Research associate @cerege_officiel (@earth_cerege) Cosmogenic nuclide 10Be and paleomagnetism, among other things
Aix-en-Provence, France
Joined June 2011
Update on #10Be production & geomagnetic dipole variations over the 20 – 60 ka interval and the Laschamp excursion. Is the #Laschampexcursion an #abortedreversal? No large-scale dipole collapse during the #MonoLake excursion. @earth_cerege @cerege_officiel

Tristesse 😢🧭🌍
#Disparition Hommage à Jean-Pierre Valet, décédé le 28 août 2024 des suites d’une longue maladie, qui n'aura eu de cesse d'allier des méthodologies et des concepts complexes pour résoudre des questions fondamentales sur la dynamique de notre 🌍 interne. 👉 https://t.co/nbeO7Lp19x

Good memories of Brazil, congrats @paularodzor! 🌳🌎🇧🇷🧪
Very happy to share our #paleo research on the Colônia crater in #Brazil! This time an early #Pleistocene record (1.5 to 1.3 Ma). We show how sensitive was the Atlantic Forest to glacial-interglacial climatic changes.@mariepledru @Colonia_Drill

This Thursday 3 PM (UTC+2), I will discuss the versatility of atmospheric 10Be for chronostratigraphy and geochronology. Earth's magnetic field intensity variation is of course on the menu. 🧲🌍

En parlant de Jean-Pierre et de l'hypothèse liant le Laschamp et l'extinction des Néandertaliens, qu'on soit d'accord ou pas, il aurait été élégant de citer ce papier... =>

Jean-Pierre Valet aimerait, lui, corroborer les pics de rayonnement cosmiques observés sur le kauri avec d'autres archives. => https://t.co/GL1K9LLuPa 👍

"Aucun indice sérieux d'un changement climatique majeur n'est retrouvé à cette période dans les glaces de l'Antarctique ou du Groenland, ni dans les spéléothèmes sous les Tropiques", souligne de son côté Quentin Simon.

Our last article in PNAS (Christ et al., 2021) @drewchrist_geo @ericsteig
https://t.co/R8YrgUQNOP indicates that the collapse of the Greenland Ice Sheet is more probable under a +2°C warming compared to a +1.5°C warming. #Greenland #paleoclimate #sealevel #ParisAgreement
