Goldschmidt 2017 – Organic Geochemistry of the Anthropocene

Chers collègues,

Avec Jagos Radovic, Christopher Reddy, et Nathalie Dubois, nous proposons une session (11i) intitulée « Organic Geochemistry of the Anthropocene – From Stratigraphy to Earth System » à la Goldschmidt 2017 qui aura lieu à Paris.

La soumission des résumés est ouverte depuis le 1er janvier 2017 jusqu’au 1er avril.

Cordialement,

Jérémy

The Anthropocene has recently been proposed as a new geological epoch, in which human activities, such as the burning of fossil fuels, plant cultivation, soil erosion, and others, have modified the natural cycles of organic matter (OM). In addition to perturbing the cycling of natural OM and compounds, human activities released large quantities of diverse synthetic materials into the environment, which constitute multiple threats. The evolution of these complex transitions, since prehistory to the great industrial acceleration of the modern era, are reflected in equally intricate (bio)geochemical signals. In this session, we welcome contributions that address the source, fate, history, and ecosystem impacts of OM perturbations and compounds (natural and synthetic) that were released in the geological realm by human activities. In this context, showcases of novel, multidisciplinary approaches are particularly encouraged. The objective is to gather a diverse group of researchers, including archaeologists, paleoenvironmentalists, microbiologists, environmental geochemists, and others, who study the anthropogenic impacts in various media, and across temporal scales, using bulk, elemental, isotopic and molecular analyses. The session will aim to reevaluate the established (bio)geochemical concepts in relation to global change, and discuss possible solutions to alleviate the major environmental challenges presented by the Anthropocene.
