Through the drought, drip discharge fell to base flow, drip Ca²⁺ concentrations fell by half and drip Mg/Ca and Sr/Ca increased in a co-varying pattern. Calcite Mg/Ca and Sr/Ca predicted from drip waters displayed a marked increase through, and just beyond, the period of greatest moisture deficit. The results suggest that stalagmites from shallow caves in drought-sensitive eastern Australia potentially preserve a valuable record of El Niño-La Niña history. 2010-04-27T06:24:08.159Z ]]>
