Study of the Earth’s Deep Interior

View from the rooftop of ETH ZürichSEDI 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

See you in Zürich for a wonderful week!

TIMEleSS at the AGU Fall Meeting

AGU Fall Meeting 2020

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!

Presentations from the TIMEleSS project include

Enjoy your AGU fall meeting!

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!

 

2nd Deep Earth Mini Symposium in Münster

TIMEleSS members at the 2nd Deep Earth Mini Symposium in Münster (18 Nov. 2019)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.

GeoMünster 2019 “Earth! Past, Present, Future”

GeoMünster 2019 "Earth! Past, Present, Future"

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!

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!

Estelle Ledoux presents her work at the Colloque de la Sfµ 2019

Colloque de la Sfµ 2019

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.

TIMEleSS PI giving an invited presentation at the Diamond light source

Diamond High-Pressure Workshop, 26/02/2019 - 27/02/2019

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.
