SMO 1 - ADCP - QC dataset

Metadata

Instrument: Teledyne RDI WorkHorse Sentinel ADCP 600 kHz
Investigator: Beatrice Giambenedetti (INGV)
Project: SMO
Observatory: NEMO-SN1

Citation: Giambenedetti, Beatrice. (2012). ADCP dataset (RDI WorkHorse 600 KHz @ 2 profile / hour) from INGV/NEMO-SN1 seafloor platform during SMO project in Western Ionian Sea site (East Sicily), part of EMSO network.

Abstract: 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. The ADCP operates using three transducers generating beams with different orientations relative to the water flow then the measured velocity by each ADCP transducer is the projection of the 3D velocity onto the axis of its acoustic beam.

Purpose:

Quality of data: The QC version of the datasets has been elaborated verifying sensor efficiency through post-calibration and standardized validation procedures. More information about QC procedures are contained in the download file
