Olympic Coast NMS
In order to meet the needs for additional information on deep-sea corals (DSC), surveys of DSC ecosystems in the OCNMS were conducted utilizing a ROV and an AUV off the NOAA Ship McArthur II in June 2010. Both survey vehicles targeted known or suspected DSC sites both inside the current EFH conservation area known as 'Olympic 2'. Sampling also targeted adjacent areas that have been proposed as boundary expansions and/or have additional fishery restrictions.

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.

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.

Hidden Reef Cowcod Conservation Area
The Hidden Reef study site covers about 290 km² and is located within the Cowcod Conservation Area (CCA), which was closed to bottom-contact fishing gear by the Pacific Fishery Management Council in 2001. This area also was protected in 2006 under Essential Fish Habitat (EFH) regulations (NMFS 2005). Prior to CCA and EFH designation, this area was a longtime focus of intense fishing effort in southern CA.

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.

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.

Gulf of the Farallones
Rittenburg Bank had the highest density of sponges in comparison to Cochrane Bank and Farallon Escarpment. Habitat at Rittenburg Bank is suitable for corals and sponges, with 10.1 % being rugose, hard substrate. Cochrane Bank has long-lived coral Antipathes dendrochristos, a species previously thought to be endemic to Southern California (Love et al. 2007), but now discovered in GFNMS and believed to be at the northern extent of its range. The Farallon Escarpment, west of Cordell Bank, Cochrane Bank, and the Farallon Islands, differs significantly from adjacent areas of the continental slope.

Piggy Bank Seamount
The Piggy Bank seamount is located within the Channel Islands National Marine Sanctuary. It is designated as essential fish habitat (EFH) by NOAA Fisheries and the Pacific Fisheries Management Council and is within the Footprint Marine Reserve. This area is especially important because it represents extensive, deep, rocky habitats, which are uncommon within the Sanctuary, and is accessible from nearby ports and protected from adverse sea conditions.

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.

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.
