Data supplement to \"A Study in Blue: Secondary Copper-rich Minerals and their Associated Bacterial Diversity in Icelandic Lava Tubes\"

Nina Kopacz
Lava tubes on Earth represent some of the most enticing Martian analogue environments when investigating the possibility of past or present life on Mars. Lava tubes provide stable, sheltered environments, isolated and protected from the radiation on the surface. The microbial mats in these caves further regulate the environment for life, allowing various microbial communities with different metabolisms to coexist. This adaptation is so successful, one could imagine such a microbe-mineral continuum might occur on...

European Sustainable Workforce Survey - Full

Tanja Van der Lippe
A sustainable European workforce has become increasingly relevant in our present day and age. Flexibility and job insecurity are omnipresent; organizational workforces are displaying growing diversity with respect to age, gender, ethnicity and family status; and Europe’s welfare states are delegating more and more responsibility for the well-being of workers to employers. Now more so than ever, organizations need to consider investing in workers to improve their performance and level of satisfaction. These investments can...

Gezond thuiswerken (working from home healthily)

Anne van der Put
The research project Gezond thuiswerken (working from home healthily) of Utrecht University aimed to study the health and well-being of Dutch employees that worked from home during the covid-19 pandemic. To stop the spread of infections, the Dutch government advised employees to work from home as much as possible during the data collection period (March-July 2021). As a result, many employees worked from home for the majority of their working hours, while before March 2020...

Monitoring of Antibiotic Resistance in Veterinary Pathogens by re-use of data? Validation of existing databases

Jobke van Hout, Thijs Derkman, Maaike Gonggrijp, Annet Heuvelink, Jeanine Wiegel, Els Broens, Marloes Van Dijk & Nonke Hopman
The emergence and spread of antimicrobial resistance (AMR) is considered a serious public health threat with use of antimicrobials in animals considered as one of the potential risk factors. In the Netherlands, veterinary use of antimicrobials (AMU) has been decreased substantially in the last decade and gradually the focus shifts to ‘prudent use’: reduction and refinement of AMU. To achieve 'prudent use' in practice, among others evidence-based treatment guidelines are required and therefore knowledge on...

Microstructural data used in “Drill core from seismically active sandstone gas reservoir yields clues to internal deformation mechanisms”

Berend Antonie Verberne, Suzanne J.T. Hangx, Ronald P.J. Pijnenburg, Maartje F. Hamers, Martyn R. Drury & Christopher J. Spiers
Europe’s largest gas field, the Groningen field (the Netherlands), is widely known for induced subsidence and seismicity caused by gas pressure depletion and associated compaction of the sandstone reservoir. Whether compaction is elastic or partly inelastic, as implied by recent experiments, is a key factor in forecasting system behavior and seismic hazard. We sought evidence for inelastic deformation through comparative microstructural analysis of unique drill core recovered from the seismogenic center of the field in...

Original microstructural data of altered rocks and reconstructions using generative adversarial networks (GANs)

Hamed Amiri
We image two altered rock samples consisting of a meta-igneous and a serpentinite showing an isolated porous and fracture network, respectively. The rock samples are collected during previous visits to Swartberget, Norway in 2009 and Tønsberg, Norway in 2012. The objective is to employ a deep-learning-based model called generative adversarial network (GAN) to reconstruct statistically-equivalent microstructures. To evaluate the reconstruction accuracy, different polytope functions are calculated and compared in both original and reconstructed images. Compared...

µCT data for \"A new method for determining fluid flux at high pressures applied to the dehydration of serpentinites\"

Lisa Eberhard
Dehydration of serpentine within a subduction zone setting causes the formation of pore space. The porosity and connectivity of the pores is important for fluid flux through these rocks. The pore space preserved within two recovered high-pressure and high-temperature multi-anvil samples was measured using µCT-scans at the BL20XU experimental hutch 2 of the SPring-8 synchrotron facility. The 3D images were obtained using X-rays with energy of 30 keV and by rotating the sample through 180°...

Corpus of Dutch tweets containing kinship terms

Michelle Suijkerbuijk
A corpus of 2400 tweets, collected for research into marking of Dutch kinship terms. We searched Twitter for 24 Dutch kinship terms and selected the first 100 positive hits. A hit was considered positive when it included the kinship term, and the term was pre--modified by 1) a possessive pronoun 2) a definite article or 3) a zero-marker. It was excluded when the kinship term was used with a different meaning and when there was...

Microstructural data and microscopic stress measurements of natural mineral-hydration reactions

Oliver Plümper
We investigated the microstructures of periclase-to-brucite hydration domains within marble from the Adamello contact aureole (Italy). The microstructure preserve high differential stresses within the calcite surrounding the hydration domains of up to 1.5 GPa. Samples were investigated using optical, scanning and transmission electron microscopy as well as high-angular resolution electron backscatter diffraction (HREBSD). Stress measurements obtained via HREBSD are compared to analytical solutions. The data is organised in 10 folders termed (Supplementary) Figure X, where...

Geomechanical, seismological, and geodetic data pertaining to the Groningen gas field: a data package used in the \"Mmax II Workshop\", on constraining the maximum earthquake magnitude in the Groningen field

Stephen Oates, Anke Jannie Landman, Onno van der Wal, Hermann Baehr & Harry Piening
The operator of the Groningen gas field, the Nederlandse Aardolie Maatschappij (NAM) has been developing and refining a seismic hazard and risk model as part of the response to induced earthquakes seen in the Groningen gas field since the early ‘90s. As part of these efforts, a workshop was conducted to address the question of the maximum earthquake magnitude, Mmax, that should be considered in the seismic hazard and risk modelling. An international panel of...

In-situ Distributed Strain Sensing (DSS) data from the Zeerijp-3a well in the Groningen gas field, the Netherlands. Period 2015-2021

Pepijn R. Kole & Rob M.H.E. van Eijs
The Groningen gas field is the largest gas field in Europe. Gas production in this field has led to seismicity and surface subsidence, both believed to be caused by compaction of the underlying reservoir sandstone. In 2015, the field operator (Nederlandse Aardolie Maatschappij - NAM) installed a fibre optics cable in the Zeerijp-3a well, at a true vertical depth of about 2900 to 3200 m, i.e. in and around the gas reservoir. The Zeerijp-3a well...

Data supplement to the GLOBGM v1.0: a parallel implementation of a 30 arcsec PCR-GLOBWB-MODFLOW global-scale groundwater model

Jarno Verkaik & Edwin H. Sutanudjaja
The GLOBGM is the PCR-GLOBWB MODFLOW global-scale Groundwater Model at 30 arcsecond spatial resolution (~ 1km at the equator) that makes usage of high performance computing. The current version 1.0 uses off-line data from PCR-GLOBWB. For simulating steady-state or transient groundwater flow, a new distributed ry parallel prototype of MODFLOW 6 is being used, that has been developed together with the United States Geological Survey (https://github.com/verkaik/modflow6-parallel.git, https://doi.org/10.5281/zenodo.5778658).
