Application de modèles dynamiques bayésiens aux séries temporelles de Dinophysis à Antifer (Normandie, France) ArchiMer
Soudant, Dominique.
Le Dinophysis est une microalgue toxique à l’origine d’epidémies diarrhéiques. En dépit de nombreuses études, l’écologie et la biologie de ce genre phytoplanctonique restent mal connues. Afin de déterminer les conditions d’apparition de Dinophysis cf. acuminata sur le site d’Antifer (Normandie, France), des prélèvements d’eau de mer ont été effectués quasi-journellement pendant les périodes estivales des années 1987 à 1993. Les séries temporelles résultantes concernent la concentration de la microalgue et les facteurs chimiques, physiques et météorologiques. L’analyse de ces données à l’aide d’outils sta- tistiques classiques (e.g. régression) s’est avérée difficile (e.g. instabilité temporelle des résultats). Une caractéristique commune de ces méthodes...

Apports de nutriments et développement phytoplanctonique en baie de Seine ArchiMer
Aminot, Alain; Guillaud, Jean-francois; Andrieux Loyer, Francoise; Kerouel, Roger; Cann, Philippe.
As part of the Programme National d'Oceanographie Cotiere, the nutrient dynamics of the Bay of Seine were studied between 1992 and 1994 in order to complement work on ecological modelling. Firstly, the River Seine's nutrient fluxes were established: 80 000-130 000 t a(-1) of dissolved inorganic nitrogen, 6 400-8 400 t a(-1) of dissolved phosphorus and 20 000-77 000 t a(-1) of dissolved silicium. Estuarine processes were taken into account. Consequences of nutrient loading for the bay were then evaluated at the pelagic level (nutrient and chlorophyll enrichments) and the benthic level (distribution of various phosphorus fractions in superficial sediments). The large continental inputs always induce concentration gradients in the water from the mouth of the...

Caractérisation et déterminisme du développement d'une population de l'annélide tubicole Lanice conchilega (Pallas, 1766) (Polychète Terebellidae) associé à la conchyliculture en Baie des Veys (Baie de Seine Occidentale) ArchiMer
Ropert, Michel.
Since the mid 80's, a tidal population of the polychaete Lanice conchilega has proliferated along the eastern part of the "Baie des Veys" (Western part of the Bay of Seine). Population density 7 000 individuals per square meter. This proliferation affected significantly the local oyster farming industry, by resulting increased sedimentation rates. This work try to improved understanding the phenomenon by analyzing at various temporal and spatial scales the ecosystem and its relationship with the Lanice conchilega population dynamics. Several field works were carried out (i.e. bottom type mapping, topography, hydrology) to analyse the occurrence and development of this population taking into account the overall changes of the "Baie des Veys" ecosystem....

Contamination chimique du milieu marin : de la mesure à l'évaluation des risques ArchiMer
Abarnou, Alain.
This activity report entitled (“Chemical contamination of the marine environment: from measurement to risk assessment”) summarizes the main stages my career at Ifremer from November 1975 to june 2013. The first chapter deals with the seawater chlorination and chlorinated waters released into the sea, the identification and the conditions of the formation of various by-product of these processes. The second chapter concerns PCBs, their nature, their chemical analysis in environmental matrices. PCBs are considered as the best examples of persistant and bioaccumulable compounds and therefore, in all this report they are flagship contaminants to which other groups of studied substances are compared. The third chapter refers to studies performed within marine...

Dynamique des matières en suspension en mer cotière : caractérisation, quantification et interactions sédiments/matière organique ArchiMer
Chapalain, Marion.
The knowledge of suspended particulate matter (SPM) and turbidity dynamics in coastal waters is essential for studying marine ecosystems. Flocculation/deflocculation processes are crucial mechanisms controlling the dynamics of SPM physical characteristics and thus, the fate of these SPM in the environment. This PhD thesis focuses on the SPM characteristics and their dynamics in coastal waters, from tidal to annual scales, in response to hydrodynamic, hydrological and biological forcing that take place at the interface between estuaries and coastal seas. To this end, optical and acoustic sensors were deployed in situ through 6 field campaigns in 2016, in order to characterize and quantify SPM in the water column, near the mouth of the Seine estuary...

Foucher, Eric.
The assessment of the King scallop stock of the Bay of Seine (Pecten maximus) was carried out in July 2019, in the Bay of Seine sensu stricto, located in French territorial waters (from the Normandy coast to the south to the limit of 12 nautical miles to the North), as well as the bordering zone lying north of this 12-mile limit and up to a latitude of 49°48N to the North, called "Extérieur Baie de Seine". For this, a scientific survey, based on a stratified random sampling plan, was conducted aboard the F/R Thalia, a coastal research vessel of the French Oceanographic Fleet. Nearly 170 sampling points were completed in the whole area. Analysis of these data leads to an overall increase in exploitable biomass over the entire area. Outside the Bay of Seine,...

Évolution pléistocène de la Seine fluviatile préservée en Baie de Seine ArchiMer
Benabdellouahed, Massinissa; Dugue, Olivier; Tessier, Bernadette; Thinon, Isabelle; Guennoc, Pol.
New high-resolution seismic data complemented with bedrock samples allowed us to propose a revised geological map of the Bay of Seine and to better define the control by the geological substrate on the morphogenesis and evolution of the Seine River during Pleistocene times. The new data confirm previous works. The Bay of Seine can be divided into two geological parts: a Mesozoic monocline domain occupying most of the bay and a syncline domain, mostly Tertiary, in the north, at the transition with the Central English Channel area. The highlighting of Eocene synsedimentary deformations, marked by sliding blocks in the syncline domain, is one of the most original inputs of this new study in the Bay of Seine that underlines the significant role of the...

La baie de Seine : hydrologie, nutriments, chlorophille (1978-1994) ArchiMer
Aminot, Alain; Guillaud, Jean-francois; Kerouel, Roger.
The data of hydrology, nutrients and chlorophyll obtained in the Bay of Seine over the period 1978-1994, from 14 océanographie cruises, are synthetised and illustrated by an atlas. The Bay is a typical example of a coastal area influenced by a large river. In winter, the nutrient input is drained off into the eastern Channel. In spring, nutrients are consumed intensively. Silicate is the first that drops to limiting levels. The spring bloom generally begins in the centre-east of the Bay. Chlorophyll a can reach up to 40-70 µg/l during the year, values typical of eutrophic coastal areas. Despite the regular increase of nitrogen inputs, the biomass (as chlorophyll) has not significantly changed over a fifteen year period.

Les campagnes d'évaluation du stock de coquilles Saint-Jacques en Manche orientale : méthodologie et estimation des indices d'abondance ArchiMer
Vigneau, Joel; Fifas, Spyros; Foucher, Eric.
The methodology used for obtaining absolute abundance indices for Eastern Channel scallop is described in this paper. For the survey (COMOR), stratified multi-stage random sampling is used. The number of sampled units is computed based on variance estimates from the last survey. Knowledge of gear (Brittany dredge with a diving plate) selectivity and efficiency parameters is required for estimating total exploitable biomass and absolute abundance indices by age and strata. Details of the mathematical development of all estimators are given. A non parametric bootstrap provides confidence intervals for all estimates.

Modélisation écologique tridimensionnelle (3D) de la baie de Seine (Manche, France) ArchiMer
Cugier, Philippe; Ménesguen, Alain; Guillaud, Jean-francois.
A three dimensional (3D) ecological model is developed and applied to the "baie de Seine" area. It consists of a 3D model for hydrodynamics and port (SiAM3D) coupled to an ecological model simulating nutrient cycles (nitrogen, phosphorus, silicon) and two phytoplanktonic classes (diatoms and flagellates). The model is validated by confronting simulations with nine year long series of measurements and then used to better understand the ecosystem functioning. It especially allows to show the role of the proportion of silicon with regard to nitrogen and phosphorus in the summer loadings of the Seine river on the more or less strong presence of flagellates in the river plume. The model was also used to test various hypotheses of reduction of nitrogen loading...

Modélisation sur vingt ans (1976-1995) de la production phytoplanctonique en baie de Seine ArchiMer
Guillaud, Jean-francois; Menesguen, Alain.
This paper presents an ecological modelling of the Bay of Seine (Eastern Channel) over the last twenty years, chosen as a typical case of eutrophication in a river plume. In the physical sub-model, the Bay is divided into 42 boxes and water fluxes between them are calculated automatically using Ifremer's "Elise" software. A two-layer, vertical thermohaline model is then linked with the horizontal circulation scheme in order to take vertical stratification into account. The biological submodel deals with two chemical elements, nitrogen and silicon, and splits phytoplankton into diatoms and flagellates. Results from this ecological model point out the spatial concordance of highest phytoplanktonic concentrations with the river plume spreading in the bay....

Phytoplancton en baie de Seine. Influence du panache fluvial sur la production primaire ArchiMer
Videau, Christiane; Ryckaert, Mireille; L' Helguen, Stéphane.
Phytoplankton distribution and primary productivity were investigated in the Bay of Seine (eastern English Channel, France) in spring and early summer of 1992 and 1994. In 1992, the horizontal distribution of phytoplankton species was determined over the whole Bay of Seine. In 1994, species distribution and primary productivity were studied along the salinity gradient of the Seine plume and in the neighbouring marine waters. Phytoplankton distribution was characterised by the permanent diatom dominance from early spring to early summer. The spring bloom did not occur uniformly over the bay, but was initiated in the marine waters, in the middle of the bay and progressed towards the coast where it developed, in June, in the diluted waters of the Seine plume....
