Topic: Using underwater landscape mosaics in analyzing benthic communities

Abstract:

 

Between September 2008 and May 2010, underwater landscape mosaics were used to document and track the fate of an inshore patch reef before and after a catastrophic cold-water anomaly in January 2010. Comprehensive analysis of the benthic community showed mortality in 28%, 51%, and 36% of stony corals, gorgonians, and sponges, respectively, following the cold-water anomaly. Archived mosaics showed that bleaching the summer prior to the cold stress predisposed both corals and octocorals to mortality following the January event. Previous studies captured the fate of only scleractinian corals following this devastating event, thereby underestimating the magnitude of total reef-decline. This study suggests that all members of sessile benthic communities are susceptible to environmental disturbance. Providing an unparalleled visual record of reefal change, underwater mosaics support scientific understanding and public awareness of modern reef threats at a previously unattainable scale.
