Sachs and Sachse 2008, GCA , 72:793-806. Conclusions of the paper are about moisture balance (P-E) in the tropical Pacific.
Sachs and Sachse 2008, GCA , 72:793-806; "dD values of lipids...were closely correlated with salinity, owing to a decrease in D/H fractionation between lipids and source water as salinity increases. TLE dD values can therefore be used as a salinity indicator in hypersaline evnrionments such as those at Christmas Island".
fraction of modern 14C activity uncertainty
210Pb, 239+240Pu or 137Cs activity uncertainty
Y if supported 210Pb activity, N if unsupported 210Pb activity
model used to convert 210Pb activity to age (e.g., constant rate of supply)
years before 1950 (calibrated age, or ages that dont need calibration)
ageUncertainty (85% atmosphere, 15% marine model)
the only uncertainty information I have been able to find is as follows "The average standard deviation (sigma) of all measured samples was 3.8?" from Sachse and Sachs (2008) GCA, 72:793-806 (this paper was referenced in the method section of the main publication)
