TL;DR: Four French research institutes were mandated to produce a critical scientific analysis on the latest knowledge of the causes, mechanisms, consequences and predictability of eutrophication phenomena and the methodology and the main findings are provided.

TL;DR: In this article, an ecosystem model based on nitrogen cycling and oxygen has been developed for the Thau lagoon, a semi-confined system with watershed inputs and oyster farming.

TL;DR: This situation was likely to favour nitrification, which led during autumn to higher nitrate concentrations within shellfish farming zones than outside, and filter feeders were able to alter the dominant biogeochemical process in the water column by stimulating nitrifica- tion.

TL;DR: The seasonal patterns of nitrification, denitrification and dissimilatory ammonium production (DAP) rates were studied in the sediment of 2 stations in the Thau lagoon (south of France) as discussed by the authors.

TL;DR: Picoeukaryotes, which numerically dominate the picoplankton community, are an important source of organic carbon for the protistan community and contribute to the carbon flow to higher trophic levels.
