Use of remote cameras to monitor Sargassum seaweed washing up on beaches and coastline dynamics in the French Caribbean

Since 2011, the Caribbean has regularly been affected by masses of Sargassum washing up on beaches. This seaweed grows in the ocean and drifts under the influence of North Atlantic equatorial currents. Its accumulation and decomposition in coastal areas has harmful environmental, socio-economic and...

EuGeLi: Lithium extraction from geothermal brines in Europe

The European EuGeLi project funded by EIT Raw Materials aims to develop a process for co-producing lithium on an industrial scale from geothermal brines in the Rhine Graben.

RenovRisk: a research project on gravitational and erosion phenomena on La Réunion

Four multidisciplinary research teams from the BRGM worked together with the University of La Réunion on the RenovRisk-Erosion project to study gravitational and erosion hazards in La Réunion's mountain cirques, on the scale of the Rivière des Pluies / Salazie catchment basins.

REFLECT: Redefining geothermal fluid properties at extreme conditions to optimise future geothermal energy extraction

BRGM is one of the 14 partners involved in the REFLECT project, funded by the Horizon 2020 - Research and Innovation Framework Programme (Grant no: 850626). Launched in January 2020, the project aims to study geothermal fluids and their chemical reactivity during production phases, in order to...

AGORA: Optimization of the catchment area of the "100,000 m³/day line" in Bordeaux

The objective of this study, carried out on behalf of Bordeaux Métropole, was to identify the best trade-off between exploitation and impact of the water resource located south of Bordeaux by combining a detailed analysis of field data with an optimisation approach using modelling (Marthe/Capucine).

Deforestation through agriculture and mining in French Guiana: impacts on mercury concentrations in water

This study increases our knowledge of the quantities of mercury and methylmercury (MMHg) in water and of suspended matter in different contexts of disturbance of the soils, in French Guiana.

Determination of anthropogenic pedo-geochemical backgrounds (FPGAs): the case of Toulouse Métropole

Urban soils hold the "memory" of cities; the geochemical quality of urban soils, to which the population is exposed, reflects its history: emissions since the industrial revolution, successive reconstructions on rubble, particularly following historical conflicts, etc. This is why we know little...

DYGEO: boosting support for geothermals to promote the use of this green energy

In 2018, ADEME and BRGM decided to focus on increasing the visibility of geothermal energy. First of all, this involves uniting the organisations that are promoting geothermal energy around an “advocacy campaign” for surface geothermal energy and then also of increasing the visibility of geothermal...
