Current meter at Davidson Seamount

This photograph shows a very sensitive instrument for measuring currents that MBARI researchers placed on Davidson Seamount, about 120 kilometers (75 miles) southwest of Monterey Bay. The researchers were trying to determine how seafloor currents affect the growth of the sponges and corals that are abundant on the high points of this underwater mountain. This instrument is called an acoustic doppler current profiler (ADCP). It measures underwater currents by bouncing sound waves off of tiny particles and creatures that are being carried along with the currents. Image credit: (c) 2006 MBARI / NOAA
