The CTD measures conductivity, temperature, and depth. It contains a temperature sensor and a conductivity sensor. It is capable of obtaining real-time data. The CTD is connected to an onboard computer and can process data into graphical displays. A large number of seawater parameters including salinity, density, and sound velocity can be computed from CTD data. These photographs were taken from the RV Cape Hatteras.
