The second TROPECOS field work in mangroves of Rio de Janeiro (Mamangua and Itacoatiara) 24 May 2025 – 7 June 2026, involved 14 TROPECOS research scientists and students from BOREA, LPG, UFF and UFPA. We measured gas fluxes in mangrove soils and waters, dissolved carbon concentrations and water current in tidal creeks, and high resolution dissolved redox species in sediments using 2D gels.
The second TROPECOS field work in Mékong Delta, 19-26 March, 2025, involved 3 research scientists, one post doc and one master student from IGE, CARE/HCMUT and CARRTEL. The four main branches of Mékong Delta were sampled along about 500 km in order to cover the entire salinity gradient from freshwaters to seawaters along the coast. This second campaign was realised in dry season and will allow to compare different land use in the different branches (paddy rice, aquaculture, urban area…)
The second TROPECOS field work in mangroves of Pará (Marapanim and Salinas) 6 May 2025 - 28 May 2025, involved 11 TROPECOS research scientists and students from BOREA, LPG, UFF and UFPA. We measured gas fluxes in mangrove soils and waters, dissolved carbon concentrations and water current in tidal creeks, and high resolution dissolved redox species in sediments using 2D gels.
Five TROPECOS researchers from IGE and CARE/HCMUT have joined the Antea, a scientific vessel from the French ocean fleet which sailed for 1 month along the Vietnamese South coast (10 June – 10 July 2024). During the field trip in wet season, intensive sampling of water for dissolved and particulate carbone as well as CO2 and CH4 concentrations was realised within the Saigon Dong Nai estuary, in two branches of Mékong Delta and along the coast.

This TROPECOS fieldwork in the mangroves of Ouvéa involved a team of six scientists, including a researcher, two PhD students, a post-doc, a researcher technician and an intern from University of New Caledonia.
The week-long mission was made possible through the agreement of the landowners from the Téouta tribe and the hospitality of the women’s association in the Téouta tribe (FAI DOHU association).
The first TROPECOS field work in mangroves of Pará (Marapanim and Salinas) 12 November, 2024 - 21 November, 2024, involved 13 TROPECOS research scientists and students from BOREA, LPG, UFF and UFPA
