NOAA Diver Assembling an Acoustic Doppler Current Profiler (ADCP)

NOAA Diver and Unit Diving Supervisor Brian Degan attaches an acoustic Doppler Velocimeter (ADV) arm to a tripod mount for an Acoustic Doppler Current Profiler (ADCP) near Guayanilla, Puerto Rico. The data collected will be used to fine tune models that forecast how long corals take to recover from injuries caused by large scale disturbances.
