Recent Publication: Variability of the Red River Plume in the Gulf of Tonkin as Revealed by Numerical Modeling and Clustering Analysis

Vietnamese and French researchers from LEGOS, LOG and VAST investigated the daily to interannual variability of the Red River plume in the Gulf of Tonkin using 6-year (2011-2016) high-resolution numerical simulations. Their results show that the temporal evolution of the plume surface coverage is correlated with runoff (with a lag), but that runoff alone cannot explain the variability of the river plume; other processes, such as winds and tides, are involved.
These results are published in Frontiers in Marine Science:

A digital twin of the Nokoué Lagoon to anticipate floodings and pollutions

Located in Benin, West Africa, Nokoué Lagoon is a vast shallow water body (~150 km²), fed by saltwater from the Atlantic Ocean and freshwater from the Ouémé and Sô watersheds (Figure 2). In addition to its natural variability, the lagoon is subjected to considerable anthropogenic pressure, primarily due to pollutant discharges from lakeside villages lacking […]

Second ILICO Integration workshop on marine heat waves

Since 2022, a succession of marine heat waves have been observed along the metropolitan french coasts. These have had devastating consequences for marine ecosystems (species distribution, mass migrations, high mortality) and major socio-economic repercussions (fishing, aquaculture, tourism). The Integration group, formed in 2023 and made up of researchers, lecturers/researchers and managers, brings together different areas […]
