title: n-alkane carbon and hydrogen stable isotope data from sediment core M125-95-3

description: In order to assess the response of vegetation from eastern tropical South America to hydroclimate changes during the last ca. 45 kyr, we analyzed marine sediment core M125-95-3 that archived sediments from the São Francisco River drainage basin. We used the stable carbon (δ13C) and hydrogen (δD) isotopes of long-chain n-alkanes (i.e., C29-C31) to reconstruct regional vegetation composition and precipitation dynamics, respectively. The data set contains marine sedimentary records of long-chain n-alkane δ13C and δD, as well as the isotopic difference between homologues (Δδ13C31-29), and locally estimated scatterplot smoothing (LOESS) of indicated data. The δ13Cwax refers to the weighted averages of δ13C29 and δ13C31 values. The δDwax refers to the weighted averages of δD29 and δD31 values.

title: Pigment concentration database of the sea surface layer collected during the Tara Pacific Expedition 2016-2018

description: The Tara Pacific expedition (2016-2018) sampled coral ecosystems around 32 islands in the Pacific Ocean, and sampled the surface of oceanic waters at 249 locations, resulting in the collection of nearly 58,000 samples. The expedition was designed to systematically study corals, fish, plankton, and seawater, and included the collection of samples for advanced biogeochemical, molecular, and imaging analysis. Here we provide a pigment concentrations database originating from 545 stations sampled during the expedition. Pigment were measured by High Performance Liquid Chromatography. This pigment database provides high quality measurements of the major taxonomic pigments including chlorophylls a, b and c, peridinin, 19'-butanoyloxyfucoxanthin, fucoxanthin, neoxanthin, prasinoxanthin, violaxanthin, 19'-hexanoyloxyfucoxanthin, diadinoxanthin, antheraxanthin, alloxanthin, diatoxanthin, zeaxanthin, lutein, divinyl chlorophyll b, chlorophyll b, divinyl chlorophyll a, chlorophyll a, carotene and bacteriochlorophyll a, which can be used to estimate phytoplankton community composition.

title: (Table 1) Lipid biomarkers in surface sediments from the Gulf of Genoa

description: A series of molecular organic markers were determined in surface sediments from the Gulf of Genoa (Ligurian Sea) in order to evaluate their potential for palaeo-environmental reconstructions. Allochthonous input can be characterized by the distributions of n-C29 and n-C31 alkanes, n-C26 and n-C28 alkanols and branched glycerol dialkyl glycerol tetraethers (GDGTs), whose concentrations are generally highest near the river mouths. In the open basin however, terrestrial n-alkanes and n-alkanols may have an additional, aeolian source. Autochthonous input is represented by crenarchaeol and isoprenoid GDGTs. Their concentrations are highest in the open basin showing the preference of Thaumarchaeota for oligotrophic waters. Indications of a significant degradation of sterols and C37 alkenones exclude these lipids as reliable productivity proxies. Using terrestrial and aquatic lipids as end-members allows estimating the percentage of terrestrial organic matter between 20% and 58% in the coastal area decreasing to 1 to 30% in the deep basin. The spatial distribution of sea surface temperature (SST) estimates using the alkenone-based UK'37 index is very similar to the autumnal (November) mean satellite-based SST distribution. Conversely, TEXH86-derived SST estimates are close to winter SSTs in the coastal area and summer SSTs in the open basin. This pattern reflects presumably a shift in the main production of Thaumarchaeota from the coastal area in winter to the open basin in summer. This study represents a major prerequisite for the future application of lipid biomarkers on sediment cores from the Gulf of Genoa.

title: Pliocene stable carbon and hydrogen isotopes of plant wax of ODP Site 108-659

description: The Pliocene is regarded as a potential analogue for future climate with conditions generally warmer-than-today and higher-than-preindustrial atmospheric CO2 levels. Here we present the first orbitally resolved records of continental hydrology and vegetation changes from West Africa for two Pliocene time intervals (5.0-4.6 Ma, 3.6-3.0 Ma). Our results indicate that changes in local insolation alone are insufficient to explain the full degree of hydrologic variations. Generally two modes of interacting insolation forcings are observed: during eccentricity maxima, when precession was strong, the West African monsoon was driven by summer insolation; during eccentricity minima, when precession-driven variations in local insolation were minimal, obliquity-driven changes in the summer latitudinal insolation gradient became dominant. This hybrid monsoonal forcing concept explains orbitally-controlled tropical climate changes, incorporating the forcing mechanism of latitudinal gradients for the Pliocene, which probably increased in importance during subsequent Northern Hemisphere glaciations.

title: Microfossil census counts from a Holocene sediment core obtained southwest off the Cabo Verde archipelago (MUC5)

description: This dataset provides absolute abundance data of planktonic foraminifera (identified at the species level), benthic foraminifera and radiolaria (both counted as total numbers). The microfossils were obtained from a sediment core collected at 4394 m water depth off the Cabo Verde archipelago which covers most of the Holocene Epoch. Counts were performed on the &gt;150 µm sediment fraction, with a minimum of 300 planktonic foraminifera specimens per sample.

title: Plant-wax isotope values of sediment core GeoB16224-1

description: Variations in Amazonian hydrology and forest cover have major consequences for the global carbon and hydrological cycles as well as for biodiversity. Yet, the climate and vegetation history of the lowland Amazon basin and its effect on biogeography remain debated due to the scarcity of suitable high-resolution paleoclimate records. Here, we use the isotopic composition (dD and d13C) of plant-waxes from a high-resolution marine sediment core collected offshore the Amazon River to reconstruct the climate and vegetation history of the integrated lowland Amazon basin for the period from 50,000 to 12,800 yr before present. Our results show that dD values from the Last Glacial Maximum were more enriched than those from Marine Isotope Stage (MIS) 3 and the present-day. We interpret this trend to reflect long-term changes in precipitation and atmospheric circulation, with overall drier conditions during the Last Glacial Maximum. Our results thus suggest a dominant glacial forcing of the climate in lowland Amazonia. In addition to previously suggested thermodynamic mechanisms of precipitation change, which are directly related to temperature, we conclude that changes in atmospheric circulation are crucial to explain the temporal evolution of Amazonian rainfall variations, as demonstrated in climate model experiments. Our vegetation reconstruction based on d13C values shows that the Amazon rainforest was affected by intrusions of savannah or more open vegetation types in its northern sector during Heinrich Stadials, while it was resilient to glacial drying. This suggests that biogeographic patterns in tropical South America were affected by Heinrich Stadials in addition to glacial-interglacial climate variability.
