  • INSPIRE theme Maritime Units. These are condensed coordinates of the sea border maps 2920 (North Sea) and 2921 (Baltic Sea). They are (interpolated) coordinates compressed to geodetic lines. The distance between the nodes on the geodetic lines connecting the defined border points is less than or equal to 100 m. The sea borders of Germany were proclaimed in the coordinate system European Datum 1950 (ED50), which is no longer used today. The basis for this determination is in particular the promulgation of the proclamation of the Federal Government on the expansion of the German territorial sea of 19 October 1994 (Federal Law Gazette I p. 3428) and the proclamation of the Federal Republic of Germany on the establishment of an exclusive economic zone of 25 November 1994 (Federal Law Gazette II p. 3769), which are decisive with regard to the delimitation of the German territorial sea and the German exclusive economic zone. In order to make better use of these boundaries in today's geoinformation systems and to avoid conversion errors, the BSH has derived the present utility coordinates in WGS 84. In this respect they are not official maritime borders of Germany.

  • DTM of the German Bight (yearly, 1982 - 2012). Classified isosurfaces of spatiotemporally interpolated bathymetries from the years 1982 to 2012, with two parameters for the purposes of reliability: Confidence and Minimum dt. The parameter Confidence [m] indicates the reliability of the modelled bathymetry. Data were generated within the framework of the German Coastal Engineering Research Council project AufMod ("Aufbau integrierter Modellsysteme zur Analyse der langfristigen Morphodynamik in der Deutschen Bucht" ["Development of integrated model systems for the analysis of long-term morphodynamics in the German Bight"], 01.11.2009-31.12.2012).

  • A large number of offshore projects are planned and implemented in the German Exclusive Economic Zone or on the continental shelf. These include wind farm projects, the connection of wind farms to the power grid by means of so-called grid connection systems, the construction and laying of other submarine cables and pipelines, the installation of measuring points and finally the performance of research activities.

  • Spatial and temporal distribution of noise emissions due to pile driving during the foundation of wind turbines in offshore projects in the German Exclusive Economic Zone EEZ. Source of data: MarinEARS Noise Registry (Marine Explorer and Registry of Sound); visit https://marinears.bsh.de Description of data: Start and end date of the construction phase with noise emissions due to pile driving during the foundation of wind turbines, per area of offshore wind farm visualized by coloration.

  • 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.

  • 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 Lines" offered for the technical information system "Geomagnetic Information" shows lines of the same declination (isogons) for most of Europe and adjacent areas. The isogons are based on the World Magnetic Model (WMM) and are calculated in advance for the current year. Land contours are not part of the service.
