9902971PerryThis proposal is a request for funds for two people to travel to Yucatan, Mexico to collect water samples in the wake of Tropical Storm Mitch. That storm passed directly over the area in which I have been studying groundwater geochemistry and hydrogeology for several years. The samples collected will be analyzed for their isotopic composition of oxygen and hydrogen, and the results will be compared with measurements on samples collected in 1996 and (mostly) in 1997 (Perry et al, 1997). The principal objective of this study is to compare the isotopic composition of pairs of deep and shallow groundwater samples. As many sampling sites as possible will be localities that have been sampled previously (Table I and Fig.1) in order to have a basis with which to compare post-storm observations. It is important that these samples be collected as soon as possible after the storm, before mixing can take place within the aquifer.

9902971佩里这份提案是为两个人在热带风暴米奇过后前往墨西哥尤卡坦半岛收集水样而申请的资金。 那次风暴直接经过了我研究地下水地球化学和水文地质学几年的地区。 将对收集的样品进行氧和氢同位素组成分析，并将结果与1996年和（大部分）1997年收集的样品的测量结果进行比较（佩里等人，1997年）。 本研究的主要目的是比较深、浅层地下水样品的同位素组成。 尽可能多的采样点将是以前采样过的地方（表I和图1），以便有一个基础来比较风暴后的观测结果。 重要的是，在风暴过后，在含水层内发生混合之前，尽快收集这些样本。
