OMIV - Time series of electrical resistivity data recorded on landslides

Dataset
Collected date : from 1 May 2011 ongoing
Labels : SNO OMIV
Creators : OMIV

Time series of electrical resistivity data acquired on OMIV landslides at a daily or sub-daily frequency depending on the sites and observation periods. The data are acquired at the surface through electrical panels or at depths in boreholes. For the electrical panels, the resistivity data are ...

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 ...

Reconciling late faulting over the whole Alpine belt: from structural analysis to geochronological constrains

The significance of late-stage fracturing in the European Alps in a large geodynamic context is reappraised by studying brittle deformations over the entire belt. In the internal Western Alps, paleostress datasets display a major occurrence of orogen-parallel extension resulting in normal faulting ...

ISLSCP II Atmospheric Carbon Dioxide Consumption by Continental Erosion

Estimates for the riverine export of carbon and of sediments: dissolved organic carbon (DOC) export, particulate organic carbon (POC) export, bicarbonate export, export of bicarbonate being of atmospheric origin (atmospheric CO2 consumption by rock weathering), and sediment export. Estimates are ...
