The TIMEleSS project aims at studying interfaces in the Earth’s mantle combining observations from seismology, mineral physics experiments, microstructures, and wave propagation modeling. It is supported through a bilateral grant, from the ANR in France and the DFG in Germany. The project is led by Sébastien Merkel and Nadège Hilairet at the Université de Lille, Christine Thomas and Carmen Sanchez-Valle from the Westfälische Wilhelms-Universität, Münster, and Sergio Speziale from the Deutsche GeoForschungsZentrum, Potsdam.

Project launch: March 2018
Duration: 36 months
Total ANR-DFG funding: 700 000 €

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.

Frederica Rochira at EGU 2019 in Vienna

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.

Synchrotron beamtime for TIMEleSS

Samples for experiments at PETRA III

The TIMEleSS group is at the PETRA III synchrotron this week-end. Matthias Krug, Estelle Ledoux, Jeff Gay, Julien Chantel, Carmen Sanchez-Valle, Sébastien Merkel, and special guest Anastasiia Zadoia will be spending some time at P02.2…

Two months of sample synthesis, polishing, coating, cutting, and 10 diamond anvil cells loaded.

Nights will be shorts for the next four days. Let’s cross fingers, we need data for our next multigrain diffraction datathon!

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.
