Carbonate dissolution by euendolithe cyanobacterium
Bioerosion is the process of destruction of rocks by living organisms. The bioerosion of biogenic carbonates by so-called "euendolithic" cyanobacteria (which live in rocks) is a major but poorly quantified process, causing, among other things, the disintegration of coral reefs. Euendolitic ...

Objective : characterize the chemical zonings in plagioclase and garnet related to fluid-rock interactions within a shear zone precursor
Geochemical data on rainfall and groundwater at Douala (Cameroon)
Stable isotopes (oxygen-18 and deuterium) data on rainfall at monthly and daily scales at Douala. Concerning groundwater, there is two sets of data: one on water stable isotopes (oxygen-18 and deuterium) and another one on major ion chemistry.
Jurassic Karst
Hydrogeochemical monitoring of karst springs in the Jura mountains
Majors, traces elements and strontium isotopes (87Sr/86Sr) of Cretaceous limestone and Quaternary marl - Jura Mountains
Majors, traces elements and 87Sr/86Sr ratio of Cretaceous limestone (Hauterivien) and Quaternary marls (two samples). The limestone was sampled in the Frasne-Bouverans syncline at proximity of the Forbonnet pealtand (Complexe tourbeux de Frasne-Bouverans). The marl was sampled in the underlying ...

This describes the temperature data acquired in a range of piezometers throughout the Forbonnet peatland (Jura Mountains, Frasne-Bouverans peatland complex).
SISMEAUCLIM
This project is based on three disciplines: seismology, hydrogeology and climatology. It aims to develop a new approach to monitor hydrogeological reservoirs, in particular karst aquifers, subject to extreme climatic events. The objective is to carry out 4D imaging during floods in a watershed ...

Pressure-Temperature quantification of continental crustal hydration - Colorado Plateau
Data acquired in collaboration with the University of Boulder in Colorado (U.S.A.) for the understanding of the Colorado Plateau elevation. These data sets include mineralogical, petrological, chemical, pressure-temperature modelisation and density evolution.
FIBROKARST
This project focuses on understanding karstic systems and particularly on the issue of recharge and transfer processes in these very heterogeneous and generally inaccessible environments. The objective is to use the fiber optic technique to identify the recharge points of the karstic aquifer of ...
