Technical data and evaluation data from (central) preliminary investigation of sites

Data from (central) preliminary investigation of sites are available in the PINTA data portal of the Federal Maritime and Hydrographic Agency (BSH):

• PINTA data portal for (central) preliminary investigation of sites

Data from non-central preliminary investigation of sites are available in the continuously updated list of Technical data and evaluation data from profiling and mapping geological surveys (see above), as soon as the legal publication regulations permit.

Geological data from investigations in the German EEZ

According to Chapter 4 of the Geological Data Act (GeolDG), geological data must be made available to the public. All data can be downloaded from the BGR Geoportal. The download services will be continuously expanded in line with the progress in the data preparation in accordance with the GeolDG.

• List of publicly available geological data according to GeolD

Data from decades of North Sea exploration archived at BGR often exist only in analogue form. Scanning and digitization of this data is an ongoing multi-year effort. Data for downloads is regularly updated and expanded.

If the required data is presently not available, we recommend trying to verify availability again at a later date. Parts of the analogue inventory may also be accessed locally at the BGR archive.

Please note that public access to some data might be limited due to the statutory regulations for data categories defined by the Geological Data Act (GeolDG) (see FAQ – German language only).

BGR does not guarantee the completeness, timeliness or accuracy of the data provided.

BGR bears no responsibility with regard to the timeliness, completeness and accuracy of data submitted under the Geological Data Act (GeolDG). The data are made publicly available in the form in which they were provided by the party obliged to transmit them under the GeolDG. A plausibility check can only be carried out on a random basis. Liability for illegal, incomplete or incorrect content is excluded. Should you be of the opinion that the data violates applicable law, please inform us. An immediate check and, if necessary, deletion or deactivation will take place.

If you are planning to use the data within the scope of commercial activity note that by conducting geological investigations in the sense of § 3 para. 2 of the GeolDG you are required to adhere to these points below:

• Two weeks before the start of the investigation at the latest, an official notification (Anzeige) of the metadata (Nachweisdaten) in accordance with § 8 GeolDG must be made to the responsible authority (to BGR); this also applies to the reprocessing of data;
• The technical data (Fachdaten) that is obtained from the investigations must be transmitted (to BGR) no later than three months after completion of the investigation in accordance with § 9 GeolDG
• No later than six months after completion, the evaluation data (Bewertungsdaten) must be transmitted in accordance with § 10 para. 1 GeolDG or, must be transmitted (to BGR) on request in accordance with § 10 para. 2 and 3 GeolDG.
