POLARIS looks for a breakthrough in developing an imaging technique called induced polarization to locate critical metals (low grade ores plus W, Nb, Ta, Li, Sn, Be, Cs, Li, Sb, In, and Au) resources in the subsurface. High tech raw materials requires these metals and are of great strategic significance in relation to the overall resource balance of France and the European Union. There is an urgent need to reassess such mineralizations especially within the most promising ... En savoir plus ...

Coastal oceans and the services they provide are socially, economically and environmentally essential. These regions are subjected to major anthropogenic stressors, from local origin, and as a consequence of global changes. Among the disturbances are upper ocean warming, deoxygenation, acidification, overfishing, and various pollutions (heavy metals, waste waters ...). These disturbances can interact with each other, and spread/amplify in the ecosystem ...  En savoir plus ...

Seasonally inundated by nutrient-rich sediments from Andean headwaters, Amazonian “whitewater” river floodplains have long been centers for human settlements practicing a mixed subsistence system of cultivation, supplemented by fishing and hunting. Over the past several decades, unprecedented demographic and economic growth have challenged the traditional balance of resource use that sustains both humans and biodiversity on the floodplain and bordering upland. Threats to the integrity of Amazon floodplain habitats from dams, river navigation networks, extension of the agricultural frontier, and climate change are increasingly severe. However, to date, biodiversity scenarios for the Amazon have not considered these critical environments. En savoir plus ...
