A persistent issue that researchers have faced in paleoenvironmental reconstructions from Antarctic sediments is the difficulties in accurately dating cores using traditional radiocarbon (14C) methods. The inability to determine the age of sedimentary deposits greatly limits the utility of the hundreds of sediment samples collected around the Antarctic margin since the 1960s. During the Last Glacial Maximum (LGM), the Ross Embayment contained a large, grounded ice sheet that extended to the continental shelf edge. The ice retreat history and transition from a grounded ice sheet to a floating ice shelf is constrained in the western and central Ross Sea but unconstrained in the Eastern sector. Key limiting factors in better constraining the retreat history are having geographically well-positioned sediment cores and the ability to construct reliable and precise age models. This report presents paleomagnetic data from selected sediment cores in the eastern and central Ross Sea and from beneath the Ross Ice ... |
