West Coast Groundfish Bottom Trawl Survey Observations of Deep-sea Corals and Sponges
This dataset includes records of coral and sponge catch identified in trawl hauls made during the West Coast Groundfish Bottom Trawl Survey (WCGBTS). The WCGBTS is conducted at water depths ranging from 55 - 1,280 meters off the U.S. West Coast, including the States of Washington, Oregon, and California. The WCGBTS is conducted annually by NOAA Fisheries' Northwest Fisheries Science Center. These catch records are included in NOAA's Deep-Sea Coral Research and Technology Program (DSCRTP) National Database for Deep-sea Corals and Sponges.
NOAA DSCRTP compiles a national database of the known locations of deep-sea corals and sponges in U.S. territorial waters and beyond. Demersal and benthic fish occurrences that were recorded along with coral and sponge surveys are also included. The database is comprehensive, standardized, quality controlled, and networked to outside resources. The database schema accommodates both linear (trawls, transects) and point (samples, observations) data. The structure of the database is tailored to occurrence records of all the azooxanthellate corals, a subset of all corals, and all sponge species. Records shallower than 50 m are generally excluded in order to focus on predominantly deep-water species the mandate of the DSCRTP. The intention is to limit the overlap with light-dependent (and mostly shallow-water) corals.
