PP21B:
Isotopic Tools in Sedimentary Archives: Clues for the Paleo-Detective IV Posters

Submit an Abstract to this Session



Session ID#: 24347

Session Description:
More than ever, the past is the key to the future. As the current ocean-atmosphere system experiences changes at a possibly unprecedented pace, this raises questions of how Earth surface environments will adapt to these new boundary conditions. The scientific community has been looking into the past for decades, aiming at unravelling ancient links between climate, tectonics, life, and landscapes. Isotope geochemistry provides tools to reconstruct such interactions. This session aims at gathering recent advances in the modeling and applications of isotopic proxies in sedimentary archives. Contributions to this session may include a range of timescales from the Anthropocene into the Precambrian.
