The second AUGURY workshop took place in Valflaunès, France between the 14th and the 18th of February. The groups from Zurich, Sydney and Lyon, and Tobias Rolf from Oslo joined in the beautiful Château de Valflaunès for sessions of work. The goal was to assess the progress made by the different groups, and to share experience, technology and knowledge. It was also the possibility for us to work as smaller groups on issues and new collaborations.It was very fruitful and we made some steps in the modeling and on how to connect it with geologic data.

Tutorials on StagYY, GPlates and the data assimilation tool Marie Bocher developed recently were interesting times to enter the skin of people of different backgrounds. Martina Ulvrova presented the Python library she contribute to develop with Stéphane Labrosse and his team to analyze Stag outputs. Everyone pushed for more technology sharing. The presence of Dietmar Müller, Simon Williams and Andrew Meredith from EarthByte was very important to start bridging more closely the convection models and the plate tectonic reconstructions. Over the workshop, Paul Tackley identified some significant improvements that will be made to make a step forward in the modeling.

The workshop took place in a wonderful atmosphere, and the sun was there to allow the hike of the Pic Saint Loup on the free afternoon. Everyone is looking forward the next workshop, but a meeting of the groups is already schedule for next EGU meeting in Vienna.

AUGURY @AGU Fall meeting 2015

AGU-Image1-1024x433

 

 

Marie Bocher, Claire Mallard, Martina Ulvrova and Nicolas Coltice attended AGU 2015 fall meeting. A group from E.T.H. Zurich with Charitra Jain, Antoine Rozel and Paul Tackley, as well as a team from Sydney with Simon Williams presented works as well.

It was the occasion to present the latest results from the project: Marie Bocher presented a poster on Ensemble filter method that will enable us to perform data assimilation in 3D spherical geometry in the course of 2016; Claire Mallard showed her analysis of convection models to understand why plates have specific size distribution; Martina Ulvrova presented results on convection with a free surface and continents, and Nicolas Coltice presented a work on small scale convection and a work on predicting tectonics with convection models.

The conference was the occasion to share knowledge and experience with colleagues around the globe and show how our team progressed in the past two years.
