DELORES tracks (2007-2008)

2007-2008 tracks

In the austral season of 2007-08 the British Antarctic Survey’s oversnow radar system DELORES (DEep-Look Radar Echo Sounder) was operated across Pine Island Glacier, successfully sounding the bed in all 1500 km of profiles obtained.

Variations in the amplitudes of the basal returns, corrected for ice thickness – a property termed Bed Reflection Power (BRP) – represent variations in basal conditions beneath the ice, and are commonly interpreted as variations in subglacial geology and sediment distributions, and variations in basal water content, with brighter returns reflecting higher water content and warmer conditions at the basal interface.
