There are a number of general trends that currently affect the teaching and learning environment for Earth Scientists, varying from a gradual shift in the way humanity is exploring and exploiting our planet, via changes in the labour market asking for a new type of professional, to the introduction of new styles of teaching such as blended learning and flipping the classroom. Abstracts covered under this keyword, in some way or another, respond to such trends and (may) result in enhanced teaching and learning, which includes best practices, innovative ideas and suggestions for future improvements in tertiary education. In addition, abstracts are also invited that focus on outreach to the general public and the utilisation of our geoheritage (i.e. university or museum collections) in teaching and/or scientific studies.

These keywords cover studies that are fundamental to the study of the solid Earth. Topics can include studies related to the Earth’s mantle; oceanic and continental crust; the formation and crystallisation of magmas; the chemical compositions of igneous, metamorphic and sedimentary rocks; studies of volcanoes and various types of volcanism. While mostly fundamental in nature, applied topics include pollution of the atmosphere, surface or subsurface waters, the formation of ore deposits, and environmental impacts of volcanism (both subaerial, submarine as subglacial).

Geodesy is a science dedicated to the measurement and the mapping of the Earth’s surface. As the Earth’s surface is shaped by the planet’s gravity field, the classical definition includes the Earth’s gravitational potential. However, observing the Earth’s shape, orientation, rotation as well as the gravity field, also provides insight into spatial and temporal patterns of geophysical processes. These processes include e.g. sea-level rise, the tides, changing ice masses and global water circulation and deformations of the solid Earth. Topics therefore span from measurement systems to the actual investigation of geophysical processes.

Geodynamics covers all aspects of geodynamic processes in the lithosphere, mantle, and core. This encompasses observations, imaging, theory, numerical modelling (simulations) and laboratory modelling (experiments). Possible topics include the dynamics of subduction, mid-ocean-ridge processes, vertical and horizontal plate movements driving mountain building and basin formation, lithosphere dynamics, mantle convection, and core dynamics.

Geomorphology is the study of land-surface features and the dynamic processes that shape them. At the heart of geomorphology is the understanding landform history and dynamics, and predicting future changes through a combination of field observations, physical experiments, and numerical modelling. Research focussed on processes that ‘build topography’ as a result of the interplay between the effects of tectonic forces and processes that modify the terrain, such as weathering, erosion through running water, waves, glacial ice, wind and gravitational forces. This also includes human influences on geomorphological processes and the societal application of geomorphological research.

Developments in instrumentation, technology, methods and data handling used in any field of the geosciences, aiming to advance instrumentation and data systems and to share experiences and approaches with other subject areas.

Monitoring, modelling and prediction are basic issues in hydrology and geohydrology. Research is focussed on quantitative and qualitative aspects of fresh and saline groundwater and surface water systems, their dynamics and their interrelationships with the surrounding geology and ecosystems. This includes interactions between hydrology and geomorphology (e.g., erosion, sedimentation, groundwater systems), the relationships between hydrology and soils or sedimentary reservoirs, as well as the interaction between the hydrosphere and the biosphere (e.g., ecohydrology, wetlands). This may also include research into the management and operation of water resources by societies in various parts of the world, reservoir engineering, civil engineering, soil sciences en environmental sciences.

Research pertaining to the International Ocean Discovery Program (IODP), an international marine research collaboration dedicated to advancing scientific understanding of the Earth through drilling, coring, and monitoring the subseafloor, and the International Continental Scientific Drilling Program (ICDP), a multinational program to further and fund geosciences in the field of Continental Scientific Drilling.
