The Coastal Research Amphibious Buggy or CRAB is a 10.7 m tall amphibious vehicle. Its primary use is to accurately map the nearshore coastal bottoms. By being able to drive along on the bottom, the CRAB is unaffected by the wave and current motion that affect surveys from boats.
These photos were taken at the Coastal and Hydraulics Laboratory Duck Field Research Facility (FRF). The primary mission of the FRF is to collect measurements of the waves, currents, winds, and sediment movement, and to understand the relations between them.
Here's a video clip of the CRAB (2.1 MB).
