Abstract: In 2010, the NOAA Deep-Sea Coral Research and Technology Program (DSCRTP) initiated a three- year study to advance our understanding of Deep-sea Corals (DSC) off the west coast of the U.S. During the first year of this study, a coast-wide survey of the distribution and abundance of DSC from Washington to southern California was conducted during three legs of a cruise aboard the NOAA ship McArthur II using the Kraken 2 remotely operated vehicle (ROV) operated by the University of Connecticut and the SeaBED autonomous underwater vehicle (AUV) operated by Northwest Fisheries Science Center and collaborators. The goals of this project were: (1) to characterize the distribution and abundance of DSC on Piggy Bank; (2) to understand factors (e.g. depth, substratum type) that influence their distribution and to assess the condition of DSC assemblages in relation to potential anthropogenic or environmental disturbances; (3) to evaluate the function of DSC as fish and invertebrate habitat.
