    Description: Abstract
    Description: This data publication is supplementary to the study on headwall erosion rates at Glacier d'Otemma in Switzerland, by Wetterauer et al. (2022). Debris on glacier surfaces stems from steep bedrock hillslopes that tower above the ice, so-called headwalls. Recently, rock walls in high-alpine glacial environments experience increased destabilization due to climate warming. Since supraglacial debris alters the melt behaviour of the ice underneath, increased headwall erosion and debris delivery to glacier surfaces will modify glacial mass balances. Therefore, we expect that the response of glaciers to climate change is likely linked to how headwall erosion responds to climate change. As headwall debris is deposited on the ice surface of valley glaciers it is passively transported downglacier, both supra- and englacially. Where two glaciers join, debris along their margins is merged to form medial moraines. Since medial moraine debris tends to be older downglacier, systematic downglacier-sampling of medial moraine debris and the measurement of in situ-produced cosmogenic 10Be concentrations ([10Be]) hold the potential to assess long-term (〉10^2-10^4 yrs) headwall erosion rates through time. However, to obtain the cosmogenic signals of headwall erosion, [10Be] within supraglacial debris need to be corrected for glacial transport time, as cosmogenic nuclides continue to accumulate during exposure and transport. This additional 10Be accumulation during debris transport can be accounted for by simple downglacier debris trajectory modelling. Providing our 10Be dataset together with detailed information on our 1-D modelling approach is the main objective of this data publication. The data is presented as one single xlsx-file with three different tables. A detailed description of the sample processing and the debris trajectory model are provided in the data description file of this data publication. For more information see our study Wetterauer et al. (2022).

    Description: Abstract
    Description: The main objective of the work package 2 of the REFLECT project is to characterise relevant fluid properties and their reactions for saline fluids (type C). One of the specific goals was to collect fluid samples from several saline fluids from geothermal sites across Europe, determine their properties, and thus contribute to the Fluid Atlas (WP3). Additionally, the REFLECT team will compare those field data with data from lab experiments performed at near natural conditions. Samples of type C fluids were taken from several sites in Germany, Austria, Belgium and the Netherlands. The samples were analysed for major and minor ions, dissolved gases and isotopes. One sample of thermal water was taken from the production well at Balmatt, Belgium on May 17th 2021 and sent to Hydroisotop for analysis of main cations and anions and heavy metals. It can be seen that the nitrate content is remarkably high. However, all meaurements had to be conducted from the same sample bottle, which had been acidified, presumably with HNO3 which can be expected to be the source of the high nitrate content. The dataset contains analysis results associated with the research project REFLECT. It is a comma separated file (csv) containing the following columns: Location,Country,Description,Laboratory (Lab.),Lab. No.,Sampling date,Sodium (mg/l),Potassium (mg/l),Calcium (mg/l),Magnesium (mg/l),Chloride (mg/l),Sulphate (mg/l),Nitrate (mg/l),Antimony (mg/l),Barium (mg/l),Iodide (mg/l),Lithium (mg/l),Silicon (mg/l),Strontium (mg/l),Aluminium (mg/l),Arsenic (mg/l),Lead (mg/l),Iron total (mg/l),Copper (mg/l),Manganese total (mg/l),Nickel (mg/l),Uranium (mg/l),Zinc (mg/l) Methods are described in the accompanying deliverable Fluid data of geothermal sites (type C).

    Description: Project summary: The efficiency of geothermal utilisation largely depends on the behaviour of fluids that transfer heat between the geosphere and the engineered components of a power plant. The Horizon 2020 funded project REFLECT aims to avoid problems related to fluid chemistry rather than treat them. Fluid physical and chemical properties are often poorly defined, as in situ sampling and measurements at extreme conditions have proved difficult to date. Therefore, large uncertainties in current model predictions prevail, which are being tackled in REFLECT by collecting new, high-quality data in critical areas. The data is being implemented in a European geothermal fluid atlas and in predictive models to allow recommendations on how to best operate geothermal sites sustainably and to enhance geothermal technology development.

One of the specific goals was to collect fluid samples from several saline fluids from geothermal sites across Europe, determine their properties, and thus contribute to the Fluid Atlas (WP3). Additionally, the REFLECT team will compare those field data with data from lab experiments performed at near natural conditions. Samples of type C fluids were taken from several sites in Germany, Austria, Belgium and the Netherlands. The samples were analysed for major and minor ions, dissolved gases and isotopes. In order to gain information about the increased methane content (about 65 vol-%) in the gas samples of the Groß Schönebeck production well (GrSk05/05) collected in February 2021 as compared to previous samples in 2010-2018 (10-14 vol-%), three gas samples were sampled by GFZ on 02 March 2021 at the valve at the wellhead when releasing the pressure from the wellhead. Main gas composition was measured by GFZ indicating again predominantly CH4 (63,9-64,2 Vol-%) followed by N2 (30,9 – 31,2 vol.-%) with minor amounts of H2 (3,4 vol-%) and CO2 (0,01-0,04 vol-%). Potential reasons for the increased methane content could be either microbial activity or contribution of fluid / gas from a different source within the reservoir. To determine the origin of methane, therefore, isotope analyses were performed. The samples arrived at Hydroisotop on March 13th 2021 for the analysis of higher hydrocarbons (C2-C5) and their isotopic composition (13C-CO2, 13C -CH4, 13C-CxHy and 2H-CH4). Together with the measured high amounts of higher hydrocarbons (ethane, propane etc.) they indicate a rather thermogenic source of the hydrocarbons. To better clarify the question of the source of methane, additionally, two downhole water samples from two different depths (1500 and 4000 m) were taken by GFZ on 09th and 10th of June 2021 and sent to Hydroisotop for analysis of main cations and anions, heavy metals, trace elements and isotopes (13C-CH4) in July 2021. The water sample composition resembles those of earlier measurements of samples collected in Groß Schönebeck (e.g. Regenspurg et al., 2010). However, since the well had not been in operation for a while a depth differentiation between the sample from 4000 m and the one from 1500 m is obvious. This was already visible by the black precipitate observed in the 4000 m sample, whereas the sample at 1500 m showed da reddish precipitate of presumably iron oxides. It should be noted that the nitrate content of the water samples is unusually high since reducing conditions are expected. This could have been caused by air contact of the sample and subsequent oxidation. Furthermore, a reduced silicon content shows in sample 365871 compared to sample 365870. Given the high temperature of the well, the higher silicon content is more plausible. The dataset contains analysis results associated with the research project REFLECT.

No.,Sampling date,Sodium (mg/l),Potassium (mg/l),Calcium (mg/l),Magnesium (mg/l),Chloride (mg/l),Sulphate (mg/l),Nitrate (mg/l),Antimony (mg/l),Barium (mg/l),Bromide (mg/l),Fluoride (mg/l),Iodide (mg/l),Lithium (mg/l),Silicon (mg/l),Strontium (mg/l),Aluminium (mg/l),Arsenic (mg/l),Lead (mg/l),Copper (mg/l),Manganese total (mg/l),Nickel (mg/l),Uranium (mg/l),Zinc (mg/l),Ethane (vpm),Propane (vpm),i-Butane (vpm),n-Butane (vpm),i-Pentane (vpm),n-Pentane (vpm),Ethene (vpm),Propene (vpm),1-Butene (vpm),Carbon-13 d13C-CO2 (per mille VPDB),Carbon-13 d13C-CH4 (per mille VPDB),Deuterium d2H-CH4 (per mille VPDB),Carbon-13 d13C-C2H6 (per mille VPDB),Carbon-13 d13C-C3H8 (per mille VPDB),Carbon-13 d13C-i-C4H10 (per mille VPDB),Carbon-13 d13C-n-C4H10 (per mille VPDB) Methods are described in the accompanying deliverable Fluid data of geothermal sites (type C).

On 10th of May 2021, two thermal water samples were taken by TNO before and after the heat exchanger at the geothermal site Heemskerk in the Netherlands. The samples sent to Hydroisotop were analysed for their hydrochemical composition, heavy metal and dissolved organic carbon (DOC) content and stable isotopes (18O, 2H, 13C-DIC). It should be noted that the pH measured in the laboratory diverges from previously observed pH values which in the past have not been reported below 5,4. Concentrations of major ions had initially been reported too low but re-measurement of the samples yielded values in ranges that had previously been recorded. However, the concentraton of Lithium is much higher than expected. In order to resolve these uncertainties, the site Heemskerk will be sampled again.

    Description: Abstract
    Description: The main objective of the work package 2 of the REFLECT project is to characterise relevant fluid properties and their reactions for saline fluids (type C). One of the specific goals was to collect fluid samples from several saline fluids from geothermal sites across Europe, determine their properties, and thus contribute to the Fluid Atlas (WP3). Additionally, the REFLECT team will compare those field data with data from lab experiments performed at near natural conditions. Samples of type C fluids were taken from several sites in Germany, Austria, Belgium and the Netherlands. The samples were analysed for major and minor ions, dissolved gases and isotopes. Two thermal water samples were taken by Hydroisotop at the production and injection wells in Insheim on 18th of June 2020. The samples were analysed for their hydrochemical composition, heavy metal and dissolved organic carbon (DOC) content, dissolved gases and stable isotopes of water and gas components (18O, 2H, 34S-H2S, 34S-SO4, 18O-SO4, 13C-DIC, 13C-CO2, 13C-CH4, 2H-CH4). Nitrate and a positive redox potential is present in both water samples when reducing conditions would be expected in a deep geothermal well. On-site measurements showed no oxygen present. It is however possible that air contamination during sampling caused some ammonium to oxidize to nitrate. The dataset contains analysis results associated with the research project REFLECT. It is a comma separated file (csv) containing the following columns: Location,Country,Description,Laboratory (Lab.),Lab. No.,Sampling date,Temperature at sampling (degC),Spec. electr. conductivity (25 degC) at sampling (muS/cm),Spec. electr. conductivity (25 degC) Lab.

    Description: Project summary: The efficiency of geothermal utilisation largely depends on the behaviour of fluids that transfer heat between the geosphere and the engineered components of a power plant. The Horizon 2020 funded project REFLECT aims to avoid problems related to fluid chemistry rather than treat them. Fluid physical and chemical properties are often poorly defined, as in situ sampling and measurements at extreme conditions have proved difficult to date. Therefore, large uncertainties in current model predictions prevail, which are being tackled in REFLECT by collecting new, high-quality data in critical areas. The data is being implemented in a European geothermal fluid atlas and in predictive models to allow recommendations on how to best operate geothermal sites sustainably and to enhance geothermal technology development.

    Dissolved organic compounds in geothermal fluids used for energy production – part II (2023)
    GFZ Data Services
    Details
    Publication Date: 2023-04-27
    Description: Abstract
    Description: This dataset comprises 47 fluid samples from 11 geothermal sites (Germany, Austria, Iceland, Turkey, Netherlands, Belgium, French West Indies). The samples were collected within the REFLECT project (Redefining geothermal properties at extreme conditions to optimize future geothermal energy extraction). The focus with these analyses were on the organic compound composition of the fluids, since they are rarely included in the analyses of fluids taken from geothermal power plants. Understanding the organic compound composition of geothermal fluids might help to better understand chemical reactions within the fluids and might help to mitigate problems that arise with the operation of a geothermal power plant such as mineral precipitation (scaling) and corrosion of the casing and pipes.
    Description: Methods
    Description: The samples were taken by the onsite project partners and sent to GFZ for the analyses. Generally, the fluid samples were taken at the surface instalments and remained untreated after sampling (otherwise given as remark in the datasheet). Sampling bottles were rinsed and flushed with the fluids prior to filling them up. Sampling volumes ranged from 250-500 ml per sample.

    Medial moraine cosmogenic 10Be data and glacier surface velocities from four Swiss valley glaciers around Pigne d’Arolla (2023)
    GFZ Data Services
    Details
    Publication Date: 2023-12-20
    Description: Abstract
    Description: At valley glaciers, rockwall erosion supplies debris to glacier surfaces. Once deposited on the ice, rockwall debris is passively entrained and becomes part of the glacial system, e.g., forming medial moraines as downglacier transport continues. Where debris occurs supraglacial, it modifies ice ablation and, thus, changes in rockwall erosion and debris supply rates modify glacial debris cover and mass balance and may affect glacier retreat in response to climate change. Yet, estimates on rockwall erosion rates close to glacier surfaces are few and quantifying spatiotemporal supply patterns is not trivial. This data publication is supplementary to the study on rockwall erosion rates at five Swiss valley glaciers around Pigne d’Arolla, by Wetterauer & Scherler (2023). We temporally and spatially assess rockwall erosion by measuring in situ-produced cosmogenic 10Be concentrations ('[10Be]measured') in medial moraine debris, which we systematically sampled along downglacier-profiles, and by comparing records from various medial moraines, which are supplied by rockwalls differing in exposure and morphology. However, as '[10Be]measured' within supraglacial debris is the sum of '[10Be]rockwall', accumulated during rockwall erosion, and '[10Be]transport', accumulated during post-depositional downglacier transport, medial moraine '[10Be]measured' should be corrected for '[10Be]transport'. If glacier velocities through time are known, '[10Be]transport' can be estimated by downglacier debris trajectory modelling. Providing our 10Be dataset and ~40-year records of glacier surface velocities from four of the five valley glaciers (Glacier du Brenay, Glacier de Cheilon, Glacier de Pièce, Glacier de Tsijiore Nouve) is the main objective of this data publication. The dataset of the fifth glacier (Glacier d’Otemma) has already been published as case study by Wetterauer et al. (2022a,b).

    Radiometric Dates from the South American Andes and Adjacent Areas: A Compilation - part 2 sedimentary rocks (2022)
    GFZ Data Services
    Details
    Publication Date: 2024-02-02
    Description: Abstract
    Description: A compilation of 90,688 published radiometric dates for sedimentary rocks from the South American Andes and adjacent parts of South America have been tabulated for access by researchers via GEOROC Expert Datasets. The compilation exists as a spreadsheet for access via MS Excel, Google Sheets, and other spreadsheet applications. Initial igneous compilations were utilized in two publications by the author, Pilger (1981, 1984). The compilations have been added to in subsequent years with the metamorphic and sedimentary compilations separated in the last few years. Locations in latitude and longitude are largely taken from the original source, if provided, with UTM locations maintained and converted; in some cases, sample locations were digitized from electronic maps if coordinates were otherwise not available. Analytical results are not included to prevent the files from becoming too large. The existing compilation incorporates compilations by other workers in smaller regions of the Andes. References to original and compilation sources are included. While I am updating reconstructions of the South American and Nazca/Farallon plates, incorporating recent studies in the three oceans, for comparison with the igneous dates for the past 80 m. y., it is hoped that the spreadsheets will be of value to other workers. Reliability: In most cases the data have been copy/pasted from published or appendix tables. In a few cases, the location has been digitized from published maps; the (equatorial equidistant) maps were copied into Google Earth and positioned according to indicated coordinates, with locations digitized and copied/pasted into the spreadsheet. (It is possible that published maps are conventional Mercator-based, even if not so identified, rather than either equatorial equidistant or Universal Transverse Mercator; this can be a source of error in location. For UTMs, the errors should be minor.) Duplicates are largely recognized by equivalent IDs, dates, and uncertainties. Where primary sources have been accessed, duplicate data points in compilations are deleted. (Analytic data are NOT included.) This compilation is part of a series. Companion compilations of radiometric dates from igneous and metamorphic rocks are available at https://doi.org/10.5880/digis.e.2023.005 and https://doi.org/10.5880/digis.e.2023.007, respectively.

    Description: Abstract
    Description: This database contains mineral major and trace element compositions of gabbroic rocks composing the lower oceanic crust accreted at the East Pacific Rise and recovered at Hess Deep during IODP Leg 345 (Gillis et al., 2014a). Hess Deep is located at 2°15’N, 101°30’W in the Pacific Ocean, at the western tip of the Cocos-Nazca spreading centre, a westward-propagating oceanic ridge that progressively opens the oceanic lithosphere formed at the adjacent East Pacific Rise (Fig. 1a; Searle and Francheteau, 1986; Karson et al., 2002). Hess Deep is an East-West trending intraoceanic rift reaching 5200 mbsl (metres below sea level) at its deepest point (Fig. 1b,c). It is a tectonic window exposing a complete section of 1.3 Myr oceanic crust accreted at the fast-spreading East Pacific Rise (~130 mm/yr; Rioux et al., 2012; Rowan and Rowley, 2014), ranging from pillow basalts to sheeted dikes, isotropic gabbros, layered gabbros and troctolites, and upper mantle peridotites (e.g., Francheteau et al., 1990, 1992; Hekinian et al., 1993; Lissenberg et al., 2013). The gabbroic rocks included in this database are primitive in composition and range from olivine-rich troctolites to troctolites, olivine gabbros, olivine gabbronorites and gabbros.
