Continental shelf drift deposit indicates non-steady state Antarctic bottom water production in the Holocene

A late Quaternay, current-lain sediment drift deposit over 30 metres in thickness has been discovered on the continental shelf of East Antarctica in an 850 metre deep glacial trough off George Vth Land. Radiocarbon dating indicates that a period of rapid deposition on the drift occurred in the mid-Holocene, between about 3 000 and 5 000 years before present.
