Noble Gas Paleotemperatures and Other Climate Information Derived from Groundwater Archives on the Southern Hemisphere(Southern Africa and Australia)

小行星9304573 在扩展的承压含水层中循环的地下水含有过去气候的信息。 特别是稀有气体测量，可以重建大陆古温度（“稀有气体古温度计”）。 Cl-和同位素数据（D，18 O）为长期气候变化提供了额外的见解。 该奖项支持从南半球两个地下水流系统（纳米比亚的Stampriet含水层和澳大利亚南部的Dilwyn含水层）收集和评估地球化学数据（He、Ne、Ar、Kr、H2O、14 C、13 C D、18 O、36 Cl和主要溶解离子）。 来自这些含水层的古气候记录将解决过去3万年大陆和海洋古温度与气候变化纬度对称性之间的关系。

9304573 Stute Groundwater circulating in extended confined aquifers contains information on past climates. Noble gas measurements, in particular, allow reconstruction of continental paleotemperatures ('noble gas paleothermometer'). Cl- and isotopic data (D), 18O) provide additional insight into long-term climate change. This award supports the collection and evaluation of geochemical data (He, Ne, Ar, Kr, Xe, 14C, 13C D, 18O, 36Cl and major dissolved ions) from two groundwater flow systems in the southern hemisphere, the Stampriet aquifer in Namibia and the Dilwyn aquifer in southern Australia. Paleoclimate records from these aquifers will address the relationship between continental and oceanic paleotemperatures and the latitudinal symmetry of climate change during the past 30,000 years.
