SGER: The Isotopic Signature of Tropical Storm Mitch on Groundwater in Yucatan Mexico

9902971Perry这项建议是为两个人申请资金，让他们在热带风暴米奇之后前往墨西哥尤卡坦采集水样。那场风暴直接经过了我研究地下水、地球化学和水文地质学多年的地区。收集的样本将被分析其氧和氢的同位素组成，结果将与1996年和(大部分)1997年收集的样本的测量结果进行比较(Perry等人，1997年)。这项研究的主要目的是比较成对的深水和浅水地下水样品的同位素组成。尽可能多的采样点将是以前已经抽样的地点(表I和图1)，以便有一个比较风暴后观测的基础。重要的是，在风暴过后，在含水层内进行混合之前，尽快收集这些样本。

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.
