Access to clean water is a human right and a basic requirement for economic development. The safest kind of water supply is the use of groundwater. Since groundwater normally has a natural protection against pollution by the covering layers, only minor water treatment is required.
Detailed knowledge on the extent, hydraulic properties, and vulnerability of groundwater reservoirs is necessary to enable a sustainable use of the resources.

The seismic method plays a prominent role in the search for hydrocarbons. Seismic exploration consists of three main stages: data acquisition, processing, and interpretation. This book is intended to help the seismic analyst understand the fundamentals of the techniques used in processing seismic data. In particular, emphasis is given to the practical aspects of data analysis.

This book is divided into four parts. The introduction (Part I) provides the physical background of the geophysical models that are analyzed in this book from a mathematical viewpoint.
Part II is devoted to a self-contained proof of the existence of weak (or strong) solutions to the incompressible Navier–Stokes equations.

Part III deals with the rapidly rotating Navier–Stokes equations, first in the whole space, where dispersion effects are considered. Then the case where the domain has periodic boundary conditions is considered, and finally rotating Navier–Stokes equations between two plates are studied, both in the case of horizontal coordinates in R2 and periodic.
In Part IV the stability of Ekman boundary layers, and boundary layer effects in magnetohydrodynamics and quasigeostrophic equations are discussed.

The boundary layers which appear near vertical walls are presented and formally linked with the classical Prandlt equations. Finally spherical layers are introduced, whose study is completely open.

The mining towns in northern Canada are remote from good roads but they are surrounded by lakes. Aircraft, mounted on floats instead of wheels, serve as a practical means of transport in the forested wilderness. After the ice had melted from the lakes in the early summer of 1961, I found myself —a young Scot with a good recent degree in physics but minimum training for the task ahead—disembarking from a float-plane on the shore of a large lake in northern Manitoba, 80 kilometres from the nearest town where the mining company that employed me had its headquarters. My companions were five Cree Indians and a cook, and for the rest of the short northern summer my job would be to use geophysical equipment to search for potential sources of nickel in the geological structures buried beneath the forest floor. This was my initiation to the world of geophysical exploration. It convinced me to change from physics to a career as a geophysicist. In addition to teaching and laboratory research it involved annual fieldwork that took me into less developed areas of the world where interesting geological problems could be addressed.

В книге рассмотрены принципы действия, устройство и технические характеристики высокоточных лазерных дальномерных устройств и тензометров. Приводятся результаты экспериментов, выполненных при помощи этих устройств (измерения расстояний между пунктами земной поверхности и расстояний до Луны и искусственных спутников Земли; исследование тектоники разлома Сан-Андеас в Калифорнии; изучение вековых деформаций земной коры и деформаций, обусловленных земными приливами и землетрясениями).
Описаны конструктивные особенности лазерного интерферометра для абсолютных определений ускорения силы тяжести и гетеродинного лазерного интерферометра для измерения скорости вращения Земли.
Книга рассчитана на инженеров геодезистов, геофизиков и астрономов.

С 31 мая по 12 июня 1976 года Вычислительный центр СО АН СССР проводил Всесоюзную школу по неклассаческим методам в геофизике с участием иностранных ученых
В первую половину работы Школы ведущие ученые А.Н.Тихонов, М.М.Лаврентьев, В.Н.Арсенин, В.Г.Романов и другие прочли учебные курсы лекций по теории условно-корректных и обратных задач математической физики. Вторая половина работы Школы была отведена под часовые доклады и краткие сообщения по неклассическим методам математики и их приложения к физике. Тексты этих докладов и сообщений публикуются в настоящем сборнике.
В целом работа Школы способствовала знакомству геофизиков и прикладных математиков с теорией так называемых некорректных и обратных задач, а также взаимной информации о работе ученых разных стран народной демократии и разных районов Советского Союза.
Сборник представляет интерес для специалистов по прикладной математике и геофизике, а также для студентов старших курсов этих специальностей.

Geophysics is the study of the physics of the earth, its surface, interior, and surrounding environment in space. An important part of geophysics is seismology. Seismic waves are vibrations that travel through the earth’s interior or along its surface. Seismology is the study of how seismic waves can be used to determine the interior structure of the earth. Earthquake seismology is concerned with the structure of the entire earth, whereas exploration seismology deals with only the upper few kilometers of the earth’s crust. In earthquake seismology, the source is passive, because the signals are earthquakes, which naturally occur within the remote medium (the subterranean earth). In exploration seismology, the source is active, because the signals are generated intentionally in the accessible medium (the surface or near-surface of the earth). <...>

This book provides a general introduction to the most important methods of geophysical exploration. These methods represent a primary tool for investigation of the subsurface and are applicable to a very wide range of problems. Although their main application is in prospecting for natural resources, the methods are also used, for example, as an aid to geological surveying, as a means of deriving information on the Earth’s internal physical properties, and in engineering or archaeological site investigations. Consequently, geophysical exploration is of importance not only to geophysicists but also to geologists, physicists, engineers and archaeologists. The book covers the physical principles, methodology, interpretational procedures and fields of application of the various survey methods.The main emphasis has been placed on seismic methods because these represent the most extensively used techniques, being routinely and widely employed by the oil industry in prospecting for hydrocarbons. Since this is an introductory text we have not attempted to be completely comprehensive in our coverage of the subject. Readers seeking further information on any of the survey methods described should refer to the more advanced texts listed at the end of each chapter. <...>
