Popis:	Tree-ring chronologies were derived from two coniferous species growing in the foothills of the Patagonian Andes of Argentina, using crossdating and standardization techniques developed by the Laboratory of Tree-Ring Research. Seven of these chronologies were selected, along with data from two long reliable gaging stations to reconstruct annual stream-flow for two major rivers extending back to the year 1601. Calibration between tree-ring and river flow data was established using the multivariate technique of canonical analysis. Correlations of 0.73 were obtained between gaged and reconstructed flow for both rivers. These Andean conifers contain good climatic and hydrological information and tree-ring chronology and calibration techniques are capable of extracting much of this information.
