Coastal erosion in Newfoundland /

14 Jan 2013

This report classifies the coastline of the island of Newfoundland, focusing on the sensitivity of the coastline to erosion and petroleum contamination. [...] In some locations, the influence of seasonal ice shove results in the construction of a boulder rampart, or the emplacement of individual boulders perched on the rock substrate. [...] The development of narrow rock platforms is related primarily to the attitude of the bedrock, and its susceptibility to frost weathering, rather than to the duration or intensity of marine erosional processes. [...] Coastal sites lacking vegetation are more susceptible to frost wedging than those with vegetation cover, as the combined result of exposure of the rock to the atmosphere and removal of any potential snow cover insulation during the winter and spring. [...] Frequently, the beaches accumulate over the widest areas of the platforms, which are the areas of the bedrock that have the gentlest slopes.
