P2C2: Extend the Record of the Indian Summer Monsoon Variability to the Past 2000 Years with Inter-Annually Resolved Speleothem Isotopic Records from the Core Monzoon Zone of India

提供资金，以发展一个网络的跨年度解决代理记录降水从核心季风区的印度使用的氧同位素组成的石笋从战略位置的洞穴在整个核心季风区的印度。 这项研究的最终科学目标是开发一个过去2,000年季风降雨变化的复合记录，作为全印度降雨时间序列的“古等价物”。 这将作为一个基准，以评估印度夏季风（ISM）的变化，并将其世纪降水变化的背景下，在过去的2,000年。此外，本研究产生的季风代用数据集将与过去2,000年的仪器和代用数据集进行比较，以检查耦合的大气-海洋模式的变化，如大西洋年代际振荡（AMO）和厄尔尼诺-南方涛动（ENSO）。 这项研究将有助于提高印度季风预测能力的年际到十年的时间尺度。更广泛的影响涉及一个强大的教育指导部分和同样强大的智力部分。 该提案支持本科生在一个主要以本科生为中心的机构。 修订后的项目包括对高级论文的支持。 帮助更好地理解ISM的科学目标本身就是一个重要的科学目标，特别是因为季风系统直接和间接地影响着这么多人。

Funding is provided to develop a network of inter-annually resolved proxy records of precipitation from the core monsoon zone of India using the oxygen isotope composition of stalagmites from strategically located caves throughout the core monsoon zone of India. The ultimate science goal of the research is to develop a composite record of monsoon rainfall variability of the past 2,000 years as a 'paleo-equivalent' of the All India Rainfall time series. This will serve as a benchmark to assess the variability of the Indian Summer Monsoon (ISM) and to place its 20th century precipitation variability in the context of the past 2,000 years. Additionally, monsoon proxy data sets resulting from this research will be compared to the instrumental and proxy data sets of last 2,000 years to examine variability in coupled atmosphere-ocean modes such as the Atlantic Multidecadal Oscillation (AMO) and the El Nino- Southern Oscillation (ENSO). This research will help improve Indian monsoon predictive capabilities on inter-annual to decadal timescales.The broader impacts involve a strong educational mentoring portion and an equally strong intellectual portion. The proposal supports undergraduate students at a primarily undergraduate-centered institution. The revised project includes support for a senior thesis. The science goal of helping to develop a better understanding of the ISM is an important scientific aim in itself but especially since the monsoon system directly and indirectly affects such a large number of people.
