Oceanographic evidences of the great floods in 2,000 and 1,500 BC documented in archaeological records

Abstract

Based on the artifacts, a number of climatic changes in the past are documented in archaeological investigations which are reported to have been the causes for the rise and fall of human civilizations. The credibility of such studies increases, if supportEd. by parallel climatic records preserved in the sea. Nevertheless, the oceans have been a mystery to us until recent times, a source not only of admiration and awe but of confirming speculations of paleoenvironmental conditions mentioned in literature. The unique contribution of the marine sediments has been for deciphering the changes in the oceanographic conditions due to climatic variations in the past. Since the main aim Oceanography and Archaeology lies in the illumination of the past, it is apparent to bring coherence between the two. As a model, one such attempt is made in the present study. We have confirmed the major inferences independently drawn through archaeological and oceanographic means about the changes in paleoprecipitational history over the Indian region during the last 4.5 thousand year (A.M.S. dates)
