Multi-species Coral Sr/Ca Based Sea-Surface Temperature (SST) Reconstruction Data Using Orbicella faveolata and Siderastrea siderea from Dry Tortugas National Park, FL
This data release includes 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 (DTNP). We combine these new records with published Sr/Ca data from three additional S. siderea coral (DeLong et al., 2014) to generate a 278-year long multi-species stacked Sr/Ca-SST record from DRTO. |

Sr/Ca and linear extension data for five modern Orbicella faveolata colonies from Dry Tortugas National Park, Florida, USA
This data release includes new, sub-annual Strontium/Calcium (Sr/Ca) and annual linear extension rates covering a period between 1980 and 2012 for five colonies of the massive coral, Orbicella faveolata (O. faveolata). All five coral colonies were collected live by U.S. Geological Survey (USGS) scientists from the Dry Tortugas National Park (DTNP), Florida (FL) in August 2008 and May 2012. |

Sr/Ca and linear extension data for a modern Orbicella faveolata coral from Marquesas Keys, Florida, USA
This data release contains new subannual Strontium/Calcium (Sr/Ca) and annual linear extension records from a colony of the massive coral, Orbicella faveolata. The colony was collected live from the Marquesas Keys, Florida (FL) in August 1980 from core MK1. The coral Sr/Ca paleothermometer can provide a powerful proxy for centennial-scale sea-surface temperature (SST) variability in the Caribbean/Atlantic Ocean region. |

Data for evaluating the Sr/Ca temperature proxy with in-situ temperature in the western Atlantic coral Siderastrea siderea
Massive corals are used as environmental recorders throughout the tropics and subtropics to study environmental variability during time periods preceding ocean-observing instrumentation. However, careful testing of paleoproxies is necessary to validate the environmental-proxy record throughout a range of conditions experienced by the recording organisms. As part of the USGS Coral Reef Ecosystems Studies project (http://coastal.er.usgs.gov/crest/), we tested the hypothesis that the coral Siderastrea siderea ... |

Coral cores collected in Dry Tortugas National Park, Florida, U.S.A.: Photographs and X-rays
Cores from living coral colonies were collected from Dry Tortugas National Park, Florida, to obtain skeletal records of past coral growth and allow geochemical reconstruction of environmental variables during the corals’ centuries-long lifespans. The samples were collected as part of the U.S. Geological Survey (USGS) Coral Reef Ecosystems Studies project (http://coastal.er.usgs.gov/crest/) that provides science to assist resource managers tasked with the stewardship of coral reef resources. Three colonies ... |
