The earth sciences MEET project awarded the ERC Synergy Grant 2019
Published on October 14, 2019
The MEET project (Monitoring Earth Evolution Through Time) will receive 12.8€ over 6 years to investigate Earth’s evolution since its creation. The project is led by 3 researchers from 3 institutions in France, Germany and USA, and is held by the Université Grenoble Alpes’ Alexander Sobolev, professor at the ISTerre laboratory (CNRS/IRD/UGA/USMB/IFFSTTAR).

Plate tectonics: crustal recycling in the deep mantle would have started 3.3 billion years ago
Published on July 18, 2019
Ile des Bermudes An international team of scientists, led by geochemists from the Institute of Earth Sciences at the Université Grenoble Alpes (UGA), presented evidence of an early and unexpected start of crustal recycling in the deep mantle.
Global recycling of oceanic crust from the surface of Earth down to the deep mantle and then back to the surface is one of the major features of the plate tectonic regime, which makes our planet unique in the Solar system. Just when this process (...)
New clues about carbonate crystallization kinetics at interfaces
Published on June 13, 2019
The formation of minerals from aqueous solutions is a widespread natural phenomenon that controls mass transfers within the lithosphere, impacting elemental cycling –mostly through interactions with living organisms. Crystallization phenomena have also a high industrial relevance, e.g., for the development of new anti-scaling agents or the synthesis of biomimetic materials.
The process of mineral formation usually involves two consecutive steps –nucleation and growth- that are controlled by (...)
An alternative explanation for the origin of Bermuda
Published on May 28, 2019
Lavas of Bermuda island likely present the first sample of the melt from the Earth mantle transition zone. A study involving the Institut des Sciences de la Terre / OSUG. The island of Bermuda is the surficial expression of a 1,500-km-long topographic swell, which rises 1 km above a 110–140-Myr-old oceanic crust of Atlantic Ocean. Like many ocean volcanic islands, Bermuda has been historically explained as being derived from a mantle plume- the jet of hot mantle material rising from the (...)

Published on April 16, 2019
On March 28th, the European Research Council (ERC) published the list of its Advanced Grants awardees 2019. Among the 222 projects selected (out of 2,052 submitted) — including 31 based in France and 10 in the Earth and Environmental Sciences — is the project COOLER (Climatic Controls on Erosion Rates and Relief of Mountain Belts) proposed by Peter van der Beek, professor at the ISTerre / OSUG. It has been suggested that slow and continuous global cooling beginning in the Cenozoic era (the (...)

Published on March 07, 2019
Will the murmurs of the sea ice allow us to better predict its evolution at the North Pole?
The sea ice is disappearing with global warming, and if the trend is clear over the last few decades, scientists are still wondering about the speed of this disappearance, which seems much faster than models predict.
To better assess the quality of polar ice (its thickness, degree of fracturing), a team of ISTerre scientists led by Ludovic Moreau is leading a reconnaissance and test expedition in (...)
Why is the magnetic North moving?
Published on March 05, 2019
The newspaper Le Monde offers a popularization video (in french only) on the Earth’s magnetic poles, especially the magnetic North, which has been moving since the 19th century and is now approaching Siberia at a speed of 55 km per year.
The ISTerre Geodynamo team was called upon to produce this video, since it includes Henri-Claude Nataf, CNRS research director, and animations from the numerical simulations of the core carried out by Nathanaël Schaeffer, CNRS (...)
RAP Award presented to Annie Souriau and Pierre-Yves Bard
Published on March 04, 2019
The 9th Biennale of the Permanent Accelerometric Network (RAP) brought together 76 participants from the scientific community of hazard and seismic risk in France in November 2018 in Lourdes. The event was organized with the support of the MTES, RESIF, the DDT of the Hautes-Pyrénées and the city of Lourdes.
On this occasion, the 1st edition of the RAP award was launched, which will now be awarded every 2 years by a 5-member commission. It rewards a remarkable contribution in engineering (...)
