Summary

New sub annual and mean annual Sr/Ca records from two species of massive coral, Orbicella faveolata (coral B3) and Siderastrea siderea (coral CG2), from the Dry Tortugas National Park, FL (DRTO). Both corals have well-constrained chronologies, with coral B3 ranging from 1893-2008 and coral CG2 ranging from 1837-2012. We combine these new records with published Sr/Ca data from three additional S. siderea coral colonies (DeLong et al., 2014) to generate a 278-year-long multi-species composite Sr/Ca-SST record from DRTO. This new record from a region sensitive to the Atlantic Multidecadal Oscillation (AMO) and Atlantic Meridional Overturning Circulation (AMOC) variations provides insight into the link between the two systems. Also included are new annual linear extension rates for each species. The coral samples and derived data were collected under the National Park Service Scientific Research and Collecting permits DRTO-2008-SCI-0015 and DRT0-2012-SCI-0001; accession numbers DRTO-241 and DRTO-353.

Map of the Dry Tortugas National Park (82°W, 24°N). The locations of coral cores are indicated on the map by yellow stars. A core was collected from the living Orbicella faveolata coral colony B3 at Pulaski Shoal in August 2008. The core from the living Siderastrea siderea colony CG2 was collected in March 2012 from Pulaski Shoal. Inset: Map of Florida (USA) with a box around the Dry Tortugas National Park.
