Building the information system of the French Critical Zone Observatories network: Theia/OZCAR-IS

The French Critical Zone research infrastructure, OZCAR-RI, gathers 20 long-term observatories monitoring and sampling various compartments of the critical zone. Each observatory developed its own data management and distribution systems. The paper presents the common information system Theia/OZCAR IS that was built to make in situ observation FAIR (findable, accessible, interoperable, reusable). Within M-TROPICS, Norbert Silvera from iEES Paris participated to the paper that was just published in the Hydrological Sciences Journal.

Agricultural groundwater with high nitrates and dissolved salts given to pregnant mice alters brain development in the offspring

This new paper, at the interface between environment and health, shows that groundwater contaminated by agricultural inputs from the Indian site of Berambadi (M-TROPICS observatory), significantly impacts the brain development of mice when given to pregnant or lactating mice: fewer neurons, fewer astrocytes (white blood cells in the brain), and more dead cells in the […]

Decay Rate of Escherichia coli in a Mountainous Tropical Headwater Wetland

Fecal indicator bacteria like Escherichia coli (E. coli) are widely used to assess water contamination, but their behavior in tropical ecosystems is poorly documented. The main objectives of this study led by Paty Nakhle, PhD student at GET in collaboration with iEES Paris, were to: (i) evaluate decay rates (k) of the total, particle-attached and […]

The M-TROPICS CZO releases long-term meteorological, hydrological, sedimentary geochemical, and land use datasets in Cameroon, Lao PDR, and India

The CZO M-TROPICS (Multiscale TROPIcal CatchmentS) investigates the response of tropical catchments to global change based on long-term collection of meteorological, hydrological, sedimentary, geochemical, and land use data in partnership with academic and governmental institutions in various tropical countries. M-TROPICS includes in particular the experimental watersheds of Nyong in Cameroon (1994-), Houay Pano in Lao […]
