Full textThe management of groundwater needs the estimation of the water residence time in aquifers, that can be done through the measurement of 14C radioactive decay of the Total Dissolved Inorganic Carbon (TDIC). This approach requires the knowledge of the TDIC 14C initial activity in recharge water. The groundwater mineralisation occurs in the Unsaturated Zone (UZ), where water interacts with CO2 and carbonates (if existing). We focus here on these interactions between both CO2, TDIC and carbonates. Two UZ have been investigated in France: the carbonate-free Fontainebleau sands and the carbonated Astian sands. Each site is equipped with a specific and experimental equipment to collect groundwater, UZ water, gas and solid matrix (organic matter and carbonate). The field-data are completed by a numeric approach in order to evaluate the different factors that define the CO2 isotopic composition at the bottom of the UZ. The 13C of CO2 depends on the mean 13C of produced CO2, the amount of produced CO2 and the diffusion coefficient of CO2. Subsurface seasonal variations of 13C disappear with depth. Before 1950, the 14C activity of CO2 can be assumed equal to atmospheric 14C level. After 1950, due to the atmospheric nuclear test, it depends on 14C activity of young organic matter and atmospheric CO2. The presence of carbonates leads to a 13C-enrichment of and a 14C-depletion of CO2 with depth, depending on the carbonate precipitation/dissolution flux, the amount of produced CO2 and the diffusion coefficient of CO2

Full textOn Earth, chemical weathering of silicate rocks is one of the mechanisms which consumes CO₂. All of these processes could be part of a negative feedback loop exerted on the Earth's climate, which would allow its regulation over geological time. Volcanic rocks have an important role since they are responsible for 30 pourcents of total CO₂ by weathering. The main challenge of this study is to identify the origin of CO₂ involved in the reactions of weathering of rocks of four active volcanic areas: the West Indies, Reunion, the Iceland and the Massif Central. In this aim, the delta13C of dissolved inorganic carbon (DIC) and riverine major ions were combined. In a first step, a reliable method of sampling and analysis of delta¹³C DIC has been developed. The analyse of nearly 200 samples from rivers, soil and solutions hydrothermal springs has highlighted that the magmatic CO₂ contributes significantly to the weathering of volcanic rocks, or even that it represents most of the CO₂ consumed by weathering in Iceland and Reunion, the other main reservoir of CO2 being biogenic CO₂. In addition, magmatic CO₂ appears to contribute to the weathering in different ways: either through hydrothermal contributions, or as diffuse magmatic CO₂. Both types of CO₂ would be associated with different schemes of weathering: soil type regime at low temperature, and the hydrothermal regime. The consequence of these observations is an overstatement of the rate of atmospheric CO₂ previously calculated by the mean of major ions in active zones. There seem to be a link between the proportion of CO₂ magmatic and rates of chemical weathering of rocks, which would indicate a control of weathering of active volcanic areas by magmatic CO₂. This underlines the need for measures of delta¹³CDic on a global scale, particularly in volcanic areas

Full textThe scientific objective of this work is to better understand the riverine carbon transfers to the oceans and to identify the different biogeochemical processes controlling these transfers using carbon isotopic signature (d13C). In order to do that, 25 watersheds have been investigated in the world, going from small catchments to large river basins. The results emphasize the major control of CO2 degassing to the atmosphere and of organic carbon oxidation (allochtonous and autochtonous) on the riverine d13CDIC. The average isotopic signature d13CDIC of the inorganic carbon riverine flux into the oceans has been estimated in this study to be -11,8. Finally, a first approach of a numerical model (d-Carb) has been developed to simulate the d13CDIC evolution in rivers
