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.

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.

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 faithfully records sea-surface temperature (SST) in the Sr/Ca record throughout the subtropical (Florida, USA) seasonal cycle along 350 km of reef tract. The datasets included in this data release are comprised of data collected between 2009 and 2013. Coral samples were analyzed from thirty-nine corals growing in 3- to 4-meter water depths at Fowey Rocks (Biscayne National Park), Molasses Reef (Florida Keys National Marine Sanctuary, FKNMS), Sombrero Reef (FKNMS), and Pulaski Shoal (Dry Tortugas National Park). Temperatures were recorded with Onset® HOBO® Water Temp Pro V2 (U22-001) data loggers in duplicate at each site. Sr/Ca, Mg/Ca, calcification rate, and select underwater temperature data are provided here. The results of this experiment are interpreted in Kuffner and others (2017). A larger temperature dataset, including the data provided here, is found in another data release Kuffner (2016), and a larger calcification-rate dataset is interpreted in Kuffner and others (2013).

This data release contains new, 40–70-year long subannual strontium-to-calcium ratio (Sr/Ca) records and linear extension measurements from five mid-to-late Holocene, Orbicella faveolata corals from the Dry Tortugas National Park (DT) and Marquesas Keys (MK), Florida (FL). U.S. Geological Survey (USGS) researchers used these Sr/Ca data to calculate sea-surface temperature (SST) using the Sr/Ca-SST equation from Flannery and others (2018). The data release also provides and stable oxygen isotope snapshots from two of the mid-Holocene corals. These data provide a proof-of-concept for the value coral-based paleoclimate records in the subtropical western Atlantic during the Holocene. Detailed information regarding data collection and processing methods can be found in Jacobs and others (2025).

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.
