Chacal-Al, Riviera Maya, Mexico			N 20° 29', W 87° 13'
Dive Number 135		Buddy Jim	Surface temp 24°C	Starting pressure 3000psi
Depth 73ft	Visibility excellent	Time 55m	Water temp 26°C	Ending pressure 750psi
Notes:	For the afternoon dive from the resort, our leader was Sergio, and I was buddied with Jim Ryder, the Montana diver who I'd been paired with for yesterday's cenotes dives. Although five of us dove en masse, two ended their dive after about 30 minutes because of low air, and the remaining three of us stayed on the reef to enjoy a little more bottom time. I was pleased to see yellowtail damselfish (one of my favourite fish) on this dive, as well as large school of blue tang. The photos are of some of the tang, as well as a smooth trunkfish. So ends my diving for 2010!

Dive Number 134		Buddy Dan	Surface temp 24°C	Starting pressure 3000psi
Depth 42ft	Visibility excellent	Time 48m	Water temp 24°C	Ending pressure 1350psi
Notes:	For the second day, harbours in Cozumel were closed, so I joined the daily dives offered by Dressel Divers to the reefs offshore from the resort. This first dive was with Giorgia, who led four of us out of twelve total divers. Although the highlight of the dive was a set of three French angelfish, my photos are of a squid and a foureye butterflyfish. I managed to see a couple queen angels, a lobster, and two puffers that my dive buddies missed. We also saw a spotted drum.

Chak Mool, Riviera Maya, Mexico			N 20° 36', W 87° 12'
Dive Number 133		Buddy Jim Ryder	Surface temp 24°C	Starting pressure 2950psi
Depth 43ft	Visibility excellent	Time 41m	Water temp 23°C	Ending pressure 1750psi
Notes:	For some reason, the two Ottawa divers who formed part of our foursome for the first dive opted out of the second. Their loss: The return to Chak Mool was more beautiful, more convoluted, and featured a short stop in an air pocket that connected to the surface, from which the bottom of tree trunks could be seen that pierced into the top of the cavern. The salt/fresh-water halocline created a very mild thermocline as well, and it was unusual to dive in a place that got warmer as it got deeper. I'm grateful to Fernando for suggesting that I log cenotes dives while on vacation in the Yucatan.

Dive Number 132		Buddy Jim Ryder	Surface temp 24°C	Starting pressure 2950psi
Depth 43ft	Visibility excellent	Time 37m	Water temp 25°C	Ending pressure 1950psi
Notes:	I hooked up with the folks at Dressel Divers while on vacation at the Barcelo Maya Hotel for Brad and Karine's wedding. I had taken it under advisement that a dive of one of the cenotes was in order, as well as Cozumel. Normally, a diver would do Cozumel first (so that divemasters could ensure adequate buoyancy control for cavern diving), but with they allowed me to join an expedition to Chak Mool today instead. The first dive of the cenote was a simple one - we followed a line around a cave lit from a single opening that was within view at all times. The water was warm, and the experience was unique, although it was really just a primer for the second cenote.
