Enjoy your AGU fall meeting!
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!
TIMEleSS 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!
The fall meeting of the American Geophysical Union is the largest international Earth and space science meeting in the world with approximately 25000 attendees.
2019 is a special year that marks the Centennial for AGU. Monday dec. 9th was a celebration day for Earth Interior studies with a special Centennial session in which TIMEleSS PI S. Merkel was in charge of organizing and chairing part of the day.
Things return to a normal AGU now, with the usual layout for sessions and presentations. The TIMEleSS project will be presented on Thursday morning in session DI41C – A Deep Dive into Lowermost Mantle Processes. Please come by to see the state of our current research!
The second Deep Earth Mini Symposium was held at the Institute for Geophysics of the University of Münster on November 18th 2019.
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.
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 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.
See you in Münster in September!
Frederica Rochira was at the EGU General Assembly 2019 in Vienna. EGU brings together geoscientists to one meeting covering all disciplines of the Earth, planetary and space sciences. The meeting is held yearly in Vienna, Austria, and, in 2019, it was attended by 16,273 scientists from 113 countries.
Frederica Rochira presented her works entitled Detecting structures in the mid mantle using out-of-plane signals in the multidisciplinary session Dynamics of the mantle in the Earth and planetary bodies: from magma oceans to the present day.
The session, co-organized by TIMEleSS members, included four oral presentations on Thursday as well as 12 PICO presentations early afternoon on Friday. The session was an opportunity for scientists of various fields of geosciences (seismology, geodynamics, mineral physics) to present the results of her works and discuss their implications for understanding the dynamics of mantles, on Earth and other planetary bodies.
S. Merkel gave an invited presentation at the Diamond Light Source workshop on high pressure research, in the UK.
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.
This week, two of the TIMEleSS PI’s are attenting the Final Workshop of the CREEP ITN at the Ecole de Physique des Houches, in France. The workshop is held from 27 January to 1 February 2019 in the town of Les Houches, in the Chamonix valley.
The CREEP ITN is a EU funded project that proposed an interdisciplinary and multiscale approach to study the origin of rheological complexity in Earth and analogous materials and how it controls the dynamics of our planet, including natural and human-induced seismicity, and affects a large range of industrial applications, from energy production and waste storage to production of high-performance glasses. It included a number of partners, from academia and industry with over 10 PhD fellowships. More details can be seen at the CREEP ITN website.
The TIMEleSS project, its objectives, and some results were highlighted in a an hour long invited presentation regarding Phase transitions in the mantle by PI S. Merkel.
