variableName: d18O
units: permil
description: carbonate
basis: Also, the instrumented lake level of Lake Qinghai and coeval d18OC variations is correlated over the last w50 years (Henderson et al., 2003). Because lake level is influenced by effective moisture, d18OC would be expected to be a good proxy for P/E.
