Mars didn’t dry up in one go
The Perseverance rover has just landed on Mars. Meanwhile, its precursor Curiosity continues to explore the base of Mount Sharp (officially Aeolis Mons), a mountain several kilometres high at the centre of the Gale crater.

Raman spectroscopy to determine CO2 solubility in mafic silicate melts at high pressure: Haplobasaltic, haploandesitic and approach of basaltic compositions
Publication of the LGL-TPE in the journal Chemical Geology on November 5, 2021. CO2 degassing of mafic silicate melts is an important part of the terrestrial carbon cycle, at mid-ocean ridges, oceanic hot spots, or in the middle of continents.

2 months at sea to explore the Southern Ocean’s contribution to climate regulation
To better understand the sequestration of atmospheric CO2 in the ocean, and especially how the chemical elements essential to this storage are supplied, transported and transformed by the oceans, is the goal of the SWINGS oceanographic cruise.

The Le Teil earthquake provides new insights on seismic risk in France and Western Europe
O n 11 November 2019 , a magnitude 5 earthquake occurred near the village of Le Teil in the Rhône River Valley in southern France producing an unexpected surface rupture with ground displacement.

Mayotte: launch of a global study on this fragile and unique ecosystem
The CNRS and Mayotte's Centre Universitaire de Formation et de Recherche (CUFR) have just approved the creation of a global ecology study site on the Mahoran archipelago.

The Kerguelen oceanic plateau sheds light on the formation of continents
How did the continents form? Although to a certain extent this remains an open question, the oceanic plateau of the Kerguelen Islands may well provide part of the answer, according to a French-Austra

Heading to Barbados to investigate two unknowns in the climate equation
A major airborne and oceanographic mission off the Caribbean island of Barbados is preparing to study two major climate unknowns: trade wind cumulus clouds and mesoscale eddies in the ocean.

Mercury in the Arctic Ocean: Stopover in the tundra
The Arctic Ocean and its fauna are far from major sources of pollution. So why are they so contaminated with mercury? This mystery has just been solved by an international team including researchers from the CNRS, the Desert Research Institute, and the University of Colorado.

Subtropical climate conditions and mangrove growth in Arctic Siberia during the early Eocene
The early Eocene (ca. Ma) was an interval of exceptional warmth with reduced pole-to-equator temperature gradients.
