Acknowledgment of the USGS Coastal and Marine Geology Program, as a data source would be appreciated in products developed from these data, and such acknowledgment as is standard for citation and legal practices for data source is expected.
Data were obtained to test 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 a 350-km longitudinal gradient. These data will be used to improve quality control protocols for using Sr/Ca as a proxy for sea-surface temperatures and the inferences about past climate variability that are the product of these types of studies.
