Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Topsail, North Carolina. View looking northwest along the North Carolina shore. Elevated storm-induced water levels overtopped the low dunes here causing the dune to overwash. Sand was transported landward, burying the marsh (green arrow).

The relatively new camera stations at Santa Cruz and Madeira Beach have not yet imaged many rip channels, so this is an example from the U.S. Army Corps of Engineers Field Research Facility in Duck, North Carolina. In this time-averaged image from video taken September 1, 2015, the dark horizontal bands perpendicular to the beach indicate rip channels.

This USGS vessel acquires single-beam bathymetry in shallow nearshore environments. We acquire repeat bathymetry surveys over multiple years and compute changes in bathymetry, thus allowing us to identify hotspots of erosion and deposition on short timescales.

Concrete and stainless-steel marker photographed 17 years after being installed into the reef in 1998 by Harold Hudson, NOAA. Scraping and grazing by parrotfish, chemical erosion from sponges, and wave action all combine to winnow away the dead skeletons of coral—a process known as reef erosion.
