I get to the staghorn coral and find a small Brittle Sea Star, then the camera goes dark.  I play with it, but cannot figure out what is 

wrong.  I notice that I cannot change the aperature.
I swim on looking for the mountainous coral next to the medieval coral racks.  I move North a bit 

and find some coral racks built of concrete blocks and the sampling station I'd seen earlier, but I have no idea where I am other than North and East of the staghorn coral.  I continue playing with the camer and discover that the switch on 

the strobe battery is on "Full" rather than TTL.  I switch it back and apparently fix the problem. What a relief.   I continue to the Eastern edge of the reef and then swim North along the ledge, where I find a Scamp who is interested in me and lets me get some good shots and a Blue Hamlet 

who is also accommodating.  Then I turn West to the beach at a large rock and come upon the medieval racks withon 50 yards of the ledge.  I don't initially see the mountainous corals, then I do.  I surface to see where I am.  I think 100 

degrees out from the Tower.  When I descend, though, I cannot find the mountainous coral or the medieval racks.
My second dive begins the same as the first, except the wind has died down a bit and the surf 

has diminished some.  I swim out to the staghorn coral and to the ledge.  On the way back, I once again find the medieval racks and the moutainous coral.  This time, I surface to check and find it is 240 degrees looking back at the Tower, which is lined up 1/3rd of the way in the 

house across the street.  I look for the scietific station and the concrete block racks, but I do not find those.  I also look for a rock or some other easily recognized feature in the staghorn coral, but find nothing.  Visibility is bad, only 5-10 feet.
