The data set comprises parameters influenced by eutrophication which are recorded at measuring stations of the Federal Maritime Office and Hydrography. Parameters: Chlorophyll a, nutrient concentrations, visibility depth, macrophytes, oxygen content, oxygen saturation index and nitrogen loads from the river basin districts.
Data of the skin of the earth of the Nautical Hydrographic Information System (NAUTHIS).
In order to support the implementation of the European Water Framework Directive (EU-WFD), the German State Geological Surveys (SGD) and the Federal Institute for Geosciences and Natural Resources (BGR) agreed in 2000 to compile a digital hydrogeological map at the scale of 1:200,000 (HÜK200), providing a harmonised survey of the upper groundwater bodies in Germany. The HÜK200 captures hydrogeologically relevant attributes such as consolidation, type of porosity, permeability, type of rock and geochemical classification to describe the hydrogeological characteristics of the rocks of the uppermost aquifers. The geological information on lithology, stratigraphy and genesis of the geological map of Germany 1:200,000 (GÜK200) provided the basic data. This information was evaluated and hydrogeologically interpreted by regional experts of the SGD or replaced and completed by other regional geological and hydrogeological maps and data where necessary. 2019, HÜK200 was migrated to a scale of 1:250.000 (now HÜK250).
The map layers are based on the BGR geoscientific collection and display geocoded localities of the object types fossile, mineral and rocks. In three zooming levels according to administrative district, community and local subdistrict the total number of samples for the chosen area are shown. A direct connection between the map layer and the GewiS-application (https://gewis. bgr.de) is possible.
The exchange frequency of water in soils describes how often water and the dissolved substances in it can be replaced in a soil layer during the annual leachate flow. Small water storage capacity means high replacement frequency. The risk of the discharge of easily detachable materials like nitrate is given at high exchange rates.

The relief of the earth's surface is a major controlling factor for ecological processes and a key indicator of the distribution patterns of important geological factors such as soil, rock and water. On the basis of a digital elevation model with a grid size of 250 meters, the company scilands GmbH in Göttingen produced on behalf of BGR the geomorphographic map of Germany. The programs SARA (System for Automatic Terrain Analysis) and SADO (System for Analysis and Discretization of Surfaces) determined 25 discrete geomorphograpic units (sink areas, closed hollow forms, slope areas, parietal areas, overlay forms) in four different landscape areas (North German Lowland, highland, Alpine foothills and Alps).
Web Map Service (WMS) of BUEK200 series. The soil map 1:200,000 (BUEK200) is prepared by the Federal Institute for Geosciences and Natural Resources (BGR) in cooperation with the National Geological Surveys (SGD) of the federal states in the sheet line system of the Topographic Map 1:200,000 (TUEK200) and is published in 55 individual map sheets. The digital data management provides a detailed, nationwide uniform and comprehensive information base for statements on land use and soil protection across the states. The soil inventories and their spatial distribution on the territory of each map sheet is currently described in terms of legend units structured by soil regions and landscapes. Each legend unit contains soil systematic information as well as information about the soil parent material of each dominant and associated soil.
This dataset has been compiled within the BGR project "D-AERO-Auswertung" based on several survey area located along the German North Sea coast. The BGR helicopter (Sikorsky S-76B) is used for airborne geophysical surveying of the Earth’s subsurface. The standard equipment comprises the methods electromagnetics, magnetics and radiometrics. The passive magnetic (HMG) system consists of two Cesium magnetometers, which are located in the HEM flying tube (bird) about 40 m beneath the helicopter as well as in a base station on ground. The results are displayed as maps of the anomalies of the Earth's magnetic total field.
GEMAS (Geochemical Mapping of Agricultural and Grazing Land Soil in Europe) is a cooperative project between the Geochemistry Expert Group of EuroGeoSurveys and Eurometeaux. In total, more than 60 international organisations and institutions worldwide were involved in the implementation of the project. During 2008 and 2009, a total of 2219 samples of agricultural (arable land soils, 0 – 20 cm, Ap samples) and 2127 samples of grazing land (pasture land soils, 0 – 10 cm, Gr samples) soil were collected at a density of 1 site/2 500 km² each from 33 European countries, covering an area of 5,600,000 km². In addition to the chemical element contents, soil properties and soil parameters such as pH, particle size distribution, effective cation exchange capacity (CEC), MIR spectra and magnetic susceptibility were investigated in the samples and some coefficients were calculated. The WMS presents the areal distribution of the determined parameters and coefficients in the shape of colour shaded contour maps.
