The instrument includes airfoil shear probes (the shear sensing element comprises a piezo-ceramic bimorph beam which generates an electrical charge in response to cross-axial forces), slow and fast response thermistors, a conductivity cell, two tilt gauges and a pressure gauge. A probe guard mounted at the lower end of the instrument protects sensors from bottom sediments. Data are transmitted back to the ship in real time through a neutrally buoyant line. The FLY series of instruments was developed in the 1980s by the Institute of Ocean Sciences, British Columbia and others, and built by Sy-Tech Research Ltd of Sidney, British Columbia. The instrument is no longer in production."@en ; sdo:inDefinedTermSet ; sdo:name "Fast Light Yo-yo (FLY II) microstructure profiler"@en ; sdo:termCode "SDN:L22::TOOL0428" .
