title: The gravimetric quasi-geoid of Paracel Islands: PIGEOID2021

description: PIGEOID2021 is a purely gravimetric quasi-geoid model covering the whole Paracel Islands in the northwestern South China Sea. The quasi-geoid is referred to the GRS80 ellipsoid and extends from 15.27°N to 18.23°N and from 110.59°E to 113.30°E with a grid spacing of 30" in both the latitudinal and longitudinal directions. PIGEOID2021 is computed using localised airborne gravity anomalies (with an accuracy of 1.44 mGal at a resolution of 3 km) under the framework of the remove-compute-restore method, where XGM2019e_2159 (truncated to d/o 1080) is used as the reference model and the residual terrain model is applied for smoothing local gravity field at very short scales (&lt; 3 km). The residual gravity field is parameterized using Poisson wavelets by assuming white noise of observations. Comparisons with altimeter-derived geometric quasi-geoid heights retrieved from Jason-2, CryoSat-2, and SARAL show the misfits of PIGEOID2021 are within 5 cm. Further analysis shows PIGEOID2021 reduces the bubble-like errors over island areas by a magnitude exceeding 6 cm compared to existing global geopotential models. 
 
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.

title: GRACE-FO calibrated and characterized magnetometer data

description: GRACE-FO carries a magnetometer as part of its attitude orbit control system (AOCS). The magnetometer does not belong to the scientific payload of the mission. However, after postprocessing of the data, information on the geomagnetic field and on electric currents in near Earth space are derived. Each GRACE-FO satellite (GF1 and GF2) carries two fluxgate magnetometers (FGM), an active one, FGM A, and a redundant one, FGM B. So far, the redundant magnetometers were not switched and are not included in the data set. The provided data consists of raw magnetic field data as provided by L1b (RAW), Magnetic field data aligned, calibrated and corrected (ACAL_CORR), CHAOS7 magnetic model predictions for core, crustal and large-scale magnetospheric field (CHAOS7), Magnetic coordinates (APEX) and Radial and field-aligned currents derived from magnetic data in ACAL_CORR (FAC). The data are provided in NASA CDF format (https://cdf.gsfc.nasa.gov/).

title: CH-ME-2-FGM-SCI - CHAMP 50 Hz Magnetic Field Vector Time Series in Sensor- and ECEF-(NEC)-System (Level 2)

description: Earth's magnetic field vector time series from `LEO' satellite 'CHAMP' for the 'CHAMP' mission period in high, unaveraged 50 Hz time resolution, using measurements from the FGM vector magnetometers and `ASC' Star Sensors on the mid-boom optical bench. The vector data are corrected and calibrated (by using the Overhauser scalar magnetometer as reference). The magnetic field vector data are given both in the satellite-bound sensor (`FGM') system and in the Earth Centered Earth Fixed local `NEC' (North-East-Center) system. For the latter the attitude time series (`ASC'), processed and cleaned, represented by quaternions describing the satellite attitude related to the celestial system, were used for the transformation. The files with daily time coverage are in the (binary and self-describing) `CDF' file format and accompanied, beside the `CDF'-format generic timestamp, by the satellite's geocentric positions and utility information like quality flags. The full product and format descriptions are provided in the associated Scientific Technical Report - Data (GFZ Section 2.3, 2019. http://doi.org/10.2312/GFZ.b103-19104).
description: CHAMP (CHAllenging Minisatellite Payload) was a German small satellite mission for geoscientific and atmospheric research and applications, managed by GFZ . With its highly precise, multifunctional and complementary payload elements (Overhauser scalar magnetometer (OVM) and Fluxgate vector magnetometer (FGM), accelerometer, star sensor (ASC), GPS receiver, laser retro reflector, ion drift meter) and its orbit characteristics (near polar, low altitude, long duration) CHAMP generated highly precise gravity and magnetic field measurements simultaneously for the first time and over a 10 years period.

title: Results of non-metric Multidimensional scaling (NMDS) based on Bray Curtis dissimilarity of organic matter molecular compositions of purple glacier ice- and red snow-algae dominated surface samples collected close to the QAS-M Promice weather station on the southern tip of the Greenland Ice Sheet.

description: These datasets display the results of multivariate statistical analysis non-metric multidimensional scaling (NMDS) based on Bray Curtis dissimilarity of the organic matter (OM) molecular compositions of surface glacier purple ice- and red snow-algae dominated samples collected on the Greenland Ice Sheet at ca. 61°1’ N,46°8’ W (Rossel et al., 2025). The molecular compositions of the samples were obtained by ultrahigh resolution analysis on a 15 Tesla Fourier transform ion cyclotron resonance mass spectrometer (FTICR-MS, Rossel et al., 2025). All reported NMDS datasets display the molecular loadings and samples scores for the first two axes of the NMDS (NMDS1 and NMDS2), the number occurrences of each molecular formula per sample type, and molecular properties of the formulae such as: mass (MWwa), hydrogen/carbon (H/Cwa) and oxygen/carbon (O/Cwa) ratios, aromaticity index (AI-modwa), double bond equivalents (DBEwa) and DBE minus oxygen (DBE-Owa), Nominal oxidation state of carbon (NOSCwa) and the molecular category the formula was assigned (Aromatics, Condensed aromatics, highly unsaturated, unsaturated aliphatics and saturated). Furthermore, the NMDS datasets are separated according to the compared sample set. In the first NMDS analysis (Table S1, Fig 1 in Rossel et al., in review), we compared all samples: the initial OM from glacier ice- (T0_Ice) and snow-algae (T0_Snow) dominated habitats and the up to 24 days (T3-T24) in situ incubated samples under dark (D) and light (L) conditions. These OM samples, include both dissolved organic matter (DOM) and particulate organic matter (POM), the latter extracted with hot water (HW) and sodium hydroxide (Na) to represent water-soluble and particle-associated OM, respectively (see methods). In the second and third NMDS analyses, we compared DOM and POM samples separated (Table S2 and Table S3, respectively). Following the separation of all analyzed samples in the first NMDS (purple and red samples in Fig 1 in Rossel et al., in review), OM molecular signals related to glacier ice-algae (Table S4) and snow-algae (Table S5) were separated using NMDS1 values ≤ 0.45 and ≥ 0.45, respectively (Fig. 1b and Fig. 1c in Rossel et al., in review). Additionally, these separated molecular signals for glacier ice-algae and snow-algae samples were used to calculate intensity weighted (subscript wa) values for MWwa, H/Cwa and O/Cwa ratios, AI-modwa, NOSCwa, DBEwa and DBE-Owa for each sample (Table S6).

title: Normalized peak intensities obtained from the molecular analysis of organic matter from purple glacier ice- and red snow-algae dominated surface habitats collected close to the QAS-M Promice weather station on the southern tip of the Greenland Ice Sheet

description: This dataset provides molecular formulae with their normalized mass peak intensities obtained from ultrahigh resolution mass spectrometric analysis of organic matter (OM) from glacier purple ice- and red snow-algae dominated samples collected upwind of the DEEP PURPLE ice camp (deeppurple-ercsyg.eu) on the surface of the Greenland Ice Sheet. The samples are represented by the initial OM from glacier ice- (T0_Ice) and snow-algae (T0_Snow) dominated habitats and the up to 24 days (T3-T24) in situ incubated samples under dark (D) and light (L) conditions. OM samples, include dissolved organic matter (DOM) and particulate organic matter (POM), the latter extracted with hot water (HW) and sodium hydroxide (Na) to represent water-soluble and particle-associated OM, respectively (see methods). Molecular analyses were performed on a Solarix Fourier transform ion cyclotron resonance mass spectrometer (FTICR-MS) equipped with a 15 Tesla superconducting magnet (Bruker Daltonic) using an electrospray ionization source (ESI, Bruker Apollo II) in negative ion mode on DOM samples and POM extracts previously solid phase extracted (SPE, Dittmar et al., 2008). Molecular formula calculation for all samples was performed using the software ICBM-OCEAN (Merder et al., 2020) and include the following combination of elements: C0-100, O0-50, H0-200, N0-4, S0-2 and P0-1 (the full description of the data and methods is provided in the data description file). Because DOM and POM samples were analyzed in duplicates in the mass spectrometer, a compound was considered to be present if it appeared in both duplicate measurements. The mean normalized intensity of duplicate measurements is presented here and was further used for statistical analysis in Rossel et al., to be submitted. This dataset contains 8827 molecular formulae with their normalized peaks intensities.

title: Dissolved organic carbon concentrations from the dissolved organic matter (DOM) and extracted particulate OM (POM) obtained from purple glacier ice- and red snow-algae dominated surface habitats collected close to the QAS-M Promice weather station on the southern tip of the Greenland Ice Sheet

description: This dataset provides the dissolved organic carbon (DOC) concentrations of the organic matter (OM) obtained from glacier purple ice- and red snow-algae dominated samples collected upwind of the DEEP PURPLE ice camp (deeppurple-ercsyg.eu) on the surface of the Greenland Ice Sheet. The samples are represented by the initial OM from glacier ice- (T0_Ice) and snow-algae (T0_Snow) dominated habitats and the up to 24 days (T3-T24) in situ incubated samples under dark (D) and light (L) conditions. OM samples, include dissolved organic matter (DOM) and particulate organic matter (POM), the latter extracted with hot water (HW) and sodium hydroxide (Na) to represent water-soluble and particle-associated OM, respectively (see methods). Dissolved organic carbon concentrations were determined as non-purgeable organic carbon obtained from replicate measurements of DOM and POM extracts analyzed in a Shimadzu high-sensitivity TOC-V analyzer. The concentrations in this dataset are part of the supplementary material in Rossel et al. (2025).

title: Microprobe measurements of PGM, pristine and secondary phases of samples of the Merensky Reef, Bushveld Complex, South Africa

description: Platinum-group elements (PGE) in the Bushveld Complex (South Africa) are mainly recovered from pristine, unweathered ores of the Merensky Reef, UG-2, and the Platreef. Weathered PGE ores are currently not mined due to uneconomic recovery rates achieved by conventional metallurgical methods although weathered ores can contain a high PGE content. In order to understand the behavior of PGE during weathering, five drill cores containing fresh and weathered Merensky Reef (originating from the Twickenham and Richmond properties of AngloPlatinum in the eastern Bushveld Complex), were studied by microprobe. Polished thick section of the samples with high PGE content was created and then analyzed after microscopic evaluation of the most promising section (with a high platinum-group mineral (PGM) content) In the pristine ores, the PGM occur dominantly as sulfides, arsenides, and tellurides. They are mainly found in contact or close to base metal sulfides (BMS). In the oxidized ores, discrete, relict PGM are rare, indicating remobilization of the PGE during weathering. Microprobe data reveal traces of PGE within secondary minerals (e.g. Fe-hydroxides, chlorites etc.).

title: Sensitivity of boron adsorption on clays to changes in seawater chemistry

description: The adsorption of boron on detrital particles like clay or metal oxides is thought to be a major mechanism driving changes in the boron isotopic composition of seawater on geologic timescales. However, the sensitivity of adsorption parameters to long-term changes in the seawater concentration of major ions (Mg2+, Ca2+, SO42-) and dissolved inorganic carbon (HCO3-, CO32-) is not known. We conducted multiple sets of adsorption experiments that consist of suspending pretreated clay minerals (either kaolinite, smectite or illite) in artificial seawater with a modified chemical composition. Specifically, we investigate adsorption in seawater with a major ion composition resembling that of the Cretaceous (100 Ma) and the Eocene (50 Ma), as well as modern seawater with either reduced or elevated concentrations of dissolved inorganic carbon. We finally combine the results with modeled values for the mineral assemblage of detrital sediment to constrain boron adsorption fluxes in the past. The dataset consists of two sheets that store (1) the results of our adsorption experiments and (2) the modeled sediment properties. 
 
Experiments were performed on KGa-1b kaolinite, SWy-3 smectite and IMt-2 illite obtained from the Clay Mineral Society. For each of these clays, a consistent particle size fraction of 2 – 0.2 μm was extracted by repeated centrifugation and decantation. As a result, clay samples used in the experiments have a high mineralogical purity of 95% (in the case of kaolinite and illite) and 50% (in the case of smectite). 
Pretreated clays were submerged in one of four different boron-containing artificial seawater solutions. These seawater solutions were prepared by mixing trace element-grade salts with ultrapure water according to the recipe of Millero (2013). Specifically, the amounts of added MgCl2, CaCl2, Na2SO4 and NaHCO3 were varied to produce four different seawater stock solutions that have (i) a major ion concentration similar to Eocene seawater; (ii) a major ion concentration similar to Cretaceous seawater; (iii) a DIC concentration half as high as in modern seawater; (iv) a DIC concentration twice as high as in modern seawater. Clay and seawater were allowed to interact for 48h through continuous agitation, after which solution samples were extracted.

title: Lithogeochemistry of the Volcanic-Sedimentary Complex and major and trace element contents in apatite from the Neves Corvo Cu-Zn-Pb(-Sn) deposit (Portugal)

description: Analyzing the chemical composition of rocks and minerals is an important tool for exploring and understanding mineral resources. The Neves Corvo Cu-Zn-Pb(-Sn) is one of the richest volcanogenic massive sulfide deposits in the work and is unique within the Iberian Pyrite Belt (IBP) in terms of size, Cu-Zn grades and tonnages, the notable occurrence of Sn mineralization (Relvas et al., 2001) and In and Se contents (Carvalho et al., 2018). The mineralization occurs in close association with felsic volcanic rocks and black shale, where three main types are defined: (1) stringer and massive cassiterite mineralization, (2) stockwork and massive sulfide mineralization, and (3) late tectonic-metamorphic remobilization. The Sn mineralization is structurally controlled and occurs along the so-called “tin corridor” in the Corvo orebody (e.g., Relvas et al., 2006a, 2006b). 
 
We analyzed major, minor and trace element contents of the footwall metavolcanic and metasedimentary units by XRF, ICP-MS and ICP-OS. This data publication reports for the first-time apatite major, minor and trace element compositions by microprobe and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) and Raman Spectroscopy, and microprobe analyses from florencite and xenotime, in previously characterized samples from the Corvo orebody (Relvas 2000 and Relvas et al. 2001, 2006a, 2006b).

title: In situ EMPA and SIMS investigation of mineral geochemistry of mantle xenoliths from Cerro Nemby (25°24' S, 57°32' W), Paraguay

description: Mantle xenoliths are hosted in lavas localized in the Nemby area (25°24' S, 57°32' W; Asunciòn-Sapucai-Villarrica graben, ASV, central Paraguay: Fig.1), where a small melanephelinitite plug (Cerro Nemby), with elliptical topography (800 x 500 m, about 100 m above the plain), contains very abundant mantle xenoliths (10-15% by volume of the plug) together with crustal xenoliths (Comin-Chiaramonti et al., 2001). 
According to Le Bas (1987), lavas consist of nephelinite and subordinately of ankaratrite (CIPW Ab &lt; 5 wt% e Ne &gt; 20 wt%). 
The average size of the mantle xenoliths (10-12 cm, max 45 cm, i.e. the largest observed in ASV) and the compositional range (lherzolite to dunite to pyroxenite) make these xenoliths particularly suitable for a study regarding metasomatic processe(s) affecting the Sub-Continental Lithospheric Mantle of central Paraguay. 
The dunite results to be the most abundant xenolith type in such lavas. In-situ geochemical characterization was performed on silicates and glasses from very fresh xenoliths, which document a large variety of rock types. Five samples were investigated, namely: i) dunite 3209; ii) spinel harzburgite 3284; iii) spinel lherzolite 3293; iv) olivine websterite 3253 and v) olivine clinopyroxenite 3270. The analyses were directly carried out on thin petrographic sections (30 µm thick) of the selected samples.

title: In situ trace elements and U–Pb ages determination of zircons from diorite and anorthosite dykes intruding the Finero Phlogopite Peridotite (Ivrea-Verbano Zone, Southern Alps)

description: Zircon grains were separated from diorite and anorthosite dyke swarms intruding the mantle body of Finero Phlogopite Peridotite (Northernmost tip of the Ivrea-Verbano Zone, Southern Alps). All the dykes are highly discordant with respect to the mantle peridotite foliation and crop out along the right flank of the Rio Creves valley (Piedmont, Italy). The dykes are characterized by similar mineralogical composition, but show widely variable modal proportions.

title: In situ EMPA and LA-ICP-MS chemical analysis of mantle xenoliths from Sierra Baguales (50°S), Patagonia

description: The Patagonia is a vast region located in the southernmost tip of the South America continent. It shows a basaltic plateau formed by volcanic activity started in the Upper Cretaceous-Lower Cenozoic (e.g., Baker et al. 1981; Ramos et al. 1982) and continued during Plio-Quaternary period. Long this time, the basalts have changed their compositions due to a variation in the tectonic environments. 
 
We studied mantle xenoliths hosted in the Plio-Quaternary alkaline basalts from Sierra Baguales, which are related to the back-arc environment (Munoz and Stern 1988, 1989; Munoz et al. 1989). Samples are recognized in two different areas (i) Cerro del Fraile and (ii) Cono Sin Nombre, which are situated to the NW and SE with respect to Sierra Baguales, respectively.
