ABSTRACT:
An expendable instrument for determining salinity versus depth in a water column and suitable for use from vessels underway, from helicopters, and from fixed platforms. The salinity indication is obtained by the use of a conductivity cell for measuring the water conductivity, and a standard cell for measuring the conductivity of a standard sample, and obtaining the conductivity ratio. The resultant is transmitted up a wire link to processing equipment.
