Project Description

A major concern for the State of Florida is the impact of the Deepwater Horizon oil spill on coral-reef and other hardbottom communities of the Florida shelves. We propose to test both the toxicity and the sublethal effects of crude oil and dispersants on organisms that are amenable to experimental manipulation and representative of the reef community. Test organisms are reef-dwelling benthic foraminifer Amphistegina gibbosa and Archaias angulatus. These taxa host symbiotic algae, calcify and are abundant along most of the Florida coastline.
