NOAA Photo Library Image - ship4367

Figure 69. Expendable bathythermograph made by Sippican Corporation. These instruments pay out a copper wire upon descent that has varying conductivity as the temperature changes. Depth is determined as a function of the rate of descent of the instrument. These are used by ships while underway to determine the temperature profile of the water column and corresponding velocity profile.
