Brief Description (Abstract):

Thirtyfive moss tufts, lichen patches, frozen soil and glacial ice samples collected from Schirmacher Oasis has been pollen analyzed in order to understand the interplay of pollen and spores deposited in the sediments. The occurrence of diversified pollen-spore types suggests their long distance transport of thousands of kilometers ranging from tropical to temperate floristic regions from distant continents and surrounding Islands of Antarctic mainland. The palynological study of a 50 cm sediment profile from Long lake under 4-6 meter water column reflects two fold climatic oscillations viz., cool & humid and cool & more humid since last 2000 years BR The palynological data has provided an insight into the potential of the lake sediment studies from the polar region. The occurrence of palynodebris under lichen patches in Antarctic environment is interesting which needs more detail study. The study of air catches also supports the study of pollen dispersal in polar region.

Status: Completed

Purpose: The main objective of the present work is to understand the distribution of palynodebris on Antarctic surface deposits initially and subsequently this transmitted pollen data could be used to decipher Early Holocene chmatic oscillation exhibited by lake sediment in Polar Region.
