Double Keyhole Springs 11/11/18


Dr. Garey and Bobby dove Doublekey Hole springs this past Sunday in hopes of reaching the “big room” about 1350’ into the cave. We are hoping to study the saltwater/freshwater interface in this room because we believe it creates the prefect redoxocline for chemolithoautotrophic bacteria. Unfortunately, due to a strong current, they weren’t able to make it all the way back. Dr. Garey and Bobby were happy to get back in the water after a a couple of months of no diving, however, and were still able to collect some samples for iron chemistry analysis. It was a beautiful day to be out on the water, and the group even got to witness a pelican and a dolphin fishing from the same school of mullet on their ride back in! We will be back soon, and will hopefully get to reach the big room next time.

A big thank you to our undergraduate Kim for snapping some great shots of the day!
