The Core Group's recommendations were adopted at the Fourth Session of GEMSI (Curacao, 25-31 March 1982), and it was further decided that, to increase the cost effectiveness of the proposed six-month activity noted above, a detailed report would be given on the results obtained during the preliminary period with respect to identification of individual PCB components by gas chromatography and gas chromatography-mass spectrometry as well as to the distribution of individual components between solution and particulate matter. This is the subject of this publication. The methods described here are also appropriate for the estimation of several other halogenated hydrocarbons in seawater. Some of these compounds appear in the same fraction as PCB (e.g. penta- and hexa-chlorobenzene); for the estimation of more polar components, additional GC-ECD analyses are required. The extracts needed for this purpose require only relatively small additional steps in the separation procedures.

Since the book first appeared in 1976, Methods of Seawater Analysis has found widespread acceptance as a reliable and detailed source of information. Its second extended and revised edition published in 1983 reflected the rapid pace of instrumental and methodological evolution in the preceding years. The development has lost nothing of its momentum, and many methods and procedures still suffering their teething troubles then have now matured into dependable tools for the analyst. This is especially evident for trace and ultra-trace analyses of organic and inorganic seawater constituents which have diversified considerably and now require more space for their description than before. Methods to determine volatile halocarbons, dimethyl sulphide, photosynthetic pigments and natural radioactive tracers have been added as well as applications of X-ray fluorescence spectroscopy and various electrochemical methods for trace metal analysis. Another method not previously described deals with the determination of the partial pressure of carbon dioxide as part of standardised procedures to describe the marine CO2 system.

As we discover more about the role of the ocean in global changes and identify the effects of global change on the ocean, understanding its chemical composition and processes becomes increasingly paramount. However, understanding these processes requires a wide range of measurements in the vast ocean, from the sea surface to deep-ocean trenches, fr
