Sturgeon Island UAV Mapping

Coastlines are migrating upland faster than at any point in recorded history. As dunes and coastal marshes disappear, the need for littoral adaptation increases. In recognition of this, the United States Army Corps of Engineers (USACE) has placed increasing importance on developing sediment placement strategies for restoring deteriorating coastal wetlands. These strategies, however, are still experimental and need to be monitored to track their performance. The EMLab is assisting The Wetlands Institute and USACE in monitoring and analyzing a recent sediment placement on Sturgeon Island in the Great Sound Bay of New Jersey.
