"An Acoustic Doppler Current Profiler (ADCP) for use in in ocean circulation, turbulence, numerical model verification and transport studies. The instrument consists of three piezo-composite transducers which are 25 cm in diameter. The beams operate at long-range (1000 m) and in dual-frequency (55 / 75 kHz) modes. The instrument contains integrated pressure and temperature sensors measuring in the range of 0-1500m (pressure) and -4 - 40 degC (temperature). Data communication is available via Ethernet cable and the instrument has an internal storage capacity of 16 Gb, with an option to increase this to 64 Gb."@en . . . . . . . . .
