Session 1 details (OS09)

Section OS – Ocean Sciences 
Session Title: Geochemical and Isotopic Proxies Deciphering Past Environmental and Oceanographic Changes


Main Convener(s): Dr. Selvaraj Kandasamy (Academia Sinica, Taiwan).


Co-convener(s): Dr. Nagender Nath Bejugam (National Institute of Oceanography, India). Dr. Madhavaraju Jayagopal (Universidad Nacional Autonoma de Mexico, Mexico). Dr. Shuh-Ji Kao (Academia Sinica, Taiwan ).


Session Description

Earth System Scientists and Marine Geochemists are interested in reconstructing the past environmental and oceanographic changes over the orbital to millennial timescales by using solid-phase geochemical proxies. Geochemical proxy data for paleoenvironmental and paleoceanographic changes could have large uncertainties, and thus this decade has witnessed the invention of several new proxies, catalyzing a renaissance of sediment geochemical research especially from South and East Asian regions. This session focuses on the advances made in using elemental and isotopic proxies for the past environmental and oceanographic changes in the low- and mid-latitude regions. We welcome contributions related to the critical evaluation of climate-environmental-specific proxies in modern and ancient terrestrial, lacustrine and oceanic environmental settings.

Session Title: Weathering Studies in Asia: Geochemical and Clay Mineralogical Constraints from Modern and Ancient Sediments


Main Convener(s): Dr. Nagender Nath Bejugam (National Institute of Oceanography, India).


Co-convener(s): Dr. Selvaraj Kandasamy (Academia Sinica, Taiwan). Dr. Madhavaraju Jayagopal (Universidad Nacional Autonoma de Mexico, Mexico).


Session Description


The Earth’s Critical Zone and associated terrestrial life is governing by two interdependent surface processes, namely erosion and weathering. A combination of atmospheric carbon dioxide levels and continental weathering intensity controls the Earth’s climate on glacial-interglacial timescales. Recent chemical weathering investigations from East Asia , although only a few, reveal a wide range of chemical weathering conditions that were not previously known. Given the importance of diverse climatic and tectonic regimes in Asia , this session explores the recent advances in chemical weathering using geochemical and clay mineralogical studies of river, lake and ocean sediments, including sedimentary rocks. Chemical weathering studies from oceanic islands, in-land lake systems and comparison between large and small river systems in Asia are most welcome. This session further evaluates the unexplored potential geographical regions for future investigations.
