Intermediate depth ice core drilling support systems: power generators and shelters

Autor: Zagorodnov,V.S., Thompson,L.G., Mosley-Thompson,E., Huffman, F., Kelley, J. J.

Publikováno v: Memoirs of National Institute of Polar Research. Special issue. 56:313-320

Arctic and high altitude ice coring operations require lightweight and efficient equipment. Power sources, fuel and shelters in some cases compose up to 50% of the cargo delivered to a drilling site. Solar panels, two-stroke gasoline and air-cooled p

Controller for portable intermediate depth ice core drilling system

Autor: Zagorodnov,V.S., Huffman, F., Thompson,L.G., Mosley-Thompson,E.

Publikováno v: Memoirs of National Institute of Polar Research. Special issue. 56:321-325

The primary objective of ice core drilling is to obtain the highest quality core while minimizing the effort needed. This requires a control system with precision control and convenient operation. An intermediate-depth portable ice core drilling syst

Performance of intermediate depth portable ice core drilling system on polar and temperate glaciers

Autor: Zagorodnov,V.S., Thompson,L.G., Mosley-Thompson, E., Kelley, J.J.

Publikováno v: Memoirs of National Institute of Polar Research. Special issue. 56:67-81

A portable ice core drilling system was developed at the Byrd Polar Research Center (BPRC) and tested during four field seasons on both polar and temperate ice fields. The prime features of the new drilling system include its low power requirement, l

Ice core drilling complications

Autor: Zagorodnov,V.S., Thompson,L.G., Mosley-Thompson,E., Kelley, J.J.

Publikováno v: Memoirs of National Institute of Polar Research. Special issue. 56:196-205

A common fear for all ice drillers is a stuck drill. A less severe but important concern is a foreign object in a borehole, deflected borehole or slush formation in a borehole filled with an ethanol-water solution (EWS). Prevention is the most effici
