简介
The Gulf of Carpentaria is an epicontinental sea (maximum depth 70m) between Australia and New Guinea, bordered to the east by Torres Strait (currently 12m deep) and to the west by the Arafura Sill (53m below present sea level). Throughout the Quaternary, during times of low sea-level, the Gulf was separated from the open waters of the Indian and Pacific Oceans, forming Lake Carpentaria, an isolation basin, perched above contemporaneous sea-level with outlet channels to the Arafura Sea. A preliminary interpretation is presented of the palaeoenvironments recorded in six sediment cores collected by the IMAGES program in the Gulf of Carpentaria. The longest core (approx. 15m) spans the past 130ka and includes a record of sea-level/lake-level changes, with particular complexity between 80 and 40ka when sea-level repeatedly breached and withdrew from Gulf/Lake Carpentaria. Evidence from biotic …
