Sr/Ca and linear extension data for a modern Orbicella faveolata coral from Marquesas Keys, Florida, USA

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-07-12T00:00:00Z
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.
