This complete and up-to-date compilation of the currently employed proven methods for the chemical analysis of seawaters includes more than 200 tables and 110 figures. The author presents the methods in a logical manner so that the reader can readily learn how to perform them and understand the types of instrumentation available. It helps the practitioner to implement these methods successfully into his laboratory and to apply them uickly and reliably. In addition, the detailed description of each method enables the analyst to set up new analytical methods meeting the needs for the detection of new analytes.
