Bobby and Dr. Garey made their first post-hurricane Irma dive on Tuesday October 3rd. The flow was as strong as we have encountered and it took a major effort to get in, especially with all of the sampling gear and instrumentation we had to carry. Luckily there is a thick rope tied of inside the cave along the right side as you enter, which helps when you can't simply swim in. Once we got in to where the cave opens up, the current drops off and we proceeded to our instrument station about 300 ft in at a depth of 80 ft. We swapped out the ADV and Hydrolab and went to our 90 ft deep sampling station about 20 feet further in the cave. There we collected water, sediment and biofilm samples. Total dive time was about an hour. Then the students pulled another long night analyzing all the samples. It is a lot of work on dive day!
