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.

Summary
Massive corals are used as environmental recorders throughout the tropics and subtropics to study environmental variability during time periods preceding ocean-observing instrumentation. However, careful testing of paleoproxies is necessary to validate the environmental-proxy record throughout a range of conditions experienced by the recording organisms. As part of the USGS Coral Reef Ecosystems Studies project, we tested the hypothesis that the coral Siderastrea siderea faithfully records sea-surface temperature (SST) in the Sr/Ca record throughout the subtropical (Florida, USA) seasonal cycle along 350 km of reef tract. Coral samples were analyzed from thirty-nine corals growing in 3 to 4 m depth at Fowey Rocks (Biscayne National Park), Molasses Reef (Florida Keys National Marine Sanctuary, FKNMS), Sombrero Reef (FKNMS), and Pulaski Shoal (Dry Tortugas National Park). Temperatures were recorded with Onset® HOBO® Water Temp Pro V2 (U22-001) data loggers in duplicate at each site. Sr/Ca, Mg/Ca, calcification rate, and select underwater temperature data are provided here. The results of this experiment are interpreted in Kuffner and others (2017). A larger temperature dataset, including the data provided here, is found in another data release Kuffner (2016), and a larger calcification-rate dataset is interpreted in Kuffner and others (2013).

Figure 1. Location map showing the four locations where corals were monitored for growth on the Florida Keys outer reef tract and then sampled for geochemical analysis. Sites from west to east are Pulaski Shoal (24.69355°N 82.77280°W), Sombrero Reef (24.62687°N 81.10893°W), Molasses Reef (25.01047°N 80.37530°W), and Fowey Rocks (25.59047°N 80.09560°W). Inset shows location of the Florida Keys in relation to the state of Florida, U.S.A.
