title: The Belgian hybrid quasi-geoid: hBG18

description: hBG2018 is the hybrid quasi-geoid model for Belgium, including both the Belgian mainland and the Exclusive Economic Zone. The hBG18 quasi-geoid heights are referred to the ETRS89/GRS80 ellipsoid. It is computed using radar altimetry data, terrestrial gravity anomalies, airborne gravity disturbances, and shipboard gravity anomalies. The quasi-geoid computation is based on the remove-compute-restore procedure. The long-wavelength signal content in the data is reduced by removing the contribution of the GOCO05S global gravity field model complete to degree 280. At the very short wavelengths, residual terrain modelling (RTM) is applied to the shipboard, terrestrial and airborne gravity datasets using EuroDEM as input data. The residual disturbing potential is parameterized over the target area using Spherical Radial Basis Functions (SRBF). The SRBF coefficients and bias parameters for the sets of gravity anomalies and disturbances are estimated using weighted least-squares with regularization, assuming white noise. To support the exploitation of the hBG2018 gravimetric quasi-geoid for the conversion of GNSS derived heights to the TAW/DNG height system, several post-processing steps were applied. First, as the TAW/DNG height system is a mean-tide height system (i.e., mean-tide crust = zero crust over mean-tide geoid) the quasi-geoid was transformed from the zero-tide to the mean tide system. Thereafter, a corrector surface (also called 'innovation function') has been estimated from the differences between the geometric quasi-geoid at 3707 GNSS/leveling points and the gravimetric quasi-geoid. This surface also accounts for the difference between the fictitious datum point of the gravimetric hBG18 and the datum point of the TAW/DNG. Finally, the transformation from the tide-free permanent tide system adopted in the GNSS community and the mean-tide system adopted in TAW/DNG, has been applied. hBG18 replaces hBG03 as the official Belgian model since August 1, 2018. The geoid model is provided in ISG format 2.0 (ISG Format Specifications), while the file in its original data format is available at the model ISG webpage.
description: The International Service for the Geoid (ISG) was founded in 1992 (as International Geoid Service - IGeS) and it is now an official service of the International Association of Geodesy (IAG), under the umbrella of the International Gravity Field Service (IGFS). The main activities of ISG consist in collecting, analysing and redistributing local and regional geoid models, as well as organizing international schools on the geoid determination (Reguzzoni et al., 2021).

title: Balanced cross sections along the Giudicarie Belt (Southern Alps, Northern Italy) in 3-D Move

description: Neogene indentation of the Adriatic plate into Europe led to major modifications of the Alpine orogenic structures and style of deformation in the Eastern Alps. Especially, the offset of the Periadriatic Fault by the Northern Giudicarie Fault marks the initiation of strike-slip faulting and lateral extrusion of the Eastern Alps. Questions remain on the exact role of this fault zone in changes of the Alpine orogen at depth. This necessitates quantitative analysis of the shortening, kinematics and depth of decoupling underneath the Northern Giudicarie Fault and associated fold-and thrust belt in the Southern Alps. Tectonic balancing of a network of seven cross sections through the Giudicarie Belt parallel to the local shortening direction reveals that it comprises two kinematic domains with different amounts and partly overlapping ages of shortening. This data publication provides the cross sections that were not shown within Verwater et al. (2021, submitted to Solid Earth) (see figure A1.1 for section traces) but show lateral variations in shortening in present-day cross-sections across the study area (section A1.1). Cross sections 1, 5 and 6, which are discussed within the manuscript, will be described in more detail within section A1.2 (cross section 1), A1.3 (cross section 5) and A1.4 (cross section 6). In addition, the approach used for forward modelling in Move will be shown within section A2, as well as alternative kinematic scenarios that were tested for Cross sections 6. Section B describes the methods and datasets used for obtaining the location and depth of seismicity plotted along cross sections 1, 5 and 6 in Verwater et al. (submitted).

title: Global Distribution of Frost Cracking Intensity during Late Cenozoic Time-slices

description: This dataset includes the first order (global) distribution of frost cracking intensities (FCI) [°C m], for selected paleoclimate time-slices during Late Cenozoic, as presented in the paper by Sharma et al. (2022). The paleoclimate time-slices correspond to Pre-Industrial (~1850 CE, PI), Mid-Holocene (~6 ka, MH), Last Glacial Maximum (~21 ka, LGM) and Pliocene (~3 Ma, PLIO). The FCI (by segregation ice growth) is predicted using the approach of Andersen et al. (2015), as a function of subsurface thermal gradient and volume of (and distance to) liquid water. The paleo-temperature reconstructions are obtained from ECHAM5 general circulation model (GCM) at T159 spatial resolution (80 km * 80 km) by Mutz et al. (2018). The spatial resolution of FCI dataset is same as ECHAM5 GCM simulations (i.e. 80 km * 80 km). The dataset comprises the following: - Scripts (Python) for modeling FCI for approach described in Sharma et al. (2022). - Global FCI distribution as netCDF and ascii formats. The data is available in both netCDF and ascii formats. However, the model code (attached Python scripts) currently supports only netCDF format. The model scripts can be freely utilized for regional and local studies which require finer resolution dataset. Please refer to the associated data description file for a detailed description of the dataset.
description: The model is based on the approach of Andersen et al. (2015) to estimate FCI as a function of subsurface thermal gradients up to the depth of 20 m. For segregation ice growth, it additionally considers the influence of volume of water available in the proximity of an ice lens. The boundary condition includes the presence of positive temperatures (T &gt; 0 °C) at either boundary (at surface or 20 m depth). The frost cracking is supported if the bedrock temperature is in the frost cracking window (–8 °C and –3 °C). The integrated FCI each grid cell, across Earth’s terrestrial surface was calculated by depth integration of the FCI averaged over a period of 1 year. The unit of FCI data is °C m.

title: Whole-rock geochemistry of rock units from the Pfitscher Joch area, Western Tauern Window

description: In the Western Tauern Window, Zillertal Alps (Austria/Italy), metasediments of a Mesozoic intra-montane basin ("Pfitsch-Mörchner basin"; Veselá and Lammerer, 2008) are exposed. The (me-ta)sediments were deposited on a Variscan basement, which comprises different types of meta-granitoids and their (Pre)-Variscan metamorphic country rocks. The chemical composition (major and trace elements) of these rocks is presented for 205 samples. In the metasediments (103 samples), we distinguish the following units (from base to top): metaconglomerate (14 samples) – mica schist (19) – carbonate-mica schist (9) – tourmaline gneiss (35) – lazulite quartzite (25) – marble (1). In the basement to the NW of the basin, we distinguish two different types of orthogneiss (both Zentralgneis of the Tux unit, in the local nomenclature two varieties Augenflasergneis and Schrammacher gneiss; 32 samples) and the roof pendant of these gneisses with serpentinite (10 samples), amphibolite, and paragneiss (no analyses presented). In the SE of the basin we distinguish orthogneiss from the Zillertal branch of the Zentralgneis (7 samples), biotite-chlorite-plagioclase gneiss (9 samples), amphibolite, and (Pre-)Variscan graphitic micaschist with the local name Furtschagl schist (no analyses presented), and at the base of the basin sediments a schistose pyrite quartzite (31) with lenses of magnetite-chloritoide-staurolite-chlorite rich rocks (13 samples MCSC-lenses, interpreted as paleosol, Barrientos and Selverstone, 1987). From a subset of these samples (23 samples), rare earth elements were determined, and from another subset of 25 samples 11B/10B boron isotope ratios and whole rock B-contents. This extends a previously published data set of B isotope ratios in tourmaline from the metasedimen-tary unit (Berryman et al. 2017). For a test of stratigraphic correlation, typical rocks from the meta-conglomerate, the carbonate-mica schist, lazulite quartzite, and marble (one sample each) were analyzed for 87Sr/86Sr isotope ratios.

title: U-Pb data from cherts (Onverwacht Group) and strain data from conglomerates (Moodies Group) from the southern margin of the Archean Barberton Greenstone Belt, Eswatini

description: The southern margin of the Barberton Greenstone Belt in Eswatini limits one of the world’s oldest well-preserved sedimentary and volcanic sequences, 3.57 to 3.2 Ga old. In a segment along that margin, older mafic and ultramafic volcanic rocks were thrust over the youngest strata (quartz-rich sandstones and conglomerates) before being folded and imbricated in thrust slices. Samples described in this publication comprise tabular data of (1) sample locations and crystallization ages of zircons which were extracted from thin tuffaceous units in the thrust sheet, (2) analytical data from laser ablation – inductively coupled plasma – mass spectrometry (LA-ICP-MS), supporting these ages, and (3) quantitative measurements of ductily deformed conglomerate clasts. Field data were collected 2012-2019; U-Pb analyses performed in 2020. The data presented here are the basis for geological maps and cross sections, and are visualized as concordia diagrams form part of in the related publication (Heubeck et al.. 2023).

title: 3D structural geological model of the Central South Wales Syncline, Great Britain

description: South Wales is characterised by a rich variety of geologic formations and rocks of different ages and periods, and a large asymmetric syncline, as perhaps its most significant structural geological feature, extending from east to west over a length of approximately 96 km and 30 km from north to south, respectively. This oval-shaped syncline is part of the Variscan orogenic thrust and fold belt in Central Europe and covers some 2,700 km2, with coal-bearing rocks from the Upper Carboniferous (Westphalian Stage) deposited in the central syncline and older rocks outcropping in a peripheral belt around it. The coal-bearing sequence begins with Namurian grits and shales, overlain by the more productive Lower, Middle and Upper Coal Measures. A 3D structural geological model has been implemented for the central part of the South Wales Syncline and its bedrock geology. The oldest rocks in the model domain date back to the Pridoli Series from the uppermost Silurian, the youngest to the Westphalian Stage of the Upper Carboniferous. For model implementation, mainly open access data from the British Geological Survey (BGS) has been used. The final 3D structural geological model covers the entire Central South Wales Syncline and is 32.8 km wide and 36.6 km long. In total, the 3D model includes 21 fault zones and the elevation depth of ten surfaces: (1) Top Upper Coal Measures Formation; (2) Top Middle Coal Measures Formation; (3) Top Lower Coal Measures Formation; (4) Top Millstone Grit Group; (5) Top Dinantian Rocks; (6) Top Upper Devonian Rocks; (7) Top Lower Devonian Rocks (sandstone dominated); (8) Top Lower Devonian Rocks (mudstone dominated); (9) Top Pridoli Rocks; (10) Top Ludlow Rocks (in parts).

title: 3D DAS-VSP data from the Groß Schönebeck site, Germany, February 2017

description: An extensive vertical seismic profiling (VSP) survey using wireline distributed acoustic sensing (DAS) technology was carried out between the 15th and 18th of February 2017 at the geothermal in-situ laboratory Groß Schönebeck, Germany. Borehole measurements were recorded in two 4.3 km deep wells E GrSk 3/90 and Gt GrSk 4/05. Two hybrid fibre optics cables were freely lowered inside the wells to form dense receiver arrays. As a seismic source, four heavy vibroseis trucks were used. The survey consisted of 61 source positions distributed in a spiral pattern around the target area. This data publication consists of raw uncorrelated seismic data acquired for 3D seismic imaging purposes. Supplementary information such as well trajectories, source point coordinates, and the pilot sweep data is also provided. Data related to zero-offset measurements can be found in Henninges et al. (2021, https://doi.org/10.5880/GFZ.4.8.2021.001). Further details on the survey design and data acquisition parameters can be found in Henninges et al. (2021, https://doi.org/10.5194/se-12-521-2021); Martuganova et al. (2021, 2022). Information on high-resolution 3D reflection seismic acquisition campaign carried out at Groß Schönebeck in February–March 2017 can be found in Krawczyk et al. (2019); Bauer et al. (2020); Norden et al. (2022). The 3D DAS VSP processing workflow, 3D DAS imaging results, and comparison with 3D surface seismics are presented in Martuganova et al. (2022).

title: Input and resulting structural and parameterized subsurface data for a geological model of the geothermal research platform Groß Schönebeck (North German Basin)

description: The dataset presented in this compilation provides the input data used for the geological interpretation and for the model parameterization (Norden et al., 2022) of a 3D seismic survey in the area of the geothermal research platform Groß Schönebeck (carried out in 2017; Krawczyk et al., 2019), focussing on the deep Permo-Carboniferous geothermal targets. The geothermal research platform Groß Schönebeck is located about 50 km north of Berlin, on the southern edge of the Northeast German Basin, and is equipped with two deep wells, the E GrSk 3/90 and Gt GrSk 4/05 boreholes. In this data compilation we provide general data on the location of the boreholes and data on the applied methods and the interpretation of petrophysical properties (density, porosity, permeability, thermal properties) obtained by core analysis and well-log interpretation. Because cores were available for the E GrSk 3/90 borehole only, most of the data is referring to the borehole that was drilled more or less vertically. The other borehole (Gt GrSk 4/05) is a deviated well, drilled as a geothermal production well. Further on, we provide the main interpreted structural reflector horizons of the geological model from surface to the assumed top of sedimentary Carboniferous (for discussion of the uncertainty of this boundary please consider the comments in Norden et al., 2022) and the horizons and 3D grid properties of a parameterized simulation grid for the deep geothermal target (sedimentary Rotliegend and Permo-Carboniferous volcanic rocks).

title: Time series of meteorological stations on an elevational gradient in National Park La Campana, Chile

description: The DFG Priority Program 1803 "EarthShape - Earth Surface Shaping by Biota” (www.earthshape.net) installed three meteorological stations at an elevational gradient in the National Park La Campana, Chile, in the sector Ocoa, within one catchment, that is one of the four EarthShape core research sites. They are located at a valley position, at the slope and the crest of the catchment. For reference, the valley station is neighbouring a weather station (Campbell Scientific) that the EarthShape project has installed earlier, in 2016 (Übernickel et al., 2020). The other two weather stations are installed on higher elevations. The weather stations are intended to provide baseline meteorological data along the elevational gradient within the La Campana catchment. Each station is configured to include sensors that record air temperature, relative humidity, barometric pressure as well as total solar radiation at 2 m height; precipitation at 1 m height. The data recording started in March 2019. This publication provides raw data as downloaded from the three stations, appended to one single *.xlsx file per station. The data is measured in 30 minutes intervals. The full description of the data and methods is provided in the data description file.
description: The DFG Priority Program 1803 "EarthShape - Earth Surface Shaping by Biota" (2016-2022; https://www.earthshape.net/) explored between scientific disciplines and includes geoscientists and biologists to study from different viewpoints the complex question how microorganisms, animals, and plants influence the shape and development of the Earth’s surface over time scales from the present-day to the young geologic past. All study sites are located in the north-to-south trending Coastal Cordillera mountains of Chile, South America. These sites span from the Atacama Desert in the north to the Araucaria forests approximately 1300 km to the south. The site selection contains a large ecological and climate gradient ranging from very dry to humid climate conditions.
