CO2 storage potential of the Jurassic within the German Central Graben

Within the framework of the GEOSTOR Project, the CO2 storage potential of the Jurassic succession in the German Central Graben was analysed. Twelve potential trap structures were initially mapped along the base of the Kimmeridge Clay Formation, which serves as the primary seal for potential reservoir sandstones within the Central Graben Subgroup. The Kimmeridge Clay Formation is generally continuously distributed across the German Central Graben, with only localized penetrations by rising salt diapirs. In contrast, the Central Graben Subgroup, serving as a potential reservoir unit, exhibits an uneven distribution across the area, limiting the presence and continuity of reservoir rocks within each trap structure. To further delineate the spatial extent of the mapped reservoir structures, the base of the Central Graben Subgroup was used as an additional reference layer. Due to the intermittent nature of Jurassic sandstones within the Central Graben Subgroup, a subsequent analysis classified each structure based on borehole data to confirm the presence of reservoir sands. Structures were categorized as ‘proven,’ ‘not present,’ or ‘uncertain’ depending on sandstone availability and continuity within the trap. All mapped reservoir structures are buried at depths ranging from 2225 to 3043 meters (apex depth) and are considered closed systems, situated within a complex structural network of salt diapirs, faults, and pinch-outs. Capacity calculations were conducted following the method outlined by Fuhrmann et al. (2024), and the horizons used for mapping are based on the work of Müller et al. (2023) and Thöle et al. (2021).

INSPIRE: Information system salt structures: planning basis, selection criteria and estimation of the potential for the construction of salt caverns for the storage of renewable energies (hydrogen and compressed air) (InSpEE) (WMS)

The WMS InSpEE (INSPIRE) provides information about the areal distribution of salt structures (salt domes and salt pillows) in Northern Germany. Contours of the salt structures can be displayed at horizontal cross-sections at four different depths up to a maximum depth of 2000 m below NN. The geodata have resulted from a BMWi-funded research project “InSpEE” running from the year 2012 to 2015. The acronym stands for "Information system salt structures: planning basis, selection criteria and estimation of the potential for the construction of salt caverns for the storage of renewable energies (hydrogen and compressed air)”. Taking into account the fact that this work was undertaken at a scale for providing an overview and not for investigation of single structures, the scale of display is limited to a minimum of 1:300.000. Additionally four horizontal cross-section maps display the stratigraphical situation at a given depth. In concurrence of maps at different depths areal bedding conditions can be determined, e.g. to generally assess and interpret the spread of different stratigraphic units. Clearly visible are extent and shape of the salt structures within their regional context at the different depths, with extent and boundary of the salt structures having been the main focus of the project. Four horizontal cross-section maps covering the whole onshore area of Northern Germany have been developed at a scale of 1:500.000. The maps cover the depths of -500, -1000, -1500, -2000 m below NN. The four depths are based on typical depth requirements of existing salt caverns in Northern Germany, mainly related to hydrocarbon storage. The shapes of the structures show rudimentary information of their geometry and their change with depths. In addition they form the starting point for rock mechanical calculations necessary for the planning and construction of salt caverns for storage as well as for assessing storage potentials. The maps can be used as a pre-selection tool for subsurface uses. It can also be used to assess coverage and extension of salt structures. Offshore areas were not treated within the project. All horizontal cross-section maps were adjusted with the respective state geological survey organisations. According to the Data Specification on Geology (D2.8.II.4_v3.0) the WMS InSpEE (INSPIRE) provides INSPIRE-compliant data. The WMS InSpEE (INSPIRE) contains two group layers: The first group layer “INSPIRE: Salt structures in Northern Germany“ comprises the layers GE.Geologic.Unit.Salt structure types, GE.GeologicUnit.Salt pillow remnants, GE.GeologicUnit.Structure-building salinar and GE.GeologicUnit.Structural outlines. The layer GE.GeologicUnit.Structural outlines contains according to the four depths four sublayers, e.g. GE.GeologiUnit.Structural outlines 500 m below NN. The second group layer „INSPIRE: Horizontal cross-section maps of Northern Germany“ comprises according to the four depths four layers, e.g. Horizontal cross-section map – 500 m below NN. This layer, in turns, contains two sublayers: GE.GeologicFault.Relevant fault traces and GE.GeologicUnit.Stratigraphic Units. Via the getFeatureInfo request the user obtains additional information on the different geometries. In case of the GE.Geologic.Unit.Salt structure types the user gets access to a data sheet with additional information and further reading in German for the respective salt structure via the getFeatureInfo request.

Deep OCean Test ARray DOCTAR (OBS part)

This is the first deployment of a teleseismic broadband array consisting of 12 three-component stations with an aperture of about 50 km in the deep ocean in about 5000 m water depth. The data can be compared with two other deployments on Madeira and in western Portugal mainland which had similar array layouts and recording time spans (network Y7). The broadband data enable furthermore analysis of the crust and upper mantle beneath the array near to the Gloria fault, a major transform fault in the North Atlantic. Recordings of numerous local and regional earthquakes make a precise location of active structures possible. Waveform data is available from the GEOFON data centre, under network code 3J.

Entwicklung von Umweltqualitaetszielen fuer die regionale und kommunale Planung

Eine umfassende, auch wertorientierte Wahrnehmung der Umwelt ist ohne Umweltqualitaetsziele nicht moeglich. Blosse Gefahrenabwehr oder Sanierung kommen notfalls noch ohne weiterfuehrende Vorstellungen ueber eine Umwelt, in der nachhaltig die Umweltvertraeglichkeit der Raumstrukturen und -funktionen und die Lebensqualitaet der Menschen gewaehrleistet wird, aus. Dagegen bedarf eine Umweltvorsorge, bei der weitere schaedigende und belastende Umwelteinfluesse nicht nur verhindert, sondern die vorhandene Umwelt auch verbessert werden soll, raeumlich, zeitlich und sachlich differenzierter Umweltqualitaetsziele. Diese werden als regional differenzierte Stes erarbeitet und der Entwicklungsprozess prototypisch aufbereitet. Mit den gewonnenen Ergebnissen, die auch ueber Datenbanken verfuegbar sein werden, koennen Staedte und Gemeinden den Einsatz dieses Instrumentes beschleunigen und versachlichen.

The scalar organization of environmental governance: an institutionalist perspective on the transformation of water and marine governance in the European Union

The project aims to theorize the scalar organization of natural resource governance in the European Union. This research agenda is inspired by critical geographers' work on the politics of scale. The research will examine an analytical framework derived from theories of institutional change and multi-level govern-ance to fill this theoretical gap. Furthermore, it will review conceptualizations of the state in institutional economics, evaluate their adequacy to capture the role of the state in the dynamics identified, and develop them further. The described processes may imply shifts in administrative levels, shifts in relations between different levels and changes in spatial delimitations of competent jurisdictions that result, for example, from decentralization or the introduction of river basin oriented administrative structures. The research investigates the implications of two European Directives: the Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). They both have potentially great significance for the organization of marine and water governance at the level of Member States and below, and adhere to similar regulatory ideas for achieving good ecological status of waters. A multiple case study on changes in the scalar reorganization of marine and water governance that result from the implementation of the Directives will be carried out. It will rely on qualitative and quantitative data gathering based on semi-structured interviews and review of secondary and tertiary sources looking at Portugal, Spain, and Germany. It specifically addresses the role of social ecological transactions, the structure of decision making processes and the role of changes in contextual factors (such as ideologies, interdependent institutions and technology).
