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).

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.

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.

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).

The data set contains the published status of the spatial designations of the infrastructure area plan as an additional source of information. The planning scale of the plan is 1:400,000. The announced documents are authoritative.

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

The Medium Resolution Imaging Spectrometer (MERIS) on Board ESA’s ENVISAT provides spectral high resolution image data in the visible-near infrared spectral region (412-900 nm) at a spatial resolution of 300 m. For more details on ENVISAT and MERIS see http://envisat.esa.int/ Spectral high resolution measurements allow to assess different water constituents in optically complex case-2 waters (IOCCG, 2000). The main groups of constituents are Chlorophyll, corresponding to living phytoplankton, suspended minerals or sediments and dissolved organic matter. They are characterised by their specific inherent optical properties, in particular scattering and absorption spectra. The Baltic Sea Water Constituents product was developed in a co-operative effort of DLR (Remote Sensing Technology Institute IMF, German Remote Sensing Data Centre DFD), Brockmann Consult (BC) and Baltic Sea Research Institute (IOW) in the frame of the MAPP project (MERIS Application and Regional Products Projects). The data are processed on a regular (daily) basis using ESA standard Level-1 and -2 data as input and producing regional specific value added Level-3 products. The regular data reception is realised at DFD ground station in Neustrelitz.
