First multi-year cumulation covers six years: 1965-70.

This book reports on the findings of, and swnmarizes the conclusions from, the Port Hacking Estuary Project, a model-guided, multidisciplinary study of an estuarine ecosystem. The Project began in 1973, at a time when it was thought that environmental problems could be solved readily by assembling a multidisciplinary team of research scientists and having them co-ordinate their research around the construction of an ecosystem model. But a decade has passed and time has not been easy on this approach. The anticipated predictive dynamic models have not been produced and bitter argument has often marred the course of such studies. Yet the need to anticipate the flow of various chemical species (carbon, oxygen, nitrogen, phosphorus, toxicants) through the environment remains: the evidence is everywhere, from fertilization of urban lakes to acid rain. The magnitude of the problem ensures that funds will continue to be made available - although with short-term variations as perceptions swing. It is thus clear that although the difficulties are great, so is the need. It is from this background that we present this book. The Port Hacking Estuary Project involved some 15 - 20 research scientists over a period of 5 years. The goal was to research the flow of carbon into, within, and out of a small unpolluted estuary chosen for convenience rather than for its social significance. The idea was to use the information obtained from these studies to build a predictive dynamic model.

This new Encyclopedia of Coastal Science stands as the latest authoritative source in the field of coastal studies, making it the standard reference work for specialists and the interested lay person. Unique in its interdisciplinary approach. This Encyclopedia features contributions by 245 well-known international specialists in their respective fields and is abundantly illustrated with line-drawings and photographs. Not only does this volume offer an extensive number of entries, it also includes various appendices, an illustrated glossary of coastal morphology and extensive bibliographic listings.

Annals of the International Geophysical Year, Volume 48: Bibliography and Index contains bibliography of articles published in connection with the International Geophysical Year (IGY). The preparatory and operational phases of the IGY occupied nearly a decade and the data accumulated in the many scientific disciplines by workers in some 67 countries will provide material for publication for many years. The references have been assembled from information supplied by a wide variety of sources. These references have been grouped into 21 sections, of which Sections I-XIV followed the discipline grouping adopted during the IGY. Within each section references have been arranged in alphabetical order according to the name of the principal author. Anonymous articles are listed at the end of each section, again arranged in alphabetical order by title. In the scientific literature, author's names originally printed in Cyrillic symbols sometimes appear with several different spellings because of the use of different transliteration systems. In the present Bibliography an attempt has been made to achieve consistency by using the same transliteration system throughout. This book will prove useful to geophysicists and researchers who are interested in the accomplishments of the International Geophysical Year.
