CO2 evasion along streams driven by groundwater inputs and geomorphic controls

Headwaters are hotspots of carbon dioxide (CO2) evasion from rivers. While emerging evidence suggests that groundwater contributes disproportionately to CO2 in headwater streams, the processes of CO2 delivery to streams and subsequent evasion to the atmosphere remain largely unknown. This study, partly based on CO2 measurements along the Houay Pano stream in Northern Laos (M-TROPICS/MSEC), […]

Field visit of the south-east Asian critical zone observatories

Norbert Silvera (IRD-iEES Paris) and Laurie Boithias (CNAP-GET) visited the 3 catchments in Laos, Thailand and Vietnam to meet local colleagues and students, and to collect monitoring data and samples. In Houay Pano (Laos) together with Olivier Ribolzi (IRD-GET), Anne Pando (IRD-iEES Paris) and Bounsamai Soulileuth (IRD-iEES Paris) they evaluated the extent of the landslides […]

Reservoir methane release in Northern Thailand

From 26 October to 2 November 2018, in situ measurements of dissolved methane concentrations were carried out in the water column of the Maethang irrigation reservoir by three scientists from the iEES Paris joint research unit (Sylvain Huon, Véronique Vaury, and Jean-Louis Janeau). Water and gas samples were also collected to perform stable carbon isotope […]

PhD defence of Le Thi Huong : Impacts of landuse change on stream microbial communities in tropical catchments

Today October 17, 2018, Huong Thi LE successfully defended her thesis on the impacts of landuse change on stream microbial communities in rural, tropical catchments. Huong’s field work was performed within two M-TROPICS catchments: Houay Pano in Laos and Dong Cao in Vietnam. Her research was supervised by Thomas POMMIER (Ecologie Microbienne Lyon) and Emma […]
