    Age determination of Southeast Atlantic sediment cores (2004)

    In:  Supplement to: Versteegh, Gerard J M; Schefuß, Enno; Dupont, Lydie M; Marret, Fabienne; Sinninghe Damsté, Jaap S; Jansen, J H Fred (2004): Taraxerol and Rhizophora pollen as proxies for tracking past mangrove ecosystems. Geochimica et Cosmochimica Acta, 68(3), 411-422, https://doi.org/10.1016/S0016-7037(03)00456-3

    Description: Angola Basin and Cape Basin (southeast Atlantic) surface sediments and sediment cores show that maxima in the abundance of taraxerol (relative to other land-derived lipids) covary with maxima in the relative abundance of pollen from the mangrove tree genus Rhizophora and that in the surface sediments offshore maxima in the relative abundance of taraxerol occur at latitudes with abundant coastal mangrove forests. Together with the observation that Rhizophora mangle and Rhizophora racemosa leaves are extraordinarily rich in taraxerol, this strongly indicates that taraxerol can be used as a lipid biomarker for mangrove input to the SE Atlantic. The proxy-environment relations for taraxerol and Rhizophora pollen down-core show that increased taraxerol and Rhizophora pollen abundances occur during transgressions and periods with a humid climate. These environmental changes modify the coastal erosion and sedimentation patterns, enhancing the extent of the mangrove ecosystem and/or the transport of mangrove organic matter offshore. Analyses of mid-Pleistocene sediments show that interruption of the pattern of taraxerol maxima during precession minima occurs almost only during periods of low obliquity. This demonstrates the complex environmental response of the interaction between precession-related humidity cycles and obliquity-related sea-level changes on mangrove input.

    Offsets applied to construct the revised composite depth to cores, ODP Site 175-1077 (Table T1) (2001)
    PANGAEA
    In:  Supplement to: Jansen, J H Fred; Dupont, Lydie M (2001): Data report: A revised composite depth record for Site 1077 based on magnetic susceptibility and XRF (CORTEX) data. In: Wefer, G; Berger, WH; Richter, C (eds.) Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 175, 1-10, https://doi.org/10.2973/odp.proc.sr.175.236.2001

    Description: The composite depth scale for Holes 1077A and 1077B (Shipboard Scientific Party, 1998) contains imperfections between 115 and 155 meters composite depth (mcd). The spliced magnetic susceptibility record shows discrepancies when compared to the record of Site 1075 at 120-125 and 140-150 mcd (Ocean Drilling Program [ODP] Site 1077 scale) around marine isotope Stages 22 and 34, respectively. In addition, the offsets applied to transform the standard meters below seafloor (mbsf) depths into composite depths cause overlaps between cores of the same hole at the transitions between Cores 175-1077A-12H and 13H, 175-1077B-12H and 13H, and 175-1077B-13H and 14H. These overlaps are supported neither by visual investigation of the lithology in the core photographs (see 'Site 1077 Core Descriptions and Photographs' in Wefer, Berger, Richter, et al., 1998, doi:10.2973/odp.proc.ir.175.1998) nor by the pollen and dinoflagellate content. For these reasons, we have reassessed the Site 1077 composite depth scale.
