7. Geothermal Energy, CO2 Sequestration and Shale Gas

Conveners: Lyesse Laloui, Larryn Diamond, Paul Bossart
Supporting Organizations: Swiss Geothermal Society,
Swiss Association of Energy Geoscientists (SASEG)

Description:

This symposium deals with research and exploration of the sub-surface geology for the energy sector, and focusses on 3 topics: geothermal energy, CO2 sequestration and shale gas. The goal is to share experience and knowledge gained from those geo-energy fields. Furthermore, it explores the potential scientific directions in order to tackle particular challenges, methods and tools that can secure future energy demands and provide environmental friendly development solutions.

Geothermal heat extracted from depth in excess of 400 meters is defined as deep geothermal energy. The heat is extracted by hot-dry-rock processes or by drilling into aquifers or tectonic faults.

Carbon sequestration describes long-term storage of carbon dioxide or other forms of carbon in geological formations. It is a method to slow down greenhouse gases, which are mainly released by burning fossil fuels. The symposium will address the state of the art activities with emphasis on the integrity of geological storage system, through subsurface formation characterization, CO2 storage capacity, reservoir stability, monitoring technology, implementation and risk management methodology and environmental impact of CO2 storage.

Shale gas is natural gas that is formed and trapped within shale formations that are characterized by a consistent amount of organic content. The very low porosity, permeability and pore size of the material and thus the high capillary forces developed, enhance the fluid and gas trapping. As a consequence the hydraulic fracturing (fracking) technique is applied to create extensive artificial fractures in the shale formation which enhance the rate of the gas extraction. The control of the propagation of the hydraulic fractures is of major concern to guarantee the safety of the overlaying aquifers: the developed micro-seismicity is often used to monitor the fractures’ extent. Horizontal drilling is often performed where the hydraulic fracturing technique is applied. The drilling of deep vertical and horizontal wells in shales comes along with issues concerning wellbore stability and sand production, together with problems related to wastewaters and gas leakages control. The chemical composition of the drilling and fracturing fluids and their interaction with the shale environment is also of major concern.

Presentations related to these 3 topics are kindly invited. This includes field exploration work, lab experiments and modelling studies at all scales, but also work dealing with legal aspects is welcomed.

8. Modeling in Geomorphology

Conveners: C. Graf, I. Gärtner-Roer, N. Kuhn, R. Delaloye, M. Keiler, C. Scapozza, J. Müller, C. Levy, F. Herman, S. Castelltort, B. Staub
Supporting Organizations: Swiss Geomorphological Society (SGS)

Description:

Geomorphologists study processes, forms, materials and evolution of landscapes at Earth’s surface, often in close cooperation with practitioners and decision makers as well as with scientists from related disciplines. Especially in the context of global change, geomorphologists develop and promote the understanding of natural processes in geosystems, as well as the relationships between societies and geomorphological processes.

This open session on modeling in geomorphology at the 13th Swiss Geoscience Meeting encourages contributions from all areas of basic and applied geomorphology, including studies of the past and present processes and, for example, the implications for natural hazards, the influence on shaping the present landscape or landforms, or the influence of global change and how that may influence the processes, natural hazards, and resources in the future. Based on this year’s meeting theme “Modeling the Earth”, contributions focusing on modeling geomorphological issues will be preferred.

The Swiss Geomorphological Society (SGS) invites people from science and practice to present their geomorphologic interests and results in oral or poster presentations. Especially young scientists are encouraged to take the opportunity of presenting their theses and fostering relationships with colleagues.

9. Quaternary environments: landscapes, climate, ecosystems, human activity during the past 2.6 million years

Conveners: Philippe Rentzel, Christine Pümpin
Supporting Organizations: Swiss Society for Quaternary Research (CH-QUAT)

Description:

During the Quaternary Period, the last 2.6 million years of Earth’s history, changes in environments and climate shaped human evolution. Large-scale features of atmospheric circulation patterns varied significantly due to the dramatic changes in global boundary conditions, which accompanied abrupt changes in climate.

Past variations in the geosphere, hydrosphere, biosphere and in climate were archived in Quaternary deposits and provide critical information for the interpretation of present and future environmental changes. Quaternary research focuses on understanding these changes in environmental conditions, and on assessing their impact on landscapes, ecosystems, and human societies.

Within this context, the session brings together scientists from diverse disciplines in Earth Science, Archaeology and Environmental Science. In addition to studies focusing on the reconstruction and impact of past environmental change, we also invite presentations focusing on human expansions and cultural development, and contributions to methodological improvements in climate proxy studies or in methods of age determination. Topics may include all aspects of Quaternary science and we strongly encourage students and young scientists to present the results of their ongoing research.

12. Temperature and density influenced flow and transport of groundwater and coupled hydraulic processes

Conveners: Peter Bayer, Peter Huggenberger, Gunter Siddiqi, Eric Zechner
Supporting Organizations: Swiss Hydrogeological Society SGH

Description:

Efficient utilization of the shallow and deep underground as resource and storage medium relies on modern techniques of exploration, investigation, monitoring, simulation and assessment in various types of geological media. In all relevant application areas such as low- and high enthalpy geothermics, deep underground and tunnel constructions, as well as CO2 storage, the dynamic behaviour of geofluids and groundwater plays a prominent role. Separate analysis of flow or transport conditions gives a first insight into the hydraulic regime, but full system analysis is often only possible by considering coupled processes such as hydro-thermal and hydro-mechanical effects. Additionally, often variable thermal conditions and/or solute concentrations induce density-driven processes. The session aims to provide an overview of the current and future research in the field, covering any temporal or spatial scale.

We invite contributions from the broad field of temperature and density influenced flow and transport of groundwater and coupled hydraulic processes. Both in research and in practice, the realistic characterization of subsurface flow and heat transport, observations related to induced or natural variations of the thermal regime and solute concentration, the seasonal and long-term development of thermal, hydrochemical and mechanical conditions in aquifers, and energy and mass transfer across aquifer boundaries are focal points. This covers the geological, hydraulic and thermal characterization of shallow and deep aquifers including sealing aquitards. Of similar interest are contributions on hydraulic/thermal/mechanical processes relevant for underground constructions of e.g. deep wells, tunnels, caverns, CO2 storage systems, and hydrothermal and engineered geothermal systems. We seek new insights into advances in experimental design, reports from new laboratory tests and field observations, as well as demonstration of sequential or coupled modelling concepts.

13. The International Year of Soils: open session on soil security

Conveners: Nikolaus J. Kuhn, Stéphane Burgos, Emmanuel Frossard, Frank Hagedorn, Elena Havlicek, Jens Leifeld, Pascal Walther, Andreas Papritz, Urs Steiger
Supporting Organizations: National Research Programme “Sustainable Use of Soil as a Resource” (NRP 68)
Swiss Soil Science Society

Description:

2015 has been designated as the International Year of Soils by the Food and Agriculture Organization of the United Nations. Soil is undoubtedly one of the most valuable resources for humans, providing food and energy, but also many further ecosystem services. Soil is also under threat, e.g. by erosion, loss of nutrients or pollution. Unlike atmosphere and water, soil is threatened not “just” by pollution that could be cleaned up rather quickly, but by destruction that cannot be reversed in a feasible time span. Such soil losses therefore resembles the extinction of plants and animals. Surprisingly, there are no international conventions or directions to protect soil specifically.

The aim of this session is to discuss new ways and measures on how the maintenance and improvement soils in all its functions can be secured.

Supporting Organizations:

Description:

Biogeochemical processes are the basis for biotic controls on the chemistry of the environment or geochemical controls on the structure and function of ecosystems. Biosphere-geosphere interactions are critical in mediating element cycles, and act on a spatial continuum from the molecular to the global scale and link Earth’s distant past with its present and future.

This symposium aims at providing a platform for all scientists working on aspects related to the wider field of biogeochemistry on any spatial or temporal scale. Important topics will include, but are not restricted to:

• Element cycling
– geosphere-hydrosphere-terrasphere-atmosphere interactions

• Global change
– greenhouse gas production & consumption
– proxy indicators
– alterations of biogeochemical processes

• Isotopes
– tracers of biogeochemical processes

• Modelling & budgeting

16. Phenology and seasonality

Conveners: Martine Rebetez, Christian Rixen, This Rutishauser
Supporting Organizations: Swiss Commission for Phenology and Seasonality

Description:

The timing of the seasons is important to many bio-geoscientific systems. Across disciplines, data sources and methodological approaches, phenology often is a dominant factor for understanding underlying processes.

In this session, we welcome all studies related to the timing of biotic and abiotic events, in particular contributions directly related to Switzerland and the Alpine region. We are looking for contributions that present seasonality changes based on recent plant and animal phenological observations, historical documentary sources, or seasonality measurements using climate data, remote sensing, flux measurements or modelling studies. We invite contributions from students and senior scientist likewise to foster a lively discussion.

A few invited speakers will give a short overview on their research topic. These presentations will then lead to the main part of presentations, where we invite in particular young scientist to present their thesis and discuss it with colleagues.

The session also includes the award ceremony of the 5th «Schweizer Wettbewerb für Phänologie und Saisonalität».

Conveners: Nils Oesterling, Adrian Wiget, Massimiliano Cannata, Michael Sinreich
Supporting Organizations: Swiss Geodetic Commission,
Swiss Geotechnical Commission,
Swiss Geophysical Commission,
Swiss Hydrogeological Society

Description:

Digital data acquisition and 3D visualisation of geospatial objects and processes are already standard and are still gaining increasingly importance in geosciences. For instance geodetic data capture in combination with digital geological mapping constitutes an important basis for various tasks in engineering geology, natural hazard prevention and other geoscientific fields. Moreover, 3D modelling, GIS handling and visualisation of such data gives a better understanding of the respective problem setting.

In this symposium papers related to geospatial applications in all geosciences (geodesy, geophysics, geology, hydrogeology, engineering geology, geomorphology, etc.) will be presented. The focus will be on the following topics:

  • Development and application of digital tools for data capture
  • Transformation from field data to digital datasets and time series
  • Digital geological mapping and geoscientific information systems
  • 3D modelling, analysis of temporal variations and visualisation of geospatial objects and processes

Methodological papers as well as thematic case studies will be discussed. Contributions related to the topic of the SGM of this year «Modelling the Earth», e.g. data models, modelling techniques, exchange of data and models, visualisation and analysis of models, etc. are especially welcome this year.
