A preliminary study of the sedimentary history of Lake Vanda, Antarctica: Climatic implications

Abstract

Abstract We have analysed sections of DVDP4 sediment core from Lake Vanda, Antarctica for total dissolved salt, calcium carbonate, organic carbon, biogenic silica, nitrogen, and phosphorus. Three peaks of these chemical constituents appear with depth in the top 91 cm of sediment core. It is thought that these three peaks represent cold and/or dry paleoclimatic events. This work, together with other published data from Lake Vanda, indicates that the sediments contain a useful climatic history of Wright Valley.
