Assessing shoreline evolution Coskata-Coatue Wildlife Refuge, Nantucket.

This project examines historical shoreline changes on Nantucket with the aim of assessing the processes that caused these changes. Using this knowledge, we plan to make projections of future shoreline evolution in the context of climate change. The work is funded through the Trustees and a private donor. Our study will focus on the Coskata-Coatue region, but with the understanding that coastal processes occur within a continuum and so an island-wide. We have been using Ground Penetrating Radar and historical maps and lidar to determine both post-glacial and historical shoreline evolution and quantify the volume and pattern of sand movement over the last 1.5 centuries. Understanding past and future shoreline evolution helps us understand the risk to both natural and cultural resources on this small island.
