Abstract Data were collected from two sites, one on the southern Wilkins and another on the southern George VI ice shelves. Both sites were investigated as potential sites of perennial firn aquifers; in the case of the southern Wilkins, an extensive firn aquifer was found (Montgomery et al., 2020). Data sources come from two early-model AMIGOS stations (Scambos et al., 2013), ice cores that were collected by hot-ring coring (Montgomery et al., 2020), and ground-penetrating radar profiles. Thermistor data from several depths within the firn core boreholes, transmitted by the AMIGOS stations, show the progression of the seasonal variations in firn temperature at the sites. Radar data show the depth of the firn aquifer (or, its absence at George VI site), and some drainage effects at a nearby rift at the Wilkins site.
