For information about the CTD-rosette equipment package as a whole, see: Rosette sampler

A CTD or Sonde is an oceanography instrument used to measure the conductivity, temperature, and pressure of seawater (the D stands for "depth," which is closely related to pressure). The reason to measure conductivity is that it can be used to determine the salinity.
The CTD may be incorporated into an array of Niskin bottles referred to as a carousel or rosette. The sampling bottles close at predefined depths, triggered either manually or by a computer, and the water samples may subsequently be analyzed further for biological and chemical parameters.
The CTD may also be used for the calibration of sensors.
