Download or read book The Dielectric Properties of Sea Ice in the Frequency Range from 26 GHz to 40 GHz written by Robert Clark Byrd and published by . This book was released on 1972 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dielectric properties of sea ice are measured for frequencies from 26 GHz to 40 GHz. The effect of temperature and salinity on the complex permittivity are determined. The orientation of the brine cells within the sea ice is found to have an effect on the loss tangent of the ice. An average value for the real part of the complex permittivity is derived along with an empirical expression for determining loss tangent.

Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 68. Human activities in the polar regions have undergone incredible changes in this century. Among these changes is the revolution that satellites have brought about in obtaining information concerning polar geophysical processes. Satellites have flown for about three decades, and the polar regions have been the subject of their routine surveillance for more than half that time. Our observations of polar regions have evolved from happenstance ship sightings and isolated harbor icing records to routine global records obtained by those satellites. Thanks to such abundant data, we now know a great deal about the ice-covered seas, which constitute about 10% of the Earth's surface. This explosion of information about sea ice has fascinated scientists for some 20 years. We are now at a point of transition in sea ice studies; we are concerned less about ice itself and more about its role in the climate system. This change in emphasis has been the prime stimulus for this book.

Download or read book An Analysis of the Tensor Dielectric Constant of Sea Ice at Microwave Frequencies written by A. Stogryn and published by . This book was released on 1985 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study has concentrated on deriving equations for computing the tensor dielectric constant of sea ice and making comparisons of the computations with published measurements on various components of the dielectric tensor (as well as attenuation coefficients, which are closely related to the dielectric constant). The theory is shown to be able to account quantitatively for large parts of the published experimental data on a variety of ice types in the frequency range 0.1 to 40 ghz and temperatures from -5 to -30 C.A few discrepancies, however, are noted. It is not known whether further development of the theory will be required to resolve the theory will be required to resolve these difference between theory and experiment or whether the experiments themselves must be refined. It is well known that accurate dielectric constant measurements on sea ice present some rather difficult experimental problems. Some inconsistencies within the existing body of experimental data itself are pointed out in this work.

Download or read book Microwave and Structural Properties of Saline Ice written by Anthony Jack Gow and published by . This book was released on 1987 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The structure and salinity characteristics of saline ice slabs removed from ice sheets grown in an outdoor pool have been studied and related to the complex relative dielectric permittivity measured with free-space transmission techniques at 4.80 and 9.50 GHz. The saline ice closely simulated arctic sea ice in its structural and salinity characteristics, which were regularly monitored in a number of ice sheets grown during the winters of 1983-84 and 1984-85. In-situ transmission measurements at similar frequencies were also made on the ice sheets themselves using antennas located above and beneath the ice. The slab measurements were made during warming from -29 to -2 C on slabs grown during the winter of 1983-84 (4.75 GHz) and during a warming and cooling cycle over a slightly larger temperature range on slabs grown during the winter of 1984-85 (4.80 and 9.50 GHz). Keywords: Dielectric properties; Microwave properties; Sea ice; and Structural properties.
