The "Magnetic Variation" map service offered for the specialist information system "Geomagnetic Information" shows lines of the same declination (isogons) and lines of the same annual change in declination for the greater part of Europe and adjacent areas as well as position-related declination data with naming of the nautical chart for which the respective declination value was calculated. The lines of the same declination and the same annual change are displayed for the current year and the position-related declination data are additionally displayed for the following year. All information on dismissals is based on the World Magnetic Model (WMM) valid at the time of presentation. In addition, areas of uncertain declination are mapped for the German coastal area, i.e. areas in which the declination of the earth's magnetic field deviates considerably 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).

Data on wave heights from North Sea, Baltic Sea, North Atlantic and Mediterranean Sea
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.
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.
