LEOPOLDO, Paulo Rodolfo et al. Composição isotópica da água de chuva e da água do solo em floresta amazônica do tipo terra firme, região de Manaus. Acta Amaz. [online]. 1982, vol.12, suppl.3, pp.7-13. ISSN 0044-5967.

It was possible to observe the rain water values of δ2H e δ18O and theirs respective repartition, including the soil water until the depth of 1.20m. The work was done in the Model Basin in an experimental area near the Km 14 of the ZF-2 road. The obtained results showed that the isotopic composition of the rain water vary with the season of the year, and are more enriched in 2H and 18O in the period wich begins at the end of April and beginning of November. These variations were not observed in the igarapé Tarumã-Açu water, suggesting a blend of waters and a high storage of water by the soil.
