After ten months of planning and a week of intensive aquanaut training, the four of us plunged in at the Pinnacle not to return for 10 days. Our first order of business was to check in with Thor and Byron from the Gazebo. After listening to the diver recall alarm it was clear we had arrived. We could now enjoy the luxury of more than six hours of bottom time from 50 to 95 feet. We swam the travel lines to our deepest site at 95 feet and collected the seaweed specimens we will be using in our first of many exciting experiments. My buddy Julie and I spent the day sorting through seaweed samples, and building experimental units to be placed out in the grooves of the surrounding reef. We finished setting up the experiment by having Linda and Laura place fertilizer spikes in diffusers on half of our treatments. Day 2 found at least some of us right back out at the Pinnacle again. We spent three hours between 80 and 95 feet documenting the distribution of reef biota and setting up experiments on the dispersal and accumulation of fragments of a brown seaweed, Dictyota. It would have taken us an entire day if we were not saturated and diving from the surface. The current was in our face the whole trip out to the site. Even though we had to huff an puff to get us and all our gear out to the site, we just topped off our tanks at the underwater “fill” station located at the Pinnacle Way Station when we checked in with one of our two fantastic Aquarius specialists: Thor. I spent the afternoon with Julie and our honorary aquanaut PAM. PAM is a underwater fluorometer that we are using to measure photosynthesis underwater. By using Aquarius as our base I am able to make continuous measurements of photosynthesis on the seaweeds growing on Florida's coral reefs. This work will hopefully give us insight into why seaweed is thriving in this ecosystem. Evening came; the sun went down and photosynthesis would have to wait until tomorrow. Julie and I staged into the wet porch and devoured all the food that got in our way.
