Late Pleistocene-Holocene biogeochemical evidence of relative sea level, landscape changes in the Cauvery delta, India
Description
We conducted multi-proxy studies on a 14 m deep core (+7m a.m.s.l.) from the Cauvery Delta. Our study suggests evidence of a huge hiatus between 190-10 ka and 58-10 ka on account of role of relative sea level rise due to slumping/tectonic adjustments rather than lack of sediment deposition in this region. With the help of C, N, S isotopes, palynofacies investigations, and geochemical fingerprinting, we marked major alteration and relative changes from the past ~58 ka. The study is an important example for understanding coastal dynamics of tropical countries in particular and global sea level changes in response to climate.

Steps to reproduce
The data presented in this study were generated as part of research aimed at developing multiproxy records to enhance the understanding of coastal processes along the east coast of India—a region particularly vulnerable to ongoing climate change impacts such as sea level rise, landscape alteration, and coastal slumping/erosion. All data were produced at the nationally recognized, state-of-the-art facilities of the Birbal Sahni Institute of Palaeosciences, Lucknow, using established and standardized analytical protocols.
