Available in PDF, EPUB and Kindle. Book excerpt: The polar regions, perhaps more than any other places on Earth, give the geophysical scientist a sense of exploration. This sensibility is genuine, for not only is high-latitude ?eldwork arduous with many locations seldom or never visited, but there remains much fundamental knowledge yet to be discovered about how the polar regions interact with the global climate system. The range of opportunities for new discovery becomes strikingly clear when we realize that the high latitudes are not one region but are really two vastly di?erent worlds. The high Arctic is a frozen ocean surrounded by land, and is home to fragile ecosystems and unique modes of human habitation. The Antarctic is a frozen continent without regular human habitation, covered by ice sheets taller than many mountain ranges and surrounded by the Earth’s most forbidding ocean. When we consider global change as applied to the Arctic, we discuss impacts to a region whose surface and lower atmospheric temperatures are near the triple point of water throughout much of the year. The most consistent signatures of climate warming have occurred at northern high latitudes (IPCC, 2001), and the potential impacts of a few degrees increase in surface temperature include a reduction in sea ice extent, a positive feedback to climate warming due to lowering of surface albedo, and changes to surface runo? that might a?ect the Arctic Ocean’s salinity and circulation.

This book was released on 1978 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "... In our previous study (Tam and Keelty 1977), we recommended a sea-ice thickness sensor system consisting of an infrared imaging device and a VHF pulse radar. The former would be used for identifying ice type and the latter as a depth sounder. Since the infrared imaging device is commercially available, only the VHF pulse radar required research and development. ... In stage 2 of this program, we have investigated the problem of horizontal resolution much further and have made a detailed design study on the electronics and the hardware required. Results of our investigation show that it is possible to achieve the horizontal resolution required without relying entirely on the antenna beamwidth. ... the essential parameters for the design of the VHF radar sea-ice thickness sensor are outlined in section 2, the antenna requirements are discussed in section 3, section 4 describes different candidate antennas and section 5 discusses several techniques that may be useful for obtaining the high horizontal resolution required. In section 6, the VHF radar backscattering from rough surfaces and its relevance to the sea-ice sensor system is discussed. Section 7 gives the summary and the conclusion of this part of the study. Recommendations of this study are presented in section 8. (Au)"--ASTIS [online] database.

Download or read book Investigation of Radar Backscattering from Second Year Sea Ice written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07-08 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scattering properties of second-year ice were studied in an experiment at Mould Bay in April 1983. Radar backscattering measurements were made at frequencies of 5.2, 9.6, 13.6, and 16.6 GHz for vertical polarization, horizontal polarization and cross polarizations, with incidence angles ranging from 15 to 70 deg. The results indicate that the second-year ice scattering characteristics were different from first-year ice and also different from multiyear ice. The fading properties of radar signals were studied and compared with experimental data. The influence of snow cover on sea ice can be evaluated by accounting for the increase in the number of independent samples from snow volume with respect to that for bare ice surface. A technique for calculating the snow depth was established by this principle and a reasonable agreement has been observed. It appears that this is a usable way to measure depth in snow or other snow-like media using radar. Lei, Guang-Tsai and Moore, Richard K. and Gogineni, S. P. Unspecified Center...

Available in PDF, EPUB and Kindle. Book excerpt: Ground-penetrating radar (GPR) is a rapidly developing field that has seen tremendous progress over the past 15 years. The development of GPR spans aspects of geophysical science, technology, and a wide range of scientific and engineering applications. It is the breadth of applications that has made GPR such a valuable tool in the geophysical consulting and geotechnical engineering industries, has lead to its rapid development, and inspired new areas of research in academia. The topic of GPR has gone from not even being mentioned in geophysical texts ten years ago to being the focus of hundreds of research papers and special issues of journals dedicated to the topic. The explosion of primary literature devoted to GPR technology, theory and applications, has lead to a strong demand for an up-to-date synthesis and overview of this rapidly developing field. Because there are specifics in the utilization of GPR for different applications, a review of the current state of development of the applications along with the fundamental theory is required. This book will provide sufficient detail to allow both practitioners and newcomers to the area of GPR to use it as a handbook and primary research reference. *Review of GPR theory and applications by leaders in the field*Up-to-date information and references*Effective handbook and primary research reference for both experienced practitioners and newcomers
