Preface
Résumé
Presentations at three sessions entitled "Diversity of Hydrothermal Systems at Slow-Spreading Ocean Ridges" convened by P. A. Rona, R. Reves-Sohn, B. J. Murton, J. Dyment, and C. W. Devey at the American Geophysical Union (AGU) 2005 Fall Meeting initiated preparation of this volume. We thank R. Reves-Sohn for his strong constructive role in this process. C. R. German provided highly valued guidance for preparation of the volume. The authors are the heroes of this volume for advancing and communicating knowledge of seafloor hydrothermal systems. We are grateful to the reviewers who did yeoman's duty in advising the authors on how to improve their manuscripts.
