Measurements (elemental and isotope biogeochemistry, visible range spectroscopy, loss on ignition) were performed on discrete sediment samples and extend back to the late 1800s. Ages were estimated using Pb-210 dating and Bayesian age-depth modeling.-97.40388919.410556Lake Alchichica, Puebla, MexicoFonds de la Recherche Scientifiquehttps://doi.org/10.13039/501100002661PDR T.0079.21Holocene Mexican Crater Lakes and Climate (HolMeCl)
