The dataset 'Coastline - Baltic Sea' contains the water-land boundary of the German federal territory in the area of the Baltic Sea. Survey data, orthophotos and map material were used to create the coastline.

This Web Service provides, inter alia, data from approval and enforcement procedures of the German Federal Maritime and Hydrographic Agency (BSH) within the Exclusive Economic Zone (EEZ). The data quality may vary due to the age and the variety of sources used. Thus, no guarantee is given for the correctness of the data.

Description: Spatial distribution of selected demersal fish species in the German Bight. Data source: Data from environmental impact assessments (EIA) under the permit procedures of the Federal Maritime and Hydrographic Agency (BSH) in the North Sea EEZ and research data of the Alfred Wegener Institute (AWI), Helmholtz Centre for Polar and Marine Research; time period: 2000 to 2014, mainly spring and autumn data (EIA data), but also summer and winder data (AWI data) Sampling standards: Data of EIAs follow the standard investigation concept StUK 1-3 (BSH 2007), AWI data mainly collected in accordance with the ICES sampling standard (Rumohr 1999). Sampling gears: EIA-data with 7-8 m (partly 6 m) beam trawl (haul: 15 min), AWI-data with a 2-3 m beam trawl (haul: 5-15 min); trawling speed 3-4 kn, codend mesh size 10 mm Sampling: 1 haul per station and sampling date, data were recorded on board or subsamples were stored frozen for further analysis, analysis of abundance and biomass (kg wet weight) per species Data analysis: science information system of demersal fish data, examination of quality and plausibility, data harmonisation, product computation by AWI Product description: Grid: 10x10 km²; available selectable parameter: number of stations, minimum, maximum, mean, median and standard deviation of density (km-²) per species; classification method: natural jenks (Jenks Caspall algorithm); Note: The products contain a different classification of species density! Note: Please regard different value ranges! Note: Data refer exclusively to demersal fish species spectrum! Cited literature Rumohr, H. (1999).

Obstruction data for nautical products.

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 Traffic 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.

The service provides the magnetic variation data for nautical charts. The magnetic declination information 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.

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.
