North Atlantic Mollusc IsotopesEntry ID: NOAA_NCDC_PALEO_95-018
Abstract: I. "Acal2" is calibration data for same period as stable isotope records and
includes (from L to R) : 1) the date (based on 8-month (May-Dec) growth year
and centered at mid-month); 2) mean monthly T C (based on ~daily BT records w/
linear interpolated gaps); 3) mean monthly Salinity (based on ~weekly BS
records w/ linear interpolated gaps); 4) "monthly" shell d18O data (based on
linear ... seasonal shell growth assumption); 5) estimated monthly d18O-water
based on salinity and Fairbanks'  relationship for Gulf of Maine; 6)
"monthly" shell d18O minus est. monthly d18O-water.
II. "Tmon" are all the mean monthly T & S records for 1956-1971 from the
Nantucket Lightship and includes: 1) date (centered at mid-month); 2) mean
monthly BT C (based on ~daily BT records w/ linear interpolated gaps except
where gaps are too large (>1or 2 months); 3) mean monthly BS (based on ~weekly
BS records w/ linear interpolated gaps except where gaps are too large (>1or 2
III. "sampall" are raw shell d18O records and includes: 1) shell surface
position (cm); 2) raw shell d18O; and 3) sequential sample # (214 out of 219
original samples w 5 samples lost during analysis).
