THE PRESIDENT’S PAGE The 63rd annual meeting of the Eastern Snow Conference (ESC) was held at the University of Delaware in Newark, Delaware (7–9 June 2006). There were sessions on snow and climate, remote sensing of snow processes, and glacial and periglacial processes. The quality of the presentations was exceptional and I thank all who shared their data at the meeting. The success of the 2006 meeting rests with the Executive. I thank Delphis Levia, who, along with Andrew Klein and Miles Ecclestone, made all the local arrangements; our treasurers, Derrill Cowing and Miles Ecclestone, for keeping us in the black; and Claude Duguay (VP and Program Chair) for organizing and running the 63rd meeting. Andrew Klein, our Webmaster, has helped the ESC join the digital age. I also thank our Corporate members (listed in the Foreword) for their continued support of the ESC. The winner of this year’s Weisnet Medal for the best student paper was Y.C. Chung for his work on the influence of the snow–soil moisture flux on snowpack metamorphism. The Campbell Scientific Medal, which is awarded to the best student paper in which instrumentation plays a key role, was awarded to Gernot Koboltschnig for his investigation into the potential of using a water balance model with high temporal resolution for distributed modeling of melting at high elevation. The ESC Proceedings have been published for 63 years. I find this a remarkable feat for a small organization run by a handful of researchers. Editing the proceedings is one of the most time-consuming jobs and I thank our Editors, Dr. Robert Hellström and Susan Frankenstein, for their hard work. This is also the eleventh anniversary of ESC’s partnership with Hydrological Processes, in which a number of the papers presented at the conference are published. I thank Hydrological Processes for providing ESC participants the opportunity to publish in the journal, and Dr. John Pomeroy and Dr. Andrew Klein for handling the Hydrological Processes submissions. I invite you to attend the 64th meeting of the Eastern Snow Conference, to be held in conjunction with the Canadian Meteorological and Oceanographic Society, the Canadian Geophysical Society, and the American Meteorological Society at the end of May 2007 in St. John’s, Newfoundland. Please visit our Web site (www.easternsnow.org) for up-to-date details of this meeting. xi Best Regards, Claude Duguay 63rd President Eastern Snow Conference
