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.

Descriptive Core Logs, Core Photographs, Radiocarbon Ages, and Accretion Data from Holocene Reef Cores Collected Throughout the Florida Keys Reef Tract
By Lauren T. Toth, Anastasios Stathakopoulos, and Ilsa B. Kuffner
USGS, St. Petersburg, Florida
Summary
The USGS core archive (Reich and others, 2009; USGS Core Archive) houses an extensive collection of coral-reef cores that USGS researchers have collected from throughout the Florida Keys reef tract (FKRT; fig. 1). USGS scientists have compiled all available data on the 71 core records that recovered Holocene reef framework, including radiometric ages (radiocarbon and U-series), data on reef development (timing of reef initiation and senescence, reef accretion, and reef thickness), and metadata on the cores and collection sites. High-resolution core photographs and descriptive core logs of each of the cores were also produced. For further information regarding data collection and analysis methods refer to Toth and others, 2018. This research is a part of the U.S. Geological Survey (USGS) Coral Reef Ecosystem Studies Project (https://www.usgs.gov/centers/spcmsc/science/coral-reef-ecosystem-studies-crest).
