The ANDRILL Program successfully recovered a 1285m-long succession of cyclic glacimarine sediment with inter-bedded volcanic deposits, in its first season of drilling from the McMurdo Ice Shelf (MIS). The MIS drillcore represents the longest and most complete (98% recovery) geological record from the Antarctic continental margin to date, and will provide a key reference record of climate and ice sheet variability through the Late Neogene. Here we present a synopsis of the Initial Results Volume (Naish et al., in press, Terra Antartica) with special emphasis on the potential of the record for improving our knowledge of
