be used to quantitatively reconstruct past salinity and 2 H/1 H ratios of environmental water,
and in some cases precipitation rate. This approach is based on the observation that net 2 H-
and 13 C-fractionation increases and decreases, respectively, with the salinity of
environmental water. In order to better understand the mechanisms underlying these
empirical observations and ultimately improve estimates of paleoprecipitation from the …
