Abstract

Ice-coring electric thermal drills are designed for continuous or discrete sampling in glaciers, ice sheets, and sea and lake ice covers. Coring is performed using a heated annular coring head that melts the ice around the desired core. Meltwater may be left down in shallow holes in temperate glaciers, can be removed from the borehole into a chamber above the core barrel or via intermittent bailing, replaced with non-freezing drilling fluid or hydrophilic antifreeze must be added and mixed with the meltwater. Electric thermal coring drills are particularly effective in temperate and polythermal glaciers.
