Core collection with the Mini Multicorer (Mini Muc) viewed from a wide-angle camera attached to the system’s frame. The weight of the Mini-Muc drives four core barrels (only three are visible) into the sediment.

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.

USGS scientist Tim Elfers conducts a bathymetric (depth) survey from a personal watercraft with onboard GPS and echo sounder equipment, in Santa Cruz, California.

Locations of the 97 beaches and barrier islands where our partners used the iPlover app to collect and record information on landcover characteristics at piping plover nesting locations during the breeding seasons of 2014-2016.

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).

Split-beam (EK60) sonar image of bubbles (green) in the water column at a seep site overlooking Baltimore Canyon on the U.S. Atlantic margin. Although the bubbles appear to nearly reach the sea surface, the methane contained in the bubbles would have dissolved and been replaced by other gases by the time the bubbles rise several hundred meters.
