About Jérôme Gaillardet

Jérôme Gaillardet received his PhD from Paris University where he worked with Bernard Dupré and Claude Allègre on the geochemistry of the Congo and Amazon rivers.

He is currently professor of geochemistry at the Institut de Physique du Globe de Paris, IPGP, where he is leading a team working on the geochemistry of rivers, used as sensors of environmental and geological changes.

Jérôme’s major scientific contributions have been:

  • the inversion of large river geochemical data in order to calculate global rates of chemical denudation and atmospheric CO2 consumption by weathering reactions and their global control. 
  • the chemical composition of large river sediments and the concept of steady state of erosion based on geochemical mass budgets.
  • the role of acidity production by the natural acids (sulfuric and carbonic) for rock weathering.
  • the development of a method of boron isotope analysis in rivers and the contribution to the isotope geochemistry of boron, as a paleopH index, in the ocean, rivers and soils.
  • the development of new isotopic tracers like Zn, Cu and B isotopes as tracers of anthropogenic pollution in rivers.
  • the rejuvenation of the importance of carbonate weathering on a global scale.
  • the contribution to the international development of the CZEN network by initiating a river basin monitoring site in the Lesser Indies and collaborating with Puerto Rico.
