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 ...
This describes the temperature data acquired in a range of piezometers throughout the Forbonnet peatland (Jura Mountains, Frasne-Bouverans peatland complex).
Strontium isotopic (87Sr/86Sr) ratio of waters samples from the Forbonnet peatland (Frasne-Bouverans peatland complex). 53 sampled represent low and high flow conditions and also a wide spatial cover through horizontal and vertical sampling across the peatland. One sample represent the upstream ...
Majors, traces elements and 87Sr/86Sr ratio of Cretaceous limestone (Hauterivien) and Quaternary marls (two samples). The limestone was sampled in the Frasne-Bouverans syncline at proximity of the Forbonnet pealtand (Complexe tourbeux de Frasne-Bouverans). The marl was sampled in the underlying ...
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 ...
Natural site: peat bog near the lake's outlet. 16 palynological samples. The selection was made in several drillings. Two pollen tests performed in 2021 towards the lake outlet.
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.
Ecological modelling is nowadays widely used to highlight the environmental conditions that influence the species ecological niche and better understand their response to environmental changes. Methodological challenges are however present for Southern Ocean marine case studies and it is important ...
Natural site over the alignment of the A39 motorway; drilling. Two series: T1 (18 poor samples) and T2 (88 palynological samples + 2 radiocarbon datings). Samples often difficult to read. Publication CRAS, 1996.
Hydrogeochemical monitoring of karst springs in the Jura mountains
Natural site: drilling with motorised "russian" core. 120 palynological samples. + 6 radiocarbon datings. 2015 publication: only the "gallo-roman" part.
Archaeological site: rock shelter. 10 palynological samples. Only one acceptable result. Archaeological excavation: Ch. Cupillard, SRA de Franche-Comté.
Archaeological site. Lake dwelling. 9 palynological samples (related to M. Magny PhD thesis, 1991).
Archaeological site. Lake dwelling. 11 palynological samples.
Archaeological excavation of rural settlement. 7 palynological samples. Approximate geographical coordinates.
Natural site: wooded swamp. 144 palynological samples with 2 radiocarbon datings. Sometimes quite poor. Further analyses were done in the village of Grozon around the salt springs by E. Gauthier (PhD, 2001).
Archaeological site. Lake dwelling. 14 palynological samples + radiocarbon and dendrochronological datings.
Peat bog; 51 palynological samples. Other analyses on this site by Carole Bégeot and Pascale Ruffaldi (2006)
The archaeological surveys carried out on the Le Locle bypass road have made it possible to make several test borring in the upper part of the fill of the area located south of the city, between the city and the Col des Roches, in the Marais des Calame and Marais de la Molière. Two sections were ...
Two boreholes (CID I of 5.77 m and CID II of 7.63 m) were drilled off the Domaine de Chalain (east bank), 65-70 m from the shore. 57 pollen samples were taken from CID I and 21 from CID II + 5 radiocarbon dates.
The set of climate projections available corresponds to the GCM (Global Circulation Model) data from CMIP5 (Coupled Model Intercomparison Project; Taylor et al., 2012) used in the fifth IPCC report. A total of 23 GCMs from 16 different institutions were downloaded on the ESGF (Earth System Grid ...
Only one sample in a natural depression in the heart of the castle excavation.
Peat bog. 9 palynological samples. KTH testing (see : Sjörgen, P. 2007. Mires and Peat, International Mire Conservation Group and International Peat Society ; Gobet, 2014)
Natural site: drilling. 71 palynological samples + 4 radiocarbon datings (one is wrong, too recent). Malacological studies by Nicole Limondin (1997).
Natural site: section. 44 palynological samples. Sterile or unavailable samples.
