Bodega Canyon
A total of 14,271 m² of seafloor was classified during the 4 completed dives. The original two- character-code habitat types were aggregated into three general categories for this analysis: the ‘hard’ category included ridge, boulder, cobble and flat rock in various proportions; ‘mixed’ comprised one of the ‘hard’ classifications combined with mud or sand; and ‘sediment’ was represented by mud and sand or a combination of the two. The overall area surveyed by the AUV was approximately 90% sediment substrate.

Cape Canaveral North
Multiple dives, on August 7th and August 9th 2009, surveyed the ‘Cape Canaveral North' site using the Johnson Sea Link submersible.

Cape Canaveral Shallow
This site is composed of a southern part which contains three adjacent mounds, called Triceratops (Area III), separated from each other by about 500 m. Five JSL dives were made here in Aug 2009 and one Jason ROV dive was conducted here in Nov 2010. S. Brooke also conducted two JSL dives at this location in 2005. The three mounds are Lophelia pertusa bioherms surrounded by coral rubble and coarse sand substrata. The central mound is the largest, reaching a depth of just under 400 m, and the smallest mound is to the east. All three mounds exhibit rugged topography and are capped by extensive fields of living L. pertusa. Diversity of other corals (including Madrepora oculata and Enallopsammia profunda), sponges, and other sessile fauna is quite high on these mounds.

Cape Canaveral South
Multiple research cruises, beginning in 2005 and again in 2009, surveyed the ‘Cape Canaveral South' site using the Johnson Sea Link submersible. In 2010, a cruise surveyed the site using the Jason 2 ROV.

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.

Channel Islands National Marine Sanctuary
Channel Islands National Marine Sanctuary is an area of national significance because of its exceptional natural beauty and resources. It encompasses approximately 1,470 square miles (or 1,110 square nautical miles) of water surrounding Anacapa, Santa Cruz, Santa Rosa, San Miguel and Santa Barbara Islands, extending from mean high tide to six nautical miles offshore around each of the five islands. The sanctuary's primary goal is the protection of the natural and cultural resources contained within its boundaries.

Cordell Bank
While the continental slope and shelf region targeted by this survey is well known to fishers and mariners, in situ observations are rare owing to the difficulty posed by the elements, depth, and distance from shore. This first glimpse of the continental slope region of CBNMS revealed some expected as well as some unexpected findings.

Florida Straits Site
The survey on November 16, 2005 (Brooke et al.) used the R/V Seward Johnson deploying the Johnson Sea Link I Submersible supporting the Ocean Exploration 2005 program. The survey on May 29, 2007 (Messing et al.) used the R/V Seward Johnson deploying the Johnson Sea Link II Submersible supporting the Ocean Exploration Deep Coral Expedition.

Grays Canyon
Images of the seafloor were collected using two 5 Megapixel,12 bit dynamic range Prosilica GigE cameras. One camera was mounted to look directly downward and the second camera was angled forward at 30°. Lighting was provided by a strobe synced with the cameras. Two downward parallel lasers were used to estimate the sizes of organisms in photographs.
