Thermal electric ice-core drills: history and new design options for intermediate-depth drilling
Ice coring of temperate and polythermal glaciers demonstrates some limitations of most electromechanical (EM) and thermal electric (TE) drills. Most TE drills are heavy, require a heavy power system, work slowly and cannot operate in boreholes going through the cold–temperate ice transition. Antifreeze thermal electric drills (ATED) are capable of operating in polar ice caps, polythermal and te...
متن کاملIntermediate depth ice core drilling support systems : power generators and shelters
Arctic and high altitude ice coring operations require lightweight and efficient equipment. Power sources. fuel and shelter in some cases compose up to 50'J6 of the cargo delivered to a drill ing ite. Solar panel , twotroke gasoline and air-cooled portable diesel generato rs have been u ed in Arctic a.nd high a lt itude glacier to power the drilling etup. On the ummit of Mt. Ki limanjaro (589S ...
متن کاملAntifreeze thermal ice core drilling: an effective approach to the acquisition of ice cores
Antifreeze thermal electric drills have a long history of ice drilling in temperate, subpolar and polar glaciers. Shallow, intermediate and deep ice cores have been obtained in Arctic, Antarctic and on high elevation glaciers. Many merits and drawbacks of antifreeze thermal technology have been discovered over the past 25 years. A modified version of the antifreeze thermal electric ice coring d...
متن کاملAnnotations for Portable Intermediate Languages
This paper identifies high-level program properties that can be discovered by static analysis in a compiler front end, and that are useful for classical low-level optimizations. We suggest how intermediate language code could be annotated to convey these properties to the code generator.
متن کاملGlaciological and climatic significance of Hercules Dome, Antarctica: An optimal site for deep ice core drilling
[1] We present glaciological and climatological characteristics of Hercules Dome, Antarctica (86 S, 105 W), which demonstrate its potential as a deep ice core site. Annual layering in dD ratios from a 72 m ice core collected by the US-ITASE 2002 traverse indicate accumulation rates of 0.16–0.20 m/yr ice equivalent over the last 300 years. Age control from stratigraphy seen in the radio-echo sou...
