Book excerpt: This study investigates the relative influence of various parameters on the kinetic friction coefficient mu sub k between ice and different surfaces. Friction tests were performed with urea-doped, columnar ice, studying the parameters of normal pressure, velocity, type of material, material roughness, ice orientation, ice hardness and test configuration. Tests were conducted by pulling a sample of ice over a sheet of material and by pulling a sample of material over an ice sheet. An ambient temperature of -1.5 + or - 1 deg C was maintained throughout, and the ice surface hardness was measured using a specially designed apparatus. The results of the friction tests revealed that the behavior of mu sub k with varying velocity was significantly influenced by the test configuration and material roughness. The magnitude of the kinetic friction coefficient was also affected by varying normal pressure, surface roughness and ice hardness. Additional guidelines for standardized ice friction tests and future investigations were recommended.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the first series of conventional triaxial tests carried out on columnar first year sea ice samples obtained from the field and tested under controlled laboratory conditions using a large-capacity test machine. A total of 110 horizontal ice samples from Prudhoe Bay, Alaska, were tested on a closed-loop electro-hydraulic test machine at -10 C in unconfined and confined constant-strain-rate compression. The confined tests were conducted in a conventional triaxial cell that maintained a constant ratio between the radial and axial stress to simulate in situ loading conditions. The load ratios used were 0.25, 0.50 and 0.75. The strain rate of each test was constant at 0.01, 0.001, or 0.00001/s. Data are presented on the strength, failure strain and initial tangent modulus of the first year sea ice under these loading conditions. The effects of confining pressure, strain rate and ice structure on the mechanical properties of the ice are examined.

Download or read book Antarctic Sector of the Pacific written by G.P. Glasby and published by Elsevier. This book was released on 1989-02-07 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Antarctic Sector of the Pacific covers the area between Australia and South America south of about 45°S. The region comprises about 6% of the Earth's surface and is amongst the most remote, hostile and least studied of the world's oceans. The scientific importance of the region is derived from its role in the reconstruction of Gondwanaland, its influence on Pacific climate and palaeoclimate and its biological productivity. No systematic surveys of the region have been undertaken since the work of the U.S.N.S. Eltanin (1962-1972). The comprehensive reassessment of whale stocks by the International Whaling Commission in 1990 and problems with ratification of the Antarctic Minerals Regime attest to the importance of Antarctic matters at present.The book will stimulate scientific activity in the region and serve as a handbook for future research. It should also appeal to oceanographers and Polar scientists.

Download or read book Marine Structures Engineering Specialized Applications written by Gregory Tsinker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine Structures Engineering is designed to help engineers meet the growing worldwide demand for construction of new ports and the modernization of existing ports and terminals. It provides an authoritative guide to the design, construction, rehabilitation, repair, and maintenance of port and harbor structures. Each chapter is self-contained, allowing readers to access specific information. The Author draws on his extensive experience in offshore structure and port engineering to demonstrate evaluation, rehabilitation, repair, and maintenance of in-service marine structures. Also covered in detail are state-of-the-art approaches to: *marine structures in cold regions, with special attention to the role of ice loads, permafrost, and other ice effects *shiplifts, marine railways, shipways, and dry docks *offshore moorings *floating breakwaters *marinas *structures that protect bridge piers from ship impact. Offering practical information on all aspects of marine structures, this book serves as an indispensable resource to all engineers and professionals involved in design, construction, maintenance, and modernization of ports and harbors.

Download or read book On Sea Ice written by Willy Weeks and published by University of Alaska Press. This book was released on 2010-06-15 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering more than seven percent of the earth’s surface, sea ice is crucial to the functioning of the biosphere—and is a key component in our attempts to understand and combat climate change. With On Sea Ice, geophysicist W. F. Weeks delivers a natural history of sea ice, a fully comprehensive and up-to-date account of our knowledge of its creation, change, and function. The volume begins with the earliest recorded observations of sea ice, from 350 BC, but the majority of its information is drawn from the period after 1950, when detailed study of sea ice became widespread. Weeks delves into both micro-level characteristics—internal structure, component properties, and phase relations—and the macro-level nature of sea ice, such as salinity, growth, and decay. He also explains the mechanics of ice pack drift and the recently observed changes in ice extent and thickness. An unparalleled account of a natural phenomenon that will be of increasing importance as the earth’s temperature rises, On Sea Ice will unquestionably be the standard for years to come.
