The Federal Network Agency (BNetzA) has determined the addressee and the amount of support under the Renewable Energy Sources Act (EEG) by means of a call for tenders since 2021 onwards for wind turbines at sea that are commissioned from January 1, 2026 onwards. With the amended Offshore Wind Energy Act (WindSeeG), which came into force on January 1, 2023, there is a change in the tendering process for centrally pre-surveyed areas to bidding criteria that are newly defined in sec. 51 WindSeeG. The location, timing and sequence of the areas to be tendered are determined in each case by the Site Development Plan (FEP). The sites defined in the FEP are examined by the Federal Maritime and Hydrographic Agency (BSH) in accordance with sec. 9 et seqq. WindSeeG. The preliminary site investigation comprises studies on the marine environment (sec. 10 para. 1 no. 1 WindSeeG), the preliminary investigation of the subsoil (sec. 10 para. 1 no. 2 WindSeeG), the investigation of the wind and oceanographic conditions on the area to be tendered (sec. 10 para. 1 no. 3 WindSeeG) as well as necessary studies on shipping to identify hazards to the safety and ease of traffic from the installation and operation of offshore wind turbines (sec. 10 para. 1 no. 4 WindSeeG). The results of the investigations and related documents are made available via the data hub. The provision serves the fulfillment of the legal obligation from sec. 50 sen. 2 no. 7 WindSeeG.

In the world's oceans, underwater sound (hydro-sound) is generated by natural sources such as wind, waves, sea ice and animals. But humans also generate additional sound sources through their activities on and in the sea. The Federal Maritime and Hydrographic Agency (BSH) maintains Germany's national noise register as part of the implementation of the Marine Strategy Framework Directive (MSRL). We collect information and measurements on impulsive sound events (pile driving, detonations, military activities, seismic and other impulsive sound events) as well as continuous sound measurements from the German North and Baltic Seas.

The ”Water Recreation” app provides interested users with information on water levels, water and air temperatures, and wind strength and direction, enabling them to plan their activities on and in the water.

The “Marine Information” application provides various marine and meteorological information for water level locations on the Weser, Elbe,Ems, North Sea, and Baltic Sea. For each water level location, users can view information about the water level, water surface temperature, air temperature, wind speed and direction, and the times of sunrise and sunset and moonrise and moonset. The data is updated at least once a day, depending on availability and type.

Marine Forecast is an internet application that provides current data and information from the meteorological and oceanographic field. The data are current measurement and forecast data on different topics, which can be combined in different ways.
