Abstract
Recent reports suggest that sediment yield to the Arctic shelf resulting from erosion of Arctic coastlines may produce quantities of sediments equal or greater than input from river discharge. The circum-Arctic coastal margin is about 200,000 km long and is the interface through which land-shelf exchanges are mediated. An understanding of the sediment sources and transport rates and mechanisms along high latitude coasts and inner shelves is critical for the interpretation of the geological history of the shelves and for predictions of future behavior under the range of climate change scenarios. The NSF-RAISE sponsored workshop held in Woods Hole, MA, November 2-4, 1999, provided documentation on regional rates of transgression and regression as a function of ice content of permafrost, near shore bathymetry, sediment transport and deposition, and sea level changes. Workshop objectives and accomplishments included: (1) development of a common classification system for coastal mapping in high-latitudes for the purpose of estimating coastal change sensitivity and erosion potential; (2) identification and description of techniques presently used for coastal mapping and erosion measurements in high-latitude environments; and (3) development of estimates of erosion rates for representative circum-Arctic coastlines. These workshop results provide input to deterministic and empirical models for coastal evolution. Participants included experts from Russia, USA, Canada, and Europe. The workshop was organize under the auspices of the Working Group on Coastal and Offshore Permafrost of the International Permafrost Association.
