Zusammenfassung:	A measuring system measures temperature distribution in water using an optical fiber. An optical fiber cable suspended from a ship and towed by the ship to form an arch within the water. A measuring device for continuously measuring temperature at various points along the lengths of said optical fiber cable. Sensors are provided within the water to calculate the water depth at each of the various points along the length of the arch shaped optical fiber. Thus, a temperature distribution at each water depth can be continuously measured.
