Abstract: [1] We present glaciological and climatological characteristics of Hercules Dome, Antarctica (86°S, 105°W), which demonstrate its potential as a deep ice core site. Annual layering in dD ratios from a 72 m ice core collected by the US-ITASE 2002 traverse indicate accumulation rates of 0.16-0.20 m/yr ice equivalent over the last 300 years. Age control from stratigraphy seen in the radio-echo sounding data collected during the same traverse suggests a rate of 0.09-0.11 m/yr averaged over the past 18,000 years. …
