During the Quaternary, Rhine Glacier formed several overdeepened valleys, including Tannwald Basin (ICDP site 5068_1, Germany) about 45 km North of Lake Constance. These structures form sedimentary climate archives and thus help to understand dynamics in Alps.To obtain very high-resolution images sediment, seismic crosshole data was acquired using a high-frequency borehole source that predominantly generates SH-waves. The excited meter at 78 143 m depth, wavefield recorded depth 105 134 an...

Abstract. The quality of geothermal carbonate reservoirs is controlled by, for instance, depositional environment, lithology, diagenesis, karstification, fracture networks, and tectonic deformation. Carbonatic rock formations are thus often extremely heterogeneous, reservoir parameters their spatial distribution difficult to predict. Using a 3D seismic dataset combined with well data from Munich, Germany, we demonstrate how comprehensive attribute analysis can significantly improve the...

Robust age-depth models are essential for developing sophisticated interpretations of the sedimentological history in lake basins. In most cases, such created using an integrated geoscientific approach, including biostratigraphy, magnetostratigraphy and radiometric dating. this study, we present approach to construct based on integrating downhole logging seismic survey data when there no samples available An example method is shown from Lake Ohrid (North Macedonia/Albania). First, interpret...

ABSTRACT Over‐deepened basins exist throughout the Alpine realm. Improving our knowledge on these is of high social relevance, since areas are often well‐populated and they possess, for instance, unusual hydrological settings. Nonetheless, geophysical sedimentological investigations over‐deepened rare. We analyse sedimentary succession such a basin, Tannwald Basin, through geological interpretation seismic reflection profiles. The basin located approximately 60 km north European Alps. It was...

The use of intermittent renewable energy sources is great importance for reducing greenhouse gas emissions. Medium-deep borehole thermal storage systems (MD-BTES) represent an economic solution. At the Technical University Darmstadt, Germany, MD-BTES consisting three 750 m deep heat exchangers was constructed as a demonstrator. Before construction, comprehensive dataset electrical conductivity tomography profiles, gravity measurements, 2D seismic and petrophysical data nearby outcrops...

We reveal the subsurface bedrock topography and sedimentary succession of one deepest glacially-formed basins in Eastern Alps: Lienz Basin Upper Drau Valley (Tyrol), by means seismic reflection. A dense source-receiver spacing, supplied autonomous receivers, a prestack depth-migration processing scheme were essential to distinguish various deposits fine detail, such as slumping, fan delta deposits, modified monocline on basin flank. These details support our interpretation stratigraphy that...

Abstract There are many successful geothermal projects that exploit the Upper Jurassic aquifer at 2–3 km depth in German Molasse Basin. However, up to now, only P-wave seismic exploration has been carried out. In an experiment Greater Munich area, we recorded S-waves were generated by conventional survey, using 3C receivers. From this, built a 3D volume of P- S-converted (PS) waves asymptotic conversion point approach. By combining P-volume and resulting PS-seismic volume, able derive...

Several high-frequency seismic sources (i.e., sledgehammer, pipegun, weightdrop, and small- intermediate-size vibrators) have been tested at a site characterized by surface layer of very recent sediments overlying unconsolidated glacial glaciolacustrine units. Reflections from shallow [Formula: see text] to moderate depths were recorded. Evaluation the different involved analyzing prominent features (e.g., reflections signal-generated noise that includes complex patterns interfering direct,...

Abstract The prevailing view suggests that the Eemian interglacial on European Plain was characterized by largely negligible geomorphic activity beyond coastal areas. However, systematic geomorphological studies are sparse. Here we present a detailed reconstruction of to Early Weichselian landscape evolution in vicinity small fingerlake northern margin Salzwedel Palaeolake Lower Saxony (Germany).

In recent years, the sediments filling Pleistocene glacial structures have become of increasing importance to paleoclimate research. Climatic changes are documented by deposition cycles in small, closed, trough or bowl‐like structures. A 2-D, high‐resolution, shallow reflection seismic survey was conducted 1996 over such a structure near Tostedt northern Germany. The objective obtain more accurate picture and underlying geology. Designed especially for surveys, newly developed impulse source...

ABSTRACT Cost reduction in seismic reconnaissance is an issue geothermal exploration and can principally be achieved by sparse acquisition. To address the adherent decrease signal/noise ratio, common‐reflection‐surface method has been proposed. We reduced data density of existing 3D dataset evaluated results processing using attributes. The application leads all cases to improvement ratio. most distinct seen low fold regions. depends strongly on midpoint aperture, there a tradeoff between...

Reflection seismic imaging using horizontally-polarized S-waves (SH) can increase resolution and it could be cost-efficient compared to the common use of P-waves. However, since S-wave application often delivers varying data quality, appropriate processing schemes are required for particular interpretation purposes. In this paper, we present four tailored strategies that applied SH-wave acquired in an overdeepened Quaternary basin Alpine foreland, Tannwald Basin. The consist (1) a short...

Very shallow seismic surveys, i.e. 20–100 m target depth, require a large bandwidth of high frequencies to ensure detailed resolution. A survey with small hydraulic vibrator across young glacial structures in northern Germany that gave unsatisfactory results was repeated monitored motions.

During the Quaternary, glaciers shaped Alpine region by excavating deep valleys and refilling them with sediments that they transported. One such overdeepened valley is Tannwald Basin (ICDP site 5068_1), which was created Rhine Glacier in what thought to have been several glaciations. The found thus provide climate archives tell us about landscape evolution if we understand sedimentation processes took place.To study these glacial terms of their small-scale structure deposition, acquired P-...
