The data set comprises all MSRL-relevant parameters measured by stations of the Federal Maritime and Hydrographic Agency (BSH).

For the calculation of the data "AIS Vessel Density", the data of the Universal Shipborne Automatic Identification System (AIS) were evaluated with regard to various parameters and ship types under stochastic aspects. The data are requested once a year for the past year from the European Maritime Safety Agency (EMSA). Among others, the information is collected and stored for the purpose of securing maritime traffic and is used for the manufacture of products produced for navigation by the Federal Maritime and Hydrographic Agency (BSH). The data "AIS Vessel Density" represent the mean spatial density distribution of the ships. The mean spatial ship density is the current number of ships that could be expected in a defined area (grid cell) at any time during a reference period under consideration. The counting distinguishes between five types of vessels: fishing vessels, cargo vessels, tankers, passenger vessels and all vessels.

Among others, the information is collected and stored for the purpose of securing maritime traffic and is used for the manufacture of products produced for navigation by the Federal Maritime and Hydrographic Agency (BSH). The data "AIS Vessel Traffic Density" represent the mean spatio-temporal density distribution of the ships. This is the average number of ships that have passed through a defined area (grid cell) in a certain period of time. The counting distinguishes between five types of vessels: fishing vessels, cargo vessels, tankers, passenger vessels and all vessels.

After the end of World War II, about 40 000 t of chemical warfare munitions were dumped in the Baltic Sea under the direction of the Allies. Between 1994 and 1997, the BSH, in cooperation with the Institute for Baltic Sea Research (Warnemünde) and the German Navy, conducted numerous investigations in which the transport routes in the area of the German continental shelf were examined for metal bodies using geophysical measuring methods and an underwater video camera. The IMS (Internet Map Service) processes and bundles the results of the investigations and makes them available.

The map service "Magnetic Variation" offered for the information system "Geomagnetic Information" shows position-related magnetic variation data with the name of the nautical chart for which the respective magnetic variation value was calculated. The magnetic variation information is available for the current year and additionally for the following year and based on the World Magnetic Model (WMM) valid at the time of display. In addition, areas of uncertain declination mapped for the German coastal area, i.e. areas where the declination of the earth's magnetic field deviates significantly from its normal value.
