Molecular distribution and isotopic composition (δD and δ(13)C) of lipids dataset for a sediment core (GeoB16202-2) from the north-eastern Brazilian margin
The distribution and isotopic composition (δ(13)C and δD) of lipids are proxies used to determinate paleoenvironmental conditions including precipitation regimes, vegetation changes and sources of organic matter, among others. This data article describes five datasets of distribution (n-alkanes, fat...

description | The distribution and isotopic composition (δ(13)C and δD) of lipids are proxies used to determinate paleoenvironmental conditions including precipitation regimes, vegetation changes and sources of organic matter, among others. This data article describes five datasets of distribution (n-alkanes, fatty acids, n-alkanols and sterols) and isotopic composition (n-alkanes and fatty acids) of lipids determined in 50 samples from a gravity core (GeoB16202–2) retrieved on the continental slope off northeastern Brazil. The core site is influenced by the Parnaiba freshwater discharge, the North Brazil Current and by the Intertropical Convergence Zone (ITCZ). Previous work focused on inorganic proxies in this core revealed important clues of climatic conditions during the Heinrich Stadial 1 (HS1). The baseline dataset of molecular and isotopic proxies of the organic matter provided here are additional and/or complimentary evidences to help elucidate past climate change during the Quaternary in the Equatorial Atlantic, where less information is available in comparison to other regions in this ocean. |
