The lake sediments in ice free areas (oases) of Antarctica hold a record of paleoclimate history of the earth. A view of drilling operations to retrieve sediment cores in one of the lakes. 

Abstract: The sea-level change reconstructed for the last three million years shows that the sea-level has been higher by 5 m than the present when global temperatures were warmer by 2oC than that which existed during the pre-industrial level.
