Drilling and Coring of Frozen Ground in Northern Alaska, Spring 1979.
Frozen samples of perennially frozen ground were obtained from 33 holes drilled at six locations in the National Petroleum Reserve - Alaska in the spring of 1979. Total depth of drilling was 510 m (1670 ft), of which 178 m (584 ft) was cored. The objectives of the program were to define the location...

Summary: | Frozen samples of perennially frozen ground were obtained from 33 holes drilled at six locations in the National Petroleum Reserve - Alaska in the spring of 1979. Total depth of drilling was 510 m (1670 ft), of which 178 m (584 ft) was cored. The objectives of the program were to define the location and extent of segregated and massive ice at each location and to determine the origins and ages of the ground ice through studies of the hole stratigraphy and future laboratory analyses of core samples. |
