Scientific objectives
The team’s objectives are threefold:
- To characterise the chemical fluxes (intensity, associated processes) at the ocean interfaces (continental margins, rivers, submarine groundwater discharge, air/sea interface, hydrothermal vents) which constitute chemical sources and/or sinks for the ocean,
- To constrain the circulation and dynamics of water masses (trajectories, transit time, vertical or horizontal mixing),
- To characterise the internal cycles of chemical elements in the water column. This requires, in particular, the study of dissolved/particle interactions, in relation to physical, chemical and biological processes.
Strategy and tools
Our strategy is based on the use of natural isotopic tracers analysed in samples collected in the ocean, laboratory experiments and modelling work. The tracers used are neodymium isotopes (radiogenic) and rare earths, iron isotopes (stable), radium, actinium and beryllium isotopes (radioactive). This strategy is based on a high expertise (both researchers and engineers), isotopic analyses of these trace elements in seawater and the use of our instrumental platforms.
Projects
We carry out studies in the framework of collaborative networks at national and international levels, in particular in connection with the GEOTRACES programme (e.g. PANDORA, GEOVIDE, TONGA, SWINGS campaigns, Mediterranean coastline).
