title: Operational Dataset about drilling in the Moodies Group of the Barberton Greenstone Belt (BASE – Barberton Archean Surface Environments)

description: All datasets provided in the operational dataset (Heubeck et al., 2024) of the ICDP project BASE (ICDP 5069) consist of metadata, data and/or images. Here, a summary of explanations of the tables, data and images exported from the database of the project (mDIS BASE) are given and are complemented by additional information on data from measurements done in the laboratory prior to the sampling party. Finally, the sampling data from the first two sampling parties are added. Some basic definitions of identifiers used in ICDP, depths corrections and measurements are also introduced. 
 
The BASE (Barberton Archean Surface Environments) scientific drilling project focused on recovering unweathered continuous core through strata of the Paleoarchean Moodies Group (ca. 3.2 Ga), central Barberton Greenstone Belt (BGB), South Africa. They comprise some of the oldest well-preserved sedimentary strata on Earth, deposited within only a few million years in alluvial, fluvial, coastal-deltaic, tidal, and prodeltaic settings; they represent a very-high-resolution record of Paleoarchean surface conditions and processes. Moodies Group strata consist of polymict conglomerates, widespread quartzose, lithic and arkosic sandstones, siltstones, shales, and rare BIFs and jaspilites, interbedded with tuffs and several thin lavas. This report describes operations from preparations to the sampling workshop and complements the related scientific report. 
 
Eight inclined boreholes between 280 and 495 m length, drilled during November 2021 through July 2022, obtained a total of 2903 m of curated core of variable quality through steeply to subvertically dipping, in part overturned stratigraphic sections. All drilling objectives were reached. Boreholes encountered a variety of conglomerates, diverse and abundant, mostly tuffaceous sandstones, rhythmically laminated shale-siltstone and banded-iron formations, and several horizons of early-diagenetic sulfate concretions. Oxidative weathering reached far deeper than expected; fracturing was more intense, and BIFs and jaspilites were thicker than anticipated. Two km-long mine adits and a water tunnel, traversing four thick stratigraphic sections within the upper Moodies Group in the central BGB, were also sampled. All boreholes were logged by geophysical instruments. Core was processed (oriented, slabbed, photographed, described, and archived) in a large, publicly accessible hall in downtown Barberton. An exhibition provided background explanations for visitors and related the drilling objectives to the recently established Barberton-Makhonjwa Mountains World Heritage Site. A substantial education, outreach and publicity program addressed the information needs of the local population and of local and regional stakeholders.

title: Database of in-situ Raman spectra from Na2H2ATP solutions at 80,100 and 120 °C and up to 1666 MPa for determination of the rate constant of the ATP hydrolysis

description: In biochemical systems, enzymes catalyze the endergonic phosphorylation of adenosine diphos-phate (ADP) to adenosine triphosphate (ATP) by different pathways, e.g., oxidative phosphoryla-tion catalyzed by membrane bound ATP synthase or substrate-level phosphorylation. The stored energy is released by the enzymatically controlled exergonic hydrolysis of ATP to power other vital endergonic reactions; therefore, ATP is widely known as the universal energy currency. Rapid abiotic ATP hydrolysis kinetics thus means higher maintenance energy costs for cells, and it has been suggested that this is an important factor in setting the limits to the functioning of living organisms (Bains et al. 2015). In order to evaluate the running conditions of the in-situ procedure by Moeller et al. (2022) using Raman spectroscopy opened up an efficient way of obtaining further insights to the effects of P-T- ionic composition on the kinetics of ATP-ADP hy-drolysis. Raman spectroscopy can be combined with a hydrothermal diamond anvil cell, which provides an isochoric system for measurements up to pressures of 2000 MPa. Another system for in-situ Raman spectroscopy at elevated pressures and temperatures is based on an autoclave fitted with optical high-pressure windows, as shown by Louvel et al. (2015) and works up to 200 MPa. In this system, pressure and temperature can be controlled independently, so that isobaric temperature series are possible. 
 
This data publication compromises all Raman spectra measured in-situ of Na2H2ATP solutions at 80, 100 and 120 °C and up to 1666 MPa to determine the rate constants of the hydrolysis of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) at 48 different P-T conditions. Furthermore, an assignment of peaks in the fitted range, the initial fit parameters and the fit-results are provided. Besides the kinetic data, the pH of the ATP solutions was calculated at experimental temperature and pressure conditions.

title: Soil moisture response, stable water isotope profiles, and trinary images of vertical subsurface flow paths across the evolution of siliceous and calcareous soil in proglacial areas

description: The data set was collected to identify hydrological processes and their evolution over it time. It consists of several individual files in tabstop delimeted text format. The data set contains the data obtained from deuterium and brilliant blue tracer experiments at two chronosequence studies in the glacier forefield of the Stone Glacier and the Griessfirn in the central Alps, Switzerland. Each chronosequence consisted of four moraines of different ages (from 30 to 13500 years). At each forefield sprinkling experiments with deuterium and dye tracer experiments with blue dye (Brilliant Blue) were conducted on three plots per moraine. The moraines at the forefield of the Stone Glacier developed from siliceous parent material and at the forefield of the Griessfirn from calcareous parent material. Data from the siliceous forefield are marked with (S) and data from the calcareous forefield are marked with (C). The data set consist of soil moisture time series and soil water isotope profiles of the sprinkling experiments with deuterium, as well as trinary images of stained vertical subsurface flow paths from the dye tracer experiment. The individual plots per moraine are distinguished via their position relative to one another on the moraine (left, middle, and right, looking upslope). 
The plots used for the sprinkling experiments were located in close vicinity to the plots used for the dye tracer experiments. For the sprinkling experiments with deuterium each plot (4m x 6m) per age class was equipped with 6 soil moisture sensors. Three of these sensors were installed as a sensor profile at one side of the plot about one meter downslope from the upper plot boundary. The sensors were installed at 10, 30, and 50 cm soil depth. On the other side of the plot, two sensors were placed in 10 cm depth, one opposite to the sensor profile and the second sensor one meter upslope from the lower plot boundary. The sixth sensor was placed at 10 cm depth in the center of the plot. The plots were irrigated on three consecutive days with three different irrigation intensities and deuterium concentrations. Per forefield, the soil moisture data are listed in one file per age class. The file contains for each plot, the time stamp and the soil moisture values of the 6 sensors.

title: CH-ME-3-MAG - CHAMP 1 Hz Combined Magnetic Field Time Series (Level 3)

description: This is a Level 3 data daily file product from various scientific and utility sensors on board of the `LEO' satellite 'CHAMP' with magnetic field data given by a time resolution of 1 Hz. Thise Level 3 data type is build to hold and merge finally corrected data, focusing on mature data calibration and corrections -- as well as internal consistency. This Level 3 data product is intended to supersede the various Level 2 versions with calibrated magnetic field readings from the CHAMP mission distributed hitherto and should be fitted for scientific use, assembling time series of scalar magnetic field values (but not directly readings from the scalar Overhauser sensor), vector magnetic field data from the boom-mounted Fluxgate 'FGM' sensors and attitude data from the ('ASC') boom-mounted Star Cameras. The vector data are given both in the satellite-bound sensor ('FGM') system and the Earth Centered Earth Fixed local 'NEC' (North-East-Center) system. The attitude time series, processed and cleaned, are represented by quaternions describing the satellite attitude related to the celestial system. The readings of the scalar OVM (Overhauser) absolute magnetometer at the top of the boom are not supplied directly, but were used during calibration of the vector magnetometer readings. The files with daily time coverage are in the (binary and self-describing) 'CDF' file format and accompanied, beside the generic 'CDF'-format timestamp, by the satellite's geocentric positions and utility information like quality flags.

title: Laboratory Investigation of Fracture Behavior and Roughness Evolution in Simulated Hydraulic Shear Stimulation for Enhanced Geothermal Systems (EGS)

description: Enhanced Geothermal Systems (EGS) utilize artificially induced fracture networks to enable fluid circulation and heat extraction from high-temperature, low-permeability geological formations. Unlike conventional hydraulic fracturing in the hydrocarbon industry—which commonly employs proppants to keep fractures open—EGS stimulation primarily relies on hydraulic shear stimulation. This technique leverages the self-propping behavior of pre-existing fractures, eliminating the need for proppants. To replicate hydraulic shear stimulation in a controlled laboratory setting, we conducted shear-flow experiments on various fracture types, including shear fractures, tensile fractures, and saw-cut fractures. Most previous studies have focused on tensile and saw-cut fractures, typically treating them as idealized representations of smooth or rough fracture surfaces. However, shear fractures—due to their naturally formed characteristics—offer a more realistic simulation of in-situ conditions and better represent pre-existing fractures in the field. To evaluate fracture surface roughness, we employed a 3D laser scanner. The digitized surface data, captured both before and after the shear-flow tests, were recorded in .CSV files for subsequent analysis.

title: In-situ groundwater storage variations in the Central Highlands of Vietnam

description: This dataset contains large-scale groundwater storage anomalies for the Sesan and Srepok catchments in the Central Highlands of Vietnam. The anomalies were derived from in-situ groundwater well water level time series and hydrogeological information. A detailed description of the datasets and methods can be found in Sayyadi et al 2025. 
 
The dataset is comprised of three files: insitu_groundater_storage_anomalies.csv, GW_wells.csv and a shape file with the Thiessen polygones indicating the extent of the area for which the storage calculations were performed. 
 
insitu_groundater_storage_anomalies.csv contains the groundwater storage variations, with the following columns: 
 
1. gws_mm (Groundwater Storage in millimeters): The gws_mm data represent groundwater storage anomalies derived from in-situ well measurements. Groundwater levels were recorded monthly from a network of observation wells across the study area. Specific yield values were used to convert the groundwater level variations into storage anomalies, measured in millimeters of water equivalent. 
 
2. seasonal_adjusted: The seasonal_adjusted data were obtained by removing the seasonal component from the raw groundwater storage time series (gws_mm). This was done by calculating the mean monthly anomalies and subtracting them from the original data to isolate non-seasonal variations. 
 
3. trend: The trend data represent the linear trend component of the groundwater storage anomalies. The trend was calculated using a linear regression model applied to the seasonal-adjusted data, highlighting long-term groundwater storage changes over the study period. 
 
4. detrended: The detrended data were created by removing both the seasonal and long-term trend components from the gws_mm data. This dataset captures short-term fluctuations and anomalies, free from the regular seasonal and trend influences. 
 GW_wells.csv contains a list of the griundwater wells used in the study, with information about their location and lithology, as well as the range of associated specific yields (sy). 
 
Thiessen_polygones_GW_wells_2S.shp is a georeferenced shape sile containing the Thiessen polygones for the wells in GW_wells.csv.

title: Seismic properties and mineralogy of core samples from the COSC-1 borehole, Sweden

description: Core samples have been taken for complementary laboratory seismic measurements and mineralogical analyses on whole rock core from the COSC-1 borehole, Sweden (UTM 63.3124, 13.5259). These samples were used to provide and characterize the seismic properties (i.e., seismic velocities and anisotropy) of the drilled rocks from the highly metamorphosed and deformed Seve Nappe Complex, an orogenic thrust zone in the Scandinavian Caledonides, in central Sweden. 
 
The laboratory seismic and mineralogical analysis in general comprises three distinct measurements (i.e., data sets), which will be described in detail in the following subsections: (1) P- and S-wave laboratory seismic measurements on three perpendicular core plugs, under different confining (hydrostatic) pressure conditions (10 + 6 samples), (2) Bulk mineralogy of core plugs using X-ray powder diffraction (XRD) and mineral chemical composition measurements using an electron probe micro-analyzer (EPMA, here microprobe), on 10 thin sections and (3) Microstructural investigations based on electron-backscatter diffraction analyses on 5 thin sections. 
 
The laboratory seismic measurements were initially conducted on 6 samples by Wenning et al. (2016) and extended by another 10 samples by Kästner et al. (2020). Despite these authors were using the same sensor setup, the provided data files may differ due to individual acquisition parameters. Where different acquisition, processing, or calibration parameters are used this is indicated in the text using the abbreviations FK and QW referring to each examiner and their related sample measurements. International Geo Sample Numbers (IGSN) are provided for each core sample in the complete sample data table.

title: Geophysical Imaging of Deep EarthShape (GIDES): 3-components passive seismic data of La Campana, Chile

description: This data publication provides access to three-component (3C) passive seismic data collected in the National Park La Campana, Chile. The data acquisition was conducted as part of the EarthShape project, specifically the Geophysical Imaging of the Deep Earth (GIDES) initiative. The seismic array was strategically positioned to intersect an existing borehole location. This borehole boasts a wealth of data, including core samples and geophysical logging information. The passive seismic data plays a crucial role in imaging the structure of the deep weathering zone beneath the surface. The dataset includes the raw data captured by the CUBE data logger. This raw data can be converted into the widely used miniSEED format using the freely available GIPP (Geophysical Instruments Pool Potsdam) tools. This conversion facilitates seamless integration with other seismic analysis software, promoting broader utilization of the data by the scientific community.
description: The Geophysical Instrument Pool Potsdam (GIPP) provides field instruments for (temporary) seismological studies (both controlled source and earthquake seismology) and for magnetotelluric (electromagnetic) experiments. The GIPP is operated by the GFZ German Research Centre for Geosciences. The instrument facility is open for academic use. Instrument applications are evaluated and ranked by an external steering board. See Haberland and Ritter (2016) and https://www.gfz.de/gipp for more information.

title: CGS: A Triplet Dataset for GNSS-R Vegetation Monitoring

description: Vegetation water content (VWC) is a crucial parameter for understanding vegetation dynamics and the hydrological cycle on Earth. Spaceborne global navigation satellite system reflectometry (GNSS-R) has demonstrated promising potential in vegetation monitoring. To address the lack of large-scale datasets and foster algorithmic innovation, we introduce a triplet dataset, termed as CGS dataset, which consists of measurements from the cyclone GNSS (CYGNSS), global land data assimilation system (GLDAS), and soil moisture active passive (GLDAS). With a timespan of over three years, observations from these missions are aggregated, filtered, and collocated with standardized quality control and spatiotemporal alignment. The CGS dataset includes variables that describe reflected signal characteristics, surface attributes, and hydrological parameters to support reproducibility and enable further analyses.

title: Future Flood Losses to Company Assets in Europe

description: The dataset presents quantification of fluvial flood risk of company assets by integrating flood hazard scenarios with flexible state-of-the-art Bayesian Network-based flood loss model and object-specific exposure data. The dataset consists of spatially explicit loss in terms of Expected Annual Damage (EAD) of companies (commercial and industrial sectors) for each NUTS3 region corresponding to a baseline and potential future scenarios shaped by climate change, exposure dynamics, and their combined effects. Additionally, the dataset includes simulation results under an intervention scenario "measures for all" where each company has atleast implemented one of the possible precautionary measures against flooding. In addition to the NUTS3-level EAD values, the dataset also includes loss estimates for each tile corresponding to the baseline (1995) scenario. More information on input variables, usage and calculation of EAD can be found in Devadas et al. (2025) [DOI will be updated after publication].
description: The folder contains the simulation results for all possible combinations of future years, precautionary measures, quantile and sectors. The filename for each unique combination is coded as “EAD_[precautionary measure]_[year]_[climate or exposure condition with quantile]_m[quantile of model]_[sector].csv” for Expected Annual Damages (EAD) and “LV_rp[return_period]_SQ_1995_baseline_m[quantile of model]_[sector].csv” for baseline loss values at the grid-level.
