Definition of in situ:
In it's original place. From the Latin word situs meaning place.
This is the common definition for in situ, other definitions can be discussed in the article
|
In oceanography this term is mostly used with instruments that measure properties directly in the sea: In situ measurement, in situ sensor, in situ instrument.
Also used to describe the temperature that a water volume has at the depth it is located: In situ temperature.
A related topic are Inline measurements: Sensors or instruments are situated in a flow-through system, e.g., on board a ship, in which water is pumped from the outside. This technique is applied in the FerryBox. The advantages of Inline measurements are:
- The sensors are well protected and therefore have a longer lifetime
- The calibration of the sensors is more stable and the calibration procedure is easier
- Biofouling can easily prevented by applying chemical methods (cleaning).
