The effectiveness of recently implemented measures and the state of the Ems are ensured through monitoring. An existing, intensive water management measurement system that has already been used by the state (NLWKN) and the federal government (WSV) on the Ems for many years will be used for this purpose. This system includes, among other things, ten measuring stations that continuously record water quality parameters (salt content, temperature, oxygen content, liquid-silt ratio, depth profile, currents), numerous long-term measurement devices, and measurement campaigns.

The effects of damming for ship crossovers by Meyer Werft on the Ems is accompanied and documented via Monitoring.
