POTENTIAL TEMPERATURE  

Definition

  • Measurement of water temperature taking water's compressibility into account, provided no heat exchange of the water sample with its surroundings. This is important because water temperature is higher under the higher pressure conditions of the deep ocean compared to the temperature of that same water at the lower pressure conditions of the ocean surface.
