Uk'37 SST's calculated using 2 different calibrations:
Sikes and Volkman [1993] calibration 9Uk'37= 0.0414T-0.156)  (designated S&V) 
and Prahl and Wakeham [1998] (Uk'37 = 0.034T+0.039) (designated P&W)
Data 1995 one sigma =1.0 °C Antarctic CRC/CSIRO Oceanography 
(Dr. E. Sikes' and Dr. J. Volkman's labs)

Foraminiferal SST's determined with Modern Analog Technique (MAT)
Using Southern Ocean core-top set, Data 1997, 
one sigma = 2 °C Antarctic CRC (Dr. W. Howard)
Age determined by interpolation between stage picks, one sigma N/A
