Brief Description (Abstract):

A short 78 cm sediment core (L2) from a fresh water lake in Larsemann Hills, East Antarctica was obtained during the 26th Indian Scientific Expedition to Antarctica in austral summer (January to March 2007). The sediment core samples was analyzed for grain size distribution and biological productivity indicator such as Total Organic Carbon (TOC) and Biogenic Silica (BSi %). The sediment core represented the time period of ~8.3 cal ka BP. The values of BSi from the core showed prominent high productivity from ~8.3 to ~6 cal ka BP in comparison to less productivity in mid-late Holocene (~6 cal ka BP to recent). Moreover, high sand (%) infers the glacio-fluvial deposition from ~8.3 to ~5 cal ka BP. TOC showed little variation throughout the core, except in the upper ~ 10 cm (~4 cal ka BP) part wherein it was comparatively high.

Status: Completed

Purpose: The main objectives of this study are to reconstruct paleoclimatic variation and to understand the biogeochemical behavior of the lake during late Quaternary period.
