Digitized inventory of the French peatlands of 1949
Digitized data from the French peatland inventory ("Les tourbières françaises", Ministry of Industry and Trade, 1949). This national inventory was carried out in order to estimate the stock of peat in metropolitan France and to facilitate its exploitation, essentially for fuel purposes. Thus, a ...
Glaciological data Austre Lovén Svalbard
These data are measured in High Arctic over an observatory basin, located at 79°N on the W coast of Svalbard. Austre Lovén is a small 4.5 km² polythermal glacier in constant decline since the end of the LIA. The surrounding catchment is no more than 10 km² and exhibits a significant periglacial area ...

Pollen analysis - Vatteville-la-Rue (F-76), Mare de la Pelouse, Forêt de Brotonne
Eight pollen tests carried out on a borehole about one metre deep from a peat bog in the Brotonne forest. Samples very rich in pollen and spores. Last two millennia (Middle Ages?).
Physicochemical characteristics of water and sediment - floodplains of the Ain, Doubs and Loue Rivers - 2015-2016
19 sites (16 wetlands and 3 rivers) with different physicochemical characteristics and distributed along three rivers (Ain, Doubs, and Loue) were sampled. The physicochemical characteristics of the wetlands were measured in situ or after laboratory analysis.
Physicochemical characteristics of water and sediment - Ain River floodplain - 2019-2020
34 sites (16 wetland sites, 15 river sites, and 3 groundwaters) distributed along the Ain River with different physicochemical characteristics were sampled. The physicochemical characteristics of the wetlands were measured in situ or after laboratory analysis.
Monitoring of the vegetation of extensive mountain hay meadows in eastern France (Jura and Vosges)
Diachronic observations of the plant communities of extensive hay meadows in the Jura and the Vosges mountains. The data include 66 old floristic relevés (realized between 2005 and 2009), 66 recent floristic relevés (realized in 2019) and plant community descriptors.
Water vole and plant diversity in a productive hay meadow of the Doubs department
Data of 32 vegetation plots located in a productive hay meadow disturbed by water voles. It includes the plant species lists and the associated community descriptors.
Stone crushing and plant community diversity in dry calcareous grasslands (old Franche-Comté region, eastern France)
30 floristic relevés realized in 2019 in dry calcareous grassland sites (in areas disturbed by stone crushing and non-disturbed areas) as well as the description of the studied dry calcareous grasslands.
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
SISMEAUCLIM
This project is based on three disciplines: seismology, hydrogeology and climatology. It aims to develop a new approach to monitor hydrogeological reservoirs, in particular karst aquifers, subject to extreme climatic events. The objective is to carry out 4D imaging during floods in a watershed ...
FIBROKARST
This project focuses on understanding karstic systems and particularly on the issue of recharge and transfer processes in these very heterogeneous and generally inaccessible environments. The objective is to use the fiber optic technique to identify the recharge points of the karstic aquifer of ...
Pollen analysis - Vaux-lès-Saint-Claude (F-39), Eau Morte
Pollen tests in the filling of a circular depression (ice rest, pockmark?) in the heart of a meander of the Bienne. Two samples: 162 and 200 cm deep.
Sulfur isotope of sedimentary Barites
Multiple sulfur isotope measurements (d34S, d33S, d36S) of sedimentary barites associated with the Permo-Triassic boundary.
