Role And The Importance Of Acoustic Doppler Current Profiler On Oceanography
Measuring current is an unavoidable practice of physical oceanographers, which helps determine ocean water movement. Water current measurement helps scientists determine how organisms, nutrients, biological and chemical constituents travel across the ocean. This measurement is done through an ADCP ( Acoustic Doppler current profiler ). What Is The Acoustic Doppler Current Profiler? This device utilizes sound waves to measure the ocean's current speed and direction throughout the water column. This helps in understanding important information regarding the biological, chemical, and physical properties of the ocean. How Does It Work? ADCP utilizes the Doppler effect transmitting sound 'pings.' This effect makes use of a sequence of consistent, rapid pulses that bounces back particles hanging in moving water, reflecting back to the instrument. Fast-moving particles toward the instrument return waves with a higher frequency; however, particles moving away from the instrument pr
