ADCP dataset with Quality Control (RDI WorkHorse 300 kHz @ 1 sample / hour) from INGV/GEOSTAR - SN-3 seafloor platform during ORION-GEOSTAR3 project in Southern Tyrrhenian Sea site (Marsili Basin), ORION1 Campaign

The Acoustic Doppler Current Profiler measures the water velocity using the physical Doppler shift principle. The transducer generates a pulse of sound at a known frequency that travels through the water and is reflected in all directions by particulate matter (e.g., sediment, biological matter, bubbles). Some portion of the reflected energy travels back at the transducer where the processing electronics measure the change in frequency. The Doppler shift measured by the transducer reflects the velocity of the water along the axis of the acoustic beam.
This Quality Controlled (QC) version of the datasets has been elaborated verifying sensor efficiency through post-calibration and standardized validation procedures. More information about QC procedures is contained in the download file.
