Details

Data consists of date, delta-18O, temperature and predicted anomaly for two years of data.

Source

Data sets are selected from the delta-18O record of a modern Mercenaria mercenaria shell collected live from Cedar Key in northern Florida and analyzed by Elliot et al. (2003). Series elliot_yr1 records one summer (including the most negative delta-18O). Series elliot_yr2 records one winter (including the most positive delta-18O).

Because the modern Mercenaria mercenaria shell by Elliot et al. (2003) is well dated and its in situ records of SST and salinity are available, the predicted delta-18O are also derived from the local instrumental data. Temp is the predicted delta-18O for the summer interval of Year1 and Temp2 is the predicted delta-18O for the winter interval of Year2.
