Partners and their databases

H+ network

The H+ network is the French long-term observation system for hydrogeological research and was created in 2002. It hosts international teams developing novel subsurface monitoring and imaging techniques, such as the ENIGMA ITN project. The H+ network takes part in OZCAR on subsurface data. H+ experimental site in Ploeumeur hosted the ENIGMA second workshop in October 2017.

TERENO network

Established in 2008, TERENO is a German long-term research program on consequences of global change for terrestrial ecosystems and its socioeconomic implications. ENIGMA ESR are working on several TERENO-linked experimental sites.

HOBE Observatory

HOBE is the Danish hydrological observatory, established in 2007. It is working a an interdisciplinary research programme, with a strong training activity. ENIGMA ESR are working on several HOBE sites.
