5 THE ANTARCTIC DURING THE INTERNATIONAL GEOPHYSICAL YEAR discussions were held among geophysicists, biologists, geologists, and othersmdiscussions aimed at developing a medium for the publication of the papers resulting from the intensive research work being done in Antarctica. The Antarctic Research Series is designed to provide this medium, presenting authoritative work with uniformly high scientific and editorial standards from leading scientists engaged in Antarctic research. In a sense the series continues a tradition dating from the earliest days of geographic exploration and scientific expeditions--the tradition of the expeditionary volumes which set forth in rich detail everything that was seen and studied. But in much of the present Antarctic work one expedition blends into the next, and it is no longer scientifically meaningful to separate them. However, Antarctic research in all disciplines has a large degree of coherence and deserves the modern counterparto the expeditionary volumes of past decades and centuries. Papers appearing in the series represent original contributions too lengthy or otherwise unsuitable for publication in the standard scientific journals. The material published is directed not only to scientists actively engaged in the work but to graduate students and scientists in closely related fields as well. The series will serve as a source of information both for the specialist and for the layman versed in the biological and physical sciences. Many of the early volumes will be cohesive collections of research papers grouped around a central theme. An editor for each book is drawn from the discipline it represents, as are the reviewers on whom each editor relies. Early in 1963 the National Science Foundation made a grant to the American Geophysical Union to initiate the series, and a Board of Associate Editors was appointed to crystallize and implement it. To representhe broad nature of the series, the members of the Board were chosen from all fields of Antarctic research. They include Jarvis Hadley, representingeology and solid Earth geophysics; Harry W. Wells, aeronomy and geomagnetism; A. P. Crary, seisinology and glaciology; George A. Llano, botany and zoology; Waldo L. Schmitt, marine biology and oceanography; and Morton J. Rubin, meteorology. AGU staff members contributing to the Series include Judith McCombs, managing editor, and Marie L. Webner, style editor. HARRY W. WELLS Chairman, Board o/ 4ssociate Editors.tintarctic Research Series

6 ACKNOWLEDGMENTS Tuz ADMINISTRATION Of the Allan Hancock Foundation of the University of Southern California has continued to provide space and support to study the polychaetous annelids of Antarctica. Salaries of the participants in the Antarctic project were partly provided by the National Science Foundation. The charts and plates of illustrations were prepared by Carl Petterson. Meredith Jones, United States National Museum, critically read the manuscript. The staff of the library of the Allan Hancock Foundation provided the necessary bibliographic materials. The map section of the American Geographical Society supplied the outline charts on which the distributional data are recorded. The editorial staff of the American Geophysical Union, including Mrs. Nancy Jarvis, copy editor, and Mrs. Judith McCombs, managing editor, were most helpful and encouraging taking this manuscript through the editing and printing processes. The author is very grateful for all of this assistance. vii
