Arctic Coastal Dynamics Report of the 4th International Workshop VNIIOkeangeologia, St. Petersburg (Russia), 10-13 November 2003 Edited by Volker Rachold and Georgy Cherkashov Volker Rachold, Alfred Wegener Institute, Research Unit Potsdam, Telegrafenberg A43, 14473 Potsdam, Germany Georgy Cherkashov, VNIIOkeangeologia (Institute for Geology and Mineral Resources of the Ocean), Angliysky prospect 1, 190121 St. Petersburg, Russia Preface Arctic Coastal Dynamics (ACD) is a joint project of the International Arctic Sciences Committee (IASC) and the International Permafrost Association (IPA) and a regional project of IGBP-LOICZ (International Geosphere-Biosphere Programme – Land- Ocean Interactions in the Coastal Zone). 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 fourth IASC-sponsored ACD workshop was held in St. Petersburg, Russia, on November 10-13, 2003. Participants from Canada (7), Germany (7), Great Britain (2), the Netherlands (1), Norway (1), Russia (32), Ukraine (1) and the United States (8) attended. During the first part of the workshop, 63 papers dealing with regional and/or circum-Arctic coastal dynamics were presented. Based on the material presented, five thematic working groups were identified: (1) GIS working group to develop of a circum-Arctic coastal GIS system, (2) coastal permafrost working group to discuss processes involved in the transition of onshore to offshore permafrost, (3) biogeochemistry working group with the focus on transport and fate of eroded material (4) biodiversity working group to initiate planning of an Arctic Coastal Biodiversity research agenda, (5) environmental data working group to discuss coastal dynamics as a function of environmental forcing. Finally, the results of the workshop and the next steps 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. Additional support of ACD activities is provided by the International Permafrost Association (IPA), INTAS (International Association for the promotion of co-operation with scientists from the New Independent States of the former Soviet Union), the International Arctic Research Center (IARC), and the Canadian Department of Foreign Affairs and International Trade (DFAIT).
