Geosystems and hydrogeosystems
Geosystems and hydrogeosystems include complex coupled processes, interacting at multiple spatial and temporal scales. Understanding the geosphere (or planetsphere), as well as the hydrosphere, cryosphere, atmosphere and biosphere as coupled systems requires both observational data and models. Supported by field or laboratory data, geosystem and hydrogeosystem models are conceptual, analog or mathematical representations of natural systems, providing critical insights into processes that are otherwise difficult to understand. This theme combines sessions on theoretical, observational or experimental research related to geosystems and hydrogeosystems, including dynamic earth systems, and coupled water-rock or groundwater-surface water and/or atmosphere systems.
Resources, energy and environment
Responsible development of natural resources (including groundwater, minerals and hydrocarbons) is a crucial societal issue that relies on the acquisition, processing, analysis and integration of highly diverse geoscience data, as well as on their critical review and use by many stakeholders. To be successful, geosciences must converge within multidisciplinary research frameworks to improve global knowledge on sustainable natural resources development and best practices to protect the environment. This theme aims to bring together sessions focussing on topics such as mapping and characterization of geological and hydrogeological systems, understanding resource formation from source to surface and fluid circulation, as well as environmental characterization.
Data science for geosciences
Big data, artificial intelligence (AI) and data assimilation are becoming commonly-heard catch phrases. Indeed, the recent huge increase in geoscience data from multiple sources cannot easily be managed using conventional techniques to extract useful information such as deep data relations. Recent technical and software processing developments have now allowed tackling these tasks with great success in several domains including Earth sciences. For example, the Integra Goldrush and Disrupt_Mining innovation competitions have proven the high potential of AI as a resource exploration and estimation tool. The scope of this theme covers various domains within the field of data sciences, including visualization, management, processing and utilization of various geoscientific databases.
Geosciences and society
The development of natural resources can lead to significant environmental impacts on geological and hydrogeological systems. Society now demands that such development be responsible and sustainable. Local or regional populations can also suffer impacts related to various natural or anthropogenic geological risks (earthquakes, landslides, volcanic eruptions, climate change, groundwater contamination, etc.). Geoscientists are at the forefront to support developers, governments and communities impacted by natural resources development and natural geological hazards. This theme aims to merge sessions that will discuss the role of geoscientists in our society, among others for explanation of geological phenomena, education, development of government policies, or social acceptability of geological resources development.
