^P. Fretwell. Bedmap2: improved ice bed, surface and thickness datasets for Antarctica(PDF). The Cryosphere. 31 July 2012 [1 December 2015]. (原始内容存档(PDF)于2020-02-16). Using data largely collected during the 1970s, Drewry et al. (1992), estimated the potential sea-level contribution of the Antarctic ice sheets to be in the range of 60-72 m; for Bedmap1 this value was 57 m (Lythe et al., 2001), and for Bedmap2 it is 58 m.
