Chemical tracers of ocean circulation
Chemical tracers have become a key tool for oceanographers over the last few years, to study ocean circulation. Our team implements usual physical tracers as well as two types of chemical tracers:
- natural tracers, or nutrients (silicates, nitrates, phosphates), which can show constant relative concentrations in the deep ocean
-transient tracers (CFCs, CCl4), which are anthropogenic compounds whose concentrations have widely fluctuated over the last decades.
