Summary
Summary
Changes in sea level caused by global warming can be disastrous to modern civilization. Therefore, it is important to use accurate and reliable methods to monitor any change. During this century, and, in particular, the last three decades, tide-gauge records have been used to show these changes related to the world's oceans. Aubrey and Emery suggest, however, that tidal gauges should not be used unquestioningly as a benchmark for measuring eustatic sea-level changes. Tectonism, subsidence, ocean current variability, and human activity can, and do, affect the accuracy of these records. Understanding the reasons for changes in land and sea levels is essential for the proper development of coastal regions. The results of this study provide guiding data for scientific, engineering, and policy solutions to coastal flooding. Determining the true causes of relative subsidence, and how to use geological and oceanological controls, will allow us to exist within our natural environment, rather than force nature to conform to our legal and temporary 'remedies.'

Choice Review
This well-organized and well-written book discusses the major and minor changes in relative sea level and its causes. It presents an examination of extensive tide-gauge records that show both falls as well as rises in sea level depending on location; and then data that determine if these changes in relative sea level are due to changes in the level of the water or to a rise or fall in land level. All causes of ocean level change, such as climatic warming, and all causes of land level change, both natural and due to human activity, are covered in detail. A practical application is the presentation of direction and rates of relative sea level change for different coasts of the world. An interesting section on the human identification and understanding of tides, plus the first tide tables, are included. Numerous graphs help clarify the text; the bibliography is extensive. Recommended for undergraduates and graduates and could be particularly useful to coastal-zone planners.-G. F. Crandell, Humboldt State University
