Book Description
At South Pole Station, ground penetrating radar profiles were recorded along the surveyed S-N and W-E routes of two proposed snow tunnels that would function as future water and sewer utilidors. The radar system was operated from within the cab of a tracked vehicle that towed two antennas in a sled. The two antennas transmitted pulses centered near 900 and 400 MHz to provide near-surface detail to penetration depths of 4.1 and 15.0 m, respectively. Eight longitudinal profiles, 518 m long, were recorded along the proposed S-N water line route, and 12 longitudinal profiles, 366 m long, were recorded along the proposed W-E sewer line route. Additional S-N profiles were recorded on the W-E route to delineate a particularly intense reflection. The profiles show that both proposed corridors contain many large and small buried items. Multiple targets at depths of 3.0 to 4.9 m occur along the S-N line. Along the W-E lines, there are multiple targets at similar depths. A particular area is densely cluttered and large targets appear on multiple parallel lines. Near the dome isolated targets appear at depths as great as 7.6 m.

Book Description
"This document represents the final report of the United States Antarctic Program External Panel. The report has the unanimous approval of all 11 panel members and draws upon our collective experience which includes some 44 individual trips to Antarctica involving visits to all three U. S. stations, each research ship, support icebreakers and numerous field sites. As a panel, we visited McMurdo Station and South Pole Station and toured support facilities at Christchurch. We received approximately 70 briefings and conducted 80 “one-on-one” meetings with individuals involved in virtually all aspects of the Antarctic Program. Over 200 inputs were received in response to our request for “public comments". During visits to McMurdo and the Pole, the Panel conducted informal “Town Meetings” and was the beneficiary of numerous comments by members of those communities having first-hand experience in day-to-day operations. We are most appreciative of the candor and professionalism with which we were treated by all those with whom we came into contact, and in particular the members of the National Science Foundation who so expertly and constructively supported our efforts. We believe the U. S. Antarctic Program is well managed, involves high quality science and is important to the region as well as to the United States. We also believe that in the current budget environment, costs must be reduced, preferably through increased efficiency and “reinvention,” but, if not, through reduced scope. Recommendations are offered herein to help ensure the continued viability of the program into the 21st century."--

Book Description
"Leading the way describes how the men and women of Air Force civil engineering have provided the basing that enabled the Air Force to fly, fight, and win. This book depicts how engineers built hundreds of bases during World Wars I and II, Korea, Vietnam, the Gulf War, and Operations Enduring Freedom and Iraqi Freedom. At the same time, these engineers operated and maintained a global network of enduring, peacetime bases. It describes the engineers' role in special projects such as the ballistic missile program, the Arctic early warning sites, and construction of the U.S. Air Force Academy. Using hundreds of sources, this detailed narrative tells the story of how civil engineers have been organized, trained, equipped, and employed for more than 100 years. From the beaches of Normandy to the mountains of Afghanistan, civil engineers have forged an unmatched record of success and built a solid foundation for today's Air Force."--Back cover.

Book Description
The Department of Defense's official history of the United States Cold War missile program--completely reformatted with all-new color illustrations and photographs not used in the original edition. The DoD commissioned this study as part of its Cold War Project in 1996. With permission from the DoD's Legacy Program, Hole in the Head Press brings To Defend and Deter back into print. This informative guide offers a thorough look at Cold War missile development, from the earliest beginnings of rocketry in the 13th century to the arms control agreements that began in the 1970s. Both a narrative history and reference guide, To Defend and Deter traces the evolution of the Cold War and establishes the United States missile program's scope and its massive impact on the American landscape, citizens, and structure of the U.S. military establishment.
