Reconstructing Holocene climatic oscillations in the Indian monsoon system using cores from Himalayan (Manasbal, Tso Moiri) and central Indian (Lonar) lakes

印度次大陆的降水来自两个地区：西风带和季风。除了提供降水外，两种风况以复杂的方式相互作用，改变水分可用性和极端事件的地理模式。由于这个原因，印度没有一个单一的地点可以被认为是过去气候变化的代表-相反，来自气候敏感地区（喜马拉雅山和印度中部）的一组地点的数据需要结合起来，以获得“复合古季风曲线”，这是本项目的计划。我们的目标是重建的变化，全新世侵蚀，沉积，古生产力和植被模式的古湖泊沉积物，使用各种沉积学，地球化学和孢粉学工具。这些数据将与气候变化、水分来源和集水区动态联系起来。现代样本的调查，现代监测和花粉气候转换函数将有助于量化全新世降水变化，并确定极端气候事件及其对植被的影响。在本项目的第一年，我们的目标是调查全新世气候变率在十年尺度上的三个湖泊（Lonar，Manasbal和Tso Moriri）在选定的时间片具有更高的分辨率。根据我们的数据，我们将扩大这些湖泊的记录（长度和分辨率），并在第二阶段将我们的覆盖范围扩大到东印度湖泊。在Z项目中，正在通过采集和调查短岩心来调查东印度湖泊的气候敏感性。

The Indian subcontinent receives precipitation from two regimes: the westerlies and the monsoon. Aside from providing the precipitation, the two wind regimes interact in complex manners to alter the geographical patterns of moisture availability, and extreme events. For this reason no single site in India can be considered to be representative of past climate variability – rather data from a suite of sites from climatically sensitive regions (Himalaya and central India) needs to be combined to obtain a “composite palaeomonsoon curve”, as is planned in this project. We aim to reconstruct changes in the Holocene erosional, sedimentation, palaeoproductivity, and vegetation patterns from palaeolake sediments using a variety of sedimentological, geochemical and palynological tools. This data will be linked to climate variability, moisture sources, and catchment area dynamics. Investigation on modern samples, modern monitoring and pollen-climate transfer functions will help in the quantification of Holocene precipitation changes, and identification of extreme climate events and their impact on the vegetation.In the first years of this project we aim to investigate the Holocene climate variability in three lakes (Lonar, Manasbal and Tso Moriri) in decadal scale with higher resolution in selected time slices. Based on our data, we will extend the record in these lakes (length and resolution) and extend our coverage to the East Indian lakes in the second phase. The climate sensitivity of the East Indian lakes is being investigated in the Z project by raising and investigating short cores.
