9415991 Lea This project will continue experimental culturing of planktic foraminifera to determine the biogeochemistry of stable isotopes and trace elements incorporated in the shell. This kind of data is widely used by people who reconstruct past ocean circulation and chemistry from marine microfossils, and yet many of the assumptions about the controls on shell chemistry have never been tested. ***
