Rare Earth Element (REE) concentrations and Nd isotopic compositions (εNd) of five new seawater profiles scattered across the Rockall Trough (North-East Atlantic, Fig.

With a view to understanding the dynamics of ancient trade and agrobiodiversity, archaeobotanical remains provide a means of tracing the trajectories of certain agricultural commodities.

Ongoing ocean acidification is known to be a major threat to tropical coral reefs. To date, only few studies have evaluated the impacts of natural long-term exposure to low-pH seawater on the chemical regulation and growth of reef-building corals.

Soil carbon dynamics is strongly controlled by depth globally, with increasingly slow dynamics found at depth. The mechanistic basis remains however controversial, limiting our ability to predict carbon cycle-climate feedbacks.

Few studies have focused on Arenosols with regard to soil carbon dynamics despite the fact that they represent 7% of the world’s soils and are present in key areas where food security is a major issue (e.g., in Sahelian regions).

Ice core and marine archives provide detailed quantitative records of last glacial climate changes, whereas comparable terrestrial records from the mid-latitudes remain scarce.

​Une équipe du LSCE (CEA-CNRS-UVSQ) a participé à des travaux de reconstruction des températures et précipitations pour les continents, à la dernière époque glaciaire, à partir de granules de vers de terre.

​Deux chercheuses du LSCE (CEA-CNRS-UVSQ) ont publié un article dans un numéro hors-série d'Archeologia à l'occasion de l'inauguration du fac-similé de la grotte Cosquer dans le département des Bouches-du-Rhône.

This Open Access volume highlights how tree ring stable isotopes have been used to address a range of environmental issues from paleoclimatology to forest management, and anthropogenic impacts on forest growth. It will further evaluate weaknesses and strengths of isotope applications in tree rings.

Along the coasts of northern Alaska, in a treeless tundra environment, the primary wood resource for coastal populations is driftwood, a seasonal and exogenous resource carried by the major rivers of western North America.

Hydroclimate variability in tropical South America is strongly regulated by the South American Summer Monsoon (SASM). However, past precipitation changes are poorly constrained due to limited observations and high-resolution paleoproxies.

L’anticipation des effets du changement climatique est désormais un objectif de plus en plus partagé.

Notre-Dame de Paris, the so famous Catholic cathedral standing on Ile de la Cité in Paris, was built in 1163, largely completed by 1260, then frequently modified in the following centuries until a major restoration between 1844 and 1864.

Tree-ring width (TRW) chronologies have been widely and long-time used to reconstruct past climate variations in the Andes in South America. The use of tree-ring isotopic chronologies is still not widespread in this region although they have proved to be very efficient climate proxies.

​Une collaboration franco-espagnole impliquant le LSCE (CEA-CNRS-UVSQ) a analysé deux stalagmites de la grotte de Nerja (Andalousie) afin d'éclairer les archéologues.

Mardi 27, mercredi 28 et jeudi 29 septembre 2022, Camille Asselin, Edouard Régnier et Jérémy Jacob ont été accueillis par la Division Curage du Service Technique de l'Eau et de l'Assainissement (Direction de l'Eau et de la Propreté) de la Ville de Paris pour visiter les bassins de dessablement du secteur Est du réseau d'assainissement.

Jérémy Jacob et Sigrid Mirabaud 19 septembre 2022 à l'Institut National de l'Histoire de l'Art (Paris) - 2 Rue Vivienne, 75002 Paris Journée Thématique organisée par le réseau CAI-RN, avec le soutien de la MITI/CNRS L'objectif de la Journée Thématique était de sensibiliser la communauté de l'archéométrie et de la conservation aux sens.

Jérémy Jacob et Edouard Régnier En octobre 2021, des chercheures et chercheurs du Laboratoire des Sciences du Climat et de l’Environnement (LSCE, Gif-sur-Yvette), de l’Institut des Sciences de l’Évolution de Montpellier (ISEM) et de l’Université Fédérale du Ceara (Brésil) ont parcouru l’état du Piauí pour prélever des carottes de sédiments lacustres et des échantillons de surface.

During the Maya early Anthropocene (2000 BCE - 1000 CE) in Mesoamerica, socio-environmental interactions contributed to the rise and decline of the ancient Maya civilization.
