elevation difference maps of Seaside Heights, New Jersey

Detailed Description

Pre-storm elevation map, post-storm elevation map, and elevation difference map of Seaside Heights, New Jersey. Storm surge and waves eroded the beach, overwashed the dunes, and deposited sand on the island. The boardwalk, which had been built on the dunes, and several buildings were destroyed. The line of dark green features, indicating higher elevations in the Post Sandy image, shows the remnants of the boardwalk.

In the pre- and post-storm elevation maps, orange and red colors indicate higher elevations while yellow and green colors indicate lower elevations. In the elevation difference maps, red colors indicate erosion such as shoreline retreat, and blue-green colors indicate accretion, such as overwash deposits where waves and surge have moved sand landward. Maps are oriented with the Atlantic Ocean on the bottom.
