| Les éléments nutritifs (N-NH4 +, N-N02-, N-NO3, P-PO4 3- et Si-Si(OH) 4) et la matière organique dissoute (COD, NOD, POD, urée, amines primaires libres) mesures en septembre 1984 en Méditerranee nord-occidentale sont interprétés en fonction de l'hydrologie. Les résurgences d'eaux subsuperficielles influencent plus les concentrations des éléments nutritifs que celles de la matière organique. La composition globale (en C, N et P) de la matière organique a pu être donnée : on note des différences entre les masses d'eau. |

| In order to be able to count the cases of coastal eutrophication and to propose methods to monitor as well as to reduce these phenomena, first of all it is necessary to precisely define the word eutrophication itself. Instead of the strict etymological definition, that is to say a progression of the enrichment of a medium, we will rather retain the concept of a state enriched at a point such as it causes harmful effects on the ecosystem, and nuisances to man's activities. Based on the average chemical equations of the organic matter synthesis/degradation in the sea, this operational definition thus puts forwards the harmful consequences of enrichment, i.e. the production of an excessive algal biomass, sometimes unbalanced from the point of view of... |

| On the framework of the agreement between the French and Indonesian Governments a Cooperative Joint Research program on the chronic pollution on the beaches in the form of stranded tar balls has been carried out by CNEXO and LEMIGAS teams. A second field survey was conducted in May 1984 in continuation of a reconnaissance survey carried out in August 1982. [1] This report is to give a picture, after the North Western monsoon period, of the tar accumulation on the four Indonesian test sites surveyed in 1982.The locations to be surveyed are beaches of islands in Kepulauan Seribu (Java Sea), Kepulauan Riau (Malacca Straits) as well as beaches of the Southern coast of Central Java (Krakal and Kukup near Jogyakarta) and Sulawesi (Langga). |

| La salubrité des produits livrés au consommateur est un des objectifs des programmes de surveillance de la qualité du milieu marin. Trois types de contaminants peuvent altérer la qualité des produits : les micro-organismes pathogènes, les micro-polluants chimiques et les biotoxines sécrétées par certaines espèces phytoplanctoniques. Une surveillance de la salubrité des mollusques bivalves susceptibles d'être affectés par ces trois types de contamination est assurée au plan national dans le cadre du Réseau Microbiologique (REMI), du Réseau National d'Observation de la qualité du milieu marin (RNO) et du Réseau Phytoplanctonique (REPHY). |
