AB: Jack Dymond was an extremely unique scientist and colleague. His high level of professional ambition, risk-taking, and accomplishment were largely hidden behind a gentle and open-minded demeanor which always had room for thoughtful consideration of new ideas and different points of view. Although very different in personality, Jack shared with Degens and Edmonds the ability to encourage us to think broadly, globally, and to apply our expertise and knowledge to systems with which we might not be so familiar or comfortable. Jack believed that studying multiple systems was the best way to truly unravel the geochemical fingerprints recorded in sediments and rocks, thus leading us to a better understanding of how the earth, how Gaia, really works. To this end, Jack applied oceanographic techniques and concepts of marine geochemical cycling to large lakes of the world and encouraged a new generation of oceanographers to do the same. His exhaustive study of Crater Lake involving numerous oceanographic colleagues, and his collaboration with Siberian scientists working on Lake Baikal, provided extraordinary new insights into lacustrine hydrothermal systems which generated significant worldwide interest. Jack was an integrated thinker, an enthusiastic collaborator, and a great source of support and encouragement for his colleagues. His big picture view of the earth and its processes, many of which he knew intimately, was never intimidating, only enlightening. He drew upon his vast research experience and systems approach to demystify for his students and the public the important feed-backs between the biosphere, atmosphere, and lithosphere. In this manner, he made some of his most important contributions to science by providing the public and young scientists with an understanding and appreciation of the dynamic links between earth processes and global climate change.
