- ItemContaminant emissions as indicators of chemical elements in the snow along a latitudinal gradient in southern Andes(NATURE RESEARCH, 2021) Pizarro, Jaime; Vergara, Pablo M.; Cerda, Sergio; Cordero, Raul R.; Castillo, Ximena; Rowe, Penny M.; Casassa, Gino; Carrasco, Jorge; Damiani, Alessandro; Llanillo, Pedro J.; Lambert, Fabrice; Rondanelli, Roberto; Huneeus, Nicolas; Fernandoy, Francisco; Alfonso, Juan; Neshyba, StevenThe chemical composition of snow provides insights on atmospheric transport of anthropogenic contaminants at different spatial scales. In this study, we assess how human activities influence the concentration of elements in the Andean mountain snow along a latitudinal transect throughout Chile. The concentration of seven elements (Al, Cu, Fe, Li, Mg, Mn and Zn) was associated to gaseous and particulate contaminants emitted at different spatial scales. Our results indicate carbon monoxide (CO) averaged at 20 km and nitrogen oxide (NOx) at 40 km as the main indicators of the chemical elements analyzed. CO was found to be a significant predictor of most element concentrations while concentrations of Cu, Mn, Mg and Zn were positively associated to emissions of NOx. Emission of 2.5 mu m and 10 mu m particulate matter averaged at different spatial scales was positively associated to concentration of Li. Finally, the concentration of Zn was positively associated to volatile organic compounds (VOC) averaged at 40 km around sampling sites. The association between air contaminants and chemical composition of snow suggests that regions with intensive anthropogenic pollution face reduced quality of freshwater originated from glacier and snow melting.

- ItemDust archives within polar ice cores(Elsevier, 2024) Lambert, FabriceMineral dust aerosols are pivotal components of Earth's atmosphere and significantly influence the climate system. Investigating their impacts through ice core records offers unique insights into paleoclimate dynamics. Various techniques, including direct and indirect measurements of concentrations and size distributions, unravel the complex story of dust provenance, transport, and deposition. Dust records correlate with temperature reconstructions, reflecting the interconnectedness of climatic processes. Enhanced characterization methods promise a deeper understanding of the role of dust in the Earth's history. The current state of knowledge on paleoclimatic mineral dust in ice cores is reviewed, including its measurement, hemispheric differences, and climatic interpretation.

- ItemEstimating coastal flood hazard of Tossa de Mar, Spain: a combined model - data interviews approach(SPRINGER, 2021) Hernandez Mora, Marina; Meseguer Ruiz, Oliver; Karas, Cyrus; Lambert, FabriceHuman settlements in coastal areas are highly vulnerable to extreme events, especially in the Mediterranean area, which houses a large number of tourists during the summer and autumn months. It is important to carry out hazard studies at local scale to improve our understanding of natural and anthropogenic processes involved in episodes of coastal flooding. We reconstruct and characterize an extreme weather event in Tossa de Mar (northeastern Spain) and the subsequent urban flooding that occurred in 2008. Our results show flood heights up to 1.27 m, with the maximum occurring between 24 and 64 h after the start of the event. This is broadly consistent with the reconstructions obtained through interviews and photographs. Based on model simulations, we produce a hazard map for the town based on hydrodynamic scenarios for different return periods. We show that the southern part of the town is more susceptible to flooding, whereas the northern part is relatively resilient to extreme events. We recommend the adaption of a currently existing dune by adding vegetation and slightly increasing its height. This low economic cost action would significantly reduce flooding and increase resilience in this area.

- ItemPaleo±Dust: quantifying uncertainty in paleo-dust deposition across archive types(2024) Cosentino, Nicolás J.; Torre, Gabriela; Lambert, Fabrice; Albani, Samuel; De Vleeschouwer, François; Bory, Aloys J. M.Mineral dust aerosol concentrations in the atmosphere varied greatly on glacial–interglacial timescales. The greatest changes in global dust activity occurred in response to changes in orbital parameters (which affect dust emission intensity through glacial activity) and the lifetime of dust in the atmosphere (caused by changes in the global hydrological cycle). Long-term changes in the surface dust deposition rate are registered in geological archives such as loess, peats, lakes, marine sediments, and ice. Data provided by these archives are crucial for guiding simulations of dust and for better understanding the natural global dust cycle. However, the methods employed to derive paleo-dust deposition rates differ markedly between archives and are subject to different sources of uncertainty. Here, we present Paleo±Dust, an updated compilation of bulk and <10 µm paleo-dust deposition rates with quantitative 1σ uncertainties that are inter-comparable among archive types. Paleo±Dust incorporates a total of 285 pre-industrial Holocene (pi-HOL) and 209 Last Glacial Maximum (LGM) dust flux constraints from studies published until December 2022, including, for the first time, peat records. We also recalculate previously published dust fluxes to exclude data from the last deglaciation and thus obtain more representative constraints for the last pre-industrial interglacial and glacial end-member climate states. Based on Paleo±Dust, the global LGM:pi-HOL ratio of <10 µm dust deposition rates is 3.1 ± 0.7 (1σ). We expect Paleo±Dust to be of use for future paleoclimate dust studies and simulations using Earth system models of high to intermediate complexity.
