| Definition | A free-falling instrument designed to measure temperature, salinity and turbulent shear from near surface to within 15cm of the seabed. 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 FLY IV used the same sensors as the FLY II but incorporated more advanced electronics and software. Data transmission was achieved via the TELUS Mobility Network. The instrument is no longer in production. | ||
