EMRP1.2 EDI

Geophysical methods have great potential for the characterization of subsurface properties and to inform geological reservoirs, hydrological and biogeochemical studies. In these contexts, the classically used geophysical tools only provide indirect information about the characteristics and heterogeneities of subsurface rocks. Petrophysical relationships hence have to be developed to provide links between physical properties (e.g. electrical conductivity, seismic velocity or attenuation) and the intrinsic parameters of interest (e.g. fluid content, hydraulic properties, pressure conditions). With the increase of distributed monitoring technique, geophysical methods are also deployed to study associated processes (e.g. flow, transport, biogeochemical reactions). This reinforce the need to establish petrophysical models with multidisciplinary approaches and diverse theoretical frameworks. While each physical property has its own intrinsic dependence on pore-scale interfacial, geometrical, and biogeochemical properties or on external conditions such as pressure or temperature, each associated geophysical method also has its own specific investigation depth and spatial resolution. Such complexity poses great challenges in combining theoretical developments with laboratory validations and scaling laboratorial observations to field practices. This session consequently invites contributions from various communities to share their models, their experiments, or their field tests and data in order to discuss multidisciplinary ways to advance the petrophysical relationship development and to improve our knowledge of complex processes in the subsurface. In the meantime, a range of low-carbon energy technologies incorporates reservoirs in the subsurface, whether as an energy resource (e.g., diverse types of geothermal energy) or as a storage medium (e.g., hydrogen storage, radioactive waste storage or CO2 sequestration). This session expects state-of-the-art laboratory experiments, focus on georeservoirs studies through geomechanics, geochemistry, petrophysics and materials science. It also welcomes contributions dealing with the development of novel apparatuses, newly developed sensors, or new experimental procedures to simulate geo-reservoir conditions and investigate rock and fluid properties at representative depths.

EMRP1.3 EDI

Rock mass deformation and failure at different stress levels (from the brittle regime to the brittle-ductile transition) are controlled by damage processes occurring on different spatial scales, from grain (µm) to geological formation (km) scale. These lead to a progressive increase of micro- and meso-crack intensity in the rock matrix and to the growth of inherited macro-fractures at rock mass scale. Coalescence of these fractures forms large-scale structures such as brittle fault zones, rockslide shear zones, and excavation damage zones (EDZ) in open pit mining and underground construction. Diffuse or localized rock damage have a primary influence on rock properties (strength, elastic moduli, hydraulic and electric properties) and on their evolution across multiple temporal scales spanning from geological time to highly dynamic phenomena as earthquakes, volcanic eruptions, slopes and man-made rock structures. In subcritical stress conditions, damage accumulation results in brittle creep processes key to the long-term evolution of geophysical, geomorphological and geo-engineering systems.
Damage and progressive failure processes must be considered to understand the time-dependent hydro-mechanical behaviour of fault damage zones and principal slip zones, and their interplay (e.g. earthquakes vs aseismic creep), volcanic systems and slopes (e.g. slow rock slope deformation vs catastrophic rock slides), as well as the response of rock masses to stress perturbations induced by artificial excavations (tunnels, mines) and loading. At the same time, damage processes control the brittle behaviour of the upper crust and are strongly influenced by intrinsic rock properties (strength, fabric, porosity, anisotropy), geological structures and their inherited damage, as well as by the evolving pressure-temperature with increasing depth and by fluid pressure, transport properties and chemistry.
In this session we will bring together researchers from different communities interested in a better understanding of rock deformation and failure processes and consequence, as well as other related rock mechanics topics. We welcome innovative and novel contributions on experimental studies (both in the laboratory and in situ), continuum / micromechanical analytical and numerical modelling, and applications to fault zones, reservoirs, slope instability and landscape evolution, and engineering applications.

EMRP1.6

The upscaling of laboratory results to regional geophysical observations is a fundamental question and a current challenge in geosciences. Indeed, earthquakes are non-linear and multi-scale problems, whose dynamics depend strongly on the geometry and the physical properties of the fault and its surrounding medium. To reproduce realistic boundary conditions in the laboratory, fault mechanisms are often scaled down to examine the physical and mechanical characteristics of earthquakes. Small-scale experiments are a powerful tool to study friction and bring to light new insights into weakening or dynamic rupture processes. However, it is not evident how the observed mechanisms can be extrapolated to large-scale observations, and this is where numerical simulations can help to bridge the gap in scale. Laboratory experiments, numerical simulations, and geophysical observations are complementary and necessary to understand fault mechanisms across the different scales. In this session, we aim to convene contributions dealing with multiple aspects of earthquake mechanics, such as:
(i) the thermo-hydro-mechanical processes associated with all the different stages of the seismic cycle, e.g., healing, nucleation, co-seismic fault weakening;
(ii) multidisciplinary studies combining laboratory and numerical experimental results;
(iii) bridging the gap between the different scales of fault deformation mechanisms.

We particularly welcome novel observations and/or innovative approaches to study earthquake faulting. Contributions from early career scientists are highly solicited.

This session focuses on the investigation of deep geothermal reservoirs in any geological environment including sedimentary basins to crystalline basement rocks. The targets encompass hydrothermal, petrothermal, enhanced geothermal, and close loop systems. We particularly welcome contributions related to reservoir exploration, monitoring and operation in fractured and faulted reservoirs, including the assessment of their sustainable usage as well as of potential hazards such as induced seismicity. This session features multi-disciplinary and cross-scale studies characterizing the reservoir performance and behavior by additional experimental and numerical analysis of related THMC processes.

ERE5.2

Faults and fracture zones are fundamental features of geological reservoirs that control the physical properties of the rock. As such, understanding their role in in-situ fluid behaviour and fluid-rock interactions can generate considerable advantages during exploration and management of reservoirs and repositories.

Physical properties such as frictional strength, cohesion and permeability of the rock impact deformation processes, rock failure and fault/fracture (re-)activation. Faults and fractures create fluid pathways for fluid flow and allow for increased fluid-rock interaction.

The presence of fluids circulating within a fault or fracture network can expose the host rocks to significant alterations of the mechanical and transport properties. This in turn can either increase or decrease the transmissibility of a fracture network, which has implications on the viability and suitability of subsurface energy and storage projects. Thus, it is important to understand how fluid-rock interactions within faults and fractures may alter the physical properties of the system during the operation of such projects. This is of particular interest in the case of faults as the injection/ remobilisation of fluids may affect fault/fracture stability, and therefore increase the risk of induced seismicity and leakage.

Fieldwork observations, monitoring and laboratory measurements foster fundamental understanding of relevant properties, parameters and processes, which provide important inputs to numerical models (see session “Faults and fractures in geoenergy applications 1: Numerical modelling and simulation”) in order to simulate processes or upscale to the reservoir scale. A predictive knowledge of fault zone structures and transmissibility can have an enormous impact on the viability of geothermal, carbon capture, energy and waste storage projects.

We encourage researchers on applied or interdisciplinary energy studies associated with low carbon technologies to come forward for this session. We look forward to interdisciplinary studies which use a combination of methods to analyse rock deformation processes and the role of faults and fractures in subsurface energy systems, including but not restricted to outcrop studies, monitoring studies, subsurface data analysis and laboratory measurements. We are also interested in research across several different scales and addressing the knowledge gap between laboratory scale measurements and reservoir scale processes.

Geological media are a strategic resource for the forthcoming energy transition and constitute an important ally in the fight to mitigate the adverse effects of climate change. Several energy and environmental processes in the subsurface involve fluid circulation into geo-reservoirs, which activates a series of multi-physical interactions in the porous and fractured rock. Changes in pore pressure, stress and temperature, rock deformation and chemical reactions occur simultaneously and impact each other. Forecasts are bounded to the adequate understanding of field data associated with thermo-hydro-mechanical-chemical (THMC) processes and predictive capabilities heavily rely on the quality of the integration between the input data (laboratory and field evidence) and the mathematical models describing the evolution of the multi-physical systems. The relationship between the observations and the modelled changes is, however, often ubiquitous, which challenges the interpretation of the observations in regard of the physical processes in play within the reservoir. Certain geological settings involve an additional complexity, especially when clay materials are present, which have a versatile role acting as both assets and challenges in energy extraction.
This session is dedicated to studies investigating all or part of these THMC interactions by means of experimental, analytical, numerical, multi-scale, data-driven and artificial intelligence methods. Studies focusing on laboratory characterization and on monitoring and interpreting in-situ geological and geophysical evidence to validate or calibrate the multi-physical behavior of rocks and clays are also welcome. Applications in carbon capture and storage (CCS), radioactive waste storage, gas storage, energy storage, mining, geothermal systems, reservoir monitoring and management and geotechnical applications would be relevant.

Geological storage of energy and carbon dioxide is of great importance in the pathways of carbon neutrality. There is a dramatic increase in interest in studying the multi-physical processes in geo-storage using pore-scale and molecular-scale approaches. The microscopic understanding of flow in porous media, poromechanics, microfracture evolution, and fluid-structure interaction is essential in improving the description and prediction at the continuum-scale. We invite contributions focused on addressing multi-physical processes through pore-scale and molecular-scale approaches for all aspects in relation to carbon sequestration, hydrogen storage, and compressed air storage.
Relevant topics include but are not limited to:
• Simulation of multi-physical processes by pore-scale and molecular-scale methods (molecular simulation, lattice Boltzmann method, pore network model, smooth particle hydrodynamics, and phase-field simulation)
• Advanced experimental approaches for new physical insights (microfluidics, nanofluidics, and nano-indentation)
• Upscaling methods from molecular-scale and pore-scale to continuum-scale

Geological resources are playing a key role in the endeavor of reaching net-zero greenhouse gases emissions. Geo-energy projects, such as geothermal energy, geologic carbon storage and subsurface energy storage, are rapidly growing in number with a tendency that is expected to accelerate. This massive use of the subsurface entails coupled processes which, in some cases, may cause a counterintuitive response of the geological media, such as reverse-water level fluctuations, high-magnitude post-injection induced seismicity and non-uniform ground deformation patterns. To successfully deploy geo-energy applications, we should improve our understanding and forecasting capability of the induced coupled processes.
In this session, we welcome contributions on experimental and numerical studies that tackle with cross-cutting subsurface energy challenges; multiscale investigations of geo-energy applications, such as CO2 sequestration, enhanced geothermal systems, nuclear waste disposal and subsurface energy storage; advances in the state-of-the-art in the understanding of the coupled thermo-hydro-mechanical-chemical (THMC) processes induced by these geo-energy applications; developments in ground deformation measurements using geomatic applications; characterization, prediction and understanding of triggering mechanisms of induced seismicity; experimental activities in dedicated subsurface field facilities that allow for focused in situ studies under controlled conditions at well-characterized locations.

Mountain regions are a complex system of different glacial, paraglacial and periglacial environments rapidly changing due to global warming. In this context, short-term landscape evolution is affected by glacier motion, by a variety of mass movements including slow rock slope deformations, rock and debris slides, rockfalls, as well as by periglacial features such as rock glaciers. These mass movements are driven be different processes, evolve at different rates and can pose different risks to lives, human activities and infrastructure. The physics of rock slope degradation and the dynamics of failure and transport define the hazards.

In this session we bring together researchers from different communities interested in a better understanding of the physical processes controlling mass movements mass around the world in glacial, paraglacial and periglacial environments, and investigating their evolution in a changing climate. Topics range from state-of-the-art methods for assessing, quantifying, predicting, and protecting against alpine slope hazards across spatial and temporal scales to innovative contributions dealing with mass movement predisposition, detachment, transport, and deposition. The selected contributions are expected to: (i) provide insights from field observations and/or laboratory experiments; (ii) apply statistical methods and/or artificial intelligence to identify and map mass movements; (iii) present new monitoring approaches (in-situ and remote sensing) applied at different spatial and temporal scales; (iv) use models (from conceptual frameworks to theoretical and/or advanced numerical approaches) for the analysis and interpretation of the governing physical processes; (v) develop strategies applicable for hazard assessment and mitigation. We also aim at triggering discussions on effective countermeasures that can be implemented to increase preparedness and risk reduction, and studies that integrate social, structural, or natural protection measures.

The session strives to build a community and to grow networks at EGU and beyond.

From the real-time integration of multi-parametric observations is expected the major contribution to the development of operational t-DASH systems suitable for supporting decision makers with continuously updated seismic hazard scenarios. A very preliminary step in this direction is the identification of those parameters (seismological, chemical, physical, biological, etc.) whose space-time dynamics and/or anomalous variability can be, to some extent, associated with the complex process of preparation of major earthquakes.
This session wants then to encourage studies devoted to demonstrate the added value of the introduction of specific, observations and/or data analysis methods within the t-DASH and StEF perspectives. Therefore, studies based on long-term data analyses, including different conditions of seismic activity, are particularly encouraged. Similarly welcome will be the presentation of infrastructures devoted to maintain and further develop our present observational capabilities of earthquake related phenomena also contributing in this way to build a global multi-parametric Earthquakes Observing System (EQuOS) to complement the existing GEOSS initiative.
To this aim this session is not addressed just to seismology and natural hazards scientists but also to geologist, atmospheric sciences and electromagnetism researchers, whose collaboration is particular important for fully understand mechanisms of earthquake preparation and their possible relation with other measurable quantities. For this reason, all contributions devoted to the description of genetic models of earthquake’s precursory phenomena are equally welcome.

Tectonic faults accommodate plate motion through various styles of seismic and aseismic slip spanning a wide range of spatiotemporal scales. Understanding the mechanics and interplay between seismic rupture and aseismic slip is central to seismotectonics as it determines the seismic potential of faults. In particular, unraveling the underlying physics controlling these deformation styles bears a great deal in earthquake hazard mitigation, especially in highly urbanized regions. We invite contributions from observational, experimental, geological, and theoretical studies that explore the diversity and interplay among seismic and aseismic slip phenomena in various tectonic settings, including the following questions: (1) How does the nature of creeping faults change with the style of faulting, fluids, loading rate, and other factors? (2) Are different slip behaviors well separated in space, or can the same fault areas experience different failure modes? (3) Is there a systematic spatial or temporal relation between different types of slip?

Many regions of the Earth, from crust to core, exhibit anisotropic fabrics which can reveal much about geodynamic processes in the subsurface. These fabrics can exist at a variety of scales, from crystallographic orientations to regional structure alignments. In the past few decades, a tremendous body of multidisciplinary research has been dedicated to characterizing anisotropy in the solid Earth and understanding its geodynamical implications. This has included work in fields such as: (1) geophysics, to make in situ observations and construct models of anisotropic properties at a range of depths; (2) mineral physics, to explain the cause of some of these observations; and (3) numerical modelling, to relate the inferred fabrics to regional stress and flow regimes and, thus, geodynamic processes in the Earth. The study of anisotropy in the Solid Earth encompasses topics so diverse that it often appears fragmented according to regions of interest, e.g., the upper or lower crust, oceanic lithosphere, continental lithosphere, cratons, subduction zones, D'', or the inner core. The aim of this session is to bring together scientists working on different aspects of anisotropy to provide a comprehensive overview of the field. We encourage contributions from all disciplines of the earth sciences (including mineral physics, seismology, magnetotellurics, geodynamic modelling) focused on anisotropy at all scales and depths within the Earth.

In this session we want to celebrate the scientific achievements of W. Jason Morgan, the discoverer of Plate Tectonics and Mantle Plumes, while looking into the future developments of the scientific revolution that he helped to ignite. Fifty years after their discovery, we still have basic questions in our understanding of how Plate Tectonics and Mantle Plumes are linked to the flow structure of the mantle, heat loss from Earth's core, and Earth's evolution from its accretion to the present day. Inspired by these concepts, the modern subdisciplines of Tectonics, Geodynamics, Seismology, Geochemistry, and Earth Magnetism/Rock Physics continue to grapple with gaining a deeper understanding of our planet. Here we welcome contributions that highlight recent progress and problems in this endeavor.

We welcome contributions to our session dedicated to advancements in electromagnetic (EM) geophysics. EM geophysics applications span from the Earth's surface to its deep mantle. This session highlights innovations in instrumentation, data acquisition, algorithm development, and EM applications in both terrestrial and marine environments, as well as airborne and satellite missions. Discussions will encompass natural and controlled EM sources, geomagnetically induced currents, space weather, and geomagnetic field studies based on observatory data. The significance of EM in global induction, tectonics, magmatic and volcanic systems, and its utility in identifying hydrocarbon, geothermal, mineral resources, and storage is increasingly recognized. Examining near-surface structures with EM geophysics is crucial for environmental, urban, and hydrological studies. Additionally, the session will integrate disciplines other than EM geophysics, better utilizing EM results through additional information from other geophysical methods, rock physics, geochemistry, and geology to reveal complex subsurface structures and their evolving dynamics over time.

Earth’s cryosphere demonstrates itself in many shapes and forms, but we use similar geophysical and in-situ methods to study its wide spectrum: from ice-sheets and glaciers, to firn and snow, sea ice, permafrost, and en-glacial and subglacial environments.

In this session, we welcome contributions related to all methods in cryospheric measurements, including: advances in radioglaciology, active and passive seismology, geoelectrics, acoustic sounding, fibre-optic sensing, GNSS reflectometry, signal attenuation, and time delay techniques, cosmic ray neutron sensing, ROV and drone applications, and electromagnetic methods. Contributions can include field applications, new approaches in geophysical or in-situ survey techniques, or theoretical advances in data analysis processing or inversion. Case studies from all parts of the cryosphere, including snow and firn, alpine glaciers, ice sheets, glacial and periglacial environments, alpine and arctic permafrost as well as rock glaciers, or sea ice, are highly welcome.

This session will give you an opportunity to step out of your research focus of a single cryosphere type and to share experiences in the application, processing, analysis, and interpretation of different geophysical and in-situ techniques in these highly complex environments. This session has been running for over a decade and always produces lively and informative discussion. We have a successful history of PICO and other short-style presentations - submit here if you want a guaranteed short oral!

Geo-electromagnetic methods encompass a diverse range, including natural source magnetotelluric, time-domain, and frequency-domain controlled source EM, as well as DC resistivity and Induced Polarization. Their unique sensitivities to the Earth's electric properties span scales from mere meters near the surface to depths reaching tens or even hundreds of kilometers. These methods effectively characterize the subsurface, revealing information on fluid distribution, mineral presence, tectonic activities, and even man-made structures.

While geo-electromagnetic methods have long been pivotal in resource exploration, the emerging challenges of our time—ranging from energy transitions and climate change to urban resilience—open new avenues for applied geo-electromagnetic research. The ability of geo-electromagnetic methods to detect specific geological units and processes proves crucial in understanding and addressing these contemporary challenges.

This session is envisioned as an annual showcase for the geo-electromagnetic community, highlighting advancements and discoveries in the field. We warmly invite insightful contributions from all areas of geo-electromagnetic research, encompassing methodological innovations, observational discoveries, theoretical perspectives, and case studies. Specifically, we especially welcome submissions that spotlight innovative applications of EM, whether through cutting-edge instrumentation, unique settings, or areas of strategic significance.

GD8.1 EDI | PICO

Understanding the structures and dynamics of the core of a planet is essential to constructing a global geochemical and geodynamical model, and has implication on the planet's thermal, compositional and orbital evolution.

Remote sensing of planetary interiors from space and ground based observations is entering a new era with perspectives in constraining their core structures and dynamics. Meanwhile, increasingly accurate seismic data provide unprecedented images of the Earth's deep interior. Unraveling planetary cores' structures and dynamics requires a synergy between many fields of expertise, such as mineral physics, geochemistry, seismology, fluid mechanics or geomagnetism.

This session welcomes contributions from all the aforementioned disciplines following theoretical, numerical, observational or experimental approaches.

Mantle circulation simulations are now capable of a high level of precision and complexity that allows the creation of numerous "Earth-like" models. Likewise, advances in observation resources and methods have improved the quantity and quality of data on the Earth's interior. Combining these developments presents a unique opportunity to enhance our understanding of mantle dynamics and evolution over geological time scales. However, the exact physics leading to Earth-like simulations remains debated (e.g. the existence of a primordial layer, the core-mantle-boundary temperature, etc...). Furthermore, constraining geodynamical simulations or assessing their predictions with observational data can be challenging, for example, due to data noise, issues related to inverse methods, or uncertainty propagation.

This session aims to explore how observational data can be used to constrain or assess geodynamical simulations and advance our knowledge of the physical processes that govern the Earth's mantle. We invite submissions from various fields, including seismology, geochemistry, mineral physics or geomagnetism where observations have the potential to constrain geodynamical simulations or assess their predictions. The nature of these studies can be purely observational, exploring the inversion of data to possible Earth models or proposing metrics to assess how Earth-like a model is.

This session also aims to compare these observations and address their potential to constrain or assess geodynamical simulations, with the ultimate goal of better understanding which parameters may cause models to be more or less Earth-like.

ST4.9 EDI

Over the last 20 years, numerous spacecraft have been launched into near-Earth space. In particular, the Low Earth Orbit (LEO) is becoming an increasingly popular destination for new missions. There are many advantages of utilizing the LEO orbit, such as the relatively low launch costs, close proximity to the Earth – crucial for studying the atmosphere-ionosphere system, as well as for geomagnetic field observations – and a more rapid turnover of spacecraft which allows to keep up with state-of-the-art technology. The LEO orbit is now home to over 3000 satellites, and the total number of spacecraft is set to substantially increase in the following years. The LEO missions have provided enormous volumes of data, and offer unprecedented opportunities for transforming our knowledge of various regions and processes within the geospace.

This session focuses on the analysis and interpretation of new data sets collected by LEO satellites, including CubeSats, and their possible use for modeling and applications related to Space Weather. We invite contributions that analyze the ionosphere-thermosphere-magnetosphere system, effects of particle precipitation, and geomagnetic field measurements, among other topics. Studies using both in-situ and remote sensing observations are encouraged. This session is also open to exploring novel data sets that were previously inaccessible, including commercial data recently released to the public, as well as data sets where scientific applications arose as unintended by-products of other analyses. Studies involving multi-spacecraft analysis are particularly encouraged. Additionally, submissions related to concept and Observations System Simulation Experiment (OSSE) studies for new and planned missions are welcome.

Time series are a very common type of data sets generated by observational and modeling efforts across all fields of Earth, environmental and space sciences. The characteristics of such time series may however vastly differ from one another between different applications – short vs. long, linear vs. nonlinear, univariate vs. multivariate, single- vs. multi-scale, etc., equally calling for specifically tailored methodologies as well as generalist approaches. Similarly, also the specific task of time series analysis may span a vast body of problems, including
- dimensionality/complexity reduction and identification of statistically and/or dynamically meaningful modes of (co-)variability,
- statistical and/or dynamical modeling of time series using stochastic or deterministic time series models or empirical components derived from the data,
- characterization of variability patterns in time and/or frequency domain,
- quantification various aspects of time series complexity and predictability,
- identification and quantification of different flavors of statistical interdependencies within and between time series, and
- discrimination between mere correlation and true causality among two or more time series.
According to this broad range of potential analysis goals, there exists a continuously expanding plethora of time series analysis concepts, many of which are only known to domain experts and have hardly found applications beyond narrow fields despite being potentially relevant for others, too.

Given the broad relevance and rather heterogeneous application of time series analysis methods across disciplines, this session shall serve as a knowledge incubator fostering cross-disciplinary knowledge transfer and corresponding cross-fertilization among the different disciplines gathering at the EGU General Assembly. We equally solicit contributions on methodological developments and theoretical studies of different methodologies as well as applications and case studies highlighting the potentials as well as limitations of different techniques across all fields of Earth, environmental and space sciences and beyond.

EMRP3 – Paleomagnetism and Environmental Magnetism

Sub-Programme Group Scientific Officer: Eric Font

EMRP3.2 EDI

The recent methodological and instrumental advances in paleomagnetism and magnetic fabric research further increased their already high potential in solving geological, geophysical, and tectonic problems. Integrated paleomagnetic and magnetic fabric studies, together with structural geology and petrology, are very efficient tools in increasing our knowledge about sedimentological, tectonic or volcanic processes, both on regional and global scales. This session is intended to give an opportunity to present innovative theoretical or methodological works and their direct applications in various geological settings. Especially welcome are contributions combining paleomagnetic and magnetic fabric data, showing novel approaches in data evaluation and modelling to reconstruct and analyze paleogeography on the regional to global scale across all timescales.

To retrieve the variation of the Earth’s magnetic field in the past, in scales varying from hundreds to millions of years, indirect records from archaeological material, volcanic rocks, sediments, and speleothems are necessary. Such data can be used for geomagnetic field reconstructions and field modeling, contributing to a better understanding not only of the field changes at the Earth’s surface but also at the core-mantle boundary, offering indirect evidence of the processes that take place in the Earth’s core. This session welcomes abstracts presenting new directional and palaeointensity data from short- (secular variation) to long- (magnetic reversals) time scales, methodological advances, and archaeo/palaeomagnetic reconstructions at regional and global scales. Particular attention is focused on the investigation of the South Atlantic Anomaly (SAA) and other regions of weak intensity field, exploring the interactions of the SAA with the biosphere and forecasting its possible connection with climate and the corresponding radiation effects on the upcoming Low-Earth Orbit (LEO) satellite missions. Applications in the fields of geomagnetism, stratigraphy, volcanology, absolute and relative chronology, climate, geobiology, and geospace are welcome.
