Les cinq articles qui suivent concernent, au moins en partie, le zooplancton marin dont l'étude bénéficie elle aussi des progrès de la biochimie marine, à la fois dans le domaine des techniques (application au zooplancton de méthodes de dosages biochimiques) et dans celui de la connaissance des mécanismes de fonctionnement de cet élément du réseau trophique pélagique. |

An analysis of the fishing power concepts leads to a distinction between local fishing power (at a given location). and overall fishing power. Overall fishing power takes into account the ability to detect and quickly exploit rich areas. In order to estimate local fishing power it is necessary to compare the catches of different ships operating in neighbouring areas. Such a comparison performed on two ships will give an estimate of their relative fishing powers. The closer the two ships are, the more reliable will be the estimate. A weighting function must be used, and this function is related to the spatial heterogeneity of the fish density. Such a function is provided by the variogram as defined by Matheron (1965).

From a study of first-transition series trace elements and low-partition-coefficient trace elements or so-called hygromagmatophyle elements (Treuil and Varet, 1973; Treuil and Joron, 1976), we will try to define the relative importance of the three fundamental parameters- mantle source composition, extent of partial melting, and crystal fractionation-which bear on the formation of basalts recovered during Leg 45.We relate the presented data to the results of shipboard study (Chapters 7 and 8, this volume) and then give a tentative interpretation, taking into account our present knowledge of the behavior of trace elements during magmatic processes of FAMOUS and Leg 37 results.

Le Gall, Jean. |
Fish smoking has always been done in the same way; its principle consists of exposing the fresh or slightly salted fish to the action of the smoke created by the slow combustion of wood sticks, chips or sawdust. Under the action of the heat, the fish dries and, at the same time, impregnates with the empyreumatic products of the smoke which colours it and gives it a savoury taste. [...] |

A schematic model of the evolution of the South Atlantic ocean is proposed to demonstrate the possibilities offered by the Deep Sea Drilling Project within the framework of Plate Tectonics to reconstruct a logical evolution of the history of the ocean basins and their paleoenvironment. The emphasis is put on the methodology available to reconstruct the ocean crust morphology and its sedimentary cover at all stages throughout the opening of the ocean.Paleobathymetric, deep paleo-water-circulation and paleo-sedimentary - facies maps at five different stages of the opening are presented and discussed. The last type of maps are in great part based on a new paleo - Carbonate Compensation Depth Curve for the South Atlantic which is tentatively proposed here.... |

Sea cucumbers of the Molpadonia order are average size animals, frequently found on deep muddy sea bottoms. The Molpadonia order, often reorganized by Clark (2), Heding (3), Deichman (4) and Pawson (5), currently consists of four families. Several abnormally small specimens, of a new genus, possibly belonging to the Molpadiidae, were collected with an epibenthic drag during the Polygas (October 1972) and Biogas 4 (February 1974) cruises at the following stations. |

Based on the study of some seismic-reflection profiles, we demonstrate that the identified sedimentary units show a structural anomaly at the bottom of the North-African continental margin compared to the situation observed on the other margins of the western Mediterranean basin: all the deep Messinian and infra-Messinian deposits are subjected to a flexure when reaching the North-African margin; the created depression is filled by the plio-quaternary deposits. This observation, set back in the geodynamic context of the western Mediterranean, leads to the following interpretation: the North-African margin is a very active margin at a very early evolutional stage. The abnormal structure of the gravity field in the considered region confirms this... |

We characterized the microfacies of sediments encountered dunng Leg 44 on the basis of coarse fraction mineralogy ( sup 125 m), silt mineralogy (63 inf inf 20 m), clay mineralogy ( inf 2 m), silt and clay particle size distributions, and calcium carbonate contents. Secondly we attempted to tentatively correlate microfacies changes with major oceanographic events which have affected the sedimentary processes along the continental margin of North America.Because part of the stratigraphic column was not recovered (no Pliocene and Oligocene, and reduced Pleistocene and Barremian sections), and because of the fairly large sampling intervals our results are far from complete and exhaustive.Some important results, however, concerning the evolution of the... |

The biologic and ecologic factors enabling the rearing of tuna species in the purpose of restocking oceans are presented. Such effort will require to carry out research on the following points which have been already investigated to some extend : - controled reproduction from mature fishes kept in captivity. - rearing of larva up tO the juvenil stage and mass production of their foods. - conditioning juveniles for rearing in natural environment. |

1. A quantitative and electrophoretic study of copper and zinc in hemolymph of the crustacea decapoda, Carcinus maenas, has been carried out. 2. Most of the copper was linked with hemocyanin.3. All copper-binding proteins are hemocyanin.4. Zinc belongs to three different compartments: more than 68% is linked with hemocyanin; about 10% is shown in the fraction containing blood cells, lipids and carotenoids; 15% is present in the hemolymph under a soluble and dialysable form. 5. Specific zinc-binding protein has not been found out in the serum of Carcinus maenas.6. Zinc linked with hemocyanin is found on high molecular weight protein fractions only. [NOT CONTROLLED OCR] |

En France, il n'existe pas un seul port sur l'Atlantique qui pratique la pêche industrielle du hareng qui semble réservée aux ports de la Manche : Boulogne. Fécamp et Dieppe. Pourtant les Lorientais pourraient, aussi bien que les Boulonnais, par exemple, exploiter certains lieux de pêche de ce clupéide : Small's ou Inishtrahul... Ils ne capturent pas le hareng, pas plus qu'ils ne recherchent le maquereau, au chalut : ils le fuient dans la mesure du possible. Pour les chalutiers bretons le hareng est nul et non avenu et ce clupe n'est guère connu dans cette contrée que sous la forme de "saur". En ce qui concerne le Morbihan qui nous intéresse, le hareng pourrait être capturé en quantités industrielles pendant la fin de l'automne et le début de l'hiver,... |

Research on the endocrine mechanisms controlling the reproduction processes in the shrimp Penaeus japonicus Bate lead to the study of the effect of some external factors impacting the internal clock on which these mechanisms are tuned, namely temperature and light. Full sexual maturity was obtained in 3 months in culture conditions. Over the three following months, 72 spawns of a total of 960 000 nauplii, obtained with a population of 60 females aged 1 to 2 years old at the beginning of spawning, were counted. |

Lithologic and stratigraphic evidence from D.S.D.P. Site 398 (3910 m water depth, 1740 m total penetration) and regional seismic reflexion data are placed in the context of the early tectonic evolution of the North Atlantic ocean. The morphology of the western Iberian continental margin is the result of two main tensional episodes dated Permo-Lias and Upper Jurassic - Lower Cretaceous, during which the initial basins between Grand Banks and Iberia were created by subsidence and tilting of continental blocks. A limited oceanic opening had probably occurred in Jurassic time between these two tensional episodes. There was no relative motion during Lower Cretaceous between North America and Iberia.

A vertical distribution of temperatures in the lithosphere allows us to generate a simple gravimetric model which closely matches the observed free-air anomaly across oceanic fracture zones. Topographic highs associated with fracture zones are not compensated in the active transform part but become progressively compensated in the fossil part. At distances corresponding to a period of 10 to 20 m.y., compensation is complete. [NOT CONTROLLED OCR] |
