Hydrodynamic and Anthropogenic Influences on PHytoplankton and bacteriOplankton of the Bach DaNG Estuary
Because of the economic and ecological interest that the zone of Haiphong in Vietnam represents, the potential importance of the anthropogenic contributions (nutrients, contaminants, particles), and the existence of a pole of research and higher education on the area, we are undergoing a multi-disciplinary study of the impact of anthropogenic and hydrological constraints on the functioning of this coastal estuarine ecosystem. The focus is on the role of trophic networks, in particular microbial, as it is known that the micro-organisms can actively control the fate and impact of anthropogenic inputs.
The central objective of this study is to determine the sources, transport mechanisms and processes of transformation of the elements of anthropogenic origin, and then to compare their effects on the diversity and functioning of the micro-organisms within the Bach Dang estuary. Our goal is to describe and predict the fate of these elements (integration in the trophic networks, sequestration in the sediments, and/or export to the coastal ecosystem) in order to lead in the long term to an integrated management of the zone in relation to the local actors of research and decision makers.
The HAIPHONG project (2008-2010) is funded by EC2CO French National Program. It also received the support of the Groupement de Recherche "Réseaux Trophiques Aquatiques" CNRS-GDR 2476.
