Isotopic and elemental composition of groundwater are influenced by climatic conditions at the time of recharge and are therefore potential indicators for climate change. To date little work has been done to unravel climate information contained in deep circulating groundwater. However, it has been successfully demonstrated that in selected aquifers the isotopic composition of groundwater and the concentrations of dissolved noble gases can be related to paleotemperatures and/or past atmospheric circulation patterns. These studies raised hopes that groundwater as an archive of paleoclimate may play an important role in future climate research, but they also indicate that there are still many open questions that must be addressed. This award supports a meeting at Lamont-Doherty Geological Observatory of Columbia University to explore the potential and strategies for future paleoclimate research in this area.

地下水的同位素和元素组成 受补给时气候条件的影响， 因此是气候变化的潜在指标。 迄今 在解开气候信息方面， 深层循环地下水中所含的 然而已经 成功地证明，在选定的含水层中， 地下水的组成和溶解的浓度 稀有气体可能与古温度和/或过去有关 大气环流模式 这些研究带来了希望 地下水作为古气候的档案， 在未来的气候研究中发挥重要作用，但它们也表明， 仍然有许多悬而未决的问题需要解决。 该奖项支持在拉蒙特-多尔蒂地质会议 哥伦比亚大学的天文台，以探索潜在的， 该地区未来古气候研究的策略。
