Climate-controlled submarine landslides on the Antarctic continental margin.

Published in Nature communications

Antarctica's continental margins pose an unknown submarine landslide-generated tsunami risk to Southern Hemisphere populations and infrastructure. Understanding the factors driving slope failure is essential to assessing future geohazards. Here, we present a multidisciplinary study of a major submarine landslide complex along the eastern Ross Sea c...

Biogeomorphology of Ireland's oldest fossil forest: Plant-sediment and plant-animal interactions recorded in the Late De...

The mid-Palaeozoic was a significant interval in the evolution of plants, during which their biogeomorphic influence on terrestrial landscapes increased dramatically. The products of plant-sediment interactions are well known from Carboniferous strata, but earlier evidence dating to the initial rise of arborescent trees in the Devonian is less comm...

Impact of Lithological Variation and Topology on the Connectivity and Intensity of Fracture Networks in Carbonates

Assessing fracture network connectivity in reservoirs remains a challenging task because of the complex nature of fracture networks at various length scales, which significantly impacts fluid flow behavior. Outcrop studies are essential for understanding subsurface fracture networks because intersecting fracture sheets' length, orientation, height ...

Fluvial Megafans on Earth and Mars

Megafans are partial cones of river sediment that reach unexpectedly large dimensions, with the largest on Earth being 700 km long. Due to recent developments in space-based observations, global mapping efforts have shown that modern megafan features cover vast landscapes on most continents. This book provides a new inventory of nearly 300 megafans...

Revised Minoan eruption volume as benchmark for large volcanic eruptions

Published in Nature Communications

The authors use seismic and sedimentology data to estimate the volume of the Minoan eruption. The results show that the Plinian phase contributed most to the distal tephra fall, and that the pyroclastic flow volume is significantly smaller than previously assumed.

Sediment delivery to sustain the Ganges-Brahmaputra delta under climate change and anthropogenic impacts

Published in Nature Communications

The potential for enhanced sediment delivery to the Ganges-Brahmaputra delta exists, but it alone is insufficient to sustain the system. The delta may be resilient to climate change, but only in the absence of dam construction and water diversions.

Caractérisation des hétérogénéités réservoirs dans les carbonates continentaux du Cénozoïque du bassin de Paris : Liens ...

L'intérêt porté aux carbonates continentaux n'a cessé de croitre ces dernières années pour leur usage comme réservoir géologique (géothermie, eau, stockage), comme matériaux (pierre de construction) ou pour la géotechnique, notamment dans la métropole du Grand Paris. Cependant, ces carbonates sont très hétérogènes, causant des variations spatiales ...
