The instrument is fitted with pressure, temperature (SBE-3F) and conductivity (SBE-4C) sensors, three acceleration sensors, a PC104 computer data acquisition and communication system, anti-aliasing filters and a standard suite of microstructure sensors which includes two SPM-38-5 velocity shear probes, two FP07-38-5 fast thermistors and an optional microstructure conductivity probe (SBE7). 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. The VMP 5500 has a strobe light and a radio beacon and can also be fitted with an Argos transmitter for locating purposes. The instrument was replaced by the VMP 6000 in 2010."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0639" ; skos:note "accepted"@en ; skos:prefLabel "Rockland Scientific Vertical Microstructure Profiler (VMP) 5500"@en ; skos:related . skos:narrower . skos:narrower . skos:narrower . skos:narrower . skos:narrower . skos:related .
