USGS scientists collect sediment samples in a gas hydrates area during a cruise on the U.S. Atlantic margin in 2015.

The effects of sea-level rise will vary by differences in the geomorphology and ecology of the landscape.  Images show marsh (top left) rocky coast (top right), barrier beach (bottom left), and coastal bluff (bottom right)

USGS employee Owen Brenner walks across the Fire Island wilderness breach carrying a GPS backpack that allows him to collect precise elevation data in the shallows.

USGS scientist BJ Reynolds sets up a solar-powered, satellite-uplinked GPS base station in the Fire Island Wilderness Area to support detailed elevation surveys.

Cliff erosion is a common storm-induced hazard along the West Coast. Two condemned apartment buildings along Esplanade Avenue in Pacifica, California are shown here before their demolition in 2016 and 2017.

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Oregon Inlet, North Carolina. View looking west along the North Carolina shore. High waves and storm surge from Hurricane Joaquin eroded the beach and inundated the low area in the backshore at Oregon Inlet (A, green box, blue arrows).

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Rodanthe, North Carolina. View looking west along the North Carolina shore. High waves and storm surge from Hurricane Joaquin eroded the beach, exposing the pilings of the homes to wave attack (green and orange arrows).

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Salvo, North Carolina. View looking west along the North Carolina shore. Waves and surge from Hurricane Joaquin eroded the beach, causing significant shoreline retreat and a narrower beach, leaving deposits of darker sand at the base of the dune (green arrow).

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Hatteras, North Carolina. View looking north along the North Carolina shore. Waves and surge from Hurricane Joaquin eroded the beach, causing significant shoreline retreat and a narrower beach at the location of the Hurricane Isabel breach in 2003 (green arrow).

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of New Drum Inlet, Core Banks, North Carolina. View looking northwest along the North Carolina shore.

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Bear Inlet, North Carolina. View looking northwest along the North Carolina shore. High waves and storm surge from Hurricane Joaquin eroded the beaches, moving sand inland (green arrow) and reshaping the flood-tidal shoals.

Near vertical (top, middle) and low angle oblique (bottom) aerial photographs of Camp Lejeune, North Carolina. View looking northwest along the North Carolina shore. Waves and surge from Hurricane Joaquin eroded the beach, causing significant shoreline retreat and a narrower beach.

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).
