File:Figure 3.8 - Lithological column for the upper 600m of the AND-1B drillcore.png

Lithological column and inferred glacial proximity curve for the upper 600 m of the AND-1B drillcore recovered by the ANDRILL McMurdo Ice Shelf Project (Naish et al., 2009^[1]), compared with the continuous deep-sea oxygen-isotope record (Lisiecki and Raymo, 2005^[2]) and the modelled contribution of Antarctic Ice Sheet to sea level change for the last 5 million years (Pollard and DeConto, 2009^[3]). The “glacial proximity” column shows glacial surfaces of erosion, which mark boundaries of orbital-scale, glacimarine sedimentary cycles, and the prospect of cycles missing on account of erosion. The glacial proximity curve tracks the cycles themselves from inferred depositional environment - I = ice contact, P = proximal glacimarine, D = distal glacimarine, M = open marine. Pairs of images of the Antarctic Ice Sheet on the right show hypothesized glacial and interglacial states for the last million years and the period between 1 and ~5 Ma from Pollard and DeConto (2009^[3]). Figure adapted by Tim Naish from Naish et al. (2009^[1]).
