, 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

We present techniques for obtaining large (∼100 L STP) samples of ancient air for analysis of ¹⁴C of methane (¹⁴CH₄) and other trace constituents. Paleoatmospheric ¹⁴CH₄ measurements should constrain the fossil fraction of past methane budgets, as well ...

Rheologisch-Glaziologische Untersuchungen om Firngebeit des Grönländischen Inlandeises.
, 1968 The results of the rheological-glaciological investigations, which were conducted mainly at the Jarl-Joset Station at the time of the International Glaciological Greenland Expedition in 1957- 60, are dealt with in two sections. In the first section, four

Instruments and Methods Snow density for measuring surface mass balance using the stake method [PDF]
, 2007 A measure of snow density is required to estimate water equivalent ice-sheet surface mass balance (SMB) from stake measurements. Previous studies have utilized the snow density at different depths within the snow.
