Maps, Tools & Applications

Access deep sea coral and sponge data: Digital Map allows for search, discovery, and download of the National Deep-Sea Corals and Sponges Database. All points are categorized and colored by common vernacular categories. Users can search by taxon, region, time, and depth. Data downloads can be initiated using the search parameters on the map and the on-screen geographic extent.

Data & Publications

A Pilot Survey of Deepwater Coral/Sponge Assemblages and their Susceptibility to Fishing/Harvest Impacts at the Olympic Coast National Marine Sanctuary (OCNMS): Cruise Report for NOAA Ship McARTHUR II Cruise AR-04-04 Leg 2

The offshore shelf and canyon habitats of the OCNMS (Fig. 1) are areas of high primary productivity and biodiversity that support extensive groundfish fisheries. Recent acoustic surveys conducted in these waters have indicated the presence of hard-bottom substrates believed to ...

An introduction to NOAA's National Database for Deep-Sea Corals and Sponges

NOAA's Deep Sea Coral Research and Technology Program (DSCRTP) is compiling a national database of the locations of deep-sea corals and sponges, beginning in U.S. waters. The DSCRTP will make this information accessible to resource managers, the scientific community, and ...

Application of the Coastal and Marine Ecological Classification Standard (CMECS) to Deep-Sea Benthic Surveys in the Northeast Pacific: Lessons from Field Tests in 2015

The Coastal and Marine Ecological Classification Standard (CMECS) is a comprehensive, standard terminology published in 2014. The standard is intended to unify habitat classification efforts, in order to allow for broader integration and comparison of data. The standard is well-developed, ...

Benthic Characterization of Deep-Water Habitat in the Newly Expanded Areas of Cordell Bank and Greater Farallones National Marine Sanctuaries

A large area of the seafloor off northern California lies within the US National Marine Sanctuary System, but very little of the habitat has been explored and even less is characterized using visual survey techniques, especially deep-water habitats. Benthic surveys ...

Characterization of deep coral and sponge communities in the Gulf of the Farallones National Marine Sanctuary: Rittenburg Bank, Cochrane Bank and the Farallon Escarpment

The purpose of the surveys was to groundtruth mapping data collected in 2011, and to characterize the seafloor biota, particularly corals and sponges, in order to support Essential Fish Habitat designations under Magnuson-Stevens Act (MSA) and other conservation and management ...

Cruise Report for Patterns in Deep-Sea Corals Expedition 2016: NOAA ship Shearwater SW-16-08

The 2016 Patterns in Deep-Sea Corals expedition set out aboard the NOAA Ship Shearwater in August to study the distribution, ecology, and health of deep-water (30-300 m) gorgonian corals in response to the 2015 El Niño event. The research team ...

Cruise Report for Patterns in Deep-Sea Corals Expedition: NOAA ship Bell M. Shimada SH-15-03

Less than 50% of the Channel Islands National Marine Sanctuary seafloor has been mapped using multibeam echosounders to produce habitat characterizations at a map resolution suitable for resource management. This is important because deep-sea coral and sponge communities are known ...
