Methane seeping induced by natural gas hydrate dissociation is ubiquitous in deep-sea environment, which influences the global methane and carbon budget. Nevertheless, the phase equilibrium char-acteristics that control the stability of hydrate formation during the bubble ebullition process in the in-situ multi-component environment remain unclear....

We investigated the influence of high-CO2 hydrothermal seepage on element cycling, early diagenetic processes, and meiobenthic communities in sediments of a coral reef in Papua New Guinea. Based on fluid flow velocities, determined from temperature gradients, and element concentrations, the solute fluxes from the seeps were estimated, showing that ...

In order to estimate the resuspension of the particles empirically, it is necessary to carry out a homogeneous distribution of the particles on the tested surfaces. Thus, in many studies, seeding or deposition in experimental chambers is performed to quantify initial concentrations for subsequent resuspension experiments. The current study was carr...

Understanding evapotranspiration and its long-term trends is essential for water cycle studies, modeling and for water uses. Spatial and temporal analysis of evapotranspiration is therefore important for the management of water resources, particularly in the context of climate change. The objective of this study is to analyze the trend of reference...

Dans le monde, environ 7 millions de décès annuels sont dus à la pollution de l'air. Parmi tous les polluants, les particules ultrafines (UFP) provoquent des effets négatifs importants. Dans cet article, la dispersion de l'UFP est étudiée dans le sillage des modèles de voitures caractérisé par différents angles d'inclinaison arrière. Les vitesses e...

Worldwide around 7 million annual deaths are due to air pollution. Among all pollutants, Ultrafine Particles (UFP) cause strong adverse effects. In this paper, the dispersion of UFP is studied in the wake of car models characterized by different rear slant angles (?). Velocities and UFP concentrations are collected in a wind tunnel. The influence o...

Cette thèse est consacrée à l'analyse de la fiabilité du tablier du viaduc de Millau, un pont à haubans situé dans le sud de la France. Le but principal est d'extrapoler dans le temps les charges et les effets de charges sur le pont afin d'observer la fiabilité de différentes parties de la structure pendant sa durée de vie. Le viaduc de Millau est ...

A three-dimensional (3D) wind profiling Lidar, based on the latest high power 1.5 µm fiber laser development at Onera, has been successfully flown on-board a SAFIRE (Service des Avions Français Instrumentés pour la Recherche en Environnement) ATR42 aircraft. The Lidar called LIVE (LIdar VEnt) is designed to measure wind profiles from the aircraft d...
