basis: The higher skeletal d18O value reflects the high d180 value of the Bay water itself (Lloyd, 1964; Swart et al., 1989), which is enriched in d18O as a result of evaporation and the input of 1so enriched freshwater from the Everglades (Meyers et al., 1993). Salinity values are the highest during the summer, as a result of evaporation, and lower during the winter when the Bay becomes dominated by water from the Gulf of Mexico and the Florida Reef Tract. These changes in salinity should be manifested in the 6180 of the coral, but as the maximum enrichment in the water occurs during the warmest portion of the year (the summer), the temperature and salinity effects tend to counteract each other, thereby reducing the observed range of oxygen isotopic variation seen in the coral.

integrationTimeBasis: In South Florida, the dense band forms in the late summer, but it is generally thought that there is as much as a � two month variation in timing. By counting the number of bands in a coral, the age can be assessed. Errors in age interpretation arise when dense bands are indistinct or when so-called "stress bands", resulting from events such as temperature extremes, occur. Generally speaking, a year in which a stress band forms may actually contain two dense bands or a thicker dense band which is a combination of the stress and normal dense band. Although it is possible to misinterpret a stress band as an annual band, the annual bands can be recognized by their regular spacing. Therefore, density changes can still provide a clear annual chronology.
