Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
This book is dedicated to curious individuals and explorers of knowledge and technologies that have not been awarded a Nobel prize (yet). It has been written for tinkerers who want to employ tools to analyze the near subsoil (less than 20 m) with what is at hand.
The percentage composition of the subject matter of this revised edition is approximately the same as that for the first, but the number of chapters has increased significantly. This necessitated the publication of a companion volume. In addition to dealing with various geophysical exploration methods, it adds and emphasizes the use of radiometric methods to explore for hard minerals found in sediments on and beneath the ocean floor.
Full-3D seismic waveform inversion (F3DWI) refers to inversions that seek to minimize the discrepancies between the observed and synthetic seismic waveforms, wiggle for wiggle, by solving the three-dimensional acoustic or (visco) elastic wave equations. Its development is important both for the theoretical foundations of modern quantitative seismology and for the practical applications of seismological methods in exploring the Earth’s interior.
Electrical Resistivity (ER) is a non-destructive geophysical method for geotechnical and geoenvironmental investigation. This technique is promising in producing soil moisture map and obtaining subsoil profile information. Additionally, the saturated and unsaturated soil parameters can be evaluated through the electrical resistivity method. The saturated and unsaturated soil properties are critical parameters for earthen infrastructure design, especially the landfill bottom liners and top covers, whereas the soil hydraulic properties play a significant role in the overall performance.

Electromagnetic Methods in Applied Geophysics, Volume I, Theory presented the mathematical and physical foundations common to all EM methods. The purpose of Volume I was to help facilitate the understanding of the theory involved and to provide a limited amount of interpretational aids. Volume H, Applications is devoted to a method-by-method treatment of the principal EM techniques in common use.
In Australia, the period from 1920 to the present is split by World War II into two sharply contrasting periods with respect to advances in knowledge of the geology of the continent. Between the two world wars geological work was almost entirely restricted to the Geological Surveys and universities of the six states. The official Geological Surveys were more and more confined to routine and ad hoc tasks, such as examination of mines and prospects, siting water bores, and giving assistance to prospectors and the mining industry generally.
Since 1993, the Geophysical Turbulence Program at the National Center for Atmospheric Research together with the National Science Foundation has sponsored interdisciplinary workshops each summer in Boulder, CO. The general theme of the workshops relates to turbulence research but with a wide community focus. The material in this volume arose out of a workshop held in October of 1995. The purpose of the workshop was to bring together researchers and students working on both astrophysical and geophysical systems, in which convection was an important effect.
Электроразведка – один из ведущих геофизических методов, применяемых при геологоразведочных работах для решения широкого круга геологических задач, характеризуется многообразием методов, их модификаций, разветвленностью вариантов и методик. Каждый отдельный метод и каждая модификация метода или его вариант отличаются не только методикой полевых работ, но и имеют свою специфику обработки и интерпретации результатов полевых наблюдений.
В монографии представлено описание новых методов анализа данных систем геофизического мониторинга. Область исследований относится к проблематике теории обработки прямых экспериментальных данных и связана с мониторингом и прогнозом состояния околоземного пространства. Особое внимание в книге уделено методам анализа данных в периоды солнечных событий, магнитных и ионосферных бурь.
