CAREER: Calibrating selenium isotopes as tracers of nutrient and redox dynamics in past an — NSF Award to Duke University (NC, $48
Selenium is a common trace element found in seawater and sediments. It has six stable isotopes whose ratios allow it to track oxygen content and biochemical reactions in seawater. So far, Selenium isotopes have proven difficult to measure accurately due to their low concentration. This project will develop new methods

| Abstract | Selenium is a common trace element found in seawater and sediments. It has six stable isotopes whose ratios allow it to track oxygen content and biochemical reactions in seawater. So far, Selenium isotopes have proven difficult to measure accurately due to their low concentration. This project will develop new methods to measure Selenium isotopes. Water samples taken along a profile across the Eastern Pacific Ocean and from sediments in the Black Sea will be used. These samples have very low oxy |
