Located close to Balagu\u00e9 village at 10 km West from Saint-Girons, the Baget catchment (13.25 km2) is drained by a karstic network which supplied the surface runoff of Lachein stream (specific discharge: 36 l.s-1.km-2). It is a tributary of the Lez which joins the Salat River, right tributary of the Garonne River.\r\n\r\nFrom 1968, this experimental site was intensively equipped by the CNRS underground Laboratory of Moulis (today SETE). The device is composed of one main weir at the outlet, 3 full excess controls, 3 piezometers of which one inside the abyss, and one subterranean loss.\r\n\r\nThis karstic watershed has been surveyed since 1968 for some hydro-climatic parameters, particularly air temperature, precipitations and stream discharge at the outlet. Some geochemical parameters (pCO2, chemical and isotopic compositions of waters) and some hydro-biological and ecological data (invertebrates, particularly Crustacea) have been surveyed for periods during the last 40 years by the CNRS underground Laboratory of Moulis.\r\n\r\nSince 2011, Baget catchment belongs to the French Network of Catchments (RBV) and it is included in the certified National Observatory Service SNO Karst. Then, new parameters are measured twice a month or with higher frequencies during some flood events (major cations and anions, alkalinity, pH, conductivity, dissolved organic carbon, total suspended matter, H, O, C isotopes\u2026). Since 2014, a multi-parameter probe has been installed with different sensors to measure continuously water level, pH, conductivity, turbidity, dissolved oxygen, nitrate and chloride. These continuous measurements are calibrated twice a month with laboratory analyses. The water discharge is measured by BRGM-Occitania because the Baget karst is part of the French patrimonial network of ground-waters and it belongs to the piezometric network managed by BRGM.\r\n\r\nThe Baget catchment is very sensitive to limit conditions of surface drainage and to land covers. It offers the possibility to develop an eco-systemic survey, which integrates the hydrology, the geochemistry and the ecology of a mountain ecosystem in the SW of France. In this region, climate and land use changes will have significant impacts on biodiversity, ecosystem functioning and biogeochemical cycles for the next decades\r\n\r\nThe Baget catchment is  an international field site of the Critical Zone Exploration Network CZEN (http:\/\/www.czen.org\/content\/aurade-experimental-catchment) and it is one of the sites of the French SNO-KARST (Service National d\u0027Observation) labellised by INSU-CNRS. It belongs to the French Research Infrastructure OZCAR and it is also a  site of the French LTSER ZA PYGAR \u0022Zone Atelier Pyr\u00e9n\u00e9es-Garonne\u0022.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":1968,"yearClosed":null,"relatedSites":[{"typeOfRelationship":{"label":"belongs
