  • As part of the joint federal / Länder measurement program for the North and Baltic Seas, the parameter "chlorophyll-a in sea water" was determined in seawater.

  • Data on administrative boundaries, existing and planned uses as well as planning area definitions from the field of maritime spatial planning within the Exclusive Economic Zone of Germany (EEZ). This data is provided by Continental Shelf Information Systems (CONTIS).

  • 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.

  • Meteorological and oceanographical data of the North and Baltic Sea, North Atlantic and Mediterranean Sea.

  • The record includes global land areas and coastal lines. It is based on the freely available data base GSHHS (A Global Self-consistent, hierarchical, high-resolution Shoreline Database) from Wessel and Smith. GSHHS is a high-resolution record of coastal paths, by merging two data sets from the "public domain". The original records were extensive edited by the GSHHS originators, and are now internally consistent and free of maverick points and intersecting lines. The coast lines are completely closed to polygons. According to the original data set are 5 stages of resolution made available: crude, low, medium, high, and full resolution. In the German coastal area, the coastal courses of the highest level of resolution are exchanced through accurate ECDIS ENC data of the BSH.

  • Meteorological and oceanographical data of the North and Baltic Sea, North Atlantic and Mediterranean Sea.

  • Timeseries of turbidity data obtained from the MARNET network. The MARNET network comprises of 11 stations in the North Sea and in the Baltic Sea

  • For the calculation of the data "AIS Vessel Traffic 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 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.

  • Timeseries of directional spreading of wave data obtained from the MARNET network.

  • The weekly ice maps are produced from the data of the ice observations in the North Sea and Baltic Sea. Further information is available at: https://gdiwiki.bsh.de/wiki/index.php/Ice_Chart
