  • Satellite Image of Albedo in Baltic Sea

  • The map service "Magnetic Variation Lines" offered for the technical information system "Geomagnetic Information" shows lines of the same declination (isogons) for most of Europe and adjacent areas. The isogons are based on the World Magnetic Model (WMM) and are calculated in advance for the current year. Land contours are not part of the service.

  • 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).

  • Data of the Nautical Hydrographic Information System. This includes the floating and fixed navigation marks, as well as further information on navigation in the sea and land area [of the German area of the Exclusive Economic Zone (EEZ)].

  • hourly tidal currents (related to high water Heligoland) of the North Sea in a horizontal resolution of 3 nautical miles.

  • 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.

  • The data cover 12 to 36 hours predictions as result of the BSH circulation model. resolution about 1 nautical mile (E-W 100'', N-S 60'') on a spharical grid. 3D-parameters (except wind, waterlevel and ice) have been computed for vertical levels with lower limits (meter) of 8, 16, 24, 50, 100, 150, 200, 250, 1000.
