Book Synopsis Deep Rotary Core Drilling in Ice by : G. Robert Lange
Download or read book Deep Rotary Core Drilling in Ice written by G. Robert Lange and published by . This book was released on 1973 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rotary drilling equipment was modified and used to obtain cores from glaciers in Northwest Greenland, Byrd Station and Little America V, Antarctica. Using cold compressed air, specially designed bits and other modifications, cores were obtained to 1345 feet in Greenland, 1000 feet at Byrd Station and the Ross Ice Shelf was penetrated to a depth of 840 feet at Little America V. In all locations cracks in the core appeared with increasing frequency at depth due to the sudden release of the overburden load when the core was cut in the air-filled hole. Special equipment and techniques developed dealt with the problem with some success. (Author Modified Abstract).

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a review of thermal ice drilling technologies, including the design, parameters, and performance of various tools and drills for making holes in ice sheets, ice caps, mountain glaciers, ice shelves, and sea ice. In recent years, interest in thermal drilling technology has increased as a result of subglacial lake explorations and extraterrestrial investigations. The book focuses on the latest ice drilling technologies, but also discusses the historical development of ice drilling tools and devices over the last 100 years to offer valuable insights into what is possible and what not to do in the future. Featuring numerous figures and pictures, many of them published for the first time, it is intended for specialists working in ice-core sciences, polar oceanography, drilling engineers and glaciologists, and is also a useful reference for researchers and graduate students working in engineering and cold-regions technology.

Book Synopsis Stratigraphic Analysis of a Deep Ice Core from Greenland by : C. C Langway (Jr)
Download or read book Stratigraphic Analysis of a Deep Ice Core from Greenland written by C. C Langway (Jr) and published by . This book was released on 1967 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: A deep rotary core drilling project in 1957 at Site 2 on the Greenland ice sheet (76 deg 59 min N, 56 deg 04 min W) provided ice core to a depth of 411 m. The vertical variation in bulk density, macroscopic structure, oxygen isotope ratios, ionic constituents, and extraterrestrial dust (black spherules) were analyzed using both field and laboratory technqies. These data permit the direct estimate of annual accumulation layers in the core. Continuous stratigraphic measurements and observations were made over the upper 110 m of the profile and detailed physical and chemical analyses were made on continuous 1.3 to 3.9-m core increments at 100, 200, 300 and 411-m depths. The average total ionic concentration in the ice sheet ranges between 0.65 and 1.35 mg/liter. The annual global mass deposit of black spherules as calculated from these studies varies from 2.10 x 10,000 metric tons in 700 year old ice to 6.57 x 10,000 metric tons in 12 year old firn. The oxygen isotope ratio variation provides the best means of estimating accumulation at depth. Results of the investigations indicate rates of net snow accumulation of 42.3, 34.2, 37.4, 41.1 and 41.6 g/sq cm -yr at the surface, A.D. c. 1773, c. 1513, c. 1233 and c. 934, respectively. Accumulation data and other physical and chemical evidence allow climatological inferences to be made over the 10-century profile. The ice core record shows that snow accumulation and temperature in A.D. 934 were similar to today, followed by a gradual decrease in accumulation to a minimum around the late 18th century and an increase in both accumulation and temperature from A.D. 1773 to 1957 and following.

Book Synopsis General Considerations for Drill System Design by : Malcolm Mellor
Download or read book General Considerations for Drill System Design written by Malcolm Mellor and published by . This book was released on 1975 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drilling systems are discussed in general terms, component functions common to all systems are identified, and a simple classification is drawn up in order to outline relations between penetration, material removal, hole wall support, and ground conditions. Energy and power requirements for penetration of ice and frozen ground are analyzed for both mechanical and thermal processes. Power requirements for removal of material and for hoisting of drill strings are considered, and total power requirements for complete systems are assessed. Performance data for drilling systems working in ice and frozen ground are reviewed, and results are analyzed to obtain specific energy values. Specific energy data are assembled for drag-bit cutting, normal impact and indentation, liquid jet attack, and thermal penetration. Torque and axial force capabilities of typical rotary drilling systems are reviewed and analyzed. The overall intent is to provide data and quantitative guidance that can lead to systematic design procedures for drilling systems for cold regions.
