The oxygen levels are entirely influenced by these two factors and its crazy to think about how something we can't see impacts the system on such a tremendous level. The influence of night time and the tide affects what fish we see and captured in our seine net. One thing I noticed was when it was high tide there were more places the schools of fish could go to in order to avoid the big predators like ladyfish. Night time brought about more light sensitive fish and some of us used that to our advantage to get bait for fishing.:)
Two days later we were exploring the beaches of the area with Dr. Hackney and that was a blast. It was a treat to be with him because he really knows so much about coastlines and how they work. We discussed the natural vs unnatural inlets, the dune systems with there resilient vegetation, and how sediment is deposited along coastlines. I found it fascinating to learn about the differences between natural and unnatural jetties. Also I loved getting to see the rare coquina rocks and how they serve as a unique rocky intertidal habitat.
