| Coastal environments such as the Charentais Sounds are key systems in the biogeochemical cycles coupling (C, N, P) between the land, the ocean and the atmosphere. Within the coastal zone, salt marshes are considered as CO2 sinks associated to their significant autotrophic metabolism and sediment carbon (C) storage. However, this ecological functioning is more and more threatened by global change (acidification, sea level rise, eutrophication) and anthropogenic pressures decreasing blue C area potential worldwide. C dynamics over salt marshes are complex since various processes and fluxes take place at the different terrestrial-aquatic-atmospheric exchange interfaces at the spatio-temporal scales of the coastal zone. The ANR-PAMPAS research project allows... |
