An Archive of Glacial Seawater and Implications for Carbonate Platform Sediments
Seds Online via YouTube
Overview
Explore the groundbreaking discovery of ancient seawater preserved in pore fluids extracted from sediment cores in the Maldives Inner Sea. Delve into the implications of this finding for understanding glacial ocean circulation, water-rock interaction in carbonate platforms, and the preservation of sedimentary geochemistry. Learn about the unexpected chloride signal, tracers, and paleontographic implications of this unique archive from the Last Glacial Maximum. Examine how this discovery impacts our understanding of global salinity and carbonate records. Gain insights into the factors affecting carbonate records, including temperature and salinity, and their significance in reconstructing past oceanic conditions.
