variableName: d18O
units: permil
description: carbonate
basis: Trace element (Mg and Sr) concentrations in ostracod shells from Lakes Salpete ?n and Pete ?n Itza ? parallel the ?18O records, suggesting that ?18O records ref ect basin hydrology rather than changes in the isotopic composition of rainfall (Rosenmeier et al., in press). Furthermore, covariance in both ?18O and Mg eliminate temperature as a control on the oxygen isotope record.
