USGS geomorphologist Pat Limber drives an all-terrain vehicle equipped with differential GPS, on Ellwood Beach in Goleta, California, collecting topographic, or elevation and contour, data. These data, accurate to about 1 inch (about 2 centimeters) both horizontally and vertically, are used to monitor seasonal beach changes.

Jackson Currie of the USGS Pacific Coastal and Marine Science Center drives a personal watercraft (PWC) offshore of Butterfly Beach in Montecito, California. The equipment on the PWC collects bathymetry, or depth, data which is used to map the nearshore. USGS has been mapping this area twice yearly—every spring and fall—since 2005.

USGS volunteer Josh Brown on Santa Claus Beach, Carpinteria, at the start of a 14-mile walking survey of southern California beaches. The differential GPS equipment carried in the backpack collects elevation, or topographic, data of the beach, accurate to about 1 inch (2 centimeters) both horizontally and vertically.

USGS geomorphologist Pat Limber drives an all-terrain vehicle equipped with differential GPS, on San Buenaventura Beach south of Ventura Pier, Ventura California, collects topographic, or elevation and contour, data. These data, accurate to about 1 inch (about 2 centimeters) both horizontally and vertically, are used to monitor seasonal beach changes.

Jackson Currie and Alex Snyder of the USGS Pacific Coastal and Marine Science Center drive personal watercraft (PWCs) offshore of San Ysidro and Oak Creeks, which let out onto Miramar Beach in Montecito, California.

Two USGS scientists operate personal watercraft equipped with sonar and GPS along the beachfront off San Ysidro Creek, near Fernald Point in Montecito, California. They will use the data collected to create bathymetric (depth) maps.

Patches of dark sand cling to an instrument package that collected data for approximately two weeks at the Mokelumne River site—evidence that currents at the site were strong enough to carry sand, which is heavier than mud, probably during elevated river flows following two storms in the watershed.

Dive Safety Officer (DSO) Jake Emmert from Moody Gardens Aquarium enters a flooded coastal cave beneath the tropical forest of the Yucatan Peninsula through a small open-water pool, locally known as a cenote.  Cave diving scientists John Pohlman (USGS) and David Brankovits (USGS/WHOI) will use these entrances over the coming days to access a vast network o

USGS physical scientist Cordell Johnson, at left, and USGS research oceanographer Jessie Lacy, both from the Pacific Coastal and Marine Science Center, guide a tripod with instruments into the waters of the Mokelumne River near the confluence with the San Joaquin River. The Mokelumne is part of the vast Sacramento-San Joaquin River Delta in California,&nbs

The remnants of an eroding marsh sit on a bayside beach behind Long Beach Island, New Jersey. Marsh loss and bayside erosion can be outcomes of both natural landscape evolution and human modification of coastal barrier systems.
