2 main research units are involved in the ERO AgrHys:

  • The UMR 1069 INRA/Agrocampus SAS Soil Agro-hydro Systems which manages the observatory
  • The UMR 6118 CNRS/University of Rennes 1 Géosciences Rennes

Other research units member of the Observatory of Universe Sciences in Rennes OSUR are also invovled.

As a structure of Federal research, the Observatory of Sciences of the Universe CNRS, OSUR, pilots the researches on environment involving key laboratories of this topic within the scientific center of Rennes (CNRS, INRA, University of Rennes 1 and 2, Agrocampus Ouest) and provides a training mission in the field of earth sciences, ecology and the environment.

The OSUR ensures specific observation missions and global environmental systems over the long term. A unifying topic of the OSUR is the study of dynamic landscapes.

A national research infrastructure

OZCAR (Critical Zone Observatories: Research and Application) is a national distributed research infrastructure associating most of the French observation sites dedicated to the observation and monitoring of the Critical Zone, CZ, the thin outer venner of Earth’s continents extending from the top of the vegetation canopy down to groundwater.

OZCAR RI is supported by the French Ministry of Education and Research and, includes more than 60 highly instrumented sites/observatories for long-term measurements of biological, chemical and physical parameters of groundwater, river water, glaciers, soils, and wetlands in France and overseas. Each observatory focuses on one or more components of the Critical Zone but importantly OZCAR is covering most of the lateral and vertical compartments of the Critical Zone from mountains to costal areas.

These sites/observatories, funded by different research institutes, including universities, have been set up formerly to answer a local/regional scientific issue (ie. flood event prediction, acid rain resilience…) but they all share the overarching question issue of predicting the response of the CZ to perturbation ranging from the second to the millions of year.
