Among the specialized equipment at the Army Corps of Engineers' Field Research Facility is a motorized, threewheeled vehicle with a stable platform atop a 35-foot tripod frame. The Coastal Research Amphibious Buggy, or CRAB, can be driven from the beach into the ocean, in wave heights up to six feet, to install and service instruments, to collect sediment samples, or to map the ocean bottom.
