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.

This data release compiles descriptive information (location, water depth, etc.) and radiometric ages from corals collected through the Southeast Florida Continental Reef Tract (SFCRT; Figure 1). The database includes data from studies published between 1977 and 2015 as well as previously unpublished data. The samples were originally collected using coral-reef coring or other geologic sampling methods. Many of the 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). This research is a part of the U.S. Geological Survey (USGS) Coral Reef Ecosystem Studies Project (https://coastal.er.usgs.gov/crest/).

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 data release compiles Uranium-series (U-series) data and descriptive collection information (such as sample/core identifier, location, elevation, etc.) for late Pleistocene coral subsamples from coral reef cores previously collected throughout the Florida Keys (Florida) by U.S. Geological Survey (USGS) researchers. The samples were collected under scientific research permits from the Florida Keys National Marine Sanctuary (FKNMS) and U.S. National Park Service (NPS) and all samples are currently recorded in the St. Petersburg Coastal and Marine Science Center’s (SPCMSC) Geologic Core and Sample Database (Williams and others, 2013) and archived at the center’'s Core Laboratory Archive.

This data release provides a summary of the absolute percent composition of all recovered material and relative percent composition of coral taxa in the Holocene-aged intervals of 61 coral-reef cores collected throughout the Florida Keys reef tract (FKRT) housed in the USGS Core Archive in St. Petersburg, FL (Estimated ages for distinct depths within each core are also provided; those ages were either measured by radiometric dating of coral samples at those depths or estimated by linear interpolation between measured ages. A complete dataset of all measured ages in the cores is available at https://doi.org/10.5066/F7NV9HJX (Toth and others, 2018).Estimated paleodepths of the equivalent depths observed in the coral cores acquired from 1976 to 2017 were determined by extracting the relative sea level (RSL) for each age in the cores from the model of Holocene RSL in south Florida developed by Khan and others (2017). For further information regarding data collection and analysis methods refer to the associated journal article (Toth and others, 2019).

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).
