为了提高对亚马逊河流域水的认识，从8月78日至1月80日，每天在贝伦和马瑙斯收集雨水和水分样本。提供了所有同位素数据。在贝伦或马瑙斯，δ 18 O亏损最严重，有时低于-10 ‰，出现在雨季（1 - 4月）。本文还讨论了同位素谱型季节性差异的可能原因。
In order to improve the understanding of the water in the Amazon Basin, samples of rain and moisture were collected daily at Belem and Manaus from August 78 to January 80. All isotope data are presented. The most depleted values, sometimes lower than — 10‰ in δ18O at Belem or Manaus, were encountered during the rainy season (January-April). Possible causes of the seasonal differences in tne isotope pattern are discussed.
