Elevation difference maps of Island Beach State Park, New Jersey

Pre-storm elevation map, post-storm elevation map, and elevation difference map of Island Beach State Park, New Jersey. The beach and the seaward facing side of the dunes were eroded in this lightly developed park area. Storm surge and waves deposited sand behind the first line of dunes and sand covered part of the parking lot.

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.
