A Lagrangian numerical investigation of the origins and fates of the salinity maximum water in the Atlantic ArchiMer
Blanke, Bruno; Arhan, Michel; Lazar, A; Prevost, Gwenaelle.
The origins and fates of the Atlantic salinity maximum water (SMW), formed through excess evaporation in the tropics and subtropics of both hemispheres, are studied using monthly mean outputs of a numerical simulation of the world ocean climatological circulation. After defining formation domains from the surface salinity field and the vertical stratification, a Lagrangian technique is used to estimate the formation rates and main pathways in each hemisphere and the role of this water in the framework of the warm water return flow of the meridional overturning cell. Formation rates around 9 and 11 Sv are found in the Southern and Northern Hemispheres, respectively. While the export of the southern SMW from its formation area is realized by the western...

Bilan de l'état des stocks et des mesures de gestion de l'espadon (xiphias gladius) dans les océans Atlantique, pacifique et indien et en mer Méditerranée ArchiMer
Le Couls, Sarah; Bourjea, Jerome.
Cette synthèse bibliographique présente les différentes commissions internationales de gestion des grands pélagiques dans les océans Indien, Atlantique et Pacifique, respectivement la CTOI, la CICTA et l'IATTC/WCPFC. De plus, cette synthèse focalise sur le cas de l'espadon Xiphias gladius et détaille pour chaque stock, les captures, l'état du stock ainsi que les mesures de gestion passées et en cours. Le stock de la Méditerranée est l'unique stock en état de surexploitation avéré et fait l'objet de mesures de gestion (interdiction des filets dérivants, fermeture saisonnière de la pêche) mais pas de TAC. Les stocks de l'Atlantique Nord, du Pacifique Sud-est, et de l'Océan Indien sont proches de la pleine exploitation voir en pleine exploitation. Parmi ces...

Distribution et taxonomie des Howella (Perciformes, percichthyidae) de l'Atlantique ArchiMer
Post, A.
On the basis of geographical distribution and morphological analysis of the Atlantic Howella , two subspecies of H. brodiei have been established, H. brodiei brodiei for the IndoPacific and H. brodiei atlanlica for the tropical and boreal Atlantic. H. sherborni has been recognized as a separate species, probably distributed circumglobally in southern Ocean but presently recorded only from the South Atlantic, the central South Pacific and from off southern and south-eastern Australia respectively. H. b. atlanlica and H. b. brodiei are distinct by having 3 scale rows between the lateral line and the origin of the second dorsal fin, while H. sherborni has 4 scale rows there. H. sherborni is in geographical contact with the two subspecies while H. b. brodiei...

Fragilidium duplocampanaeforme sp nov (Dinophyceae): A new phagotrophic dinoflagellate from the French Atlantic coast ArchiMer
Nezan, Elisabeth; Chomerat, Nicolas.
A new species of the genus Fragilidium, F. duplocampanaeforme sp. nov., is described from examinations by LM and SEM. This species has been recorded in summer on the French Atlantic coast, over a number of years. It was never abundant in the plankton and was very often associated with Fragilidium subglobosum, Pyrophacus horologium and also with toxigenic species of the genera Alexandrium and Dinophysis. Phagotrophy of F. duplocampanaeforme on Dinophysis prey is shown, and sexual reproduction is suggested by the observation of gamete-like small forms. The size and the peculiar shape of its cells do not correspond to any known taxon, but the plate arrangement fits the genus Fragilidium. The plate formula is Po, Pc, 4', 8 '', 10c, 6s?, 7"', 2 '''', lp. A...

Interaction between marine populations and fishing activities: temporal patterns of landings of La Rochelle trawlers in the Bay of Biscay ArchiMer
Poulard, Jean-charles; Leaute, Jean-pierre.
Marine populations are distributed heterogeneously in space and time because of the diversity of habitats and the requirements of species life cycles. Human exploitation of these resources also varies as a function of space, time and the type of fishing activities performed. These three factors determine fishing strategy at different levels of integration. The purpose of this study was to describe and analyse, with respect to different time scales, the relations between the modalities of resource exploitation and the biological or demographic characteristics of the species involved. These investigations relate to the more general task of acquiring the basic knowledge needed for spatialised management of fishing effort. A fleet of trawlers from La Rochelle,...

Mitochondrial Genetic Characterization Of Bluefin Tuna (Thunnus Thynnus) From Three Mediterranean (Libya, Malta, Tunisia); And One Atlantic Locations (Gulf Of Cadiz). OceanDocs
Farrugia, A.F.; Pla, C.; Viñas, J.; Tawil, M.Y.; Hattour, A.; de la Serna, J.M..
None of the previous genetic analysis found significant differences within the Mediterranean. However, a more exhaustive analysis is needed inside this sea. In this sense, we have analyzed the mitochondrial control region sequence variability of three Mediterranean locations: Libya (n = 22), Tunisia (n = 23) and Malta (n = 12). Additionally a sample from the Gulf of Cadiz (n = 24) in the East Atlantic Ocean was also included in the study. The AMOVA analysis revealed slightly (Fst = 0.013) but significative genetic differences (P < 0.000) for the Malta location, probably due to its small sample size (n = 12). In the other hand, when this location is removed from the analysis, no differences where found among the three remaining location (Fst = 0,005; P =...

Seasonal Mixed Layer Heat Balance of the Southwestern Tropical Indian Ocean ArchiMer
Foltz, Gregory R.; Vialard, Jerome; Kumar, B. Praveen; Mcphaden, Michael J..
Sea surface temperature (SST) in the southwestern tropical Indian Ocean exerts a significant influence on global climate through its influence on the Indian summer monsoon and Northern Hemisphere atmospheric circulation. In this study, measurements from a long-term moored buoy are used in conjunction with satellite, in situ, and atmospheric reanalysis datasets to analyze the seasonal mixed layer heat balance in the thermocline ridge region of the southwestern tropical Indian Ocean. This region is characterized by a shallow mean thermocline (90 m, as measured by the 20 degrees C isotherm) and pronounced seasonal cycles of Ekman pumping and SST (seasonal ranges of -0.1 to 0.6 m day(-1) and 26 degrees-29.5 degrees C, respectively). It is found that surface...

Synthèse de l'activité des navires de pêche en 2003 ArchiMer
Leblond, Emilie; Merrien, Claude; Berthou, Patrick; Demaneche, Sebastien.
This programme aims to respond to the public service mission of IFREMER, which is "to know, evaluate and develop the oceans' resources and enable their sustainable use". It thus brings together projects that have ambitions specific to each. The "Halieutic Information System" (SIH) has as its goal to build the observation network of halieutic resources and associated uses. It is mainly in charge of developing indicators about fishing flotillas and their output in the form of summaries to the various actors in the fishing industry (from research to professionals and managers) and the general public. This type of output is created thanks to the implementation of a standard methodology of monitoring the activities of ships, and to the existence since 2001 of a...

Total mercury in the water column near the shelf edge of the European continental margin ArchiMer
Cossa, Daniel; Cotte Krief, Marie-hélène; Mason, Robert P.; Bretaudeau-sanjuan, Jane.
The purpose of this paper is to investigate the distribution and the relative importance of processes that affect mercury distribution in the water column at the shelf edge of the Celtic Sea, on the western European continental margin. The water column, down to 4500 m, was sampled during two cruises, one in winter 1994 and the other in June 1995, on eight stations. Total mercury concentrations ranged from 0.29 to 9.37 pM with the extreme values in the first 200 m. The highly variable concentrations in the surface layers are attributed to intense atmospheric-sea water exchange processes. The low concentrations encountered in the shelf water prelude any significant influence of continental waters in this area. In the mixed layer, biological uptake and...

Динамика характеристик поля биолюминесценции и планктона в восточной Атлантике в зимний период IBSS Repository
Токарев, Ю. Н.; Битюков, Э. П.; Василенко, В. И.; Вильямс, Р.; Слипецкий, Д. Я.; Соколов, Б. Г..
Исследовано влияние гидрологических параметров водных масс, видового состава и обилия планктона на пространственную изменчивость амплитудных характеристик поля биолюминесценции вдоль 200 з.д. в Атлантическом океане. Показано, что вертикальное распределение интенсивности поля биолюминесценции коррелирует с количественным развитием фито- и зоопланктона, распределение которых обусловлено концентрацией биогенных элементов и вертикальной структурированностью основных гидрофизических характеристик. Предложено использовать результаты анализа пространственной структуры и амплитудно-временной изменчивости биолюминесценции в различных климатических зонах восточной части Атлантического океана для визуализации вертикальной структуры планктонного сообщества и...
