Isotopic tracers and chronometers of climate, ocean and environmental changes in the Arctic/sub-Arctic domains (co-organized)
Convener: Alain Veron  | Co-Conveners: Claude Hillaire-Marcel , Martin Frank 

Research activity about climatic, environmental and paleoceanographic changes in the Arctic Ocean, its surrounding continents and sub-arctic seas, has increased drastically in recent years. Stable, radioactive and radiogenic isotopes provide here a large array of tools to document land-ocean fluxes, atmospheric and oceanic circulation patterns as well as an essential tool for the setting of time series from sedimentary archives. The planned session aims at joining expertise about land processes, dissolved and particulate fluxes towards the Arctic Ocean and surrounding seas, from such isotopic perspectives, with special attention to i) the dating of environment/ocean changes during the Late Quaternary, ii) the identification of eolian/marine sediment sources and their change through time, iii) on-going natural/anthropogenically driven processes and iv) isotopic links between continental/marine and ice time series
