Descriptive core logs, high-resolution images and derived data for Holocene reef cores collected from 1976 to 2017 along the Florida Keys reef tract

Metadata Updated: December 11, 2019

The USGS core archive (Reich and others, 2009; houses an extensive collection of coral-reef cores that USGS researchers have collected from throughout the Florida Keys reef tract (FKRT). 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 geospatial information. High-resolution core photographs and descriptive core logs for 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 (
