Title:

Structural Geology and Tectonics. (Open Session)

Conveners: Neil Mancktelow, Stefan Schmid
Supporting Organizations: Swiss Tectonics Studies Group, Swiss Geological Society

Description:

Presentations are invited covering the whole range of structural geology and tectonics, including field, experimental and model studies of structures from the micro-scale to the scale of mountain belts. Young researchers are particularly encouraged to participate and present their results.


Title:

Mineralogy-petrology-geochemistry. (Open Session)

Conveners: Othmar Müntener
Supporting Organizations: Swiss Society of Mineralogy and Petrology (SSMP)

Description:

This session is open to all scientists working in the broad field of mineralogy, petrology and geochemistry. We especially invite young researchers to present their results from doctoral or post-doctoral research project and intend to create a platform for exchanging ideas between young and experienced researchers.


Title:

Quaternary climate change. (Open Session)

Conveners: Frank Preusser
Supporting Organizations: Schweizerische Kommission für Quartärforschung (SKQ)

Description:

The Quaternary period is mainly characterised by repeated and abrupt changes in climatic conditions. Most of Quaternary research is hence related to deciphering the climate evolution of the past and its impact on environmental conditions and processes with special regard to the evolution of early man. This session invites contributions related to this general topic from all kind of disciplines. Beside studies focusing on the reconstruction and impact of past climate change on environmental conditions and human response, contributions to methodological improvements such as climate proxy or methods of age determination are also welcome.


Title:

Meteorology and climatology (Open Session)

Conveners: Rolf Philipona, Markus Furger
Supporting Organizations: Swiss Meteorological Society

Description:

Presentations are invited covering the whole range of actual research in meteorology and climatology in the regional and global scale, including phenomenological and experimental aspects in different fields, surface and satellite measurements, remote sensing as well as model studies. Young researchers are particularly invited to present their research and results. Contributions are welcome in German, French or English.


Title:

Open Cryosphere session

Conveners: M. Hoelzle, A. Bauder, B. Krummenacher, C. Lambiel, M. Lüthi, M. Phillips, J. Schweizer, M. Schwikowski
Supporting Organizations: Swiss Snow, Ice and Permafrost Society

Description:

This session addresses all topics, which are related to the Alpine and Polar Cryosphere. We expect contributions covering the whole range of Alpine and Polar snow, ice and permafrost research. We encourage theoretical, experimental as well as practical contributions, especially from young researchers. Presentations that address the aspects of dynamics and thermodynamics of snow, ice and permafrost and impacts related to natural hazards are particularly welcomed.


Title:

Floods of August 2005 - new scientific insights

Conveners: Chirstoph Hegg, Gian Reto Bezzola, Dieter Rickenmann, Manfred Stähli
Supporting Organizations: Swiss Geomorphological Society, Kommission Hydrologie (CHy), Schweizerische Gesellschaft für Hydrologie und Limnologie (SGHL)

Description:

The flood of August 2005 was the most costly natural disaster in Switzerland in the last decades. Such events are a extraordinary occasion to learn more about them with the goal of being better prepared in the future. This is the intention of the project "Ereignisanalyse Hochwasser 2005" lead by BAFU and WSL. Many but not all scientists working in the field of natural hazards are involved in this study. It is the goal of this session to give to all scientists to present their insights into this event and the consequences they draw from their findings to the scientific community. With this the convenors want to ensure that all relevant knowledge is incorporated into the project "Ereignisanalyse Hochwasser 2005".


Title:

Fossils, palaeoenvironments and evolution - the Swiss contribution

Conveners: Peter O. Baumgartner, Damien Becker, Danielle Decrouez
Supporting Organizations: Swiss Palaeontologic Society, KSPA

Description:

This symposium will have 2-4 invited keynote speakers, who will present state-of-the-art overview talks on either fossil groups or research topics related to fossils. We expect the keynote speakers to show to the geoscience community how palaeontology contributes fundamentally to the modern earth- and environemntal sciences.

In addition, this symposium is an open session to all paleontologists, but also to geochemists and biogeoscientists who want to present research on fossil (and recent) biota.


Title:

Physics of magmatic and volcanic processes: understanding the fate of magmas from the mantle to the stratosphere

Conveners: Catherine Annen, Costanza Bonadonna
Supporting Organizations:

Description:

The objective of this symposium is to gather geoscientists who use numerical modelling and laboratory experiments to explore magmatic and volcanic processes. We call for contributions in the fields of magmatic and eruptive physics and dynamics. From their generation to their final emplacement, either as plutons in the crust or as volcanic deposits on the Earth's surface, magmas experience a series of physical processes that include differentiation, mixing, segregation, extraction, transport, fragmentation, intrusion, eruption and deposition. Numerical modelling allows to quantifying these processes and estimate over which scales (spatial and temporal) they occur. Numerical and analog experiments are powerful tools to test and constrain qualitative models and theoretical representations and provide understanding of the physics underlying complex natural phenomena.


Title:

Geohazards in lakes

Conveners: Flavio S. Anselmetti, Daniel Ariztegui
Supporting Organizations: Commission for Oceanography and Limnology (COL)

Description:

Water, shorelines and subsurface of lakes are exposed to a variety of processs that often impose a series of geohazards. For this session, we invite contributions that investigate lakes and their links to natural and anthropogenically-induced hazards. Contributions might include environmental pollution studies, volcanic hazards in and around lakes, subaerial and subaquatic mass movements, biological changes and effects of water level changes and floods. The session will comprise six invited keynote speakers and posters. Studies of variable temporal and spatial scales are welcome, including reconstructions of past catastrophic events, ongoing processes, but also modelling studies and predictions of future threats.

Invited lectures and themes:
- Volcanic hazards: CO2 and Methane degassing in lakes.
- Assessment of hazards related to the formation of glacier dammed lakes.
- Modelling the impact of climate change in lakes and reservoirs.
- Rock falls an their impact in lake sedimentation.
- Flooding and lake level changes
- Water and sediment pollution in artificail reservoirs.


Title:

Social Perception of Natural Catastrophes and Forces of Nature

Conveners: Doris Wastl-Walter, Patricia Felber
Supporting Organizations:

Description:

In mountain areas as well as in the flat land, forces of nature create smaller and bigger catastrophes: avalanches and mood flows kill people and destroy houses, floodings paralyze whole cities and ruin produce, severe wind storms root out hectares of forest. Humans have always lived with the risks and dangers of the forces of nature, challenged it and fought it. Thus, whitin the last decade humans seemed to loose more often against nature’s force. We are presenting how persons concered are perceiving and dealing with the potential risks of losing their house, beloved landscape, income, or even their lives. Our findings are relevant for spatial and landscape planning in high risk areas and for minimizing further catastrophes.


Title:

Terrestrial biogeochemical cycles (and global change)

Conveners: M.W.I. Schmidt, F. Hagedorn
Supporting Organizations:

Description:

Research of terrestrial biogeochemical cycles aims to develop an understanding of the earth system with all its ecological implications. Processes on landscape, ecosystem and global levels are closely interrelated and mutually influence each other.

This symposium focuses on:
- biogeochemical cycles in terrestrial systems, including soil, vegetation and atmosphere
- how ecosystems and biogeochemical cycles interact with changes in climate, land use and diversity,
- experiments to reveal functional relationships,
- paleoclimatological and paleoecological methods, to draw conclusions about the adaptability of organisms in the past and future
- the application of a whole spectrum of techniques, including, inorganic-chemical, biochemical, microscopic and mineralogical analysis, and the use of isotopes
