Details
Data consists of date, , temperature and predicted anomaly for two years of data.
Source
Data sets are
selected from the 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
).
Series elliot_yr2 records one winter (including the most positive
).
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 are also derived
from the local instrumental data. Temp is the predicted
for the summer interval of
Year1 and Temp2 is the predicted
for the winter interval of Year2.
