Late quaternary fluctuations in carbonate and carbonate ion content in the northern Indian ocean

Abstract

The proposed research is aimed to understand the Late Quaternary fluctuations in carbonate and carbonate ion content in the northern Indian Ocean with the following specific objectives: 1) To identify suitable paleocarbonate ion proxy/proxies for understanding calcite dissolution in the Indian Ocean. 2) To compare these proxies within themselves and use of these proxy/proxies in identifying calcite dissolution events and understanding the dissolution mechanisms on the seafloor. 3) To understand the dependency of planktonic foraminiferal shell weights on initial growth conditions i.e. carbonate ion and/or temperature from tropical waters. 4) To reconstruct the carbonate ion content for the northern Indian Ocean during the Late Quaternary.
