TeGeRam - Fibre optic temperature measurement in water bodie

The project TeGeRam deals with the development of a measurement prototype for highly accurate spatial and temporal temperature determination in water bodies by means of fibre-optic monitoring systems using Raman spectroscopy. The prototype of a new type of fibre-optic temperature measurement system will be developed for both flowing and standing waters.  Since the fibre-optic cable, used for the measurement, collects data over the entire length, the system promises great value compared to conventional measurement methods, which work with point measurements. The depth profiles over long distances in flowing waters as well as the water column in standing waters can thus be collected in a time-efficient and thus much more cost-effective way compared to previous methods. High-resolution temperature profiles can then be derived from the data and statements about the water quality of a water body.
