The instrument is fitted with pressure, temperature (SBE-3F) and conductivity (SBE-4C) sensors, three high grade accelerometers, an internal data acquisition system with 1 Gb solid state disk (Linux OS), and a standard suite of up to 6 microstructure turbulence sensors in any combination of SPM-38-5 velocity shear probes, FP07-38-5 fast thermistors or optional SBE7 microstructure conductivity probes. There is also a geo-electro magnetic current meter for fine-scale shear measurements. The instrument has an aluminium frame with syntactic foam attached for flotation. Data is collected on the downcast and after reaching a pre-defined depth the profiler releases ballast weights so that the instrument becomes positively buoyant. As back-up there is a triple redundancy emergency ballast release system. The VMP 6000 has an RF beacon, ARGO transmitter and Xenon flasher attached for locating purposes. This instrument replaced the VMP 5500 in 2010."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1150" ; skos:note "accepted"@en ; skos:prefLabel "Rockland Scientific Vertical Microstructure Profiler (VMP) 6000"@en ; skos:related . skos:narrower . dc:isVersionOf .
