Fieldwork in Astipalae island in Greece to track Amorgos Tsunami (1956) which is the largest in Mediterranean Sea over the moderne period. Waves reach 30m of elevation!
We sample Sediment cores in Vathy Bay and on land to find onshore and offshore tsunami deposits.

Human and climate impacts on the alpine Critical Zone over the past 10,000 y | PNAS Agropastoral activities have impacted the habitable part of our planet—the “Critical Zone”—for thousands of years, triggering a major increase in s...

Our last publication in PNAS :
Agropastoral activity responsable for soil erosion and degradation in the Alps for the past 3800 years.

We reconstruct 10 000 y of soil evolution using sediment from Lake le Bourget àd the Lithium isotopes signature.

Our latest article on C sequestration over the past 150 years in Lake Aiguebelette show that C sequestration increased over the past 150 years due to local human disturbances. Even last decades, despite reduced nutrient loads following restoration.

This Thursday at 9 p.m., on French TV: France 5 will be rebroadcasting our film on the Iznik Basilica and seismic risk, combining archaeology, geology, and history. If you haven't seen it yet, I highly recommend it...

Coring at Lake La Thuile as part of the ANR ALPINE project, the objective being to understand the microbial diversity in the core for paleoclimatic reconstruction using lipid indicators produced by bacteria that are paleotemperature tracers.
Collaboration between @edytem.bsky.social and Metis

Inauguration of the French Coring Center attached to @osug-fr.bsky.social and hosted by @edytem.bsky.social
This national instrument park, supported by @cnrsecologie.bsky.social and @cnrs-insu.bsky.social, brings together continental and lake coring resources available to the scientific community.

A week of fieldwork with Earth science Bachelord students in Provence!

2 days of fieldwork in sedimentology and geodynamic of the NW French Alps with 2nd year of bachelor's degree at Université Savoie Mont Blanc.

Tsunami in Lake du Bourget 200 years ago!!
Our paper investigate the 1822 earthquake and resulting tsunami with a maximum wave of 2.5m and seiche for 4 days!
This numerical model allow us to propose the mecanism at the origin of Homogenite

This is by far the best modelling attempt of the Alpine Ice Field during the LGM (35-18 ka)! 🧊⌚

Thinner ice than previous attempts and better fit to the trimlines ❄️

Must read!

Installation of the monitoring on Lake Bourget with sequential sediment trap, temperature sensor, pH, conductivity and multiparameter probe!
As part of the ERC lake Switch and the ANR Alpine projects, we monitor 4 lakes in the NW Alps, Le Bourget du Lac, Aiguebelette, la Thuile and les Roberts
