In accordance with SO #3423 - The Gulf of America and SO #3424 - Mount McKinley and Landmarks Honoring the Alaskan People, new USGS data releases specific to those named places will utilize the new name Gulf of America and the restored name Mount McKinley. Per USGS practice, historical data will retain the name of the geographic features as they were known at the time the data were originally released.
Data Release
The Absolute and Relative Composition of Holocene Reef Cores From the Florida Keys Reef Tract
By Lauren T. Toth and Anastasios Stathakopoulos
USGS, St. Petersburg, Florida
Summary
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). Paleodepths of the same depths in the cores were estimated 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 Toth and others, 2019 (in preparation). This research is a part of the U.S. Geological Survey (USGS) Coral Reef Ecosystem Studies Project.
