Different marine data

The BSH collects and processes a multitude of data. These include geospatial data or chemical-physical data of the sea. The BSH distinguishes between data collected by its own resources and data collected by other institutions and transmitted to the BSH for administration. This also includes satellite data.

Data for all

Digitisation enables comprehensive data to be collected and linked from areas that were previously difficult to identify and combine. As a result, the amount of digital data collected during research is constantly increasing. Connecting data is also becoming increasingly complex. A large proportion of thisdata has been collected through costly research cruises or remote sensing and are unique. This includes data from ship-based monitoring, the marine environment monitoring network MARNET, or from the international ARGO programme for the determination of marine environment data.

They all play an important role in data-based basic research. The BSH makes its data available to the public. This includes data series dating back to the 19th century: databases containing oceanographic and chemical data, data for water level prediction models for and data for drift calculations as well as for the production of digital nautical charts.


Numerous databases with specialist information and applications are in operation around the clock. All services and products are based on data collected and cleaned up by the BSH. This data is fed into various databasesand stored there for the long term. Data commissioned by the BSH or made available to the BSH as a national oceanographic data centre is processed in the same way.

The GeoSeaPortal is our central data access portal is. Numerous BSH data are brought together and can be accessed as WebMapServices (WMS). Various data collected at the BSH measuring stations in the North Sea and Baltic Sea are also made available via the marine environment monitoring network MARNET. Individual data areas are offered separately for particularly current data stocks. These include, amongst others, water level and sea state data. You can access this data separately.

A particular challenge is the use and combination of data from different application systems. New principles in maritime developments or incorrect measurements can be determined by analysing all available data. Expert groups at all locations supervise the numerous highly complex specialist applications. They work continuously to ensure uninterrupted networking and utilisation of data in cooperation with other federal and state authorities and institutions.
