    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

    Beschreibung: 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.

    Beschreibung: The data set contains lipid biomarker and bulk organic matter data from two sediment cores in the Shaban Deep, in the northern Red Sea. One core is deposited in the hypersaline brine (GeoB7805-1 2) and the other core (GeoB7807-2) is deposited outside the brine. The data set compares the lipid biomarker signals in the two deposition settings. For both cores the data set contains total organic carbon data, total nitrogen data, bulk organic matter carbon and hydrogen isotope data, long-chain n-alkane concentrations, alkenone concentrations, long- and short-chain fatty acid concentrations, long-chain n-alkane and long-chain fatty acid average chain length and carbon preference index data, UK37 data, stable carbon and hydrogen isotope data for long-chain n-alkanes, alkenones, and long- and short chain fatty acids.
