Nutrient loading by riverine input into estuarine systems has increased by 6–50 times for the
N load from pristine conditions to present, whereas a 18–180 times increase has been …

Primary production, nutrient concentrations, phytoplankton biomass (incl. chlorophylla) and
water transparency (Secchi depth), are important indicators of eutrophication. Earlier basin …

Trends in nitrogen utilization, determined with 15 N-labeled substrates, were related to
blooms of distinct phytoplankton groups in the Gulf of Riga, Baltic Sea, during May, June and …

The Mar Menor is a coastal lagoon increasingly threatened by urban and agricultural
pressures. The main watercourse draining into the lagoon is the Rambla del Albujón. A …

A box model has been implemented to understand the large-scale biogeochemical cycles of
nitrogen, phosphorus, and silicon in the Gulf of Riga. The large data sets collected within the …

In this study we follow seasonal changes in the phytoplankton community composition in a
shallow, mostly freshwater lagoon of the Baltic Sea. Nutrient enrichment effects on the …

Occurrence, composition and biolability of total dissolved nitrogen (TDN, including dissolved
inorganic and organic N ([DIN and DON]) were examined in May and July 1996 in the …

Previous trend studies have shown increasing nitrogen and phosphorus as well as
decreasing silica concentrations in the water mass of the Baltic Sea. This has had an impact …

Concentrations and rates of uptake of dissolved organic nitrogen (DON, free amino acids,
and urea) and inorganic nitrogen (DIN, nitrate, and ammonium) were measured along two …

Pour pouvoir recenser les cas d'eutrophisation côtière et proposer des méthodes tant de
surveillance que de réduction de ces phénomènes, il convient tout d'abord de bien définir le …
