Variabilité hydrologique et biologique du golfe du Lion. I. Transports en azote et productivité potentielle ArchiMer
Conan, P; Pujo-pay, M; Raimbault, P; Leveau, M.
A monthly time-series of the seasonal evolution of the North Mediterranean Current (NMC) and of nitrogen flux across a transect (5 degrees 12'5 E between 43 degrees 10'N and 42 degrees 50'N) at the entrance of the Gulf of Lions was carried out over two years. The NMC exhibited two distinct structures: a winter structure (from November to May) characterised by strong mesoscale and interannual variations in which the current was 20 to 30 km width, about 400 m depth and velocity scaled between 5 and more than 40 cm s(-1); and a summer structure (from May to November) which was less sensitive to mesoscale variations but showing large interannual variability. The current was located more offshore, was wider and shallower than the one in winter and velocity...

Réseau de Suivi Lagunaire Languedoc-Roussillon. Bilan des résultats 2008 et programme 2009 ArchiMer
Face à l’enjeu eutrophisation, le Réseau de Suivi Lagunaire (RSL) a été créé par la Région Languedoc-Roussillon, l’Agence de l’Eau Rhône-Méditerranée & Corse, l’Ifremer et le Cépralmar. Cet outil de suivi permet de diagnostiquer l’état des lagunes régionales vis-à-vis de l’eutrophisation et ainsi d’initier la mise en place d’actions et de mesures de gestion. Le suivi, commun à l'ensemble des lagunes de la région, permet de comparer annuellement l’état des lagunes. Il comprend : un diagnostic annuel de la colonne d’eau sur les mois d’été ; un diagnostic simplifié des macrophytes à un rythme pluriannuel (tous les 3 ans) ; un diagnostic complet de l’eutrophisation qui suit tous les 6 ans, en plus des deux compartiments précédents, l’état du...

Research activities in the Gulf of Lion (NW Mediterranean) within the 1997-2001 PNEC project ArchiMer
Raimbault, Patrick; Durrieu De Madron, Xavier.
The French national program on the coastal environment Programme National Environnement Cotier (PNEC) represented during the last decade a major support for the pluridisciplinary oceanographic research in the Gulf of Lion. During the second phase of the program, that lasted from 1997 to 2001, the main objective for this worksite was to establish an annual budget of carbon and associated biogenic elements to characterise the role of this region as source and the sink of elements. This introductory paper provides an over-view of the research framework and recapitulates the major scientific outcomes.

Variabilité hydrologique et biologique du golfe du Lion. II. Productivité sur le bord interne du courant ArchiMer
Conan, P; Pujo-pay, M; Raimbault, P; Leveau, M.
An estimation of the annual productivity in the Gulf of Lions has been made in the 0-100 m layer using a Let-Go system, with monthly measurements at a fixed station. A value of 140 to 150 g m(-2) a(-1) of C is found, of which around 75 % occurs in the upper 50 m. The seasonal production is described according to three distinct patterns during the two hydrological seasons: (1) variable production in winter; (2) surface bloom in late winter; (3) homogeneous and mean production in summer with a clear Deep Chlorophyll Maximum. The hydrological winter phase represented 60 % of total annual production. The seasonal duality of the hydrodynamic system and the mesoscale variations of the Northern Mediterranean Current account for the variability and the evolution...
