3-D seismic interpretation with deep learning: a set of Python tutorials

Thilo Wrona, Indranil Pan, Rebecca Bell, Robert Gawthorpe, Haakon Fossen & Sascha Brune
Here we are sharing our code, tutorials and examples used to interpret geological structures (e.g. faults, salt bodies and horizones) in 2-D and/or 3-D seismic reflection data using deep learning. The repository is organised in a series of tutorials (Jupyter notebooks) with increasing degree of difficulty. We show step-by-step how to: (1) load seismic data, (2) train a model and (3) apply the model to map different geological structures. You can find a few visual...

Stable isotope (2H and 18O) depth profiles of pore waters and inferred soil physical parameters in the Attert catchment, Luxembourg

Matthias Sprenger, Stefan Seeger, Theresa Blume & Markus Weiler
Depth profiles of stable water isotopes in the soil provide important information on flow and transport processes in the subsurface. We sampled depth profiles of stable water isotopes (2H and 18O) in the pore waters on two occasions at 46 sites in the Attert catchment, Luxembourg and are partly located in mixed deciduous forest and partly on grassland. These sites correspond to the sensor cluster sites of the DFG research unit CAOS. Sampling took place...

Analysis of Detections by the Earthquake Network App between 2017-12-15 and 2020-01-31

Robert Steed, Remy Bossu, Francesco Finazzi, István Bondár & Laure Fallou
The 'Earthquake Network’ (EQN) is an app which detects earthquakes by creating an ad-hoc network of smartphones' accelerometer sensors and provides early warnings for earthquakes via the same smartphone app. Detections are not due to individual smartphone measurements but due to near-simultaneous trigger signals from clusters of smartphones running the app. Therefore detections are normally located in the closest populated regions to an earthquake's epicentre. These datasets compare sets of detections with the earthquake parameters...

Reprocessed deep seismic reflection profile DEKORP 1988-9N across the Northern Upper Rhine Graben, Southwest Germany

Benjamin Homuth, Manfred Stiller & Bernd Schmidt
The profile 9N was recorded in 1988 as part of the DEKORP project, the German deep seismic reflection program. The focus of the DEKORP project was on deep crustal and lithospheric structures and therefore originally not on structures at lower depths. From today's perspective, however, this depth range is of great interest for a wide range of possible technical applications (including medium-depth and deep geothermal projects). The original data is published by Stiller et al....

COSC-2 operational report - Operational data sets

Henning Lorenz, Christopher Juhlin, Jan-Erik Rosberg, Mohsen Bazargan, Iwona Klonowska, Jochem Kück, Rodolphe Lescoutre, Simon Rejkjær, George Westmeijer & Grzegorz Ziemniak
The Collisional Orogeny in the Scandinavian Caledonides (COSC) scientific drilling project focuses on mountain building processes in a major mid-Paleozoic orogen in western Scandinavia and its comparison with modern analogues. The transport and emplacement of subduction-related highgrade continent-ocean transition (COT) complexes onto the Baltoscandian platform and their influence on the underlying allochthons and basement is being studied in a section provided by two fully cored 2.5 km deep drill holes. These operational data sets concern...

Nicole Koellner, Agnieszka Kuras, Constantin Hildebrand, Friederike Koerting & Friederike Kaestner
The data set contains LIBS (Laser-Induced Breakdown Spectroscopy) emission spectra of 18 lithium-bearing minerals and their corresponding hyperspectral reflectance spectra. The data were collected within the research project LIGHTS (Lightweight Integrated Ground and Airborne Hyperspectral Topological Solutions, http://lights.univ-lorraine.fr/) which aims at developing a new exploration process for Li targets combining drone-borne hyperspectral data and field observations. Hyperspectral data were acquired with the HySpex system in a wavelength range of 414 - 2498 nm and are...

Back to the lithics: technological comparison of early Upper Palaeolithic assemblages from Al-Ansab/ Jordan, Româneşti-Dumbrăviţa/ Romania and Fumane/ Italy database

Jacopo Gennai
The dissertation addresses the technological variability in the European and Levantine early Upper Palaeolithic (eUP). The eUP is often linked to the major dispersal event of H. sapiens into Europe and the final affirmation of our species into the Eurasian continent over the 43–38 ka cal BP timespan. The main feature is the introduction of bladelets, elongated items less than 12 mm wide, whose production processes are the hallmark for technocomplexes. The principal difference is...

HART-La Palma volcanic eruption

Thomas Walter, Torsten Dahm, Simone Cesca, Carla Valenzuela-Malebran, Claus Milkereit, Nicole Richter, Alina Shevshenko, Daniel Vollmer & Marius Kriegerowski
Following a sequence of seismic events detected by the National Geographic Institute (IGN Spain), on 13.09.2021 the new volcano Cumbre Vieja initiated an eruption, located on the mid-western flank at a location just to the north of the 1949 eruption site. The eruption fed a lava flow that buried already some hundreds of houses, with a high economic estimated loss. Previous studies have shown that La Palma was the source of 3 or 4 large...

Morphological and geo-environmental features of three North Patagonian volcanoe areas (Calbuco, Chaitén, and Huequi) used for hierarchical Bayesian logistic regression for landslide predictions

Eric Parra
The data presented here correspond to a (point) sampling of areas with presence (or not) of landslides from three study areas located in North Patagonia (Calbuco, Huequi and Chaitén). Morphometric and geo-environmental parameter values have been obtained for each sample point. We compiled inventories of landslides that occurred between 2001 and 2019 by mapping from Google Earth® imagery and local ground checks between 2014 and 2019. We mapped landslides using diagnostics such as distinct, elongate,...

UAS-based surface gravelometry for different generations of the coastal alluvial fan Guanillos, Atacama Desert

Janek Walk, Melanie Bartz, Georg Stauch, Helmut Brückner & Frank Lehmkuhl
This dataset contains grain sizes of bright surface clasts extracted digitally from very high resolution aerial imagery for the coastal alluvial fan Guanillos (GUA) in northern Chile (21.97°S, 70.17°W). The largest diameters (a-axes) of bright clasts were derived by global thresholding of RGB orthomosaics (OM) constructed based on surveys using an unmanned aerial system (UAS). Depending on the spatial resolution of the OMs, the minimal detectable grain size is 20 to 22 mm. Restricted to...

Pleiades-1 spectral iron oxide ratios for different surface generations of the coastal alluvial fan Guanillos, Atacama Desert

Janek Walk, Melanie Bartz, Georg Stauch, Helmut Brückner & Frank Lehmkuhl
This dataset contains the spectral ratios between the Red and Blue (R-B) as well as Near Infrared and Blue (NIR-B) bands of 2 m Pleiades-1 (P1) multispectral satellite imagery of the coastal alluvial fan Guanillos (GUA) in northern Chile (21.97°S, 70.17°W). Both spectral ratios are sensitive to iron oxides. Restricted to detailed areas of interest (AOI), the calculated spectral ratios are attributed to the four alluvial fan surface generations, or morphostratigraphic units, Q1 to Q4....
