TIMEleSS Annual Meeting

TIMEleSS Annual Meeting 2020The 2020 TIMEleSS Annual Meeting was held online on 8-9 September 2020. Members from the Université de Lille (Julien Chantel, Jeffrey Gay, Estelle Ledoux, Sébastien Merkel), the Westfälische Wilhelms-Universität, Münster (Matthias Krug, Federica Rochira, Morvarid Saki, Angelo Pisconti, Christine Thomas), and the Deutsche GeoForschungsZentrum, Potsdam (Sergio Speziale) met for two half-days to discuss current advances and future plans.

The first day was dedicated to progress report by the PhD students. The second day followed by a scientific presentation by our guest Morvarid Saki and discussions on the geophysical implications of the results.

Despite the 2020 conditions, the TIMEleSS project is nicely moving forward. Students are reaching a stage when they fully interact with each other. The PIs can’t wait for next year with results and publications!

 

Seismology training for TIMEleSS members!

TIMEleSS February 2020 seismology trainingTIMEleSS members are in Münster!

TIMEleSS PI C. Thomas is hosting a seismology training for TIMEleSS students.

Participants include TIMEleSS students E. Ledoux, J. Gay, F. Rochira, M. Krug, and guests from WWU Münster Mineralogy and Seismology labs.

The training is the opportunity to move on to the next step in the TIMEleSS project: combining Mineral Physics and Seismology observations and try to say something about deep mantle processes!

TIMEleSS Training on Polycrystal Properties Modeling

Training on Polycrystal Properties Modeling, Oct 2019

This weeks, students from the TIMEleSS project and our special guests are in Lille to learn about polycrystalline properties.

The course is focused on calculating elastic properties and seismic wave propagation features in a polycrystal, textured or not. We also spend some time trying to model texture development in a deformed polycrystalline aggregate thanks to VPSC simulations.

The participants from the TIMEleSS project, Jeffrey Gay (Lille), Estelle Ledoux (Lille), Matthias Krug (Münster), Federica Rochira (Münster), are delighted to host our very special guests, Tommaso Mandolini (Lille), Ilya Kupenko (Münster), Angelo Pisconti (Münster), Morvarid Saki (Münster), and Lea Pennacchioni (GFZ) for the week.

All should dream of Euler angles and 3D-rotations by the end of the week!

TIMEleSS Annual Meeting

TIMEleSS Annual Meeting, Aachen, Germany, July 2019

The TIMEleSS Annual Meeting was held at the Jugendherberge in Aachen, Germany, on 23-24 July 2019. Members from the Université de Lille (Julien Chantel, Jeffrey Gay, Estelle Ledoux, Sébastien Merkel), the Westfälische Wilhelms-Universität, Münster (Matthias Krug, Federica Rochira, Morvarid Saki, Christine Thomas), and the Deutsche GeoForschungsZentrum, Potsdam (Sergio Speziale) met for two days to discuss current advances and future plans.

The first day was dedicated to progress report by the PhD students followed by a scientific presentation by our guest Morvarid Saki. Projects members discussed potential interactions and plans for the next year during the second day.

The meeting a was great opportunity to highlight the current achievements of the project and to focus the work that remains. We now have lot’s of projects and results to look forward to. See you next year for the next meeting and further results!

Datatron for the TIMEleSS project

TIMEleSS May 2019 datatron

The synchrotron guys of the TIMEleSS project met up for a datatron the second week of May 2019. During a TIMEleSS datatron, we all sit in a room and get moving on data processing from our recent synchrotron experiments!

The datatron was attented by M. Krug, E. Ledoux, and J. Gay, PhD students involved in the TIMEleSS project, S. Merkel, the PI for TIMEleSS. We also welcomed 3 guests during this week: J. Wright, from ID11 at ESRF, A. Dewaële from CEA, and M. Bykov from the Bayerisches Geoinstitut.

The next TIMEleSS datatron has not been planned yet but may happen later in 2019.

Second multigrain diffraction training session for TIMEleSS members

Second training session on multigrain analysis, February 2019

The TIMEleSS team is holding its second training session on multigrain diffraction data processing. The session takes place on Feb 11-15 at the Université de Lille, in France. Participants (left to right on the image) include Julien Chantel, our guest Agnès Dewaele, Sébastien Merkel, Jeffrey Gay, Sergio Speziale, Estelle Ledoux, Matthias Krug, and Carmen Sanchez-Valle.

The session is an opportunity for all members to get trained in multigrain diffraction data processing but also to standardize our data workflow strategies.

More to come soon with the TIMEleSS-tools developed at this occasion!

Deep Earth Mini Symposium at WWU Münster

Federica Rochira and Matthias Krug at the Deep Earth Mini Symposium in Münster in December 2018

Federica Rochira and Matthias Krug presented posters at the Deep Earth Mini Symposium in Münster. The symposium was organized by TIMEleSS PI Tine Thomas.

This one-day meeting attracted an international and interdisciplinary group of deep Earth scientists, PhDs and Master students, with keynote talks given by Jennifer Jackson (Caltech), Jeroen Ritsema (University of Michigam) and Sebastian Rost (University of Leeds), and a poster session with wine and cheese.

The full program of the symposium can be found online in the following document.
