Brief Description (Abstract):

Pollen analysis of twenty moss turfs and Antarctic soil samples collected in and around Schumacher Oasis, East Antarctica has been carried out in order to elucidate the interplay of pollen and spores deposited in the sediments. The occurrence of different pollen-spore types reflects their long distance transport ranging from tropical to temperate floristic regions around Antarctic mainland. The palynological study of a 60 cm sediment profile from Priyadarshini lake under 6 meter water column reflects three-fold climatic oscillations viz., arid, warm & humid and warm & more humid since last 8000 years BP. The maiden palynological data has provided an insight into the potential of the further palaeoclimatic work in the region.

Status: Completed

Purpose: The main objective of the present work is to understand the distribution of palynodebris through the study of various Antarctic surface sediment in the first phase and subsequently the transmitted proxy data could be used in deciphering Early Holocene climatic changes in lake sediments. Hitherto no palynological studies were reported from the region so far.
