Abstract

A simple mass balance model provides insight into the hydrologic, isotopic, and chemical responses of Lake Titicaca to past climatic changes. Latest Pleistocene climate of the Altiplano is assumed to have been 20% wetter and 5°C colder than today, based on previous modelling. The simulation of lacustrine change since 15,000 cal yr B.P. is forced by these modeled climate changes. Here the AA. employ an isotopic and chemical model in order to assess the magnitude of hydrologic changes required to produce the observed lake-level changes and to investigate the expected isotopic and chemical response of the lake to water balance changes
