The late Miocene carbon shift (~6.2 Myr) -a 0.5-1.0 per mil, d13C decrease in benthic and planktonic foraminifera- has been ascribed to changes in global inventory, deep-ocean circulation, and/or productivity. Cadmium, d13C, and nutrients in the ocean are linked; comparison of d13C and Cd/Ca yields...
