We present a glacial record from the western Olympus Range, East Antarctica, that documents a permanent shift in the thermal regime of local glaciers, from wet to cold based, between 14.11 and 13.94 million years ago (Ma). The record includes classic wet-based tills interbedded with fossil-rich glaciolacustrine deposits overlain by a series of cold-based drifts. Chronologic control comes from A...

Hillaire-Marcel et al. bring forward several physical and geochemical arguments against our finding of an Arctic glaciolacustrine system in the past. In brief, we find that a approach to further test hypothesis should additionally consider actual bathymetry Greenland–Scotland Ridge (GSR), density maximum freshwater at 3–4°C, sensible heat flux from rivers, volumes are being mixed advected. Thei...
