Preservation of δ13C signatures in oak charred wood: Application to the “forest” of Notre-Dame de Paris
The fire of the Notre-Dame de Paris’s cathedral (NDP) in 2019 brought a unique opportunity to study the past environmental conditions in the region during the High Middle Ages through the charred oak beams of the “Forest” (name given to its framework). However, as a preamble, there is a need to evaluate the preservation of the stable carbon isotope signatures (δ13C) in response to changes in molecular composition, occurring with carbonisation. To…
Hydroclimate reconstruction during the last 1000 years inferred from the mineralogical and geochemical composition of a sediment core from Lake-Azuei (Haiti)
This study aims to reconstruct the hydro-climatic variations over the last 1000 years in Haiti using mineralogical and geochemical composition of well dated lacustrine sediment core retrieved from Lake Azuei. The results show changes in sedimentological processes linked to environmental and climatic variations. The general pattern suggests a wetter Medieval Climate Anomaly (MCA), drier Little Ice Age (LIA), high climate variability during the MCA…
Diatom-based paleoproductivity and climate change record of the Gulf of Tehuantepec (Eastern Tropical Pacific) during the last ~500 years
Changes in marine productivity of the last five centuries in the Gulf of Tehuantepec were investigated using a high-resolution record of diatoms, organic carbon (C org ), total nitrogen (TN), Ni/Al, and Cu/Al. The laminated sediments were dated by using 210 Pb and 14 C, with a bayesian age model providing a new Δ R = 247 ± 30 years for the bulk sediment. The Little Ice Age (LIA) (~1500 to ~1858 CE) was characterized by the predominance of cold-wa…
