Geochemical Analysis of Ancient Salt Deposits from the Dead Sea and its Climate and Hydrology During Warmer Periods in the Past 200,000 Years

通过对国际大陆科学钻探项目(ICDP)从死海海底获取的460米钻芯的化学分析，可以推断出过去20万年来中东的气候和水文状况。在11.5万到13万年前沉积的厚厚的盐层意味着干旱条件。可以将这一时期中东的气候和水文与其他地区的结果进行比较，以了解它们是如何在全球范围内联系在一起的。使用过去的证据可以检验我们的理论，并拓宽我们对未来气候如何反应的理解。该项目将通过来自约旦和以色列的学生的参与，加强目前和未来的国际科学合作。死海钻探项目发现的钻探岩芯含有厚厚的盐层，记录了11.5万到13万年前中东的干旱状况。该项目将通过分析困在盐层中的流体气泡的化学成分，重建过去20万年来较温暖时期的气候和水文。化探测量将被解释为降雨量、温度、相对湿度和风。结果将与地球历史上这一时期气候模型的预测进行比较。

The climate and hydrology in the Middle East for the last 200,000 years can be deduced from chemical analyses of 460-meters of drill core obtained from beneath the Dead Sea by the International Continental Scientific Drilling Project (ICDP). Thick layers of salt deposited between 115,000 and 130,000 years ago imply drought conditions. The climate and hydrology in the Middle East during this time period can be compared with results from other regions to understand how they are connected globally. Using evidence from the past can test our theories and broaden our understanding of how the climate will respond in the future. This project will strengthen present and future international scientific collaboration through participation of students from Jordan and Israel.Drill core recovered by the Dead Sea Drilling Project contained thick layers of salt that document drought conditions in the Middle East between 115,000 and 130,000 years ago. The project will reconstruct the climate and hydrology during warmer periods in the past 200,000 years by analyzing the chemistry of fluid bubbles trapped in the salt. Geochemical measurements will be interpreted for rainfall, temperature, relative humidity, and winds. The results will be compared with predictions from climate models for this period in earth history.
