  • This book presents a fluid mechanics perspective to the dynamics of fronts and vortices and their interaction with waves in geophysical flows. It provides a basic physical background for modeling coherent structures in a geophysical context, and it gives essential information on advanced topics such as spontaneous wave emission and wavemomentum transfer in geophysical flows. Based on a set of lectures by leading specialists, this text is targeted at graduate students, researchers and engineers in geophysics and environmental fluid mechanics. ...

  • Earth as an Evolving Planetary System presents the key topics and questions relating to the evolution of the Earth's crust and mantle over the last four billion years. It examines the role of plate tectonics in the geological past via geological evidence and proposed plate reconstruction. Kent Condie synthesizes data from the fields of oceanography, geophysics, planetology, and geochemistry to examine the key topics and questions relating to the evolution of the Earth's crust and mantle.

  • The present volume documents a fireside discussion with the world renowned oceanographer, Walter Munk, and gives the reader, whether scientist or surfer, a rare insight into a lifetime of passion for oceanography and geophysics. The book highlights the pioneering contributions Walter has made to wave prediction, ocean circulation, tides and their role in the Earth’s dynamics, internal waves, and ocean acoustic thermometry. It celebrates his zest for life and family, as well as his lasting curiosity. Munk’s career, spanning 70 years of innovation, has inspired generations...

  • The Alaskan-Aleutian arc has a history of rupturing in large and great earthquakes. The most recent sequence began in 1938 and has ruptured almost the entire arc from southern Alaska to the western Aleutians (Figure 1). This sequence includes five great earthquakes: the 1938 Alaskan, 1946 Aleutian, 1957 (Central) Aleutian, 1964 Prince William Sound (or Alaskan), and 1965 Rat Islands earthquakes. Three of these five-the 1957, 1964, and 1965 earthquakes-are among the 10 largest earthquakes of the 20th century. These earthquakes are clearly important to those who assess seismic hazards.

  • Signal processing has been playing an increasingly important role in remote sensing, though most remote sensing literatures are concerned with remote sensing images. Many data received by remote sensors such as microwave and geophysical sensors, are signals or waveforms, which can be processed by analog and digital signal processing techniques.

  • Significant advances in subsurface containment technology occurred in the 1990s, both with the improvement of the technology and the broader acceptance and applications as a measure for environmental remediation. Since 1995, the U.S. Department of Energy (USDOE), U.S. Environmental Protection Agency (USEPA), and DuPont have collaborated on a series of organized efforts to advance this technology. In that year, these collaborators sponsored an international expert workshop that led to the publication of the first major book on containment technology.

  • Satellite altimetry was developed in the 1960s soon after the flight of artificial satellites became a reality. From the vantage point in space, a radar altimeter is able to measure the shape of the sea surface globally and frequently. Such measurements have a wide range of applications to oceanography, geodesy, and geophysics. The results are often revolutionary. For example, in oceanography; it takes a ship weeks or months to cross the ocean making measurements while the ocean is constantly changing its circulation, temperature, and salinity.

  • Geo-electrical tomographical software plays a crucial role in geophysical research. However, imported software is expensive and does not provide much customizability, which is essential for more advanced geophysical study. Besides, these programs are unable to exploit the full potential of modern hardware, so the running time is inadequate for large-scale geophysical surveys. It is therefore an essential task to develop domestic software for overcoming all these problems.
