Karst aquifers constitute important freshwater resources, but are challenging to manage and to protect, because of their unique hydraulic structure and behaviour, representing continuous challenges for research and development. Karst aquifers are widespread and contribute to freshwater supply of most Mediterranean countries and many cities are supplied by karst water, e.g., Rome, Vienna, Montpellier and Beirut. These land surfaces correspond to the main recharge zones of karst aquifers, which are often hydraulically connected over large areas and are highly vulnerable to contamination. The preparation of the Mediterranean Karst Aquifer Map (MEDKAM) generally followed the workflow used for the World Karst Aquifer Map (WOKAM). A new lithological classification has been developed for the MEDKAM, similar to that of the WOKAM, which groups the geological units into four meaningful hydrogeological units: 1). Karst aquifers in sedimentary and metamorphic carbonate rocks. 2). Karst aquifers in evaporite rocks. 3). Various hydrogeological settings in other sedimentary and volcanic formations (karst aquifers are possibly present at depth). 4). Local, poor and shallow aquifers in other metamorphic rocks and igneous rocks (no karst aquifers present at depth).

The General Geological Map of the Federal Republic of Germany 1:200,000 (GÜK200) provides detailed information on the stratigraphy, petrography and genesis of the geological units shown. In this revised GÜK200-DN, the onshore surface geology is shown in up to two overlays. The thin overlying soil is not shown. In the marine environment, only the petrography of the recent seabed is shown, which comprises the uppermost 20 cm of the seabed. In accordance with the original GÜK200 map sheets, the seabed is referred to stratigraphically as the recent seabed. According to the Data Specification on Geology (D2.8.II.4_v3.0) the geological map provides INSPIRE-compliant data. A base layer and two overlay layers are displayed correspondingly to the INSPIRE portrayal rules. The geologic units are represented graphically by stratigraphy (GE.GeologicUnit.BaseLayer.AgeOfRocks, GE.GeologicUnit.OverlayLayer1.AgeOfRocks, and GE.GeologicUnit.OverlayLayer2.AgeOfRocks) and lithology (GE.GeologicUnit.BaseLayer.Lithology, GE.GeologicUnit.OverlayLayer1.Lithology, and GE.GeologicUnit.OverlayLayer2.Lithology). The user obtains detailed information via the getFeatureInfo request on the lithology, stratigraphy (age) and genesis (event environment and event process).

Storage of CO2 in deep geological formations is one possibility of reducing CO2 emissions from industry that are difficult to avoid. High-quality geological models and capacity estimates are crucial for the successful planning and implementation of safe storage projects. This study analyses the storage potential of the Middle Buntssandstein (Lower Triassic) and Lower to Middle Jurassic within the Exclusive Economic Zone (EEZ) of the German North Sea.

The web service of the dataset comprises the locations of outcrops with respective information on the lithology, stratigraphy, rock age and tectonic data collected during the CASE expeditions. The data attributes include stereographic projections and sketches of tectonic structures derived from the outcrop data. At the end of the 1980s, BGR initiated the research program Circum-Arctic Structural Events (CASE) to reconstruct the plate tectonic processes during the evolution of the Arctic Ocean using terrestrial data from the surrounding continental margins. One of the scientific questions of the CASE programme is as simple as it is complex: How did the Arctic Ocean, this large basin between the Eurasian and North American continental plates, develop? There are still no conclusive answers to this question in terms of plate tectonics. In contrast to the marine expeditions of geophysicists in the Arctic Ocean, geologists on land along the various coastal areas of the Arctic Ocean can directly touch, examine and map rocks, structures, folds and fault zones and determine the respective ages of the movements. This makes it possible to directly compare rock units and deformation zones on different continental plates and thus also to reconstruct when these plates collided, how long they remained next to each other and when and how they separated again. Since the inception of BGR’s Arctic research, the primary focus and research areas have been along the continental margins between Spitsbergen and the Canadian Arctic Archipelago via Greenland, to the Yukon North Slope on the border with Alaska. On the opposite side of the Arctic Ocean, there have been expeditions to Yakutia, the mainland areas near the Laptev Sea, the New Siberian Islands and to the Polar Ural with Russian partners. An important method for the interpretation of the geological evolution of the Arctic is the examination of tectonic structures (faults, folds, cleavage etc.), the determination of the kinematics and the age of the tectonic movements.

Web Map Service (WMS) of the BUEK1000. The first country wide soil map at a scale of 1:1,000,000 (BUEK1000) has been compiled on the basis of published soil maps of the former German Democratic Republic and the pre 1990 federal states of Germany. To do this, it was necessary to match the soil systems used in East and West Germany and to develop standardized descriptions of soil units. A relatively homogeneous map has resulted, which permits uniform assessment of the soils throughout Germany. The map shows 71 soil mapping units, described in the legend on the basis of the German and FAO soil systems. Each soil unit has been assigned a characteristic soil profile (Leitprofil) as an aid to map interpretation. For the first time the subdivision of the country into 12 soil regions has been represented on the map. This subdivision was coordinated with the state Geological Surveys. These soil regions will represent the highest hierarchic level of nation wide soil maps in future. The colours of soil units correspond to the standards of the 'Bodenkundliche Kartieranleitung' (KA 3; Guidelines for Soil Mapping). The various hues characterize differences in relief or soil humidity. The BUEK1000 was produced digitally. It is an important part of the spatial database integrated in the Soil Information System currently being established at the Federal Institute for Geosciences and Natural Resources (FISBo BGR). It can be used together with the characteristic soil profiles to derive thematic maps related to nation wide soil protection. The scale of the BUEK1000 makes it especially suitable for small scale evaluations at federal or EU level.

The “Geological Map of Germany 1:1,000,000 OneGeology-Europe (GK1000-1GE)” shows Germany’s surface geology: All geological units are described by their age (stratigraphy) and composition (lithology). The geological units and terms used in this map were semantically harmonized within the OneGeology-Europe project and have been - in a number of regions - geometrically and semantically made consistent with the neighbouring OneGeology-Europe participants.

In this paper, we present the results of a large-scale numerical model of a generic nuclear waste repository situated in an argillaceous host rock formation. Modelling the evolution of an entire repository presents challenges due to the strong contrast in spatial and temporal scales at which the different processes take place, ranging from the centimetres to the kilometres and days to hundreds of thousands of years, respectively. From the view point of the physical processes, a further challenge originates from the different gas transport mechanisms: Gas advection as well as gas dissolution and diffusion jointly govern the efflux of gas from the repository and mitigate excess pore pressures, but there is a significant contrast between the rates of these two transport mechanisms. Using the TH2M implementation in the open-source finite element code OpenGeoSys-6 , we analyse the impact of gas transport via advection (in the partially saturated zones such as backfilled drifts, shafts and desaturated host rock) as well as gas transport via diffusion (in fully water-saturated media such as the undisturbed host rock and over- and underlying formations). Finally, this work outlines and discusses possible simplifications in modelling choices, such as mechanical surrogate models, geometrical simplifications as well as the impact of discretization. The work presented in this paper was carried out within the scope of the European Joint Programme EURAD, workpackage Gas, Task 4.
