Josh Logan operates a drone carrying a precision GPS and special camera to map the shore at Long Beach, Washington. USGS scientists used the same system for detailed mapping of beaches beside Monterey Bay, California. 

Flow from San Gregorio Creek in San Gregorio, California is often blocked by a natural sand levee when the flow is not strong enough to push through to the Pacific Ocean.

Sediment consolidation in an oedometer provides constraints on how much the reservoir sediment is likely to compact while methane from the reservoir’s gas hydrate is extracted as an energy resource.  Compaction data helps engineers optimize the construction and operation of wells that target gas hydrate reservoirs.
