Publication involving a former ENS de Lyon PhD candidate and the EVS laboratory, in the journal Marine Geology . Earliest Evidence of Port-Related lead pollution in Bronze Age Greece First discovery of brown coal in a stratigraphic context at the end of the Bronze Age Lechaion's harbour archaeological chronology pushed back by at least 5 centuries New perspectives on regional economy and trade during the LBA/EIA transition Lechaion in Corinth, Greece, is the largest ancient port in Greece.

The ocean's capacity to store atmospheric carbon dioxide is some 20% greater than the estimates contained in the latest IPCC report 1 . These are the findings of a study to be published in the journal Nature on December 6, 2023, led by an international team including a biologist from the CNRS 2 . The scientists looked at the role played by plankton in the natural transport of carbon from surface waters down to the seabed.

Researchers from INRAE, Universidad del Desarrollo (Chile), University of Geneva and University of Grenoble developed a new method to assess the risk associated with rockfalls in the mountains, taking into account various triggering factors and all the issues exposed. They successfully tested it in the Chilean Andes.

The largest floating ice shelves in the polar ice sheet have lost more than a third of their volume since 1978.

Using a new analysis method for satellite images, an international research team, coordinated by the French Alternative Energies and Atomic Energy Commission (CEA) and INRAE, mapped for the first time annual changes in global forest biomass between 2010 and 2019. Researchers discovered that boreal and temperate forests have become the main global carbon sinks.

The North Alfeo Fault runs across the seafloor at the base of Mount Etna, the tallest and currently most active European volcano, next to an urban area with a population of one million. The Focus project seeks to better understand seismic processes in action and allow for surveillance of movement along the fault.

A newly identified process of natural iron fertilization in the ocean fuels regional CO2 sinks. This was demonstrated by a study published May 25 in Science and co-authored by 25 researchers from the Tonga project. This project was led by two researchers from the IRD and CNRS, with over 90 scientists from 14 French laboratories based in mainland France, New Caledonia, and 6 international universities.
