Les capteurs de transport de neige par le vent au banc d'essai [PDF]

Sciences, Eaux & Territoires, 2010
Le transport de la neige par le vent entraîne la formation de congères, augmente le risque d'avalanches et limite la visibilité. Afin d’améliorer la prévision du phénomène et de développer une ingénierie de protection, les acteurs locaux de la prévention

Haies et boisements pare-congères : de la théorie à la pratique [PDF]

Sciences, Eaux & Territoires, 2010
Lorsque la neige et le vent s'associent, ils créent des congères qui vont gêner la circulation sur les routes et les chemins de montagne. Pour lutter contre ce problème, l'implantation de haies et de boisements apparait comme une solution écologique et ...

Modeling the Shape and Velocity of Magmatic Intrusions, a New Numerical Approach

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 3, March 2023., 2023
Abstract Dykes are magma‐filled fractures propagating through the brittle crust. Understanding the physics of dyking process is essential to mitigate the volcanic hazard associated with the opening of new eruptive fissures at the surface. Often, physics‐based models view either fracturing of the host rock or viscous flow of the magma as the dominating ...

Conch geometry, ontogeny and dimorphism in the Early Bajocian ammonoid Stephanoceras from Normandy, France

Lethaia, Volume 54, Issue 5, Page 775-792, December 2021., 2021
A large suite of specimens belonging to the Early Bajocian Stephanoceras from Évrecy (Normandy, France) displays wide variation in conch and sculpture. The quantitative analysis of the conch geometry and its ontogeny on the basis of more than 50 sectioned specimens reveals major problems in the separation of species within the assemblage; clear ...

Gas Geochemistry at Grande Comore and Mayotte Volcanic Islands (Comoros Archipelago), Indian Ocean

Geochemistry, Geophysics, Geosystems, Volume 22, Issue 8, August 2021., 2021
Abstract The Comoros archipelago is an active geodynamic region of intra‐plate volcanism within which the youngest and oldest islands (Grande Comore and Mayotte respectively) are characterized by recent volcanic activity. The frequent eruptions of the large shield volcano Karthala on Grande Comore (last eruption 2007), and the recent birth of a large ...

ALEXANDER VON HUMBOLDT'S CLIMATOLOGICAL WRITINGS

German Life and Letters, Volume 74, Issue 3, Page 371-393, July 2021., 2021
ABSTRACT Humboldt is often credited with being the forerunner of modern ecology and environmentalism and the founder of modern comparative climatology – without having written a single book on climate. His contributions can be found in the 800 articles and essays that he published in scientific journals.

The palaeobiology of belemnites – foundation for the interpretation of rostrum geochemistry

Biological Reviews, Volume 95, Issue 1, Page 94-123, February 2020., 2020
ABSTRACT Belemnites are an extinct group of Mesozoic coleoid cephalopods with a fossil record ranging from the early Late Triassic [about 240 million years ago (Mya)] to the Cretaceous/Palaeogene boundary (65 Mya). Belemnites were widely distributed, highly abundant and diverse, and an important component of Mesozoic marine food webs.

InSAR Evidence of Small‐Scale Faults Activated During Rift Zone Intrusions at Piton de la Fournaise Volcano

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Volcanic edifices show complex internal structures including discontinuities at different scales. These discontinuities can act as zones of weakness and are closely linked to volcanic activity distribution and associated hazards, making their detection and monitoring essential. In this study we investigate the presence of small‐scale faults on
