title: In-situ Raman spectra from Na2ATP solutions with starting pH 3 and 7 at 80,100 and 120 °C for determination of the hydrolysis rate constant of ATP

description: Extremophiles maintain an active metabolism up to 122 °C (Takai et al. 2008). These extreme conditions are found, for example in hot springs, in deep oceanic and crustal sediments and in hydrothermal vents at mid-oceanic spreading ridges (Edwards et al., 2011; Heuer et al., 2020). Several studies have investigated the diversity of microorganisms and their relationship to the geological environment as well as to responses to changes. However, the physicochemical parameters necessary to sustain metabolism under these conditions, including the stability of essential molecular compounds like adenosine triphosphate (ATP) and adenosine diphosphate (ADP) have been only studied marginally. 
 
Adenosine triphosphate and adenosine diphosphate are essential energy stores in all currently known metabolic systems. In living cells, the energy is released by the enzymatically controlled exergonic hydrolysis of ATP to power other vital endergonic processes. The abiotic hydrolysis of ATP is kinetically enhanced at elevated temperatures and low pH values resulting in a very short lifetime of ATP and ADP in aqueous solutions (Hulett 1970; Khan and Mohan 1974; Leibrock et al. 1995). Therefore, the kinetic stability of ATP plays a crucial role in metabolism at extreme temperatures. This aspect has been proposed as a critical factor in determining the limits of living cells (Bains et al. 2015). 
 
This data publication compromises all Raman spectra obtained for solutions of Na2ATP with an initial pH of 3 and 7 at 80 °C, 100 °C and 120 °C and for solutions of Na2ADP with initial pH 5 at 100 °C and 120 °C. A hydrothermal diamond anvil cell (HDAC) coupled to a Raman spectrometer was used for in-situ measurements. Pressure was estimated from the vapor-liquid curve of water. In addition to the Raman spectra, the following data are provided: an assignment of peaks in the fitted spectral range, the initial fit parameters, and the fit results.

title: Drone-based photos, 3D models, DSM and orthomosaics and ground-based catalogues of lava fountain times, shape, and amplitude during the Geldingadalir 2021 eruption, Iceland

description: The Geldingadalir 2021 eruption in Iceland started on 19 March and ended on 18 September. It featured nearly 9000 lava fountain episodes of minute to day duration that were all accompanied by seismic tremor. We measured the duration, repose time, tremor amplitude and shape using seismometers from the University of Potsdam. We publish the corresponding catalogs that contain information about these episodes. Periodically, aerial surveys were conducted by the University of Iceland using unoccupied aerial systems (UAS). These surveys lead to digital surface models (DSM), orthomosaics, and 3D models. These products were used to supplement the seismic observations.

title: 3D Earth structures for glacial-isostatic adjustment models

description: We provide 18 3D Earth structures on a global grid. This supplementary material of the manuscript includes (1) 18 netcdf files of the 3D Earth structures and (2) 72 figures that visualize the lithospheric thickness, lateral average viscosity of the asthenosphere, transition zone and upper mantle for all 18 3D Earth structures. The Earth structures were derived from seismic tomography models (Schaeffer & Lebedev 2013, 2010 update of Grand 2002) and, under consideration of geodynamic constrains, transferred to viscosity (Steinberger 2016, Steinberger & Calderwood 2006). The 18 Earth structures vary in conversion from seismic velocity to viscosity. Detailed description of the procedure can be found in the corresponding manuscript (Bagge et al. 2020a), where the Earth structure data were applied to the glacial-isostatic adjustment model VILMA (Klemann et al. 2008, 2015, Martinec et al. 2018) to predict the relative sea-level during the last deglaciation. The netCDF files are provided on a Gaussian grid of 256x512 grid points. Each Earth structure consist of 167 layers, while lateral variations in Earth structure are considered for 114 layers between surface and 870 km depth and radially symmetric layers are considered for 50 layers from 870 km to the Earth’s core. The Earth structure is given as logarithmic viscosity in log10[Viscosity(Pa s)]. To visualize the global 3D structures, we calculated the lithospheric thickness and average viscosity of the asthenosphere, upper mantle and transition zone. The lithospheric thickness is defined as minimum depth with a viscosity &lt; 10^23.5 Pa s, the asthenosphere is defined between the base of the lithosphere and 225 km depth, the upper mantle between 225 km and 410 km and the transition zone between 410 km and 670 km depth.

title: Major and trace element concentrations in hydrological Critical Zone compartments in the Conventwald (Black Forest, Germany)

description: This dataset contains element concentrations of six different hydrological compartments sampled on a daily basis over the course of one year in two neighboured first order headwater catchments located in the Conventwald (Black Forest, Germany). Critical Zone water compartments include above-canopy precipitation (bulk precipitation including rainwater, snow and fog water), below-canopy precipitation (throughfall), subsurface flow from three distinct soil layers (organic layer, upper mineral soil, deep mineral soil), groundwater, creek water and spring water. Element concentrations include major elements (Ca, K, Mg, Na, Si, S), trace elements (Al, Ba, Cr, Cu, Fe, Li, Mn, P, Sr, Zn), anion (Cl), and dissolved organic elements (DOC, DON). 
 
The data were used to explore concentration (C) - discharge (Q) relationships and to calculate short-term element-specific chemical weathering fluxes, which were compared with previously published long-term element-specific chemical weathering fluxes. The ratio of both weathering fluxes, described by the so-called “Dissolved Export Efficiency” (DEE) metric revealed deficits in the stream dissolved load. These deficits were attributed to colloid-bound export and either storage in re-growing forest biomass or export in biogenic particulate form. 
 
Tables supplementary to the article, including data quality control, are provided in .pdf and .xlsx formats. In addition, data measured in the course of the study are also provided as machine readable ASCII files.

title: Seismic data, seismic crustal velocity and anisotropy models for Sri Lanka

description: The data present the intermediate to final results when we introduce a two-step fully Bayesian approach with coupled uncertainty propagation for estimating crustal isotropic and radial anisotropy models using Rayleigh and Love dispersion data along with receiver functions in Sri Lanka. 
 
In the first step, 2D surface wave tomography is used to generate period-wise ambient noise phase velocity maps for Rayleigh and Love waves along with their associated uncertainties. Here we provide the inter-station dispersion data (folder: 2024-003_1_Ke-et-al_interstation_surface_ dispersion_curves; ASCII) for the 2D surface wave tomography process, along with the results of the tomography, including the velocity maps (folder: 2024-003_Ke-et-al_2_velocity_map; ASCII). In addition, the results (folder: 2024-003_3_Ke-et-al_2Dmcmc_inversion_results) are available in MAT format, along with a MATLAB script to allow users to extract the data independently. 
 
In a second step, local surface wave dispersion and model errors are derived from the velocity maps. The surface wave dispersion receiver functions are jointly inverted to obtain the isotropic mean shear wave and radial anisotropy profiles as a function of depth at each station site. The input data (folder: 2024-003_Ke-et-al_4_inv_data; ASCII) of surface dispersion and receiver function for the inversion are presented here, as well as the final result model from the inversion (folder: 2024-003_Ke-et-al_5_model; ASCII and .dat formats).

title: Superconducting Gravimeter Data from Serrahn - 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 SG site “Serrahn” is located in the TERENO Observatory in the nort-eastern German lowlands. The observatory contributes to investigating the regional impact of climate and land use change. At the IGETS site Serrahn, the mean annual temperature is 8.8 °C and mean annual precipitation is 591 mm. The land cover is mainly characterized as a mixed forest, dominated by European beech and Scots pine. Influenced by the last glaciation in an outwash close to the terminal morraine, the uppermost soil layer of the site consists of aeolian sands up to a depth of 450 cm, followed by coarser sandy material with intercalated till layers. The unconfined groundwater level is at about 14 m below surface. There is hardly any human activity (e.g., traffic) at this quiet forest site. The nearest town is Neustrelitz at a distance of 5 km. 
 
Since December 2017, the superconducting gravimeter iGrav-033 is operated outdoors at this forest location (Latitude: 53.3392 N, Longitude: 13.17413 E, Elevation: 79.60 m). The gravimeter is installed in a dedicated field enclosure on top of a concrete pillar with an area of 1.1 m x 1.1 m at an elevation of 0.80 m above the terrain surface. The pillar has been build to a depth of 2.00 m below the surface. One additional pillar (also 1.1 m x 1.1 m, at surface level) is located right next to the iGrav installation and is used for repeated observations with absolute gravimeters (AG). 
 
At the site, meteorological (precipitation, air temperature, humidity, air pressure) and hydrological (groundwater, soil moisture, sapflow, throughfall) parameters are monitored by different sensors. Raw gravity and local atmospheric pressure records sampled at second intervals and the same records decimated at 1‐minute samples are provided as Level 1 products to the IGETS network.

title: Superconducting Gravimeter Data from Helgoland - 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) between 1997 and 2015 to provide support to geodetic and geophysical research activities using superconducting gravimeter (SG) data within the context of an international network. As part of this network, the Helgoland Gravimetric Observatory Germany (HELGOG) was established by the GFZ German Research Centre for Geosciences in March 2020. Continuous time-varying gravity and atmospheric pressure data from the iGrav SG at HELGOG are integrated in the IGETS data base hosted by GFZ. HELGOG is located in the basement of the Biological Institute Helgoland (BAH) of the Alfred Wegener Institute (AWI), Helmholtz Centre for Polar and Marine Research. The operation and maintenance of the HELGOG instrumentation is jointly done by staff of AWI and GFZ. The iGrav SG is directly installed on the concrete floor of the basement. The distance from the iGrav SG to the North Sea is only 10 m. Being located at sea level (H=2.059 m), the iGrav SG is predominantly sensitive to vertical displacements. Helgoland is Germany’s only island in the open sea 50 km away from the mainland. The gravimetric observations enable the analysis of ocean tides and non-tidal mass redistributions, especially in connection with storm surges in the North Sea (see also Weise et al. 2020). Next to the iGrav SG, there is space for absolute gravimeters (first measurements in July 2020 by Ludger Timmen from Leibniz Universität Hannover) and other instruments. The nearby continuous Global Navigation Satellite Systems (GNSS) stations HELG and HEL2 are operated by BKG (Federal Agency for Cartography and Geodesy). HELGOG is also part of the Observation Platform Helgoland including seismometers, infrasound, spring gravimeters and tiltmeters. HELGOG is equipped with the iGrav SG 047 manufactured by GWR Instruments. The time series of gravity and barometric pressure from the iGrav SG 047 starts in March 2020. The SG is active and the time series is kept up to date regularly with a time delay of a few months. The time sampling of the raw gravity and barometric pressure data of IGETS Level 1 is 1 second and 1 minute. For a detailed description of the IGETS data base and the provided files see Voigt et al. (2016, http://doi.org/10.2312/GFZ.b103-16087).
