The Workshop


In October 2004, Canada hosted the 5th annual Arctic Coastal Dynamics Workshop. Despite Canada’s vested interest in Arctic coasts, it was the first time the workshop was held in this country. McGill University hosted 50 of the world’s top arctic coastal scientists from October 13 to 16. One of the main themes of ACD 2004 was the interdisciplinary investigation of permafrost and carbon related issues in Arctic coastal areas, however a new theme being introduced at the Canadian workshop was the impact of coastal change on the inhabitants of the Arctic shore zones.

 

Background Information



Arctic continental shelves comprise 30% of the area of the Arctic Ocean and contribute about 20% of the world's continental shelf area. This extensive circum-Arctic coastal margin, about 200,000 km long, is the interface through which land-shelf exchanges are mediated. Sediment input to the Arctic shelf resulting from erosion of ice-rich, permafrost-dominated coastlines may be equal to or greater than input from river discharge. Determining sediment sources and transport rates along high latitude coasts and inner shelves is critical for interpreting the geological history of the shelves and for predictions of future behavior of these coasts in response to climatic and sea level changes.
Though generally only a few kilometers wide (except in the vicinity of large deltas), the coastal zone of the Arctic Ocean is the site of dramatic changes in not only the land and ocean but also in the cryosphere and biosphere. The Arctic coastlines are highly variable, can be stable or extremely dynamic and are the site of most of the human activity that occurs at high latitudes. Extraction of natural resources occurs in many locations around the Arctic Ocean creating the need for port facilities and the potential for pollution. These pressures are only likely to increase with time.
