      • d18O (LS10CLTA): interpretation2_basis: ‘These exceptionally low values suggest that factors other than effective moisture must have contributed to the pronounced variations in the Takahula Lake d18O record. Increased winter precipitation associated with a westerly Aleutian Low position may account for 1 permil of the d18O decrease. Other factors leading to the 18O-depletion during these periods probably include decreased temperatures, as well as increased lake-ice cover and associated reductions in evaporation.’ has been replaced by NULL

      • d18O (LS10CLTA): interpretation3_basis: ‘A lowering of lake level by 0.5m would turn the lake into a topographically closed basin. Under such conditions, evaporation becomes the main process of water loss, and lake-water continues to become 18Oenriched until d18O of the evaporating vapor equals d18O of the input (Gat and Levy, 1978; Leng and Marshall, 2004). In contrast, a more positive water balance than the present is expected to shorten the lake?s water-residence time, reducing the influence of evaporation on the lake?s isotope composition (Craig, 1961). Thus the d18OCc record can be used to infer qualitative changes in effective moisture.’ has been replaced by NULL
