Earth Surface Dynamics Geneva
We study the production, transport and deposition of sediments from mountains to basins.
Sedimentary layers record the history of the Earth. They contain stratigraphic cycles and patterns that precisely reveal the succession of climatic and tectonic conditions that have occurred over millennia, thereby enhancing our ability to understand and predict the evolution of our planet.
Congratulations to Anna Rauch for completing her PhD!
Anna Rauch has successfully completed her PhD thesis entitled "Dealing with Uncertainty and Ambiguity in Geological Maps – with Focus on Bedrock Geology".
She analysed the complexity and the inevitable uncertain and ambiguous character of geological information in maps, and then she provided useful resources.
Anna and co-authors propose two approaches to face ambiguous or uncertain data in maps. The first is a new method to assess and communicate the general reliability of bedrock information. The second proposes an algorithm that helps understand and manage the ambiguous character of geometrical information (i.e. traces) stored in geological maps.
Louis Honegger completed his PhD
On May 2020, Louis Honegger successfully completed his PhD thesis entitled "Climate and tectonic controls on stratigraphy in the Early Eocene Pyrenean foreland basin: new constraints from stable isotopes of carbon and oxygen"
In his thesis he used carbon and oxygen isotopes in the Early Eocene Pyrenean foreland basin to discuss the climatic and tectonic control on stratigraphy.
In more detail, he explored:
1) the origin of multi-millennial (~400 k.y.) stratigraphic cycles in the Ainsa deep-marine basin
2) the climatic impact and preservation potential in continental environments of short-lived (~40 k.y.) climatic events known as hyperthermals
3) the impact of the rising Pyrenean topography during the Eocene on the long-term isotopic foreland basin record.

# Luca Malatesta visit
Yesterday we had a visit from Luca Malatesta (University of Lausanne).
Luca met with many of us in the group and we had a very productive day discussing science!
Also a big thanks to Luca for his talk (see pic below) on long-term deformation of subduction margins! Super interesting!
Thanks for visiting Luca! Come again soon!
# A very successful Swiss Geoscience Meeting in Fribourg
An incredibly successful set of presentations by everyone in the group at SGM 2019 in Fribourg! Well done everyone!
Great to see all the different research being carried out across Switzerland!
Also a special congratulations to Sabi Peris Cabre on winning the Best Masters Poster! Well deserved Sabi!
