Made it through night one! John and Jeremy filmed corals feeding until after midnight. Brad and Karla collected zooplankton samples every three hours until dawn. Brad was still on the reef as the sun came up! Just as it was getting light, he described a flurry of activity where large fish were "schooling" smaller fish, and the result was a feeding frenzy.

The Habitat has now been located at Conch Reef for many years now, and there are some huge resident fish. Five to seven foot tarpon are not uncommon, along with really big permit. There are also many resident, large barracudas. Although menacing looking, these fish are content to passively watch our activities from a distance.

For the most part, all went well with our science. We are still working out a few bugs in the experimental protocol, but we captured some great video footage and other data. Water and electronics sometimes don't mix. One of our zooplankton pumps flooded and will have to be replaced tonight. Luckily, we have a great science team back ashore at mission control (led by Ken Sebens); they are already building a replacement.

After setting up corals for feeding studies later tonight, John and Jeremy swam out to an old study site where we are monitoring the growth rates of about 50 corals. After the coral identification numbers are located and cleaned (they get covered with algae and other encrusting organisms), we will return to photograph the corals later in the mission.

It's 5:00 pm, and our whole crew is starting to pull on their wet dive gear for another long night in the water.
