SGER: Developing Proxies and Age Models for Reconstructing Monsoon Evolution on Peninsular India and in the Northern Indian Ocean

为私人投资机构提供资金，通过使用从阿拉伯海和孟加拉湾收集的、由美国和印度联合天然气水合物方案提供的岩芯，评估印度洋季风的初步代理记录。PI将对海洋表面温度、盐度、地表水来源和大陆植被类型进行测年和分析。这一分析将把现有的数据集从15 Ma扩展到30 Ma，并导致对印度和亚洲大陆的古降雨记录有更详细的了解。这些岩心是独一无二的，记录可以追溯到中新世--季风环流的潜在起点。更广泛的影响包括研究生和博士后研究员的参与。该项目将促进与印度同行的更大合作，还可能导致IODP未来在该地区进行钻探探险。

Funds are provided for the PIs to evaluate preliminary proxy records for the Indian Ocean Monsoon by using cores collected from the Arabian Sea and the Bay of Bengal and made available by the joint US and Indian Gas Hydrate Program. The PI will perform dating and analysis of sea surface temperature, salinity, sources of surface water, and continental vegetation types. This analysis will extend the existing dataset from 15 Ma to up to 30 Ma and lead to a greater detailed understanding of the Paleo rainfall record of the Indian and Asian continents. These cores are unique and the record goes back to the Miocene - the potential initiation of the monsoonal circulation. Broader impacts include involvement of a graduate student and a post-doctoral fellow. This project will foster greater collaboration with Indian counterparts and could also lead to future drilling expeditions by IODP in the area.
