We got to see a prominent karst feature today. The Blue Hole on the island is one of the largest karst features.
The water was incredibly murky, but the highlight of the dive was going down toward the bottom toward a boundary of cold water. I reached the refreshing, cool and clear water. At 10 feet down I could see a cave entrance that connects the Blue Hole to the ocean. After a few leaks with my sampling bottles I got some readings to study later.
After collecting samples for my research, we saw a little stingray and a huge parrot fish. It was a chance to relax and pretend to be a biologist.
