Current meter dataset (Nobska MAVS-3 @ 2 Hz) from INGV/NEMO-SN1 seafloor platform during SMO project in Western Ionian Sea site (East Sicily), part of EMSO network

This sensor performs water current measures in a three axial reference system. Flow velocity and direction is measured by observing the time-of-arrival difference of sound along the acoustic paths. It has also a compass in order to measure the earth's magnetic field, and a tilt sensor to measure the instrument's angle. Using these measurements, the direction of the instrument can be determined and consequently the flow direction.
