Calculation of thermal conductivity of low-porous igneous rocks from modal mineralogy

Sven Fuchs, Hans-Jürgen Förster, Kathleen Braune & Andrea Förster
This data set compiles the raw data that were used to calculate the bulk thermal conductivity (λb) of low-porosity igneous rocks from modal mineralogy, porosity, and nature of saturation fluid. It compliments a paper by Fuchs et al. (2018) to which it represents supplementary material. The paper reports the result of seeking out the mixing model(s) providing the best match between measured (λb.meas) and calculated bulk thermal conductivity (λb.calc) for low-porous igneous rocks. The study...

GeoMultiSens developed an integrated processing pipeline to support the analysis of homogenized data from various remote sensing archives. The processing pipeline has five main components: (1) visual assessment of remote sensing Earth observations, (2) homogenization of selected Earth observation, (3) efficient data management with XtreemFS, (4) Python-based parallel processing and analysis algorithms implemented in a Flink cloud environment, and (5) visual exploration of the results. GeoMultiSens currently supports the classification of land-cover for Europe.

Data supplement to: Laser ablation in situ silicon stable isotope analysis of phytoliths

Daniel A. Frick, Jan A. Schuessler, Michael Sommer & Friedhelm Von Blanckenburg
Silicon is a beneficial element for many plants, and is deposited in plant tissue as amorphous bio-opal (phytoliths). The biochemical processes of uptake and precipitation induce isotope fractionation: the mass-dependent shift in the relative abundances of the stable isotopes of silicon. At the bulk scale, the silicon isotope composition reported as δ30Si span from -2 to +6 ‰. To further constrain these variations, at the scale of individual phytolith fragments we applied in situ femtosecond...

This dataset is related to the master's thesis "Distribution modeling of paleofauna in the Western Mediterranean between the Heinrich events H5 and H4". The aim of the work was to generate a model for species distribution in the Western Mediterranean and to determine the best method in this context. By applying three different methods (Bioclim, GLM, MaxEnt) from the dismo package, R was used to predict the distribution of eight cold-adapted prey species in the...

A global database of radiogenic Nd and Sr isotopes in marine and terrestrial samples

Cécile L. Blanchet
The database presented here contains radiogenic neodymium and strontium isotope ratios measured on both terrestrial and marine sediments. It was compiled to help assessing sediment provenance and transport processes for various time intervals. This can be achieved by either mapping sediment isotopic signature and/or fingerprinting source areas using statistical tools (see supplemental references). The database has been built by incorporating data from the literature and the SedDB database and harmonizing the metadata, especially units and...

Matlab Script FAST Calibration v1.0

Moritz O. Ziegler
The 3D geomechanical-numerical modelling of the in-situ stress state requires observed stress information at reference locations within the model area to be compared to the modelled stress state. This comparison of stress states and the ensuing adaptation of the displacement boundary conditions provide a best fit stress state in the entire model region that is based on the available stress information. This process is also referred to as calibration. Depending on the amount of available...

Supplementary paleomagnetic data to: “Paleomagnetism in the Pannonian; Problems, Pitfalls, and Progress in using iron sulphides for magnetostratigraphy”

Nick A. Kelder, Karin Sant, Gijs A. Van Dijk, Ymke Z. Lathouwers, Mark J. Dekkers, Wout Krijgsman, Imre Magyar & Orsolya Sztanó
This dataset contains the paleomagnetic supplementary material to the article Kelder et al. (subm.), which presents a magnetostratigraphic correlation of Late Miocene lacustrine sediments based on multi-polarity greigite. The multi-polarity is visible in most thermal paleomagnetic results (Zijderveld diagrams) by antipodal high and medium temperature components, while only one magnetic component was visible in the alternating field demagnetization diagrams. Based on this complex behavior, a tailored demagnetization approach was developed to allow for reliable magnetostratigraphic...

Frank Lehmkuhl, Janina Bösken, Jan Hošek, Tobias Sprafke, Slobodan B. Marković, Igor Obreht, Ulrich Hambach, Pál Sümegi, Arne Thiemann, Stefanie Steffens, Heiko Lindner, Daniel Veres & Christian Zeeden
This set of data depicts the distribution of loess and related Quaternary sediments in the Carpathian Basin. Using a Geographic Information System (GIS), we compiled a map showing the distribution of loess and related Quaternary sediments in the Carpathian Basin, with unprecedented detail. We vectorized and analyzed existing data (mainly from geological maps) and combined and transferred these into a common (loess) sediment classification system. This cross-border map shows the distribution of eolian sediments in...

gms-index-mediator: a R-tree-based in-memory index for fast spatio-temporal queries for the GeoMultiSens platform

Daniel Eggert, Mike Sips & Doris Dransch
Gms-index-mediator is a standalone index for spatio-temporal data acting as a mediator between an application and a database. Even modern databases need several minutes to execute a spatio-temporal query to huge tables containing several million entries. Our index-mediator speeds the execution of such queries up by several magnitues, resulting in response times around 100ms. This version is tailored towards the GeoMultiSens database, but can be adapted to work with custom table layouts with reasonable effort.
