Cape Fear Lophelia Banks
The entire dive took place over a dense Lophelia pertusa reef made up of primarily dead L. pertusa boulders and rubble. Only about 5-10% of the coral observed was living. Cup corals were abundant on the dead L. pertusa, while sponges and soft corals were rare. The most common mobile invertebrates were Eumunida picta and brittle stars. A single Rochinia crassa was observed and collected. Flytrap anemones and basket stars were observed occasionally.

Cape Lookout
Several fish and invertebrate species were observed during this dive. The dive began on dense rubble with Helicolenus dactylopterus, Laemonema spp., squid, and scorpaenids. Scorpaenids and Nezumia spp. were observed in rubble and hard coral habitats. The dominant coral in the area was Lophelia pertusa and was colonized by Echinus spp., numerous galatheids, and brittle stars.

West Palm Beach
This dive began to the south of the L. pertusa bioherm in rubble habitat before traversing over soft sediment and soft sediment with coral rubble and attached fauna. The first coral bioherm supported a mixed habitat of sponges and soft coral attached to coral rubble and hard coral habitat with attached fauna.

St Augustine
The St. Augustine lithoherm was composed primarily of a dead Lophelia pertusa rubble matrix on a carbonate rock substrate. Additionally, this site is a carbonate substrate lithoherm with rock slabs and outcrops covered in consolidated and unconsolidated coral rubble.

St Lucie Bump
The habitat of interest at St. Lucie Bump consisted of low to high relief coral mounds comprised of 99% dead Lophelia pertusa matrix with occasional live tips.

Savannah Banks
Very few fish were observed on this dive and were represented by very few individuals. The most common fish was Laemonema melanurum in all habitats observed. A few Nezumia spp. and squalid sharks were observed on mound. Fenestraja plutonia was observed on the soft substrate rubble mix. In the soft substrate rubble mix Phykalleia spp. was abundant in patches. Mound substrate of rock ledge and rubble was covered with abundant mixed fauna. Hard corals were represented by individuals of Lophelia pertusa, Madrepora oculata, Enallopsammia profunda, and numerous cup corals. Gorgonians were abundant but too small to be properly identified.

Stetson Banks
This dive transected a large portion of off-mound habitat and some on-mound habitat in the end. The low profile, off mound habitat had less than 10% live Lophelia pertusa coverage. A few species were seen in the off-mound area. The most common fish species was Laemonema barbatulum, and the most common invertebrate was Plumarella sp. (both on- and off-mound). Urchins and anemones were common. Galatheids were not present off-mound. In the last 30 minutes of the dive, the sub transected the top of a mound where L.pertusa was of higher relief and a greater percentage was alive (>25%). Galatheid crabs, brissingid sea stars, and sponges were common on top of the mound. Other fish species observed included Conger oceanicus, Nezumia spp., Beryx decadactylus, and a few scorpaenids. Sessile invertebrates observed included barrel sponges, glass sponges, Madrepora oculata, and a few gorgonians.
