Response to reviews on "High resolution boundary conditions of an old ice target near Dome C, Antarctica"

Abstract: A high-resolution (1 km line spacing) aerogeophysical survey was conducted over a region near the East Antarctic Ice Sheet's Dome C that may hold a 1.5 Myr climate record. We combined new ice thickness data derived from an airborne coherent radar sounder with unpublished data that was in part unavailable for earlier compilations, and we were able to remove older data with high positional uncertainties. We generated a revised high-resolution digital elevation model (DEM) to investigate the potential for an old … Show more

“…Furthermore, mapping of radar-detected horizons increases confidence that layering at those depths is undisturbed and facilitates age extrapolation of the maximum expected age at the coring location Parrenin et al, 2017). These uses of stratigraphic information for future drill-site selection are strongly exploited in the currently running reconnaissance studies for the International Partnership in Ice Core Sciences (IPICS) Oldest Ice target, aiming at the retrieval of a continuous 1.5 Myr old ice-core record (Brook et al, 2006;Karlsson et al, 2018;Parrenin et al, 2017;Van Liefferinge and Pattyn, 2013;Van Liefferinge et al, 2018;Young et al, 2017).…”
