These stations were installed by the German Research Centre for Geosciences (GFZ) in Potsdam, Germany in close cooperation with the Central-Asian Institute for Applied Geosciences (CAIAG) in Bishkek, Kyrgyzstan, the national hydrometeorological services in Uzbekistan and Tajikistan, the Ulugh Beg Astronomical Institute in Tashkent, Uzbekistan, and the Kabul...

Continuous monitoring of soil CO2 efflux and atmospheric parameters at the Los Humeros Volcanic Complex

Anna Jentsch, Walter Duesing, Egbert Jolie & Martin Zimmer
Carbon dioxide is the most abundant, non-condensable gas in volcanic systems, released into the atmosphere through either diffuse or advective fluid flow. The emission of substantial amounts of CO2 at Earth’s surface is not only controlled by volcanic plumes during periods of eruptive activity or fumaroles, but also by soil degassing along permeable structures in the subsurface. Monitoring of these processes is of utmost importance for volcanic hazard analyses, and is also relevant for managing...

Experimental data for permeability and stiffness measurements of fractured Flechtingen sandstone measured with a triaxial compression apparatus

Christian Kluge, Guido Blöcher, Hannes Hofmann, Auke Barnhoorn, Jean Schmittbuhl & David Bruhn
Faults and fractures form the largest contrast of fluid flow in the subsurface, while their permeability is highly affected by effective pressure changes. In this experimental study, fractured low-permeability Flechtingen (Rotliegend) sandstones were cyclically loaded in a MTS tri-axial compression cell. Two different loading scenarios were considered: “continuous cyclic loading” (CCL) and “progressive cyclic loading” (PCL). During continuous cyclic loading, a displaced tensile fracture was loaded hydrostatically from 2 to 60 MPa in several repeated...

We present a compilation and analysis of 1099 Holocene relative shore-level (RSL) indicators including 867 relative sea-level data points and 232 data points from the Ancylus Lake and the following transitional phase from 10.7 to 8.5 ka BP located around the Baltic Sea. The spatial distribution covers the Baltic Sea and near-coastal areas fairly well, but some gaps remain mainly in Sweden. RSL data follow the standardized HOLSEA format and, thus, are ready for spatially...

Seismic Velocity Model of Crust and Upper Mantle beneath South Central Andes including Pampean and Payenia

Yajian Gao & Frederik Tilmann
A new seismic model for crust and upper mantle of the south Central Andes is derived from full waveform inversion, covering the Pampean flat subduction and adjacent Payenia steep subduction segments. Focused crustal low‐velocity anomalies indicate partial melts in the Payenia segment along the volcanic arc, whereas weaker low‐velocity anomalies covering a wide zone in the Pampean segment are interpreted as remnant partial melts. Thinning and tearing of the flat Nazca slab is inferred from...

WeTeDe - Well Test Deconvolution

Leonard Grabow & Michael Kühn
The aim of this software is to assess the influence of water well production rates to the measured water level data dependent on the reservoir properties. Daily abstraction rates can be used for this production rate well test analysis. For the analysis, a modified deconvolution algorithm is implemented in the code. The algorithm derives the reservoir response function by solving a least square problem with the unique feature of imposing only implicit constraints on the...

(2018)). The filtered spherical harmonic coefficients are accompanied by their variance-covariance matrices which are gained via variance propagation from the variance-covariance matrices of the unfiltered...

The Brazilian geoid model MAPGEO2004 is limited by 7°N and 35°S in latitude and 34°W and 75°W in longitude with 10' resolution. Fast Fourier Transform (FFT) technique was used to undertake the modified Stokes integral. The mean Helmert anomalies in 10'x10' grid was obtained from the existing terrestrial gravity data (IBGE, several institutions in Brazil and neighboring countries in continental area) until 2004. The free air anomalies of the KMS99 model was used in oceanic...

RST Evaluation - Scripts for analysing shear experiments from the Schulze RST.pc01 ring shear tester

Michael Rudolf & Michael Warsitzka
The software RST Evaluation is a series of scripts to semi-automatically evaluate shear experiments done at the Helmholtz Laboratory for Tectonic Modelling. In principle, it may be used for other measurements done in a similar setup, but it was build with our standardized workflow in mind. The shear experiments are done in a ring shear type shear cell rst.pc01 manufactured by D. Schulze (Details in ASTM standard D-6773). It uses an easy and reproducible workflow...

Dataset on laboratory pilot-scale simulations: CH4-CO2 exchange in gas hydrate-bearing sediments within GFZ´s Large Reservoir Simulator (LARS)

Katja Heeschen, Christian Deusner, Erik Spangenberg, Mike Priegnitz & Judith M. Schicks
The guest molecule exchange of methane (CH4) by carbon dioxide (CO2) in natural gas hydrate reservoirs is considered a desirable possibility to produce CH4 and at the same time sequester CO2. So far process evaluation is commonly based on CH4-CO2 exchange yields and rates from small- or medium-scale experiments in partly water-saturated sediments, both of which does not represent natural conditions. The experiments are presented in detail in a currently submitted manuscript by Heeschen et...
