It features higher power and an increased signal-to-noise ratio compared with the standard (300 m depth rated) Aquadopp so that it can provide accurate current measurements in water with low concentrations of suspended particulate matter. Current velocity is derived from the Doppler shift measured by two or three 2MHz acoustic beams. It comes with compass, tilt, pressure and temperature sensors. It has a titanium casing rated to 6000 m and data are stored on an internal logger. It can be run in 'diagnostic' mode when set to collect data at 1 Hz frequency in user specified intervals, which allows studies of mooring motion and the performance of other current meters to be conducted."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0476" ; skos:note "accepted"@en ; skos:prefLabel "Nortek Aquadopp 6000 3D Doppler current meter"@en ; skos:related .
