Calculation tools

Reference radiocarbon values for 100% biogenic carbon, based on radiocarbon values of atmospheric CO2
These data may be freely used to obtain 14C reference values for 100% biogenic carbon, provided that reference is made to this document (webpage) in reports and also to the reference Palstra and Meijer
(2014; see reference list) in the open (scientific) literature.

Water isotope calculation tool
A thoroughly validated spreadsheet for calculating isotopic abundances (2H, 17O, 18O) for mixtures of waters with different isotopic compositions.
