General Information

A 255 meter long, 9.8 cm diameter, core drilled near the front of the Ross Ice Shelf, Antarctica, during the International Geophysical Year. The core was dry drilled with a Failing rotary well-drilling rig to 249 m. The hole was then filled with diesel fuel for pressure balance and drilling continued. Drilling stopped on 5 December 1958 at 255 m, 2 or 3 m above the base of the ice, when sea water entered the hole and rose to 188 m. The archive at NSF-ICF is not continuous.
