title: Superconducting Gravimeter Data from Medicina - Level 1

description: The International Geodynamics and Earth Tide Service (IGETS) was established in 2015 by the International Association of Geodesy (IAG). IGETS continues the activities of the Global Geodynamics Project (GGP, 1997-2015) to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network.
      The gravimetric station Medicina/Italy operated by the Federal Agency for Cartography and Geodesy (BKG), Germany, and the Department of Physics and Astronomy (DIFA) at the University of Bologna, Italy, was established in 1996. Continuous temporal gravity and atmospheric pressure time series from the SG is made available to the IGETS data base hosted by ISDC (Information System and Data Center) at GFZ.
      The gravimetric station is located at the premises of the Medicina Radio Observatory (Northern Cross) of Istituto Nazionale di Astrofisica (INAF), 30 km south-east from Bologna in the southeastern Po Plain. The plain runs parallel to the Pede–Apenninic border and represents a sediment-filled foredeep, where a huge sedimentary deposition (more than 5000 m of thickness) occurred during the Plio-Pleistocene. The uppermost stratigraphic sequences in the Plain are made of alternating sands, silts and clays variably interbedded and normally consolidated.
      Since 1996, an almost uninterrupted time series of gravity and barometric pressure variations are acquired with SG C-023. In the same year a series of repeated absolute gravity measurements with different AGs started.
      Although the gravity building is not well thermally isolated, the air-conditioning system compensates main temperature variations, keeping the room temperature stable within a range of 5 K. The hut facilitates three pillars of concrete in one room, one used for the SG and two for absolute gravimeters. All pillars show a slight seasonal tilting due to soil consolidation. This effect is mostly compensated by tilt compensation system of the SG.
      Since June 1995 and November 2004, data from two ground water wells, one in a distance of 500 m, the other nearby, are recorded, supporting the monitoring of local water storage changes.

title: Superconducting Gravimeter Data from Membach - Level 1

description: The International Geodynamics and Earth Tide Service (IGETS) was established in 2015 by the International Association of Geodesy (IAG). IGETS continues the activities of the Global Geodynamics Project (GGP, 1997-2015) to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network. The Membach station is located near the river Vesdre. It consists of a 130 m long gallery excavated in the side of the valley that rises to the Hautes Fagnes plateau. At the end of the gallery, there are two rooms, located at ~45 m below the ground surface. Room 1 is dedicated to absolute gravity and seismic measurements; room 2 houses the superconducting gravimeter. The structure of the gallery and the rooms is in reinforced concrete. It was built in the early 1970s to monitor the seismic activity in the vicinity of the Gileppe and Eupen water reservoirs. Works were performed contemporeanously with the raising of the Gileppe dam. The gallery has been excavated in low-porosity argillaceous sandstone with quartzitic beds. As a function of rainfall and seasonal effects, gravity variations up to 40 nms-2 have been observed, and are mostly due to groundwater changes in the vadose zone above the underground laboratory (Van Camp et al., 2006). Strong rainfall induces rapid gravity decreases (Meurers et al 2007; Delobbe et al., 2019). At the surface, a beech forest. Absolute gravity measurements have been performed on average every month since 1996, using the FG5#202 gravimeter and the station is also the reference point for the Belgian gravity network. The SG GWR#C021 has been operating continuously since 1995 August so that, since 2017 September 18, it holds both records for the longest continuous time spent measuring gravity variations in the same place and for the longest superconducting levitation of an artefact (Van Camp et al., 2017). For high precision works like Earth tides analysis on long time series, data should not be used before 1998 June 12, when the original "TIDE" card in the SG electronics was replaced by the "GGP" one. Filters are different, and so are the transfer functions. Moreover, in this early period, the SG suffered from numerous technical issues, causing several changes in the amplitude and phase calibrations and making it difficult to ensure that the data are as reliable as after 1998 June.

title: Experimental insights on experimental volcanic lightning under varying atmospheric conditions

description: This data publication provides data from 39 experiments performed in 2021 to 2022 in the Gas-mixing lab at the Ludwig Maximilian University of Munich (Germany). The experiments were conducted to investigate the charging and discharging potential of decompressed soda-lime glass beads in varying enveloping gas composition and two different transporting gas species (argon and nitrogen). The experimental setup is a modified version of an apparatus first developed by Alidibirov and Dingwell (1996) and further modified by Cimarelli et al. (2014), Gaudin and Cimarelli (2019), and Stern et al. (2019) to enable the detection and quantification of discharges caused by the interaction of the discharging particles. The latest modifications enable the setup to perform experiments under gas-tight conditions allowing to test different atmospheric composition and pressure and to sample the gas within the particle collector tank. The sample material was ejected from the autoclave into the particle collector tank that is insulated from the autoclave and works as a Faraday cage. Discharges going from the jet to the nozzle were recorded by a datalogger. Additionally, the ejection of the decompressed material was recorded by a high-speed camera. The gas composition in the collector tank was changed from air to CO2 and a mixture of CO2 and CO. The particle collector tank was conditioned in two different modes: purging three times the tank with the desired gas composition or three times of purging and applying a vacuum in between. Analysis of gas samples taken from the collector tank before conducting the experiments revealed that in both cases a complete removal of the air was not achieved, but significantly reduced by the evacuation-purging method. Two gases were used to pressurize the sample within the autoclave: Nitrogen and Argon. The experimental results were compared to previous experiments (Springsklee et al., 2022a; Springsklee et al., 2022b).

title: Digitized maps of vascular plant species distributions in Denmark in the early 20th century

description: <b>Historic data are essential for quantifying changes in biodiversity and drivers thereof. A large part of such legacy data are stored undigitized in archives at e.g., natural history museums, and make up significant untapped resources for insights into past biodiversity patterns. In 1904, the Danish Botanical Society initiated the first systematic survey of species distribution within Denmark of the entire Danish flora. The largest part of the field surveys was conducted during the early decades of the 20th century. Results were published as black and white printed maps during the years 1931-1976, using dots for accurate records and hatchings for expert-assessed local abundance. We used automated georeferencing and an image classification algorithm to extract the distribution data from all published maps. Here, we present 1340 maps of historic distribution patterns of vascular plant species and subspecies in Denmark at a 10 x 10 km resolution. These maps represent the Danish flora of native and archaeophyte species known at the time, except a few of the most common native species that were not mapped. These digital maps can be used to assess historic patterns of species distributions and occupancy. By comparing with modern distribution data, species increases and decreases can be determined, contributing to large-scale synthesis of national, European or worldwide plant diversity changes in the modern era.</b><br><b>Data description</b><b>Data are described in detail in "</b><b>From paper to pixels - digitized maps of vascular plant distributions in Denmark in the early 20th century".</b><b>Data consists of 1340 shapefile maps collected in the zipfile "shpmaps_2025".</b><b>Each map consists of 4 columns:</b><b>list_name refers to the species name</b><b>category (0 for "absence", 1 for "present", 2 for expert-estimated abundance "here and there", 3 for "absent, but has been found there in the past").</b><b>idgrid that links each observation to a standard grid map, "gridshp.shp".</b><b>geometry</b>All maps are collated into one shapefile in "shpmaps_list_2025.shp"<b>Georeferenced image maps are in the folder "tiff_maps".</b><b>specieslist_info.csv includes overview of species names, shapefile names, image map names, taxonomy synonyms and comparisons to World Flora Online, Dansk Feltflora (1981).

title: Drained ring-shear test data of wet silica powder-glass beads-PVC powder mixture “CM2” used for analogue modelling in the laboratory for experimental tectonics (LET) at RomaTre University, Rome, Italy

description: This dataset provides friction data from drained ring-shear tests on a wet (water saturated) silica powder-glass beads-PVC powder mixture (40:40:20 wt.%) “CM2”, used in analogue modelling of tectonic and erosion processes as a rock analogue for the earth’s upper crust (e.g. Conrad et al., 2023, Reitano et al., 2020, 2022. 2023). According to our analysis the materials show a Mohr-Coulomb behaviour characterized by a linear failure envelope. Peak, dynamic and reactivation friction coefficients of CM2 are µP = 0.66, µD = 0.58, and µR = 0.61, respectively. Cohesion of the material ranges between 60-230 Pa. The tested bulk material CM2 consists of a mixture of 40 wt. % silica powder, 40 wt.% glass beads and 20 wt.% PVC powder which has been saturated with water (Table 1). Specification of silica powder is “Ventilated Quartz VR16” (https://www.valligranulati.it/products-granules-quartz-marble-sands-premixed/sheet-m/ventilated-quartz) by the company Valli Granulati S.r.l. (Italy). Ventilated quartz is obtained by micronisation of quartz sands with a high content of SiO2 (around 96%), and used e.g. in paints and abrasives. It should be handled with care to omit generation of dust and a half mask (filter class FFA1P2 RD) should be worn because it can harm the human respiratory tract with the potential of causing silicosis. Glass beads used here have a size (diameter) of 700-110 µm and their individual properties are described in detail Pohlenz et al. (2020). The commercial name for the PVC powder is “PVC K.57 Inovyn 257RF” by the company TPV Compound (Italy). PVC powder is mainly used for cleaning industrial structures (as abrasives) or for the production of PVC tubing, plastic sheets etc. The composition of this PVC powder is the same of the common Polyvinyl chloride. According to the regulation CE n.1272/2008 (CLP), this type of PVC powder is classified as not dangerous for the supply, also thanks to its low value of density and round shape.

title: 3D-NEA: Three-dimensional lithospheric-scale structural model of the North East Atlantic

description: The Northeast Atlantic (NEA) region has long been a subject of interest due to its complex geological history, particularly regarding the interaction between the Iceland plume and the lithospheric plates. In this data publication, we present a comprehensive three-dimensional structural and density model of the NEA crust and uppermost mantle, consolidating and integrating a wide range of previously fragmented data sets. Our model highlights the influence of the Iceland plume on the region's geological evolution, shedding light on the mechanisms that facilitated the continental breakup between Europe and Laurentia during the earliest Eocene period. The whole workflow and methods are described in Gomez Dacal et al. (2023) and its Supplementary Information.

The provided structural model consists of 11 units including: (i) sea water and ice; (ii) two layers of sedimentary cover: a shallow and a deep unit; (iii) five crystalline crust units composed of an upper and a lower continental crustal, an oceanic crust and two units of lower crustal bodies (LCB); (iv) two lithospheric mantle units: a continental and an oceanic layer. The structural model has a dimension of 2000 km x 2500 km x 300 km and is provided in regularly spaced grids of 10 km, which are identical for all model units. For the gravity modelling the model limits have been extended by 500 km horizontally in all directions including constraining information for the extended region. The extended model horizons are represented in the density model. Additionally, we provide gravity data, density voxel cube and related tomography data. Files are subdivided into five categories: 1. Structural interface 2. Density model horizon 3. Gravity data 4. Density voxel cube 5. Tomography data
