Benjamin Norris in a mangrove forest on the southern edge of the island of Cù Lao Dung, situated in the lower Mekong Delta, Vietnam. Ben is carrying a Nortek Vectrino Profiler, a high-resolution velocity sensor, which is attached to a custom-made frame that can be driven by hand into the soft sediment of the mangrove forest to collect data.

Reflectors are placed throughout a lidar scan area to help reference where the lidar points are in space. Andrew Stevens, USGS, surveys Capitola Beach, walks past a reflector mounted on a tall, yellow tripod in front of the light blue building.

Knowing how much sand is removed and returned by big storm events can help show how waterfronts, like this one in Capitola, change with time.

USGS geologist Bruce Richmond prepares to deploy a pipe dredge that will be dragged along the seabed to collect sediment.

Example of a deep-penetration multichannel seismic-reflection profile collected offshore of San Mateo County, from the USGS National Archive of Marine Seismic Surveys (NAMSS). The profile shows a cross-section of the earth's crust from the surface down to a depth of about 3 kilometers.
