Abstract

Dynamic response calibrations have been made for temperature and conductivity probes produced by Sea- Bird Electronics. These probes are used on wire-lowered and towed conductivity, temperature, and depth systems (CTDs) as well as on free-fall oceanographic profilers. The response of the conductivity cell was measured for free-flow and pumped configurations. Legendre polynomials have been fitted to the measured transfer functions to provide analytic farina for data correction.
