MEDUSA: Marine benthic Ecological Data from Underwater imagery Surveys of sub-Antarctic Crozet environments
Inscribed on the UNESCO World Heritage list, the sub-Antarctic Crozet archipelago is located in a region facing significant environmental changes impacting a poorly known marine biodiversity. Underwater imagery constitutes a valuable non-invasive approach for gathering ecological data and improving ...
PROTEKER: a near-shore submarine observatory in the Kerguelen Islands for the long-term monitoring of benthic habitats
PROTEKER is a pilot program that aims at establishing a baseline for assessing the impact of climate change on near-shore marine ecosystems of the Kerguelen Islands by implementing an ecological and genetic monitoring at reference sites. The high diversity of coastal marine ecosystems is usually ...
EBSD mapping of shear zones strain gradient - deformation mechanisms
Objective : characterize the deformation mechanisms and the crystallographic fabrics within homogeneously deformed granitic samples.
EBSD mapping of brittle shear zones precursors
Objective : microtextural characterization within a shear zone brittle precursor
EBSD mapping of shear zones strain gradient - seismic anisotropy
Objective : calculate the crystallographic preferred orientation (CPO) of each mineral phase in order to rebuild the elastic properties of the polyminéralic aggregates.
Microprobe analysis on a brittle shear zone precursor
Objective : compare the chemical compositions of minerals within the brittle precursor and in the host rock.
Quantitative X-ray mapping of brittle shear zones precursors
Objective : characterize the chemical zonings in plagioclase and garnet related to fluid-rock interactions within a shear zone precursor
