  • The present Single Beam Echosounder Data were recorded within the framework of the hydrographic survey of the Federal Maritime and Hydrographic Agency, but were not subjected to any further quality assurance or validation. Please note that these data sets are raw data.

  • Obstruction data for nautical products. For more information, please visit:

  • This metadata set describes the CSW interface of the metadata catalogue of the spatial data infrastructure of the Federal Maritime and Hydrographic Agency (GDI-BSH).

  • Data maritime boundaries for nautical products. For more information, please visit:

  • The map service "Magnetic Variation" offered for the information system "Geomagnetic Information" shows position-related magnetic variation data with the name of the nautical chart for which the respective magnetic variation value was calculated. The magnetic variation information is available for the current year and additionally for the following year and 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.

  • TMAP parameter group: Counts of migratory birds (MIGB). Counts of Migratory Birds in the Wadden Sea The trilateral Monitoring and Assessment Program was established in 1994 and contains 28 chemical, biological, geological and common parameter. Analyses enable an assessment on the trilateral agreed ecological targets. Results are published as Quality status report regularly. Investigations are done with regard to the following issues of concern primarily (Kellermann, A. et al. 1994): - Effects of climate change on the morphology, - Effects of pollutant inputs (nutrients and contaminants) on processes, species and communities, - Effects of fisheries on species and communities, - Effects of recreational activities on species, - Effects of agricultural utilization on salt marsh communities. TMAP Parameter Gruppe: Counts of migratory birds (MIGB). Counts of Migratory Birds in the Wadden Sea Das 1994 zum Schutz des Wattenmeeres eingeführte Trilateral Monitoring and Assessment Program (TMAP, deutsch: Trilaterales Monitoring und Bewertungsprogramm) umfasst ein Monitoring von insgesamt 28 chemischen, biologischen, geologischen und allgemeinen Parametern. Eine Auswertung der Monitoringdaten ermöglicht eine Beurteilung des Zustandes im Wattenmeer vor dem Hintergrund der trilateral vereinbarten ökologischen Entwicklungsziele. Die Ergebnisse werden etwa alle fünf Jahre im Qualitätszustandsbericht veröffentlicht. Dabei stehen Erhebungen zu folgenden Komplexen im Vordergrund (Kellermann, A. et al. 1994): - Folgen möglicher Klimaänderungen auf Hydrologie, Morphologie und Habitate des Wattenmeeres, - Auswirkungen von Nähr- und Schadstoffeinträgen auf geochemische und biologische Prozesse sowie auf Arten und Lebensgemeinschaften des Wattenmeeres, - den Auswirkungen der Muschel- und Garnelenfischerei auf Arten und Lebensgemeinschaften, - Auswirkungen von Freizeitaktivitäten auf Arten (vor allem Vögel und marine Säuger) sowie - Auswirkungen landwirtschaftlicher Nutzung auf die Lebensgemeinschaften der Salzwiesen.

  • The data set contains the tidal current data for certain positions in the German Bight. The information is based on a tidal current simulation using the BSH circulation model BSHcmod V4. For more information, please visit:

  • Description: Spatial distribution of selected macrozoobenthic 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: 1997 to 2011, mainly spring and autumn data (EIA data), but also summer and winter data (AWI data) Sampling standards: Data of EIAs follow the standard investigation concept StUK 1-3 (BSH 2007), AWI data collected in accordance with the ICES sampling standard (Rumohr 1999). Sampling gears: mainly van Veen grabs (0.1 square metre, 30-95 kg), few stations by box corer (0.1 square metre, 160 kg), Nephrops norvegicus and Goneplax rhomboides sampled by beam trawl and dredge (1-3 m width) Sampling: 1-3 replicates per station, fixation in 4 % buffered formalin seawater solution, dredge and beam-trawl data recorded on board or subsamples frozen stored, abundance and biomass (g wet weight) per species Data analysis: science information system of benthic invertebrate data, examination of quality and plausibility, data harmonisation, product computation by AWI Product description: Grid: 5x5 km² for grab data, 10x10 square kilometre for data on N. norvegicus and G. rhomboides from beam trawl and dredge hauls; available selectable parameter: number of stations, minimum, maximum, mean, median and standard deviation of density (m-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! Rumohr, H. (1999). "Soft bottom macrofauna: Collection, treatment, and quality assurance of samples."
