Columbia Shallows

Columbia Shallows, Cozumel, Mexico			N 20° 19.0' W 87° 1.0'
Dive Number 169		Buddy Neva, Jay	Surface temp 25°C	Starting pressure 3000psi
Depth 42ft	Visibility excellent	Time 54m	Water temp 27°C	Ending pressure 1600psi
Notes:	Neva and I arrived in Cozumel and I had planned on doing as much snorkelling as she liked, but when she said she'd rather take her open water course, I was glad to go along! She spent much of the day on the 8th watching videos and doing knowledge reviews. After a pool session in the morning, we went out for her first basic open water dive. She completed a quick skills test, and then we went off to explore the reef. We saw some big lobsters, a big crab, and the biggest parrotfist I have ever seen (a midnight parrotfish). We're still working on indicating approval with something other than the thumbs up signal to ascend.
