The data represent the calculated yields of wind farms in the exclusive economic zone (EEZ) in full load hours per wind farm expansion area, assuming an expansion of offshore wind energy defined in different scenarios. The calculations were carried out with the numerical weather model WRF using a parameterization of wind farms according to Fitch. The results refer to the areas in the North Sea and the meteorological year 2006. Reports on methodology, scenarios and results are available under the following links: Endbericht: https://www.bsh.de/DE/THEMEN/Offshore/Meeresfachplanung/Flaechenentwicklungsplan/_Anlagen/Downloads/FEP_2023_1/Endbericht_FEP_2023_Beratung.html, Ad-Hoc Analyse FEP Langzeitstatistik kontinuierlicherAusbau: https://www.bsh.de/DE/THEMEN/Offshore/Meeresfachplanung/Flaechenentwicklungsplan/_Anlagen/Downloads/Ad-HocAnalyse_FEP_Langzeitstatistik_kontinuierlicherAusbau.html, Annex zum Begleitgutachten FEP 2023 Revision 1: https://www.bsh.de/DE/THEMEN/Offshore/Meeresfachplanung/Flaechenentwicklungsplan/_Anlagen/Downloads/Annex_Begleitgutachten_FEP2023_Revision1.html, Ad-Hoc Analyse Ertragsmodellierung von Ausbauszenarien: https://www.bsh.de/DE/THEMEN/Offshore/Meeresfachplanung/Flaechenentwicklungsplan_2025/Anlagen/Downloads/Adhoc_Analyse_Ertragsmodellg.html Ad-Hoc Analyse Ertragsmodellierung der Ausbauszenarien 22 und 23: https://www.bsh.de/DE/THEMEN/Offshore/Meeresfachplanung/Flaechenentwicklungsplan_2025/Anlagen/Downloads_Entwurf_FEP/Adhoc_Analyse_Ertragsmodellg_22_23.html, Ad-Hoc Analyse Ertragsmodellierung der Ausbauszenarien 24 und 25: https://www.bsh.de/DE/THEMEN/Offshore/Meeresfachplanung/Flaechenentwicklungsplan_2025/Anlagen/Downloads_FEP2025/Adhoc_Analyse_Ertragsmodellg_24_25.html

The annual survey plan specifies which areas are to be surveyed in the current year.

The data cover the water pollution detected on German territory and in the exclusive economic zone (EEZ). The data include the position, type and sources of water pollution. The data are held for the legal prosecution and punishment of violations of the provisions of the MARPOL Convention 1973/78 in connection with the MARPOL-Owi-Vo, the Helsinki Convention in connection with the 1st and 2nd Baltic Sea Protection Amendment Ordinance and for the processing of individual technical and legal questions of principle regarding the above-mentioned legal provisions and administrative offence law (OWIG i. V. m. StPO and StGB), European law and international law. For more information, please visit: https://gdi.bsh.de/en/data/Water-Pollution_Information_Gewaesserverunreinigungen_DE.pdf

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.

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).
