EAlpG - European Alps Geoid
Európsky Alpský geoid
| Duration: | 1. 1. 2022 - 31. 12. 2027 |
| Program: | Multilaterálne - iné |
| Project leader: | Mgr. Zahorec Pavol PhD. |
| Annotation: | The Global Navigation Satellite Systems (GNSS) have caused a fundamental and lasting change in the field of Geodesy. Due to the missing link to the gravity field of the Earth, GNSS measurements yield purely geometric heights relative to a reference ellipsoid. To derive physical heights, additional information is necessary that describe the undulations of the height reference surface. This information is computed from global or regional gravity field models and is denoted as geoid or quasigeoid models. The combination of GNSS measurements and geoid models provides an efficient tool to determine heights. However, it does not reach the accuracy of the traditional leveling methods. Height reference systems are therefore still measured on a national basis and by the use of precision leveling. The national height reference systems differ regarding the definition (height type), the applied numerical standards as well as the choice of the geodetic datum (zero level). In the geodetic practice this results in different height levels that become most apparent at the national borders, yielding up to about 50 cm (between France and Germany). The cooperation is expected to enable the following achievements: • Harmonization of the underlying data for regional geoid modeling in the border regions of the partnering countries, • Determination of a joint geoid/quasigeoid model in the Alpine region (European Alps Geoid), • Analysis of the datum differences between the national height reference frames of the partnering countries, • Derive appropriate transformation rules between the national height reference frames, • Validation of global and continental gravity field models. |
FAIRNESS - FAIR Network of micrometeorological measurements, Akcia CA20108

| Annotation: | The FAIRNESS action intends to improve standardization and integration between databases/sets of micrometeorological measurements that are part of research projects or local/regional observational networks established for special purposes (agrometeorology, urban microclimate monitoring). Addressing identified challenges requires an effective transboundary network of researchers, stakeholders (extension services and environmental agencies, local authorities and ministries, SME) and civil society (specialized and general public) from Europe and beyond to identify and fill knowledge gaps, standardize, optimize and promote new environmental-tailored measurement and control procedures, enhance research effectiveness and improve dissemination. |
HENRI, H2I-S&D - - Hydrogen Energy Reservoir (IPCEI - important projects of common European interest)
Hydrogen Energy Reservoir (IPCEI-Významný projekt spoločného európskeho záujmu) IPCEI - Important Projects of Common European Interest),

| Evidence number: | SA.64635 |
| Program: | Iné |
| Project leader: | RNDr. Kotulová Júlia PhD. |
| Annotation: | The project goal is to identify both an appropriate location for storing hydrogen mixed with natural gas and the maximum possible concentration that could be stored in a porous geological structure. The first phase of H2I S&D has experts seeking an appropriate location for storing hydrogen mixed with natural gas. Having identified an appropriate underground geological structure, laboratory research is being carried out to define the maximum permitted concentration of hydrogen. A broad spectrum of parameters would be researched, such as possible geochemical and microbial reactions and changes in the rocks. The second phase of the project involves constructing a pilot test of the technology to generate hydrogen through water electrolysis. The hydrogen would then be mixed with natural gas at concentrations defined in the first phase of the project, with the mixture stored in underground facilities. The objective is not one-cycle testing, but rather to test multi-cycle production and injection to obtain more data about the impact and behaviour of hydrogen stored underground, thereby creating a comprehensive image of how it can be stored in specific rock structures. Results from laboratory testing and the models thereby created will also be verified, with the models corrected by real data. |

| Annotation: | The geophysical imaging of crustal structures and its tectonic interpretation is the key instrument for us to better understand and asses the raw materials potential of the Czech and Slovak Republic. The proposed bilateral project contribution dwells in the application and development of an integrated modelling methodology, i.e. a combination of magnetotelluric and other geophysical sounding methods for shallow geological structures and its subsequent interpretation for tectonics and connected raw material deposits characterization in selected areas of the Western Carpathians. The Carpathians are characterized by a very diverse and complicated tectonic structure and a diverse range of different mineral deposits, which are linked to tectonic structures and lithological complexes of various ages. Newly collected MT data will be processed and modelled with other available geophysical data to characterize geometries and properties of tectonic structures connected to various mineral deposits in this targeted area. For modelling we will use and test newest joint inversion methodology to obtain improved complex geophysical image with goal to bring additional direct impact on mineral resources utilization. |

| Evidence number: | ERA-MIN 2/2020/1102/D-Rex |
| Program: | ERANET |
| Project leader: | RNDr. Vozár Ján PhD. |
| Annotation: | Mineral deposits are a small part of a very large geological context, the so-called mineral system. The first objective of D-Rex is to build onto this new paradigm with geophysical data from three prospective areas in Sweden, Greenland and Finland. Therefore, the second objective of D-Rex is the integration of multi-facetted geophysical data acquired at those prospective areas. The third objective of D-Rex is the unification, optimum integration and visualization of geological and geophysical data on the basis of the Common Earth Modelling (CEM) concept. Key element of the project involves: Electromagnetic (deposit scale) surveys; Development of multimethod 3D modelling/inversion technique; Joint inversion assisted by machine learning techniques to couple different geophysical parameters, to uncover correlations between them as well as their absence; Regional to deposit scale models integration into Common Earth Model based on all available geophysical and geological data; Building predictivity maps based on the regional models; Correlation and interpretation of regional scale together with deposit scale models. The outputs of this project will be novel technologies and workflows that directly address Europe’s goal to become self-sufficient in terms of raw materials. We will achieve an improved understanding of the geological history of key mineral districts in Europe and by proxy also other similar or related European metallogenic zones. This understanding will result in improved models for the formation of minerals and allow us to better predict their expected locations. This will lead to the discovery of new, higher-grade and possibly larger mineral deposits and thus better supply. |

OPENSENSE - Opportunistic precipitation sensing network
Oportunistické formy merania atmosferických zrážok
| Duration: | 13. 10. 2021 - 12. 10. 2025 |
| Evidence number: | CA20136 |
| Program: | COST |
| Project leader: | Mgr. Onderka Milan PhD. |
| Annotation: | Despite advances in remote sensing, precipitation observations remain one of the weakest links in the description of Earth’s water cycle. This is especially critical in the face of climate change, human-induced hydrologic changes e.g. due to rapid urbanisation, and consequent increase in frequency and magnitude of extreme events. Opportunistic sensing can greatly improve spatial and temporal resolution of standard precipitation monitoring networks on continental scale by complementing them with measurements from personal weather stations or devices primarily not intended for precipitation monitoring such as commercial microwave links or broadband satellite terminals. The number of opportunistic sensors has already now exceeded traditional in-situ observations by an order of magnitude, and it is increasing exponentially. Nevertheless, it is still unclear how to make this data operationally accessible, achieve robust quality control of these observations, and integrate them into standard observation systems.OPENSENSE brings together scientists investigating different opportunistic sensors, experts from national weather services, owners of sensor networks, and end-users of rainfall products to build a worldwide reference opportunistic sensing community. It will i) overcome key barriers preventing data exchange and acceptance as hydrometeorological observations ii) define standards to allow for large-scale benchmarking of OS precipitation products developing new methods for precipitation retrieval iii) coordinate integration of the opportunistic observations into traditional monitoring networks, and iv) identify potential new sources of precipitation observations. These coordinated activities will boost uptake of OS as precipitation observation methods and enable generation of high-quality precipitation products with unprecedented spatial and temporal resolution. |
Benchmark experiments and modeling of alloy systems involving flow and solidification

| Program: | Mobility |
| Project leader: | doc. Mgr. Guba Peter PhD. |
| Annotation: | Regions of mixed solid-liquid phases, or so-called mushy regions, play an important role in geology and geophysics. The phase change in the mushy layers is a source of convective motions leading to the redistribution of mass and heat in the solidifying system. A striking consequence is the formation of vertical chimneys through which plumes of buoyant fluid rise. The project aims at understanding the growth of a mushy layer with chimney convection. We will design and conduct a series of benchmark solidification experiments on salt solutions. Theoretical modelling will focus on understanding the factors controlling the convective mushy layer growth and the evolution of its internal structure over a long time horizon. A further aim will be to quantify the convective fluxes between the mush and the molten alloy, which are crucial for macrosegregation. Understanding the above phenomena is vital for the explanation of the origin of the Earth's core convection, magma solidification as well as the mass transport between the shells and subsurface oceans of the icy moons. |

Analysis of special magnetotelluric situations and their manifestations in the electromagnetic response
Analýza zvláštnych magnetotelurických situácií a ich prejavov v elektromagnetickej odozve

| Evidence number: | 2/100/2024 |
| Program: | VEGA |
| Project leader: | RNDr. Marsenić Alexandra PhD. |
| Annotation: | Electromagnetic exploration of the Earth consists in evaluating its response to the action of electromagnetic fields. Magnetotellurics uses variations of electric and magnetic fields, which penetrate to various depths depending on the frequency and conductivity of the subsoil layers. However, the near-surface lateral inhomogeneities distort the expected response, with the magnitude of the distortion depending on the conductivity contrast between the large-scale (surveyed regional) structure and the local disturbing body. This is due to the induction of charges and currents at the interfaces, which become a source of secondary fields. As for the interpretation of the measured data, this is an unpleasant problem, but these fields also carry information about the subsurface structure. It is difficult to model them numerically, as the task requires the establishment of an internal boundary condition. Identifying secondary fields in the response can help to a more reliable interpretation of the measured data. |

| Annotation: | Application of modern approaches of gravimetric inversion and structural density and integrated modelling, supported by additional geophysical and geological methods, to solving selected current problems of crustal and lithospheric structure and its tectonic development, as well as dynamic processes therein. For that sake methods of joint modelling of several geophysical fields and diverse datasets will be adopted, along with gravimetric inversion based on model exploration and growing source bodies of free geometry (the Growth approach). The Growth inversion approach will be applied also to interpretation of spatiotemporal gravity changes. For structural studies interpretation of new geoelectric and MT data, and existing seismic profile data, will be employed. Isotope dating and petrological and geochemical analyses will be utilized also. The determined rheological properties will be incorporated into the structural models to infer tectonic implications. |

| Annotation: | The knowledge of tectonic dislocations (faults) is essential for various areas of economic activity (e.g. large transport constructions, dams, nuclear power plants, mineral exploration and exploration of geothermal waters), and it has an impact on environmental issues (e.g. risks, slope deformations, sites for radioactive waste seismic storage). The systematic processing of data on the dislocations of crust in Slovakia in the form of a comprehensive monograph is highly needed. This is the aim of our DISLOCAT project. Based on the excerption of available published and archived data, all significant tectonic dislocations of crust will be characterized according to uniform criteria. We will focus on the faults from the youngest Neoalpine tectonic development, many of which are still active today. The basic parameters of the faults will include the manifestations of the faults in the geological map and/or aerial and satellite images, its course, inclination and depth, thickness of the disturbed zone, structural data and kinematics, age, seismicity, available geodetic measurements of recent movements, geomorphological manifestations and springs of water or emanations. Great attention will be paid to seismoactive fault zones. The information about selected faults will be collected and made more precise by field research into the geological structure and geophysical, mainly magnetotelluric measurements. |

| Annotation: | Minerals of critical metals (Zr, Nb, Ta, REE) are prospective raw materials that trigger the recent technological progress. These elements are preferably bound to carbonatites, i.e. igneous rocks composed predominantly of carbonates. The overwhelming part of recent knowledge concerns carbonatites in stable cratons. Recently, however, the metallogenetic potential of orogenic carbonatites from tectonic plate junctions has been investigated. These carbonatites are intensely reworked, which affected the behavior of critical elements. The aim of the project is mineralogical, geochemical and geochronological research of selected carbonatite deposits in Mozambique and China in order to identify processes of mobilization, accumulation and disproportionation of critical metals during magma fractionation and superimposed metamorphic, hydrothermal and metasomatic reworking. The main output of the project will be the formulation of criteria for optimizing exploration methods for orogenic carbonatites. |
The monitoring of the geomagnetic field and the study of extreme mid-latitude geomagnetic disturbances
Monitoring geomagnetického poľa a štúdium extrémnych geomagnetických porúch v stredných šírkach

| Evidence number: | 2/0003/24 |
| Program: | VEGA |
| Project leader: | Mgr. Valach Fridrich PhD. |
| Annotation: | Recent case studies of extreme mid-latitude geomagnetic variations have indicated that their primary cause may be the auroral current systems or the field aligned currents connecting the auroral oval to the more distant parts of the magnetosphere. This is inconsistent with the traditional concept of magnetic storms, which says that the main cause of such extreme phenomena is the intensified ring current. The preliminary conclusions of these case studies can only be confirmed, refuted or corrected by an analysis of a larger number of very intense mid-latitude disturbances. Thus the aim of the project is to contribute to the verification of this newly proposed mechanism of the extreme mid-latitude variations by analyzing a larger database of observations. The database will consist of modern digital records available from the INTERMAGNET as well as historical magnetograms from the mid-19th century. The project also contributes to the database extension with our observations at observatory Hurbanovo. |

ALCABA - New Bouguer anomaly map of the Alpine-Carpathian area: a tool for gravity and tectonic applications
Nová mapa Bouguerových anomálií alpsko-karpatskej oblasti: nástroj pre gravimetrické a tektonické aplikácie

| Evidence number: | APVV-19-0150 |
| Program: | APVV |
| Project leader: | Mgr. Zahorec Pavol PhD. |
| Annotation: | Exact calculation of the complete Bouguer anomalies (CBA) plays an important role in applied gravimetry, whereas these serve as the main input into geological, structural and tectonic interpretation (in CBA maps all non-geological influences – mainly the manifestation of relief - are suppresed and the density inhomogeneities in lithosphere structure are displayed). The team of investigators of the submitted project was invited in the frame of an European initiative (AlpArray Gravity Research Group) with the aim to create a new map of CBA from the Alpine-Carpathian area. Up to day published solutions, coming from the so-called „Slovak gravimetric school“ (e.g.: reambulation of gravimetric databases on the national level, calculation of near and distant topographic effects, regularized, transformations of potential fields, 3D complex density modelling with the introduction of the geological corrections, stripping of gravimetric fields) could be further developed and applied during the tectonic interpretation of the new CBA map from the Alpine-Carpathian region with the aim to improve the knowledge about Alpine orogenesis and its relation to the upper-mantle dynamics. As a part of the project, there are planned also verification field measurements, which can contribute to the improvement of the precision of the gravimetrical dataset of the Alpine- Carpathian area. Project has chance to develop the methodics of CBA calculation in high-mountains environment using the concept of ellipsoidal heights and to deliver to other experts an unique new gravimetric map from the region of Western and Central Europe. Main output of the project will be the new CBA map from the Alpine- Carpathian region in a digital format (grid 4x4 km), which will be provided for a realisation of gravimetric, geodynamic, exploration, geothermal and other studies and researches. Additional outputs of the project will be the transformed maps (grids) of CBA field. |

| Annotation: | The project addresses the investigation of radon activity concentration (222Rn) in the atmosphere of selected show caves in Slovakia, using integral and continuous measurements. Long-term integral and short-term continuous monitoring will be performed in the atmosphere of the Brestovská Cave, the Harmanecká Cave and the Demänovská jaskyňa slobody Cave. In the Važecká Cave the continuous monitoring of radon will continue. Periodic and non periodic variation of radon activity concentration will be evaluated in relation to the meteorological parameters measured inside and outside the cave. Radon activity concentration in water collected from lakes and streams in the above mentioned caves will be determined. On the basis of the obtained experimental data a model of seasonal, daily and short-term variations of radon in caves will be proposed and tested, as well as model of their ventilation regime. |
Response of Mountain pine to stress factors in mountain areas of the Western Carpathians
Odozva borovice horskej – kosodreviny na stresové faktory v horských oblastiach Západných Karpát

| Project leader: | Ing. Lukasová Veronika PhD. |
| Annotation: | The communities of Mountain pine (Pinus mugo) fulfill important ecological and environmental functions in mountainous areas. Due to climate changes, these communities are exposed to warming, extreme weather conditions (hot dry summers, warm spells in winters, reduced snow periods and snow cover) and high surface ozone (O3) concentrations, which affects their condition. The project presents a comprehensive approach to assess the biological response of P. mugo communities to stress factors (O3 concentration and bioclimatic conditions) evaluated by the normalized difference vegetation index (NDVI), oxidative stability (OxSt) and the visible injury index (VII) of assimilation organs. The use of NDVI derived from satellite data which reflects the amount of chlorophyll in plant tissues; provides the possibility to analyze the damage in a large scale. Presented project is highly topical and responds to the requirements of the European Commission for the conservation of biodiversity in the context of climate change. |

| Annotation: | The project is focused on the geodynamic setting of Paleozoic granitic magmatism in the Western Carpathians as well as their correlation with analogous plutonic rocks across Variscan Europe, and updating the current petrogenetic models. The West-Carpathian Paleozoic granitic rocks represent a heterogeneous suite, which includes Early Paleozoic pre-Variscan (Cambrian-Ordovician), Variscan (Early Carboniferous), and post-Variscan (Permian) igneous lithotypes. The oldest group is related to an active Gonwana margin, and this transformed to Variscan orthogneisses. Relatively older Variscan granitoid plutons (ca. 365-350 Ma) may have formed in an extensional arc-type setting above an early Variscan (Lower Devonian) subduction zone. The following post-collision extension generated a younger group of the Variscan granites to tonalites (ca. 350-340, less 330 Ma). Both groups are consistent with the two anatectic events so far recognized at ca. 370-360 Ma and 350-340 Ma, respectively. Only minor part is formed in a post-collisional-extensional tectonic regime consistent with breakup of the Pangea supercontinent (mainly A- and specialized S-types, at ca. 280-250 Ma). Granitic rocks will be preferably studied by using the standard magmatic and metamorphic petrology methods namely: mineralogy, geochemistry |
COTAZ - Comparative taphonomy of micro- and macroinvertebrates: tracing the intensity of the taphonomically-active zone through time
Porovnávacia tafonómia mikro- and makrobezstavovcov: stopovanie intenzity tafonomicky-aktívnej zóny v čase

| Annotation: | The stratigraphic record is a unique archive of the dynamics of past ecosystems and their recovery in the wake of perturbations in the carbon cycle that led to abrupt warming, anoxia and acidification. The transformation of a sediment depth to a chronological axis (time), necessary in any reconstruction of ecosystem changes on the basis of the fossil record, is complicated owing to temporally-variable sedimentation, mixing and preservation and owing to difficulties in estimating time averaging of fossil assemblages. However, the intensity of taphonomic pathways is affected by ecosystem functioning (that determine sediment mixing and decomposition of organics), and the resulting taphofacies (assemblages of shells characterized by distinct preservation) can thus be informative about time averaging. Ecosystem perturbations can lead to a decline in bioturbation, which decreases time averaging and reduces the depth of the taphonomically-active zone (TAZ). We hypothesize that the taphonomic pathways prior to the diversification of predators and burrowers (Mesozoic Marine Revolution) were less intense and did not penetrate deep into sediments relative to faster disintegration in Cenozoic sediments with deeper mixing. These pathways also triggered a shallow depth of cementation, leading to the formation of the limestone-marl alternation (LMA). Here, we will (1) develop durability models of preservation on the basis of Holocene data, (2) assess the efficiency of taphonomic clock to estimate time averaging on the basis of skeletal preservation, (3) evaluate the pathways that affect the preservation of calcareous plankton, its contribution to the carbonate content during the Jurassic, and their role in the origin of LMA, and (4) trace changes in the intensity of the TAZ by comparing preservation of Jurassic and Cenozoic assemblages, comparing taphofacies of micro- and macroinvertebrates and trace fossils, separately in environments with and without oxygen depletion. |

| Project leader: | RNDr. Kotulová Júlia PhD. |
| Annotation: | The project is focused on the research of subsidence history, mainly in the Danube and East Slovakian Neogene basins. Due to a plentiful newly published research results, a need to revise older models is now present. With regards to the the aims of this work, new biostratigraphic, radiometric and geochemical analyzes (organic carbon content, Rock-Eval pyrolysis, vitrinite reflectance, biomarkers) will be performed. They will be derived from key deep wells, outcrops and correlated by using available reflection seismic. The analysis of subsidence history will allow the determination of the total, tectonic and thermal history in connection with the geodynamic development of the Western Carpathians. The study will also bring new insights into the hydrocarbon and geothermal systems of the basins. The final refined tectono-thermal models will therefore be potentially applicable in various energy industry sectors. |

| Annotation: | The main source of radon in buildings is the subsoil. Radon concentration in the soil air is not constant and depends on several parameters. A proper understanding of the mechanisms of radon transport from soil to homes can help reduce the health risk of the population from radon exposure. Concentrations of 222Rn, 226Ra, 232Th, 40K in the soil will be monitored in order to gain new knowledge about their distribution in the soil and also contribute to a better understanding of radon exhalation from soil as a function of soils parameters. The research will also improve the sensitivity of 222Rn measurement methods. Models describing the entry of radon into buildings and radon behavior in residential areas will be improved and tested. Based on a year-long measurement of indoor 222Rn and knowledge of the subsoil, seasonal correction factors for the calculation of average annual indoor radon, depending on the geological aspects of the soils, will be proposed and adjusted. |
ZveTtr - Weathering of minerals of the tetraedrite group: mobility of elements, supergene products and their stability
Zvetrávanie minerálov tetraedritovej skupiny: mobilita prvkov, supergénne produkty a ich stabilita
| Duration: | 1. 7. 2023 - 30. 6. 2027 |
| Evidence number: | APVV-22-0041 |
| Program: | APVV |
| Project leader: | Mgr. Števko Martin PhD. |
| Annotation: | The proposed project deals with detailed mineralogical study of weathering of minerals of the tetrahedrite group from various localities in Western Carpathians as well as in Bulgaria and Namibia, which are representing different geological environments as well as diverse compositional types of tetrahedrites. This is a very actual topic not only in the context of mineralogy, but also geochemistry and environmental mineralogy. Detailed study of the chemical composition of the primary/unaltered minerals of the tetrahedrite group, identification and advanced crystal-chemical research of all supergene products of weathering and determination of geochemical behaviour and mobility of the toxic elements will be included in this project. Both the standard mineralogical methods such as field work and sampling, followed by scanning electron microscopy (SEM), electron microanalysis (EMPA), single crystal and powder X-ray diffraction analysis (SC-XRD and PXRD), spectroscopic methods such as infrared absorption (FTIR) and Raman spectroscopy, as well as solution and relaxation calorimetry will be used. Expected results of this project should contribute significantly to the current knowledge of processes, mobility of elements, mineralogy of the products and stability of the supergene phases formed during the weathering of minerals of the tetrahedrite group. We believe that we will be able to define in detail, which phases are predominantly formed and how toxic elements like Cu, Hg, As or Sb are acting during the supergene/weathering processes in different geological environments. We also expect to identify which supergene products are stable or metastable at various pH/Eh conditions. Thus, the results of the proposed project may have an valuable output not only for mineralogists and geochemists, but also applicable in practice, especially in environmental management and remediation of the former mining sites. |
