SEDI is an international scientific organization dedicated to the Study of the Earth’s Deep Interior. The ultimate goal of SEDI is an enhanced understanding of the past evolution and current thermal, dynamical and chemical state of the Earth’s deep interior and of the effect that the interior has on the structures and processes observed at the surface of the Earth.
The 2022 Symposium of SEDI is being held in Zurich, Switzerland, from 11th to 15th of July, 2022. TIMEleSS participants C. Thomas, S. Merkel, and J-K Magali are in to discuss their latest results and understanding of deep Earth processes.
TIMEleSS presentations include
On the hunt for seismic anisotropy in the lower-mantle from the crystallographic preferred orientation of bridgmanite aggregates induced by large-scale flow, by John Keith Magali et al.
Microstructures and anisotropy in pyrolite at lower mantle pressures and temperature, by Jeffrey P. Gay, Estelle Ledoux, Matthias Krug, Julien Chantel, Carmen Sanchez-Valle, Sébastien Merkel
Seismic anisotropy due to textures above and below the 410 km discontinuity, by Morvarid Saki et al
TIMEleSS members met virtually in June 2021 for a virtual meeting on crust subduction. The meeting was led by Matthias Krug, PhD student at WWU Münster, and currently visiting the Université de Lille for 6 months.
The meeting was an occasion for Matthias to present his work and get feedback from the rest of the group.
The Fall Meeting of the American Geophysical Union is on online and everywhere in 2020! The AGU Fall Meeting typically attract over 25 000 registrants from all over the world, in a conference center somewhere in San Francisco, New Orleans, or somewhere else in the United States. This year, the Fall Meeting is fully online and TIMEleSS members are happily joining in for presenting their latest results!
The 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!
The one day symposium has presentations from local and international speakers who all came to Münster for a day of science and discussions. The workshop was organized by TIMEleSS PI C. Thomas.
TIMEleSS PI S. Merkel gave a presentation entitled Phase transitions in the lowermost mantle : Effect on microstructures and seismic reflections. TIMEleSS students F. Rochira and M. Krug presented posters on their most recent works.
TIMEleSS members will be at GeoMünster 2019! GeoMünster 2019 is the Annual Conference of the Deutsche Geologische Gesellschaft – Geologische Vereinigung (DGGV – The German Geological Society) and the Deutsche Mineralogische Gesellschaft (DMG – The German Mineralogical Society). It will be held 22–25 September 2019 at the Münster University, Germany, and will be organized and by the Institutes for Geology and Paleontology, Mineralogy, and Planetology.
TIMEleSS members are organizing a session entitled Minerals in the depths: an experimental approach, with a oral presentation of TIMEleSS student Matthias Krug and a poster from our partner Iliya Kupenko.
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!
The Colloque de la Sfµ is the meeting of the French microscopy society. It is held annually and mostly focuses on electron microscopy techniques.
Estelle Ledoux, PhD student partially financed by TIMEleSS, presented her results on EBSD analyzes of plastically deformed polycrystalline MgO. The work is a result of a collaboration between the group at the University of Lille and that of L. Miyagi at the University of Utah.
The results of the work will be useful for the TIMEleSS project for addressing properties of the Earth’s lower mantle.
The workshop aims to bring together high-pressure researchers with different experimental expertise and to highlight the latest developments in high-pressure techniques across synchrotron beamlines.
S. Merkel gave a presentation entitled “In situ study of phase transformation mechanisms using multigrain crystallography“. The presentation was an opportunity to present the science at the foundation of the TIMEleSS project, its objectives, and some results.
Matthias Krug and Frederica Rochira gave presentation in front of their institute in Münster.
Matthias presented his work on Jan 8th and Frederica on Jan 21st. These presentations were an opportunity for the students to display their works in front of their colleagues, get feedback, and new ideas for their project.
Estelle Ledoux and Jeff Gay presented they current work at the PhD student days for the UMET lab in Lille. The symposium is organized yearly in January.
This one-day meeting is an opportunity to discover the work of current PhD students and the evolution of research in the lab. It is an opportunity for exchanges between students and researchers, exchange ideas, and build strong future collaborations.
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.
TIMEleSS PI Sébastien Merkel is attending the meeting and will present one TIMEleSS related poster,
Multigrain Crystallography Study of Phase Transformation Microstructures in Deep Earth Minerals : Application of the Perovskite to Post-Perovskite Transformation
Sebastien Merkel, Christopher Langrand, Nadege Hilairet
Wednesday, 12 December 2018, 13:40 – 18:00
Convention Ctr – Hall A-C (Poster Hall)
Federica Rochira gave her first talk at the Institute of Geophysics in Münster. She presented her part of the TIMEleSS project and the first results about the out-of-plane reflections in the mid-mantle. The seismology group of Münster was present but also Carmen and Matthias of the Institute of Mineralogy, also involved in the TIMEleSS project.
