Demands for integrity, transparency and reproducibility of today's research are increasing, posing new challenges for research data and software management in all science communities. The geoscience community is responding to these requests with a growing number of scientific networks and strategic initiatives, at different levels and with varying thrust. Clearly, publicly funded geoscience research data and software will increasingly be part and parcel of these frameworks: among them national efforts such as the German National...

Earth's surface is subject to a complex interplay of tectonic, atmospheric, and biologic forcing and processes of chemical and physical weathering and erosion. In turn, surface processes can modulate climate, tectonics, and life by the cycling of sediments, water, nutrients, and carbon. Predicting the sensitivity of the Earth's surface to changes in climatic or tectonic forcing, therefore requires an understanding of individual processes as well as their interactions across spatial and temporal scales. Here we...

To weather rock, reagents are required. For example, CO2 is found in rainwater as carbonic acid or CO2 is produced by plant roots and by microbes. Through the large fractures carbonic acid and CO2 reach great depth – dissolved in water. Through the fine fractures they reach the interior of the rock. There they dissolve minerals, like the feldspar. New, completely different minerals form, for example clay minerals. They create fine fractures through which water...

In response to the growing geo-societal challenges of our densely populated planet, current research frequently requires convergence of multiple research disciplines, and optimized use of openly available data, research facilities and funds. Especially the Earth and environmental sciences play a significant role in addressing these challenges, but require the integration of scientific data, software and tools from multiple, globally distributed resources to unlock their full potential to contribute. In addition, the number of Earth and...

Gravity measurements contain important information about the subsurface at every spatial scale. Satellite missions provide highly accurate, global measurements, that allow building and testing 3D models of the Earth even for regions where other geophysical measurements are sparse. Depending on the envisaged model resolution and application, gravity data from regional or local surveys (e.g. ship and airborne) can be incorporated to provide higher resolution. However, solutions to the gravity inverse problem are non-unique and constraints...

This session addresses the dynamics of sedimentary basins at different temporal and spatial scales and aims to bring together a wide range of studies focusing on geodynamics, tectonics and sediment dynamics. Contributions addressing major processes affecting the genesis and evolution of basins are in particular encouraged (from rifting and overlying passive continental margins to orogenic, intra-montane and extensional back-arcs in convergent settings). A wide range of studies are encouraged, aimed at understanding the evolution of...

The PESO array provides two weeks of local seismological observation in the vicinity of the IPOC (Plate Boundary Observatory Network Northern Chile) station Patache (CX.PATCX) to investigate the subsurface structure and the ambient seismic field. Waveform data is available from the GEOFON data centre, under network code 7F, and is fully open.

The classical way to model the stress state in a rock volume is to estimate displacement boundary conditions that minimize the deviation of the modelled stress state with respect to model-independent stress information such as stress magnitude data. However, these data records are usually subject to significant uncertainties and measurement errors. Hence, it has to be expected that not all stress magnitude data records are representative and can be used in a model. In order...

While the use of nuclear energy is set to be phased out in Germany by mid-April 2023, the management of high-level radioactive material remains a long-term task that will also concern future generations. With the Site Selection Act (StandAG), legislators have defined the regulatory framework for the site selection procedure currently under way for a deep geological repository in Germany. The aim of the procedure is to ensure the greatest possible safety for a period...

During weathering of the deep rocks, many actors act together. This is a property characteristic of the entire “Earth system”. For example, fractures open up, through which water flows that carries carbon and reagants with it from above. New minerals are formed and open up further fractures. Large fractures are also a gateway for microbes from above. They multiply at depths where there is carbon and iron is oxidised. The explorer Alexander von Humboldt stated...

Weathering of rock needs water. A rock fractured by tectonic movement is gradually eroded from above, and it moves closer towards the Earth's surface. There it is exposed to precipitation and water begins to penetrate the soil and the layers beneath the soil. Through the tectonic fractures, the water can reach great depths. This is a rapid transport process. At a millimetre scale the water slowly moves into the interior along the smallest cracks that...

Weathering needs fractures in the rock. When two tectonic plates collide, the plates slide against each other. During earthquakes fractures in the rock are created. The microscope reveals tiny cracks running through the rock. These micro-fractures are caused by the movement of the rocks against each other, but also when erosion at the Earth's surface removes the burden of the overlying rock. Fractures are necessary to bring water, reagents, and microbes to depth to weather...

The interaction of fluid and rock, and the properties of pores and their connectivity are among the main controls on the production and storage potential in clastic and carbonate rocks. At least as much as in the hydrocarbon sector, the exploration of geothermal resources or storage sites for CO2 or hydrogen, require knowledge of processes on the pore scale. Compaction, cementation, dissolution, and alteration, control the evolution of reservoir quality and are also key to...

In contrast to traditional point-like seismometers, Distributed Accoustic Sensing (DAS) can probe the seismic wavefield along a one-dimensional trajectory at unprecedented spatial density over very long arc lengths and at very high temporal sampling rates. From onshore hydrocarbon exploration the technology has spread into numerous other applications ranging from vertical seismic profiling over onshore and offshore seismic monitoring to exploration and site characterization in dense urban agglomerations using dark telecommunication fibers. As telecommunication grids are...

The Mallik Anticline is a geologic structure in the Mackenzie Delta in the Canadian Arctic. Tectonics throughout the Cenozoic, with compressional phases in the early Eocene to the late Miocene, formed this large, domed structure that is today an important source of hydrocarbons. Gas hydrates occur in the clastic sedimentary rocks of the Oligocene to Pleistocene Kugmallite, Mackenzie Bay, and Iperk sequences, which were essentially formed by deltaic processes. The presence of hydrocarbon gases within...
