Chirp profile through shoreface at Fire Island, NY

Above is a seismic profile collected from the shoreface of Fire Island, NY (Locker et al., 2017), which shows a steep shoreface, a nearshore bar, a sand ridge, and the geology beneath it all. The sediment above the blue and red lines is thought to be available for transport by waves or longshore drift. We map and quantify this volume of sediment along barrier islands, which improves estimates of shoreface sediment flux and connects geologic observations to models.
