Coastline (sculpture)
Coastline is an outdoor sculpture by American artist Jim Sanborn installed at the National Oceanic and Atmospheric Administration complex in Silver Spring, Maryland.
Coastline attempts to recreate the effect of waves crashing on the Atlantic coast. This is achieved with artificial waves generated by a turbine and pneumatic blower underneath the sculpture. The wave frequency is controlled by a remote tide gauge in Woods Hole, Massachusetts, that sends actual wave heights to the sculpture's control mechanism in real time. Sanborn built a quarter-size scale model of the sculpture and consulted with a wave engineer while doing research for the project.
