The Quasi-Other as a Sobject

Larissa Ullmann
This comment on Mark Coeckelbergh’s text “You, robot: on the linguistic construction of artificial others” is about the concrete use of linguistic terms to describe the technical other, the robot, and its relationship to humans. There are many characteristics that a robot can have that are very similar to humans and interpersonal relations, but they are not human, they are quasi-human. This phenomenon is, amongst others, constructed and interpreted linguistically, but on the other hand,...

Experiences gained in the frame of the project “Darmstadt_3D”, which is delivering the urban subsurface including the technical infrastructure (sewage system, foundations, etc.), now are adopted for a working area...

Reconstruction of Miocene geodynamics in the Central Alps using detrital garnet geochemistry in sandstones of the Swiss foreland basin

Daniela Krieg & Laura Stutenbecker
The geodynamics in the Central Alps during the Miocene were majorly characterized by the exhumation of crystalline basement, the so-called external crystalline massifs. Their exhumation had a major impact on the evolution of relief, distribution of drainage networks and sediment-generation. The timing of their first surficial exposure and their total thickness still remains debated. The Swiss Molasse Basin contains ~35 to 13 Ma old clastic deposits that were mostly derived from the immediate hinterland and...

Perceived environmental barriers and facilitators of refugee children’s physical activity in/around refugee accommodation: a qualitative case study in Berlin

Siqi Chen & Martin Knöll
Abstract Background Previous research have identified built environmental attributes associated with refugee children’s physical activity (PA); however, there is a lack of research focusing on refugee children’s environmental perceptions at the individual level. We examined the perceived environmental barriers and facilitators of refugee children’s PA. Methods Perceptions of PA environments by refugee children (n = 15, 6 to 13 years old) and their parents (n = 10) were captured by questionnaires and drawing workshops from...

Tectonic and environmental perturbations at the Permian-Triassic boundary: insights from the Blue Nile River Basin in central Ethiopia

Maryam Mansouri , Matthias Hinderer , Laura Stutenbecker , Guido Meinhold , Enkurie L. Dawit , Jasper Berndt & Robert Bussert
The Blue Nile River Basin contains a thick fluvio-lacustrine sediment succession of Permian to Jurassic age. Its evolution is linked to extensional tectonics during break-up of Pangea in the aftermath of the Carboniferous-Permian glaciation. We collected sandstone samples from several sections in order to study the tectonic evolution and possible impacts of environmental perturbation around the Permian-Triassic boundary. Based on thin-section petrography, bulk-rock geochemistry, heavy mineral spectra, and detrital zircon U-Pb ages we are able...

3D Basin modelling of the northern Upper Rhine Graben : insights on geothermal fluid pathways

Gillian Bethune , Adriana Lemgruber-Traby , Claire Bossennec , Kristian Bär , Jeroen van der Vaart , Christine Souque & Renaud Divies
The area of the Upper Rhine Graben (URG) is known for its geothermal potential. However, the recent interest for lithium co-production from geothermal brines raises questions about the quantification and dynamics of fluid flow paths in the geothermal system at the basin scale. This study aims to better understand the impact of the fluid circulation on the temperature field evolution and on the fluid recharge by performing a 3D thermal basin modeling. The Buntsandstein group...

Gravity survey in delineating geologic features of interest for deep geothermal use at Campus North of KIT.

Maximiliano Pavez , Natalia Cornejo , Florian Bauer & Eva Schill
The seasonal mismatch of the thermal energy demand can be addressed by thermal energy storage systems of high capacity (e.g. Lee 2013). In this scenario, High-temperatures aquifer thermal energy storage systems (HT-ATES), which commonly supply domestic needs could expand to meet heating or industrial processes demands by storing excess heat. DeepStor is a planned scientific infrastructure that address the demonstration the concept of HT-ATES in former hydrocarbon reservoirs of deep sedimentary rocks. Specifically, the concept...

Transition from hydrocarbon production to geothermal heat storage in the Upper Rhine Graben – the DeepStor project

Eva Schill , Jens Grimmer , Katharina Schätzler , Kai Stricker , Judith Bremer & Thomas Kohl
The subsurface conditions of the Upper Rhine Graben are favorable for the development of novel geothermal utilization concepts. In particular, they allow optimization of energy use with flexible heat production and storage scenarios. A first potential analysis revealed an enormous storage potential of formerly used and well-explored oil fields. The involvement of former hydrocarbon reservoirs as components of geothermal concepts perfectly symbolizes the transition from the fossil-fuel age to the use of carbon-neutral renewable energies....

Granulometric and lithologic control on apatite and zircon concentrations in Alpine fluvial sediment

Daniela Krieg, Laura Stutenbecker , Ariane Djahansouzi & Christoph Glotzbach
Detrital heavy mineral compositions are controlled by many factors such as mineral fertility in the source rocks and hydraulic sorting. Quantifying and understanding the resulting bias is crucial especially for the correct interpretation of single-grain analyses such as apatite or zircon geochronology in provenance studies. In this study, an inter- and intrasample comparison of apatite and zircon concentrations is conducted on modern Alpine fluvial sands from five mono-lithological catchments draining granitoid, ophiolitic, metamorphic and sedimentary...

Light at the end of the well: A compact and low-cost DIY water level meter

Nils Michelsen
Goundwater level data are a crucial element of water resources assessments. Corresponding measurements are often carried out with electric water level tapes, which are – despite their simple concept – relatively expensive. Here, I present a low-cost alternative, consisting of an ordinary measuring tape and an off-the-shelf “LED bait” (actually used for fishing). The latter is simply attached to the tape with a binder clip and starts flashing upon water contact. At reasonable depth-to-water conditions...

Data from: Stochasticity leads to coexistence of generalists and specialists in assembling mutualistic communities

Lara Becker, Nico Blüthgen & Barbara Drossel
Previous models for assembling ecological networks did not include stochasticity at the level of population dynamics (e.g., demographic noise, environmental noise) and focused mainly on food webs. Here, we present a model for the assembly of mutualistic bipartite networks, such as plant-pollinator networks, and examine the influence of demographic noise on the trajectory of species and strategy diversity, i.e., the range of present strategies from specialism to generalism. We find that assembled communities show at...

Stefanie Kaboth-Bahr , André Bahr , Olaf Lenz , Volker Wilde , Sonja Wedmann & Jörg Pross
The late early to early middle Eocene (~48 Ma) maar lake sediments of the famous Messel fossil-pit, located near Darmstadt, SW Germany, represent a prime archive for climate dynamics operating during the geologically most recent greenhouse period of the Earth. In this study, we investigate the potential of geochemical data obtained via high-resolution XRF core scanning to decipher hydrologic variability from the Messel sediments. Such data have the potential to yield insight into the paleoenvironmental...

The impact of hydrothermal alteration on the physiochemical characteristics of reservoir rocks: the case of the Los Humeros geothermal field (Mexico)

Leandra M. Weydt, Federico Lucci, Alicja Lacinska, Dirk Scheuvens, Gerardo Carrasco-Núñez, Guido Giordano, Christopher A. Rochelle, Stefanie Schmidt, Kristian Bär & Ingo Sass
Abstract Hydrothermal alteration is a common process in active geothermal systems and can significantly change the physiochemical properties of rocks. To improve reservoir assessment and modeling of high-temperature geothermal resources linked to active volcanic settings, a detailed understanding of the reservoir is needed. The Los Humeros Volcanic Complex, hosting the third largest exploited geothermal field in Mexico, represents a natural laboratory to investigate the impact of hydrothermal processes on the rock properties through andesitic reservoir...

Slip tendency analysis for 60 3D faults in Germany and adjacent areas

Luisa Röckel , Steffen Ahlers , Birgit Müller , Karsten Reiter , Oliver Heidbach , Tobias Hergert , Andreas Henk & Frank Schilling
Tectonic faults are of great importance for many underground applications such as hydrocarbon extraction, geothermal operations or nuclear waste repositories. In particular, the fault reactivation potential is crucial in regards of safety and efficiency of these applications. Major influences on the reactivation potential are the contemporary tectonic stress field and changes to it due to anthropogenic activities. One measure of the reactivation potential of faults is the ratio of resolved shear stresses to normal stresses...

Arthropod (per year, 2008-2017) and environmental data (climate, land use, land cover) from grasslands used in \"Unravelling insect declines: can space replace time?\", Biology Letters

Michael Staab & Nico Blüthgen
To compare trends in arthropod species numbers between space and time, arthropod data from the sweep net samples (2008-2017) in grasslands were used. We tested whether trends over time are also found within single years (i.e. in space). The dataset contains, pooled per sampling year, arthropod individual numbers (Araneae, Coleoptera, Hemiptera, Orthoptera) and associated environmental data (climate, land use, land cover). This data is only to complement the publication "Unravelling insect declines: can space replace...
