    Publication Date: 2017-01-04
    Description: This article reviews the major findings of an intensive geological and geophysical study of the Brazilian margin and adjacent oceanic and continental areas. Most of the data fits well with standard plate models for Atlantic-type margins, with clearly recognizeable pre-rift, rift, proto-oceanic and oceanic stages. However there are significant problems regarding the nature of the crust beneath the margin and the position of the boundary between oceanic and continental crust.

    Publication Date: 2017-04-04
    Description: The following report is a synthesis of the main results of the OECD Cooperative Programme on Eutrophication. It is the outcome of several years' concerted effort by 18 Member countries. The objectives were to establish, through international cooperation, a basis for eutrophication control of inland waters (lakes and reservoirs in particular), and to develop better guidelines for fixing nutrient load criteria compatible with water use objectives. The present report is both complementary and supplementary to the four Regional Project Reports (2) already published. In parallel with the OECD study programme, progress has been made in other areas, particularly in dynamic modelling. The results of the OECD study and approach have already been successfully applied in several instances in North America, Europe and elsewhere. It can be anticipated that 0- while knowledge of eutrophication and its control methods are advancing -- the OECD results presented here will continue to provide a basic reference in eutrophication control studies.

    Description: The reproductive ecology of three sympatric hermit crab species from the Bay of Panama is examined. All three species reveal patterns of size and reproduction mediated by their supply of shells. Shells are demonstrated to be in limited supply. Crabs with shells large enough to allow growth, put effort into growth at the expense of reducing reproductive expenditures, while crabs in shells too small to permit growth allocate more time and effort into immediate reproductive gains. This resource regulated trade-off between growth and reproduction gives these tropical crabs plasticity in important life-history traits. Crabs with a relatively poor supply of shells reproduce at smaller sizes, reproduce more frequently, have larger clutches, and are unable to reach the larger sizes of crabs with a less limiting supply of shells. This flexibility in life-history traits allows these crabs to tailor their reproductive schedules to resource supplies controlled by gastropod mortality, as well as the presence of competitors and predators.

    Description: The interaction between thrust and strike slip fault systems is well detailed in Pakistan where the Chaman transform zone connects the Makran and Himalayan convergence zones and contains an internal convergence zone in the Zhob district. The transform zone contains numerous strike slip faults of which the Chaman fault proper is the westernmost. We can demonstrate at least 200 km of left lateral displacement along the Chaman fault alone. In the Zhob belt N-S shortening by folds and a major thrust fault amounts to several dozen kilometres. The 400 km wide Makran convergence zone is now being shortened by E-W oriented folds, thrust faults, and reverse faults. As these faults in the Makran zone approach the transform zone, their traces bend to the N and motion on each of them becomes oblique, combining reverse and left lateral slip. They merge continuously with the strike slip faults of the Chaman transform zone. The Makran thrust system and the Chaman transform zone first became active in the late Oligocene or early Miocene. Later (Pliocene?), a component of left lateral shear occurred across the entire Makran Zone in association with the opening of the newly identified Haman-i-Mashkel fault trough S of the Chagai Hills and W of the Ras Koh. The total displacement and displacement rate across the Chaman transform zone varies in response to the rates of convergence in the plates E and W of the zone.

    Publication Date: 2017-07-13
    Description: Many of the difficulties of staining plastic embedded tissues for light and electron microscopy derive from physical exclusion of hydrophilic staining reagents by hydrophobic embedding media. Structures which stain most intensely with hydrophilic reagents usually contain less hydrophobic plastic than do non-staining structures. Such incomplete infiltration is apparently caused by exclusion of viscous, hydrophobic monomers by physically dense and/or well hydrated tissue elements. In keeping with this, generalized staining of tissues embedded in hydrophobic media does occur when hydrophobic reagents are used. Staining of plastic-free structures with single hydrophilic reagents or with sequences of such reagents, is, however, largely rate-controlled. The surprising similarity of hydrophilic and hydrophobic plastic embedding media is discussed. Limits of this simple model are explored, with a consideration of the roles of fixative and of monomer-tissue reactions

    Description: Les données géologiques et géophysiques recueillies dans le golfe de Gascogne depuis 12 ans ont été partiellement réinterprétées d'après les forages IPOD du leg 48, et une nouvelle carte structurale en couleurs a été établie〈1〉. Cette carte montre la profondeur et l'extension du socle océanique et de la croûte continentale, amincie par les phases de distension mésozoïques et/ou épaissie par les phases de compression cénozoïques. Les structures sont classées d'après leur âge et leur nature: failles normales et décrochantes, témoins du « rifting » des marges armoricaine et aquitaine du Néocomien à l'Aptien; failles transformantes de la plaine abyssale, contemporaine de l'ouverture océanique de golfe à l' Albien et au Crétacé supérieur jusqu'au Santonien ; chevauchements, failles inverses, prismes d'accrétion tectonique, décrochements,failles normales et horsts créés par la subduction de la plaque européenne sous l'Ibérie du Maestrichtien (?) à l'Éocène moyen; enfin, structures tardives dues au rejeu à l'Oligocène ou au Miocène des accidents tectoniques antérieurs. Ces données structurales sont compatibles avec un modèle cinématique selon lequel l'Ibérie a subi, par rapport à l'Europe stable, au moins trois rotations successives depuis le Jurassique: déplacement en direction du sud-ouest au Crétacé inférieur jusqu'à l' Aptien supérieur; divergence et mouvement vers le sud-est de l' Aptien terminal au Santonien ; enfin, convergence et mouvement en direction du nord-ouest au Paléocène et à l'Éocène inférieur. IPOD drillings on the armorican margin allow to review geological and geophysical data collected in the Bay of Biscay for the past twelve years. They also allow to draw up a new structural sketch. The sketch displays the depth and extension of oceanic and continental basement. Structures fall into four catégories: 1) Neocomian-Aptian normal and associated probable strike-slip faults, related to the rifting of the armorican margin; 2) Albian-Santonian transform faults within the oceanic basement, resulting from the iberian rotation and correlative opening of the Bay of Biscay; 3) Maestrichtian(?)-middle Eocene thrusting, reverse faults, strike-slip faults, accretionary tectonic prism and normal faults linked to the subduction of the european plate beneath the north-spanish margin emphasised by a fossil marginal trench and a bulging of the deeping plate; and 4) Oligocene-Miocene reverse, normal and strike-slip faults. The structural data agree with a three phases kinematic model: a) Néocomian-Aptian NE-SW motion of the iberian plate with respect to the stable Europe (rifting); b) AlbianSantonian NW-SE drifting of lberia (and related oceanic accretion within the Bay); c) Paleocene-lower Eocene SE-NW converjence resulting in subduction of the european plate beneath the Iberian plate and subsequent shortening and thickening of the north-spanish margin.

    Description: Samples collected at hourly intervals on May 18–19, 1980, at three sites 200 km downwind from Mount St. Helens, have made possible a detailed reconstruction of the conditions that contribute to the compositional heterogeneity of mineral and glass components observed in distal tephra layers. The air fall tephra deposited at the sites during the first 7 hours of the May 18 eruption is mostly coarse grained, microlite-rich, nonjuvenile glass and feldspar. Grain-size maxima in this initial tephra can be related to the cataclysmic blast at 0832 and a subsequent pulse of the eruption at 1200. Juvenile, microlite-free glass increases in relative abundance at the sampling sites beginning at about 1900. Such a change between nonjuvenile and juvenile tephra can be related to a 5-km increase in column height associated with the last major pulse of the eruption which occurred at 1700 at the volcano. Electron microprobe study of both microlite-rich and microlite-free pumice in the time series samples reveals significant compositional differences. Interstitial glass in nonjuvenile pumice deposited during the first few hours at the sampling sites is enriched in SiO2 and K2O and depleted in TiO2, FeO*, and MgO relative to juvenile glass. By comparison, major element composition of the least evolved juvenile glass sampled during the last several hours of the eruption displays a slight trend toward less evolved composition. Least squares calculations suggest that the more evolved character of the nonjuvenile glass can be explained by greater fractional crystallization brought about by enhanced cooling in a cryptodome prior to eruption, whereas the temporal changes observed in juvenile glass composition during the last several hours of the eruption suggest the presence of a small, slightly zoned magma chamber at depth. Electron microprobe study of glass-coated ilmenites, magnetites, and plagioclases provides the following estimates of the physical conditions in this reservoir: 865°±50°C, PH2O = 2.2 kbar and -log ƒO2 = 11.7. Analyses of bulk pumice, glass and selected mineral phases from May 25, June 12, July 22, and October 16–18 pumices erupted from Mount St. Helens indicate that the bulk pumice (magma) compositions have become slightly more andesitic with time, while mineral and co-existing glass compositions have changed significantly in post-May 18 eruptions with both being more highly evolved than those associated with the May 18 eruption. An application of the magnetite-ilmenite geothermometer to June 12 and July 22 samples indicates temperatures of 919°±30°C and 930°±50°C, respectively. Least squares calculations suggest that such evolved post-May 18 glass and mineral phases can be derived by fractional crystallization of a magma composition like bulk May 18 pumice into approximately 50% crystals and 50% residual liquid. Such partitioning between crystals and residual liquid appears to have occurred on the scale of centimeters and is interpreted as a consequence of accelerated crystallization under reduced water pressure.

    Description: Studies of sexual maturation have been made on a large sample of Eledone cirrhosa from the North Sea off Aberdeen, Scotland. In females the wet weights of the ovary and oviducal glands have been recorded for a wide range of body sizes and related to the total body weight. The length dlstribution of a sample of eggs from each ovary was also measured. Assessed either by ovary enlargement or the mean egg length, female E. cirrhosa become mature at a wide ränge of body size and so state of maturity is not predictable from size of the animal. In males the total weight of genital bag is, by contrast, clearly correlated with body weight although this is not true for testis alone, presumably because of transfer of sperm from testis to spermatophoric sac.

    Description: Changes in the relative size of the ovary, oviducal glands and eggs are described for Eledone cirrhosa captured from the North Sea off Aberdeen over a 3 year period (N = 488). The analysis is based only on freshly caught animals, excluding those held in aquarium conditions (〉 5 days). Ovary enlargement and egg size estimates are used as indices of sexual maturity. Between 0–15% and 18–95% of total body weight is contributed by the ovary. Maximum egg length in the ovary ranges up to 7 mm. On these criteria, sexual maturation typically occurs at body sizes between 400–1000 g although some animals of 1000–1200 g are found showing no evidence of ovary enlargement. The majority of the monthly sample is always immature but maturation can apparently occur at almost any time of the year. Increase in mean ovary index and mean values for egg size are strongly seasonal and indicate a peak incidence of sexual maturity over 2–3 months in the July-September period. Spawning is presumed to follow within 1 month. Estimates of the fecundity of the females, based on the egg sample from the ovary, range from 2·2 × 103 to 55 × 10 3 eggs with a mean of 11 × 10 3 and a mode of 7·5 × 10 3 eggs.

    Description: The ‘magnetic quiet zone’ in the eastern Gulf of Aden is located between the oceanic crust of Sheba Ridge and the continental crust of Arabia and Somalia, and is separated from both by important structural boundaries. The seaward boundary is marked by the end of the seafloor spreading magnetic anomaly sequence and by a basement depth discontinuity. The landward boundary is marked by escarpments made up of a series of normal faults. These escarpments extend from 2–3 km below sea-level to 1500 m above sea-level and are equivalent of the ‘hinge zone’ found at mature continental margins. The magnetic field in the quiet zone is flat in some areas and in others is characterized by anomalies of up to several hundred gammas which are correlatable over distances of up to about 20 km and which appear related to basement topography. The basement lacks the topographic slope characteristic of mid-ocean ridge flanks and is characterized by moderately rough relief. The crustal structure appears quite heterogeneous and where the crustal thicknesses have been determined, they are slightly greater than those of oceanic crust. New heat flow measurements show high values (95.7–123.3 mW m−2) in the quiet zone with values decreasing from Sheba Ridge toward the coast. The unusual structure of the quiet zone and the observations that more opening appears to have occurred between Arabia and Somalia than can be accounted for by the oceanic crust of Sheba Ridge leads to the suggestion that the magnetic quiet zone was generated by diffuse extension of continental crust through a combination of rotational (listric) faulting and dyke injection. This possibility is investigated using both a ‘stretching’ or ‘lithospheric attenuation’ model and a model in which a portion of the extension occurs through dyke injection. It is found that these models can adequately match the observed heat flow and basement depths although very large amounts of extension (β=4–6) are required in the deep seaward portion of the quiet zone. This results in more extension than is compatible with the documented motion between Arabia and Africa. However, formation of the magnetic quiet zone occurred over a period of 10–15 Myr rather than instantaneously as assumed in the simple models. When the effects of a finite length rifting episode are considered, less extension is required and the observed geophysical data are consistent with a diffuse extension origin for the magnetic quiet zone.

    Description: Gut content analyses have shown that the diet of the long-finned squid, Loligo pealei, differs between inshore spawning and nursery grounds and offshore winter grounds. In this study, squid were collected inshore from May through November in lower Narragansett Bay, Rhode Island and offshore during winter along the continental shelf between Cape Hatteras and Cap Cod. In both collections crustaceans were more frequently consumed than either fish or squid, but fish were eaten by a wider size range of squid and more frequently inshore. Prey-type selection based on size was common in both samples, but it is unlikely that the species composition is the same in both areas. These data suggest that L. pealei is a highly opportunistic predator, whose diet primarily reflects the local abundance of potential prey species. Such a flexible feeding strategy could account for the large spatial and temporal variations which have been reported in the diet of this squid from various offshore areas.

    Description: The oldest igneous rocks on Maio are pillow lavas of Mid-Ocean Ridge pillow basalts character which have been tilted and uplifted about 4 km from the ocean floor to outcrop as a partial ring, dipping steeply away from a central plutonic complex made up of pyroxenites, essexites, syenites and carbonatites. The ocean floor volcanic rocks are overlain conformably by a stratigraphically continuous pelagic carbonate succession which demonstrates a shallowing depositional environment from the Upper Jurassic to Upper Cretaceous times, when tuffaceous beds indicate renewed volcanism. The tuffs are associated with rudites demonstrating the emergence of the island and amongst the clasts are plutonics indicating Upper Cretaceous magmatism and the unroofing of the volcano to a substantial depth. Deformation under compressive stress resulted in the folding and local repetition by thrusting of this sedimentary cover, which, together with the plutonic core, had been intensively injected by major sills. The Mesozoic succession has been planed off and overlain with marked unconformity by a largely Neogene sequence of volcanic and terrestrial sedimentary rocks. There is a hiatus throughout the Palaeogene, and constructional activity appears to recommence with ankaramitic hyaloclastite and lava deltas and subaerial ankaramitic flows. These are overlain by fluvial sediments and tuffs. Stratigraphically above these is an extensive plateau of silica-undersaturated lavas, olivine-melilitites and nephelinites, which rest on a planed and locally lateritized surface. At topographically higher levels in the eastern part of the island there are thick ankaramitic lavas and pyroclasts which evidently flowed eastward through valleys cut down into the Mesozoic strata, and appear to be of Pliocene age. The subsequent history of the island appears to be non-volcanic.

    Description: Several specimens of the remarkable finned octopod Cirrothauma recently caught are described. The animal is taken at great depths, often near the bottom but sometimes away from it. The enormous arms and web can be spread to give a medusoid form but the animal also swims horizontally mainly using the fins, whose powerful muscles are attached to a large fin support. The animal is gelatinous and perhaps neutrally buoyant, and can almost certainly hover in the medusoid form. The mantle muscles are weak and the funnel very long. The arms are long and have a few small suckers in a single longitudinal row, only some of which have a minute suction chamber. The infundibula are small but the cuticle has small pegs with innumerable pores. The cuticle is closely similar to that of octopods and is capable of adhesion. In the base of each sucker peduncle, male and female, there is a possible light organ. The beaks are large and black, the lower strongly pointed. There is a large tongue with vestiges of a radula. The salivary papilla carries the duct of the `posterior salivary gland' which lies far forward within the buccal complex. The male ducts are simple and produce simple packets of sperms. These are found in the oviducal gland (spermatheca), where the large eggs are fertilized. The heart has an accessory chamber presumably providing extra blood flow to the long arms and large fins. The eyes are small open cups covered by a cornea but with no lens or iris. The rhabdomes are sometimes degenerate. The optic lobe is small with no granular layers of amacrine cells. The suboesophageal lobes are close together and the superior buccal lobe is attached to the brain, as in incirrate octopods. There is a large fin lobe. The peduncle lobe and basal lobes are large, in spite of the small eyes, indicating their importance for locomotion. There are no giant fibres. The supraoesophageal lobes are small, with development only of the tactile region (inferior frontal lobe) and reduction of the superior frontal and vertical lobe system. There are large epistellar bodies but no cranial photosensitive vesicles. The optic gland is clearly of neural origin. The statocysts are very large and typically octopodan with a single macula and one anticrista, but the crista is not subdivided. Cirrothauma, like other cirrates, thus shows some features that are present in Vampyroteuthis, and others that are found in decapods, as well as many present in the octopods without fins. These animals represent in some ways an early condition of the coleoid stock.

    Description: The feeding biology was investigated of a population of the nordic krill Meganyctiphanes norvegica which inhabits a semi-enclosed deep near the danish island Läsö. The food composition was determined during one year in monthly samples. The analysis of the stomach contents showed a remarkable diversity. Cannibalism is common, Detritus and undigestible matter form a major part of the compounds at all times of the year. The investigation of the feeding appendages gave evidence that the spectrum of food particles fed is determined by the mechanical properties of the fil tering basket. Optical control of the food is not possible because of the insufficient resolution of the eyes. This explanation of the unspecific food requirements was supported by observations on the feeding behavior. The eyes reveal a high sensibility to perceive even very dim light in contrast to their poor resolution of fine details. This feature illustrates the major role of the eyes in the control of vertical migration and orientation. Quantitative aspects of the feeding biology are dealt within the last chapter. The determination of the amount of food contained in the stomachs allowed to quantify the feeding intensity of the nordic krill. A energy budget based on recent findings is presented and its reliability discussed.

    Description: The behaviour of Chelophyes has been analysed from the point of view of coordination between stem and nectophores, and an electron microscope study of the effectors and conducting elements has been carried out. Coordination between the stem and anterior nectophore involves two pathways, one epithelial and the other nervous. The nervous link consists of a bundle of small neurites and a single giant axon. There is some evidence that this mediates rapid escape behaviour. After the nerves have been cut, coordination is maintained via the epithelial route. Impulses can jump from epithelial cells into nerves but the transmission process is unclear. Neuro‐epithelial transmission involves conventional synapses. As in physonectid siphonophores, the stem has two nervous systems each with its own giant fibre, and a slow system, the endodermal epithelium. In the nectophore, marginal nerve centres generate a swimming rhythm. Conduction in the subumbrellar muscle is myoid. The exumbrellar epithelium and the subumbrellar endoderm are conducting tissues. Histological study reveals synapses in the predicted locations and gives details of myo‐epithelial organization and nervous layout. Novel histological features include elements resembling steroid‐secreting cells, which ensheath nerves and are innervated by them, and innervated giant non‐nervous cells lying between the nerve ring and the hydroecium. The subumbrellar muscle cells are shown to have sarcolemmal invaginations reminiscent of the f‐tubule system of vertebrate muscle.

    Description: The authors believe that Globorotalia mayeri Cushman and Ellisor and Globorotalia siakensis LeRoy cannot be maintained as separate taxa. This opinion comes after reexamination of the holotype of Globorotalia mayeri and of additional illustrations of the holotype of Globorotalia siakensis together with examination of large numbers of specimens of the plexus from Bodjonegoro-1 well in Java and from Trinidad in the Caribbean. Both taxa were described in 1939 but, due to the rules of priority, Globorotalia mayeri would now be the valid name. We consider that Globorotalia continuosa Blow is a four-chambered variant of Globorotalia mayeri that cannot usefully be separated from it.

    Description: The major light and dark components of body displays are described and classified for the octopus Eledone cirrhosa (Lamarck) under aquarium conditions. Comparisons are made with Octopus vulgaris and Eledone moschata. Upon the basic similarity of white display components in the three species is superimposed a trend of modification. Dark components are less various in Eledone cirrhosa and although the chromatophores are organised with leucophores into chromatic units these are not clearly limited morphologically by “grooves”. The mottle patterns of Eledone seem to be arranged along the longitudinal and latitudinal (radial) axes of the animal, the grade of mottle does not respond to grade of background contrast.

    Description: During a 10-year study more than 2,000 phytoplankton samples were collected from the entire coast of Peru and analyzed. In general, diatoms were the most abundant group of organisms in all seasons. Predominant species were Rhizosolenia delicatula, Skeletonema costatum Thalassiosira subtilis, Thalassionema nitzschioides and several species of the genus Chaetooeros. Dinoflagellates and flagellates were observed frequently during summer. The mean distribution of the phytoplankton concentration during the 10 years shows the existence of several centers with higher cell densities along the coast, coinciding with the areas of more intense and persistent upwelling. Four major centers have been identified: Pimentel (˜6°S), Chimbote (˜9°S), Callao (˜12°S), and Tambo de Mora-Pisco (˜15°S); and two minor centers, Talara (˜4°S) and Ilo (˜17°S). The relative importance of each center seems to change according to the season. The highest phytoplankton concentration tended to be in the northern part of the coast during fall and winter and in the south through spring and summer.

    Description: Sponges are diploblastic acoelomate Metazoa. They are sedentary, filter-feeding animals which utilize a layer of flagellated cells to pump a unidirectional water current through themselves. They are found in freshwater, but more abundantly in marine habitats. Sponges have been persistent throughout geological time from the Precambrian to the Recent, with special success during the Paleozoic. They are apparently the most primitive multicellular animals on a phylogenetic scale ranked by morphological complexity, although the levels of physiological and biochemical complexity found in sponges easily measure up to the degree of sophistication found in so-called higher animals. The Porifera (sponges) and Coelenterata are related as two phyla representing distinct stocks, but stemming from a presumed common although presently unknown origin (Hyman, 1940).

    Description: The type species of Dictyonema is D. retiforme Hall, 1851 from the Middle Silurian Rochester Shale of New York. Although incomplete, the type specimen probably belongs to the benthic group of dendroid graptolites which ranged from the Late Cambrian to early Late Carboniferous. It is proposed that the plank tie, near-cosmopolitan 'Dictyonema' flabelliforme is phylogenetically quite distinct and belongs to the unattached coni-siculate dendroid family Anisograptidae Bulman, with Radiograptus Bulman as probable ancestor. The Anisograptidae are not directly related to the benthic dendroid family Dendwgraptidae Roemer, of which Dictyonema is a member, although they may be indirectly descended from it. The planktic species 'Dictyonema' flabelliforme is revised and referred to the genus Rhabdinopora Eichwald, 1855. 'Dictyonema' norvegicum Kjerulf and 'D' graptolithinum Kjerulf are regarded as junior synonyms of Rhabdinopora flabelliformis (Eichwald). The coni-siculate planktic family Anisograptidae is reorganized into three subfamilies. The Anisograptinae n. subfam. includes essentially horizontal pauci- or non-dissepimentous genera (Radiograptus, Staurograptus, Anisograptus, Adelograptus, Aletograptus, Triograptus and Kiaerograptus); the Rhabdinoporinae n. subfam. includes pendent conical genera (Rhabdinopora, Bryograptus and doubtfully Sagenograptus); and the (possibly polyphyletic) Clonograptinae n. subfam. includes horizontal forms principally developing from a single dicalycal bud of th11 (Cionograptus, Temnograptus, ?Stellatograptus).

    Description: We studied the alteration of silicic volcanic glass of recent Towada ash in the different soil environments by means of electron-microprobe analysis. Two types of glass alteration (tentatively named [alpha] and [beta] types) were established and were distinguished on the basis of potassium and calcium contents of the glass samples. The [alpha] type glass alteration was characterized by a very large gain of potassium and a large loss of sodium. This alteration was explained by the ion exchange reaction between Na+ and H+ plus K+ without significant change in the glass structure. The [beta] type alteration characteristically showed a significant loss of potassium and a large gain of calcium and some other elements. The behaviors of alkalies and alkaline earths in the [beta] type glass could not be interpreted by the stoichiometry of exchange processes of these elements. Changes of glass structure during weathering were suggested for the [beta] type glass. There were close relationships between the mode of glass alteration, clay mineralogy of ash-derived soils, and soil environments. Only [alpha] type glass alteration was observed in the 2:1 mineral soils that showed the very low pH, very low contents of exchangeable bases, but relatively high content of exchangeable potassium. In contrast the [beta] type glass alteration was the most intense in the allophanic Ando soil, which showed a relatively high content of exchangeable bases and a high pH.

    Description: The boundaries of the mud area of the inner German Bight have been mapped w1th a subbottom echo sounder. The echo profiles reveal a uniform sediment body which is chararterized by the occurrence of mud (clayey silt) in separate layers. The western part of the area is dominated by mud showing fine-sand intercalations, the well-known storm sand layers. The eastern part consists of fine-sand /mud alternate bedding. Primary stratification may be altered by bioturbation, particularly in the western part. However, the echographic uniformity of the mud area is almost independent of the regional variations of facies. At the southern, western, and northern boundaries the mud-area sediment body wedges out above the adjacent, more sandy sedimems. The eastern boundary is a system of sand tongues and channels with fine-sand/mud alternate bedding. Here, interfingering of sand and sand/mud facies may be a typical pattern in the depositional sequence due to occasional shifting of both sand tongues and channels. Based on hydrographic data from the German Bight the origin of the mud was ascribed mainly to the suspension load of the river Elbe. The suspended matter is transported towards north by the "Elbe water mass" which is a particular water body with lower salinity, as compared with surrounding North Sea waters. Main part of the suspension load is, however, deposited in the inner German Bight. The limits of mud deposition are given by the western and eastern boundaries of the "Elbe water" body as well as by shallower sand ridges surrounding the mud area in the south, east, and west.

    Description: Living specimens of Globigerinoides sacculifer (Brady) were subjected to varying degrees of damage in 2 series of experiments. In the first 3-group experiment, one, two or all chambers of the shells were crushed, whereas in the second 3-group experiment, successive chambers were amputated from the shells. The purpose of both sets of experiments was to determine the relative rate of recovery of and mode of shell regeneration by the injured organisms. The great majority in 5 of the 6 groups recovered and continued shell growth by regenerating spines, cementing broken parts, adding new chambers and undergoing gametogenesis. The shell shapes which resulted from the crushed specimens were generally bizarre, whereas the amputated specimens regrew chambers of normal shape. The nucleus in adult G. sacculifer shells appears to be located in the F-3 or earlier chamber. Our experiments indicate that in spite of severe injury to the shell, these tenacious marine protozoans can generally restore their biological functions of calcification, predation, symbiosis with algae, and gametogenesis. In nature, abnormal shells which show evidence of physical damage are most likely caused by predators; thus their frequency reflects a relative predation pressure on planktonic foraminifera.

    Description: Abundance and size of manganese nodules lying on the ocean ftoor can be computed from multi-frequency sounding data from a survey vessel. This paper shows how individual nodule scattering response is synthesized to obtain equivalent reftectivity of nodule deposits. Then quantitative ways of measuring nodule coverage or abundance are developed so that they can be linked to acoustic responses. Examples are worked out and the Sumitomo method of synthesizing acoustic response is described.

    Description: Although motion between Arabia and Africa is presently occurring along the entire length of the Red Sea, the morphology and tectonics that result from this motion vary greatly along its length. South of 21°N, the main trough is bisected by a deep axial trough which has formed by sea-floor spreading during the past 4 m.y. and is associated with large-amplitude magnetic anomalies and high heat flow. North of 25°N, an axial trough is not present and the floor of the main trough has an irregular faulted appearance. The magnetic field in the north is characterized by smooth low-amplitude anomalies with a few isolated higher amplitude magnetic anomalies commonly associated with gravity anomalies and in many places probably due to intrusions. Between these regions, the axial trough is discontinuous with a series of deeps characterized by large-amplitude magnetic anomalies alternating with shallower intertrough zones which lack magnetic anomalies. It is argued that the different regions represent successive phases in the rifting of a continent and the development of a continental margin. An initial period of diffuse extension by rotational faulting and dike injection over an area perhaps 100 km (60 mi) wide is followed by concentration of extension at a single axis and the initiation of sea-floor spreading. The main trough in the southern Red Sea, away from the deep axial trough, formed during the Miocene by the same processes of diffuse extension that are still active in the northern Red Sea. This model explains the available geologic and geophysical data and reconciles previous models for the formation of the Red Sea which emphasize either the evidence for considerable motion between Arabia and Africa or the evidence for down aulted continental crust beneath much of the Red Sea. The initial pre-sea-floor spreading stage results in considerable extension (160 km or 100 mi) at 25°N in the Red Sea), can last for several tens of millions of years, and is an important factor in the development of the continental margin. Such an extended phase of rifting and diffuse extension must be taken into account in studies of sedimentation, subsidence, and paleotemperatures.

    Description: The growth of the octopus Eledone cirrhosa has been studied in a population from the North Sea off Aberdeen. Data are presented for the growth of individuals isolated in aquarium conditions; the growth of size classes in thefieldpopulation; and preliminary information on the growth relationships of gonad, somatic, cardiac and brain components of the body. At 15 °C Eledone cirrhosa is capable of growing from 10 to 1000 g in 270 days. From octopuses which feed readily in captivity, weight specific growth rates of up to about 3–5 % day-1 for animals of 100 g body weight are recorded, falling to a maximum of about 1–5 % day-1 at body sizes above 500 g. Females stop growing when sexually mature, but in the sample captured they were consistently larger than males, a feature which may account for the 7:1 bias towards the incidence of females. On a wet-weight basis, the mean food incorporation into growth is 37 % of the food ingested, which is 49% of the gross weight of crabs killed. Field data for 1978/79 suggest that animals recruited to the population at the beginning of the year grew steadily until December, overwintered without growing, then grew rapidly for several months in the subsequent year before disappearing from the samples. The estimated average age of those animals and by implication, the life span, is 20 months.

    Description: During a recent deep ocean research expedition, conducted by International Underwater Contractors, an important research project utilized the world's deepest, unmanned, untethered vehicle called the Epaulard. This Remotely Operated Vehicle (ROV) is capable of descending to 6100 meters; conducting a straight, grid or complex pattern survey over 12 nautical miles while taking 5000 high-quality black white photographs; and then ascending to the surface for recovery. It uses the latest in microprocessor technology to control its onboard components. The project took place in the summer of 1983 approximately 113 kilometers offshore Coos Bay, Oregon, in excess of 3600 meters of water. It was conducted in the area known as the Gorda Rift and the Juan de Fuca ridge where previous surveys have indicated the possibilities of significant amounts of polymetallic sulfides. The mission was considered a total success because the vehicle was able to take approximately 15,000 photos over a 5-day mission.

    Description: Mesozoic deep water sedimentary rocks uplifted and exposed in basement complexes on the islands of Fuerteventura (Canary Islands) and Maio (Cape Verdes) help document the early Atlantic ocean and the volcanic history of these islands. On Fuerteventura ca. 1.5 km of terrigenous quartzose clastics, black shales, and subordinate redeposited limestones of early Cretaceous age are overlain first by Albian-Cenomanian marls and clastics, showing extensive soft sediment slumping, then after a hiatus by Senonian nannofossil chalks with chert nodules. After a further break alkalic submarine volcanic rocks, largely hyaloclastics, were erupted, then overlain by redeposited bioclastic limestones and volcaniclastics of Oligocene age. A dyke complex was intruded, then the basement complex was uplifted, peneplaned, and overlain by Neogene plateau lavas. On Maio the basement complex comprises mafic pillow lavas of midocean ridge character overlain by up to 4 00 m of deep water sedimentary rocks. Upper Jurassic to lower Cretaceous radiolarianrich pelagic limestones are succeeded by middle and upper Cretaceous sequences of mudstones, redeposited limestones, chalks, tuffs, and volcaniclastics which document the onset of volcanism. During a sedimentary hiatus plutonic rocks were intruded, uplifted, then eroded to produce conglomerates of late Miocene age. These are overlain by several series of gently dipping subaerial alkaline basalt flows. Comparisons with D.S.D.P. sites, oil wells and on land geology confirm that the lower Cretaceous Fuerteventura quartzose clastics formed part of a deep water fan complex located close to the Atlantic continent-ocean boundary. Comparable flysch is known in the Moroccan basin, in the Betic-Maghrebide system and the feeding Tan-Tan-Cape Bojador delta system. The inferred disconformity between Cenomanian and Senonian is part of a widespread depositional hiatus associated with slumping on the adjacent west African continental margin. On Maio pelagic limestones comparable with the Tethyan Maiolica facies were deposited on a subsiding? middle/late Jurassic ocean ridge before uplift related to onset of volcanism probably in the late Cretaceous.
