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 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.

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.

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.

Holocene-aged coral samples from the south Florida region were extensively characterized to create a new database of verified sea-level data. The samples were originally collected using coral-reef coring or other geologic sampling methods and were obtained by various researchers from published studies spanning the interval of 1977 to 2017. Many of these samples are presently stored in the U.S. Geological Survey (USGS) Core Archive at the St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (https://doi.org/10.5066/F7319TR3). USGS staff compiled all relevant information from publications pertaining to each sample and then, if the samples were available in the USGS Core Archive, researchers performed visual analyses to characterize the taphonomic condition and to determine if samples were in situ (growth position). Samples were then assigned a rank (from 0-3, with 0 being the highest rank) to indicate their quality and reliability for use as sea-level indicators based on a combination of the information from the publications and the results of the analyses. This research is a part of the USGS Coral Reef Ecosystem Studies Project (https://coastal.er.usgs.gov/crest/).

This data release compiles radiometric data, photographs, and descriptive collection information (location, elevation, etc.) for late Holocene sub-fossil Acropora palmata and A. cervicornis coral samples collected from the coral reefs of Dry Tortugas National Park, Florida (DRTO) from 2015 to 2023. The samples were collected under scientific research permits from the U.S. National Park Service and all samples are currently recorded in the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center’s (USGS SPCMSC) Geologic Core and Sample Database (Williams and others, 2013) and archived at the center’s Core Archive.
