Marine Environmental Database
Welcome to the Marine Environmental Database (MUDAB)


mission
In 1994, the federal government and the states concluded an administrative agreement on the exchange of data in the environmental sector. On this basis, the coastal federal states and other federal and research institutions transfer their marine monitoring data to the Marine Environmental Database (MUDAB).
The Federal Institute of Hydrology operates the marine environment database on behalf of the Federal Environment Agency. The MUDAB application on the Internet makes the available, quality-assured measurement data from federal and state institutions accessible to the public.

Networking
The MUDAB records physical, hydrographic, hydrochemical and biological parameters of the marine environment. The central database supports the activities of the Federal/State Working Group on the North and Baltic Seas (BLANO), among other things. In addition, the MUDAB makes a significant contribution to the international commitments made by Germany to provide environmental data for marine protection. Among other things, the marine environment database provides the measurement data to support the international “Oslo/Paris Convention on the Monitoring of the North Sea” (OSPAR) and the “Helsinki Convention on the Monitoring of the Baltic Sea” (HELCOM). Last but not least, the MUDAB makes a significant contribution to the “Marine Environmental Reporting” (SOE Report) to the European Environment Agency in Copenhagen (EEA).

monitoring of the oceans
The monitoring stations of the Federal-State Measurement Program (BLMP) are managed in the MUDAB station editor. These monitoring stations are known by name and location and are therefore identifiable up to the international level.
These stations are called "project stations" in the MUDAB and are operated by the respective state or federal authorities as well as research institutions. The stations are often marked in the sea by a buoy.
A ship cannot always get right up to the buoy on its journey, but must stay at a certain distance and take measurements. The position of the ship is stored and thus forms the so-called measuring station. This is then assigned to the nearby project station in the MUDAB.
Welcome on board
The project stations are visited at regular intervals as part of the federal-state measurement program to take samples. A ship sets off at a specific time, visits several project stations and returns to port. This period is called a voyage and the data is always submitted to the MUDAB for a complete voyage. If data for a voyage is to be added at a later date, the entire voyage must be updated in the MUDAB.
