Arctic Coastal Dynarnics Report of the 5" International Workshop McGill University, Montreal (Canada), 13-16 October 2004 Edited by Volker Rachold, Hugues Lantuit, Nicole Couture and Wayne Pollard Ber.

Its overall objective is to improve our understanding of circum- Arctic coastal dynamics as a function of environmental forcing, coastal geology and cryology and morphodynamic behavior. The fifth IASC-sponsored ACD workshop was held in Montreal, Canada, on October 13-16, 2004. Participants from Canada (20), Gerrnany (3), Malaysia (I), the Netherlands (1), Norway (I), Russia (14), and the United States (6) attended. The objective of the workshop was to review the Status of ACD according to the Science and Implementation Plan, with the main focus On completing the circum-Arctic ACD segmentation and classification and initiating the development of web-deliverable GIS products. During the first Part of the workshop, Progress reports of the working groups of the last workshop held in St. Petersburg (Russia) in November 2003 were presented, as were 44 scientific Papers dealing with regional andlor circum-Arctic coastal dynamics. In addition to the established ACD working groups On (1) GIS Development, (2) Transition fiom Onshore to Offshore Perrnafrost and (3) Environmental Forcing, a new theme introduced at the Canadian workshop was (4) the Human Dimensions of Arctic Coastal Dynarnics. Finally, the results of the workshop and the next steps to be taken were discussed in the ACD Steering Committee meeting. The present report summarizes the program of the workshop and the main results. Financial support from the International Arctic Sciences Committee (IASC) is highly appreciated and was essential for conducting the workshop. The Canadian Department of Foreign Affairs and International Trade (DFAIT) and the Canadian International Development Agency (CIDA) provided support for six Russian participants.
