title: Tab. 1 + 2: Distribution chart of nannoplankton species record

description: Between March and April of 1986 a series of water samples were taken in the South Atlantic to study the Recent calcareous nannoplankton assemblages in that part of the world. South of Africa, in the transitional floral zone, most of the coecolithophorid flora elements characteristic of this zone were recognized but in addition influences from the floras of the Indian Ocean were distinguished as well as floral elements belonging to the tropical and subtropical floral zones. It is concluded that the transitional floral zone should be redefined on the basis of seasonal changes of the assemblages. In the cold waters between the Subtropic and the Antarctic Convergences near the Antarctic continent, calcareous nannoplankton is scarce. Only a monospecific assemblage of malformed Emiliania huxleyi was found. Probably the combination of cold water and high hydro energy levels prevents the development of adiverse coccolith-bearing nannoplankton assemblage. South of the Antarctic Convergence no calcareous nannoplankton was found.

title: (Table 1) Elemental composition of benthic foraminifera from South Atlantic core top samples

description: The ocean plays a major role in the global carbon cycle, and attempts to reconstruct past changes in the marine carbonate system are increasing. The speciation of dissolved uranium is sensitive to variations in carbonate system parameters, and previous studies have shown that this is recorded in the uranium-to-calcium ratio (U/Ca) of the calcite shells of planktonic foraminifera. Here we test whether U/Ca ratios of deep-sea benthic foraminifera are equally suited as an indicator of the carbonate system. We compare U/Ca in two common benthic foraminifer species (Planulina wuellerstorfi and Cibicidoides mundulus) from South Atlantic core top samples with the calcite saturation state (Delta [CO3**2-] = [CO3**2-]in situ - [CO3**2-]sat) of the ambient seawater and find significant negative correlations for both species. Compared with planktonic foraminifera, the sensitivity of U/Ca in benthic foraminifera to changes in Delta [CO3**2-] is about 1 order of magnitude higher. Although Delta [CO3**2-] exerts the dominant control on the average foraminiferal U/Ca, the intertest and intratest variability indicates the presence of additional factors forcing U/Ca.

title: Modern major element concentrations and ratios measured in Atlantic surface sediments (36°N-49°S)

description: Numerous studies use major element concentrations measured on continental margin sediments to reconstruct terrestrial climate variations. The choice and interpretation of climate proxies however differ from site to site. Here we map the concentrations of major elements (Ca, Fe, Al, Si, Ti, K) in Atlantic surface sediments (36°N-49°S) to assess the factors influencing the geochemistry of Atlantic hemipelagic sediments and the potential of elemental ratios to reconstruct different terrestrial climate regimes. High concentrations of terrigenous elements and low Ca concentrations along the African and South American margins reflect the dominance of terrigenous input in these regions. Single element concentrations and elemental ratios including Ca (e.g., Fe/Ca) are too sensitive to dilution effects (enhanced biological productivity, carbonate dissolution) to allow reliable reconstructions of terrestrial climate. Other elemental ratios reflect the composition of terrigenous material and mirror the climatic conditions within the continental catchment areas. The Atlantic distribution of Ti/Al supports its use as a proxy for eolian versus fluvial input in regions of dust deposition that are not affected by the input of mafic rock material. The spatial distributions of Al/Si and Fe/K reflect the relative input of intensively weathered material from humid regions versus slightly weathered particles from drier areas. High biogenic opal input however influences the Al/Si ratio. Fe/K is sensitive to the input of mafic material and the topography of Andean river drainage basins. Both ratios are suitable to reconstruct African and South American climatic zones characterized by different intensities of chemical weathering in well-understood environmental settings.
