Data Set Description: This is a subset of the Deep Sea Coral Research and Technology Program’s National Database. These records are coral and sponge annotations from still image transects. Still images were acquired with drop camera aboard the R/V Tiglax in 2016. The following localities were surveyed: Kiska; Buldir; Semichi; Semisopochnoi; Attu; Agattu; Amchitka; Hawadax Island; Ulak. Chris Rooper was the principal investigator and the person who identified the corals and sponges within the imagery. See the Citation: Bryan, D. R., M. Levine, and S. McDermott. 2018.
