Entity_Type_Definition:
These files contain attribute information for data describing the growth of corals in the Orbicella annularis species complex, which were collected from five study sites in the Florida Keys. Data include coral identification numbers, site where they were grown, fate of each colony during the study, original surface area of live tissue, time interval, calcification rate per day per colony, ending surface area of live tissue, and accumulative percent-tissue loss since deployment. To view the data in a tab-delimited format arranged by column, please use the Excel spreadsheet.
