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.

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.

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.

A peat auger core collected from the back-barrier marsh of Assateague Island, Maryland. An inorganic-rich layer found at the top of the core was delivered to the marsh via Hurricane Sandy. Visual contrast in sediment down-core reveal similar layers as that observed at the top of the core (i.e., Hurricane Sandy layer).
