Comparison of Glacial and Interglacial Oceanographic Conditions in the South Atlantic from Variations in Calcium Carbonate and Radiolarian Distributionsc
Temperature estimates produced by a radiolarian-based transfer function, factor distributions of radiolarian assemblages, and variations in calcium carbonate were used to reconstruct the oceanographic conditions in the South Atlantic during the last glacial maximum (18,000 yr B.P.). This study sugge...
