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.
