| Tóm tắt: | In the ten years that have passed since the publication of the first edition of this textbook
exciting advances have taken place in every discipline of geophysics.
Computer-based improvements in technology have led the way, allowing more
sophistication in the acquisition and processing of geophysical data. Advances in
mass spectrometry have made it possible to analyze minute samples of matter in
exquisite detail and have contributed to an improved understanding of the origin of
our planet and the evolution of the solar system. Space research has led to better
knowledge of the other planets in the solar system, and has revealed distant objects
in orbit around the Sun. As a result, the definition of a planet has been changed.
Satellite-based technology has provided more refined measurement of the gravity
and magnetic fields of the Earth, and has enabled direct observation from space of
minute surface changes related to volcanic and tectonic events. The structure, composition
and dynamic behavior of the deep interior of the Earth have become better
understood owing to refinements in seismic tomography. Fast computers and
sophisticated algorithms have allowed scientists to construct plausible models of
slow geodynamic behavior in the Earth’s mantle and core, and to elucidate the
processes giving rise to the Earth’s magnetic field. The application of advanced
computer analysis in high-resolution seismic reflection and ground-penetrating
radar investigations has made it possible to describe subtle features of environmental
interest in near-surface structures. Rock magnetic techniques applied to sediments
have helped us to understand slow natural processes as well as more rapid
anthropological changes that affect our environment, and to evaluate climates in the
distant geological past. Climatic history in the more recent past can now be deduced
from the analysis of temperature in boreholes. |
