| Readers of our first CHARM I atlas will know that almost everything contained within the atlas was original work resulting from two years of intensive study of the Dover Strait by a dedicated and inter- disciplinary team working from bases on either side of the Channel. The present atlas has carried on this eminent precedent, though this time covering the whole of the eastern English Channel (figure 1) and widening considerably the thematic scope. We believe that readers of this current atlas will be impressed by both the breadth and depth of the information provided, and that therefore this content should be available for use in both a wide variety of fields and at various levels of interest (researchers, industries, statutory organisations, the wider... |

| The North Sea Benthos Project 2000 was initiated as a follow-up to the 1986 ICES North Sea Benthos Survey with the major aim to identify changes in the macrofauna species distribution and community structure in the North Sea and their likely causes. The results showed that the large-scale spatial distribution of macrofauna communities in the North Sea hardly changed between 1986 and 2000, with the main divisions at the 50 m and 100 m depth contours. Water temperature and salinity as well as wave exposure, tidal stress and primary production were influential environmental factors on a large (North Sea-wide) spatial scale. The increase in abundance and regional changes in distribution of various species with a southern distribution in the North Sea in 2000... |

| INTRODUCTION: The Dover Strait (Figure 1) connects the North Sea to the English Channel. Here, northern France and South-East England are at their closest. This narrow corridor, one of the world's busiest straits for maritime shipping, is a key economic area for numerous activities, such as leisure and tourism, international ports and shipping, plus the exploitation of living or abiotic marine resources. This area is a significant resource for fisheries because many commercial fish species are abundant there, but also because of the presence of nursery and spawning areas and migratory routes linked to specific environmental characteristics. The vulnerability of these resources, which are subjected to strong anthropogenic pressures, has brought together... |

| Populations of Abra alba (Wood) (Mollusca : Bivalvia) were studied over a fifteen-years period at three sites: the southern part of the North Sea (Gravelines area), the Bay of Seine, and the Bay of Morlaix in the western English Channel. These surveys provide an example of long-term changes in a species considered as ''opportunistic'' and as a ''biological indicator'' of disturbance. A summed cumulated function was used to compare the changes of the Abra alba populations and of mean air temperature in each area. The graph of this function shows the timing and duration of changes. Four or five main periods were identified at each site, with a succession of periods of abundance, stability, and decrease. The abundance periods were separated by ten years in... |

| Cet ouvrage est le fruit d’une collaboration entre l’Agence de l’Eau Artois-Picardie et le Laboratoire d’Océanologie et de Géosciences de Wimereux (LOG). Il recense les espèces marines animales et végétales introduites sur la Côte d’Opale, en région Nord - Pas-de-Calais: le but de l'ouvrage est de présenter la liste la plus exhaustive possible des espèces marines introduites. Sont présentés la biologie, l'habitat, la date d'introduction parfois estimée ou la date de première signalisation, la répartition de l'espèce dans les mers avoisinantes ainsi que les problèmes environnementaux qu'elle pose éventuellement. |

| This study examines whether meso-scale meteorological events, in particular the alternation of cold and mild periods, influenced the structure of four Abi cr alba communities, sampled from 1977 to 1992 on the northwest French coast. We propose a new numerical procedure to describe temporal variations in the structure of each assemblage, using some niche-oriented models recently developed by Tokeshi (1993). The description of the temporal changes in the structure of each community was summarized into a 2D-plot of an ordination, performed on observed and simulated patterns. Results showed that important changes occurred in these four assemblages, which were not directly related to the meso-scale climatic events, but mainly to the local environmental factors... |

| This is the 33th annual surveillance report concerning the nuclear power plant of Gravelines. Its very high power level results from six plant units located on the shore and is characterised by a cooling system with a coastal surface input and output. The production of electricity began in 1980 and reached maximum in 1986. Surveys concern monitoring of pelagic system (hydrology, microbiology, phytoplankton, zooplankton), fish populations (larvae and eggs of Sole and Sprat) or crustaceans (shrimps), and benthic macrofauna (intertidal and subtidal). This survey deals with spatial and temporal approaches (i) study of the direct impact by comparison of the input and output seawater stations, (ii) study of medium and long term evolution of the area by... |

| La nouvelle stratégie mise en place au cours de la 9ème période de surveillance de Gravelines consiste à abandonner l'étude temporelle caractérisée par un grand nombre de campagnes pour privilégier les variations spatiales, pour trois situations annuelles printanière, estivale et automnale, afin de comparer l'ensemble des paramètres aux quatre stations entrée de centrale, rejet, point impacté à T = + 3°C et point de référence T = O°C (hors impact). Les domaines d'études sont: la climatologie, le fonctionnement de la centrale, l'hydrologie, la microbiologie, le plancton, l'halieutique, le benthos. Dans tous les domaines l'effort est mis sur les estimations de déficit de biomasses au rejet d'une part et les compétitions intréspécifiques quand le milieu... |

| Pendant la période Novembre 1987 - Octobre 1988, l'échauffement de l'eau dans le canal de rejet est équivalent à la période précédente (+ 8°C à + 8.5°C): Le taux de recyclage de l'eau calculé par rapport au bromoforme est de 4.3 %. Le bromoforme présente une valeur moyenne de 14 llg/1. La concentration moyenne annuelle de vibrions est 100 fois plus élevée au rejet qu'à la prise d'eau. La destruction de la biomasse chlorophyllienne due au transit est voisine de 50 % et celle de la biomasse zooplanctonique exprimée en carbone est d'environ 40 %. En 1988, les conditions météorologiques ont été favorables à la prolifération des Phaeocystis puis des noctiluques dans un milieu très eutrophisé. L'évolution des niveaux supérieurs de l'estran se confirme cette... |

| La stratégie d'étude modifiée en 1989 a pour but de cerner les impacts, par comparaison entre stations et choix d'espèces cibles. La puissance de fonctionnement de la centrale varie au cours de l'année de 4.5 à 6 tranches de 900 MW, le débit de refroidissement varie de 180 à 240 m3/sec. L' échauffement moyen du canal de rej et est de 8.9 0 C. L'eau recyclée es t estimée à 5.4 %. L'impact de transit se traduit par une multiplication intense des Vibrions, un déficit de biomasse chlorophyllienne (60 %), biomasse zooplanctonique (50 %), déficit dans l'abondance des oeufs (30 %) et larves (100 %) de soles. L'impact sur le milieu récepteur est visible dans le compartiment bactérien et sur les espèces benthiques. Le déficit en biomasse benthique subtidale du... |

| L'année 1992-1993 se distingue des périodes précédentes par un hiver peu rigoureux et, surtout, par un été humide et venteux. La quantité moyenne hebdomadaire d'électricité produite pour la période est de 618 MW.h, soit l'équivalent de quatre tranches, pour un débit moyen calculé de 204 m3/s, soit l'équivalent du débit de pompage de 5 tranches. Sur cette base de calcul, l'augmentation moyenne de la température de l'eau au rejet est de 8.65°C. Cette valeur est plus faible que celle de la période précédente 1991-1992 (9.44°C). Les dosages des haloformes et en particulier du plus abondant d'entre eux, le bromoforme, permettent de mesurer la conformité de la période de chloration à l'autorisation préfectorale, l'étendue du panache de rejet et le taux de... |
