  Information - SSP14/CL44 Palaeoceanographic and palaeoclimatic change during the Palaeozoic, Mesozoic and Cenozoic: sedimentological, palaeontological, geochemical and modelling perspectives (co-organized by CL; co-sponsored by IAS)

Event Information
The aim of this session is to bring together sedimentologists, palaeontologists, stratigraphers, geochemists, palaeoceanographers and palaeoclimatologists, to demonstrate how multiple proxies can be applied to Phanerozoic sedimentary successions, to document, quantify and model major shifts and perturbations in the Earth System, particularly in relation to climate change.
The combination of sedimentological and palaeontological proxies with oxygen and carbon stable-isotope records has proven to be a powerful tool in advancing our understanding of palaeoclimate and other palaeoenvironmental change through the Palaeozoic, Mesozoic and Cenozoic. However, most records of Phanerozoic environmental change remain largely qualitative.
Considerable scope now exists for improved quantification and modelling by employing a multi-proxy approach that incorporates traditional sedimentological and palaeontological approaches with newly developed geochemical methods, including: (1) improved palaeotemperature, palaeoclimate and sea-level change records employing Sr, Mn, Mg/Ca and Sr/Ca ratios; productivity proxies using P, Ba, and Cd/Ca ratios; (2) B, Ca, Ge, Li, Mg, Os and Si isotopes to assess variables including palaeoclimate, palaeo-pH, and hydrothermal versus continental weathering fluxes; Nd isotopes to trace ancient water masses; (3) applications of the TEX86 palaeotemperature proxy; C and N isotope studies of biomarkers to devolve terrestrial and marine records of carbon cycle perturbations; biomarker distributions in deep ocean sediments as indicators of photic zone anoxia.
Contributions are sought on all aspects of multi-proxy analysis of Phanerozoic palaeoenvironmental change. Oceanic anoxic events, periods of marked biotic turnover and extinction, and episodes of rapid regional to global climate change, are of particular interest.
