Hemer, M.A. and Harris, P.T. 2003. Sediment core from beneath the Amery Ice Shelf, East Antarctica, suggests mid-Holocene ice-shelf retreat. Geology 31: 127-130.
Changes in the location of the edge of the Amery Ice Shelf were inferred from measurements of biogenic opal, absolute diatom abundance and the abundance of Fragilariopsis curta found in sediments retrieved from beneath the ice shelf at a point that is currently 80 km from land's edge. The MWP at ca. 750 14C yr BP was likely warmer than at any time during the CWP.
