Instruments and Methods: The Measurement of Vertical Strain in Glacier Bore Holes

, 1974
A method to measure the vertical strain in glacier bore holes is described that entails placement of passive markers at varying depths. The position of these markers with respect to a surface reference is measured by an electronic sensor lowered into the

Instruments and Methods: A Steam-Operated Ice Drill for the Installation of Ablation Stakes on Glaciers

, 1965
An easily portably thermal ice drill was designed and constructed, with water vapour being used for melting the ice. A lore hole, 8 m. deep, can be drilled within about 30 min., depending on the ice properties.

Instruments and Methods: The USA CRREL Drill for Thermal Coring in Ice

, 1969
The USA CRREL drill is an 80-kg, electrothermal unit designed for continuous coring in temperate or polar ice or snow. The drill melts a hole approximately 16.3 cm in diameter and retrieves a core approximately 12.2 cm in diameter at rates from 1.9 m h−1
