Constraining the Englacial and Basal Thermal State in the Dome F Region, East Antarctica
Estimating the thermal state within a glacier and at the bed is important for many glaciological applications. Examples include oldest-ice reconnaissance, ice-sheet dynamics and more. However, widespread measurements of thermal profiles in glaciers are not available simply because currently temperat...
