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.

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.
