    Calcium carbonate preservation in the equatorial Pacific (1991)

    Description: The Pliocene-Pleistocene history of CaCO3 preservation in the central equatorial Pacific is reconstructed from a suite of deep-sea cores and is compared to fluctuations in global ice volume inferred from delta18O records. The results are highlighted by: (1) a strong covariation between CaCO3 preservation and ice volume over 104 to 106 year time scales; (2) a long-term increase in ice volume and CaCO3 preservation since 3.9 Ma demonstrated by a deepening of the lysocline and the carbonate critical depth; (3) a dramatic shift to greater CaCO3 preservation at 2.9 Ma; (4) distinctive ice-volume growth and CaCO3 preservation events at 2.4 Ma, which are associated with the significant intensification of northern hemisphere glaciation; (5) a mid-Pleistocene transition to 100-kyr cyclicity in both CaCO3 preservation and ice volume; and (6) a 600-kyr Brunhes dissolution cycle superimposed on the late Pleistocene glacial/interglacial 100-kyr cycles. CaCO3 preservation primarily reflects the carbonate chemistry of abyssal waters and is controlled by long-term (106 year) and short-term (104 to 105 year) biogeochemical cycling and by distinct paleoclimatic events. We attribute the long-term increase in CaCO3 preservation primarily to a fractionation of CaCO3 deposition from continental shelf to ocean basin, and secondarily to a gradual rise in the riverine and glaciofluvial flux of Ca++. On shorter time scales, the fluctuations in CaCO3 preservation slightly lag ice volume fluctuations and are attributed to climatically induced changes in the circulation and chemistry of Pacific deep water.

    Pollen analysis of surface sediments from the Gulf of Guinea and offshore NW-Africa (1991)
    PANGAEA
    In:  Supplement to: Dupont, Lydie M; Agwu, Chiori O C (1991): Environmental control of pollen grain distribution patterns in the Gulf of Guinea and offshore NW-Africa. Geologische Rundschau, 80(3), 567-589, https://doi.org/10.1007/BF01803687

    Description: The areas of marine pollen deposition are related to the pollen source areas by aeolian and fluvial transport regimes, whereas wind transport is much more important than river transport. Pollen distribution patterns of Pinus, Artemisia, Chenopodiaceae-Amaranthaceae, and Asteraceae Tubuliflorae trace atmospheric transport by the northeast trades. Pollen transport by the African Easterly Jet is reflected in the pollen distribution patterns of Chenopodiaceae-Amaranthaceae, Asteraceae Tubuliflorae, and Mitracarpus. Grass pollen distribution registers the latitudinal extension of Sahel, savannas and dry open forests. Marine pollen distribution patterns of Combretaceae-Melastomataceae, Alchornea, and Elaeis reflect the extension of wooded grasslands and transitional forests. Pollen from the Guinean-Congolian/Zambezian forest and from the Sudanian/Guinean vegetation zones mark the northernmost extension of the tropical rain forest. Rhizophora pollen in marine sediments traces the distribution of mangrove swamps. Only near the continent, pollen of Rhizophora, Mitracarpus, Chenopodiaceae-Amaranthaceae, and pollen from the Sudanian and Guinean vegetation zones are transported by the Upwelling Under Current and the Equatorial Under Current, where those currents act as bottom currents. The distribution of pollen in marine sediments, reflecting the position of major climatic zones (desert, dry tropics, humid tropics), can be used in tracing climatic changes in the past.

    Sedimentology on cores off the South Orkney Plateau (1991)

    Description: Grab samples and cores for sedimentological studies were retrieved along a N-S transect of the South Orkney Plateau margin. On the basis of morphology, the margin has been subdivided into shelf, upper continental slope, and a lower slope region cut by basins and ridges. Grain size, Sand component, and clay mineralogy were determined as well as water, organic carbon and carbonate contents. In addition, vane shear strength, magnetic intensity and the proportion of ice-rafted debris were measured, dating was done by detailed magnetic stratigraphy, the biofluctuation of the radiolarian Cycladophora davisiana and 230-Thorium analyses. Sediment facies distribution is controlled by numerous factors such as regional bathymetry and circulation, biogenic productivity, seasonal ice cover and the deposition of terrigenous detritus by ice-rafting, bottom water transport and/or slumping. The complex interrelationship between these factors results in three main categories of sediment facies. The diamict facies is interpreted as an interglacial facies. It is composed of clayey silt and silt and is characterised by a large component of coarse, ice-rafted material such as gravel and sand (IRD). This generally strongly bioturbated sediment contains radiolarian and diatom-rich layers as well as horizons of lower water and organic carbon content. Magnetic intensities, related to volcanic ash particles, glauconite, and micromanganese nodules as well as a large quantity of rock fragments, are low. The biosiliceous and IRD content decreases from north to south along the South Orkney transect because of seasonal ice margin fluctuations, thus resulting in barren and IRD-poor interglacial deposits in the southern region. Apart from ice-rafting and biogenic productivity, bottom currents also exert a strong control on the distribution of this facies. Strong and fluctuating bottom current influence is documented by the sediment structures in this facies. The homogenous clay facies was deposited during glacial periods. These silty clays are generally barren with little ice-rafted material or rock fragments because of ice cover during glacial periods. The homogenous clay facies was probably deposited by bottom currents (contourite). In comparison to interglacial periods, current velocities during glacial periods must have been relatively weak due to the decreased formation of Antarctic Bottom Water and reduced water mass circulation. The homogenous clays are additionally characterised by higher water and organic carbon contents as well as higher magnetic intensity. They are only weakly bioturbated with burrows size smaller than in the diamictite facies. A bioturbated clay-size facies, with a composition similar to that of the diamictite facies, was deposited during the glacial to interglacial transition. The difference lies in the lower IRD and microfossil content. A weak current regime is indicated by the texture and sediment structures. On the basis of sediment sequences, three glacial and four interglacial periods have been distinguished in cores PS1175-3, PS1170, and PS1167-9. The time span ranges from the Holocene to the interglacial at 340,000-300,000 Y. Increased IRD deposition by icebergs and an increase in the production of siliceous organisms occured during the maximum of the last glacial due to several short surges of the Antarctic ice shelf.

    Description: Radiocarbon ages on CaCO3 from deep-sea cores offer constraints on the nature of the CaCO3 dissolution process. The idea is that the toll taken by dissolution on grains within the core top bioturbation zone should be in proportion to their time of residence in this zone. If so, dissolution would shift the mass distribution in favor of younger grains, thereby reducing the mean radiocarbon age for the grain ensemble. We have searched in vain for evidence supporting the existence of such an age reduction. Instead, we find that for water depths of more than 4 km in the tropical Pacific the radiocarbon age increases with the extent of dissolution. We can find no satisfactory steady state explanation and are forced to conclude that this increase must be the result of chemical erosion. The idea is that during the Holocene the rate of dissolution of CaCO3 has exceeded the rain rate of CaCO3. In this circumstance, bioturbation exhumes CaCO3 from the underlying glacial sediment and mixes it with CaCO3 raining from the sea surface.

    Benthic foraminifera and accumulation rates in different time slices of sediment cores from the Equatorial Pacific (1991)

    Description: Surface productivity is correlated with the rate of accumulation of benthic foraminifera on the deep-sea floor. As a rule of thumb, for each 1 mg of organic carbon arriving at the sea floor, one benthic foram shell 〉150 µm is deposited. The correlation can be used to reconstruct organic flux to the sea floor in the past, and hence the productivity of past oceans. Applying the appropriate equations to box core data from the Ontong Java Plateau in the western equatorial Pacific, we found that productivity during the last glacial maximum exceeded present productivity by a factor of between 1.5 and 2.0, with intermediate values for the mid-transition period. Accumulation of benthic foraminifera was depressed on top of the plateau during the glacial and transitional period, presumably because increased winnowing removed part of the food supply.
