Blue Planet: Introduction to Oceanography

About The Professor


Edwin Schauble is an Associate Professor from UCLAs Department of Geochemistry and Astrobiology. His current area of study and collaboration include species-dependent isotopic signatures in dissolved iron, spectroscopic signatures and thermodynamic properties of dissolved silica, non-mass dependent isotopic fractionation in heavy elements, calibration of the 13C-18O clumping paleothermometer, and the possibility of silicon as an alloying element in the Earths core.



Current Research Interests

Geochemistry: Computational chemistry and electronic structure modeling of natural materials and pollutants. Stable isotope fractionation theory. Development of new proxies for ancient climates and environmental conditions. Equilibrium isotope separation at high pressures and temperatures.



Current areas of study and collaboration include species-dependent isotopic signatures in dissolved iron, spectroscopic signatures and thermodynamic properties of dissolved silica, non-mass dependent isotopic fractionation in heavy elements, calibration of the 13C-18O “clumping” paleothermometer, and the possibility of silicon as an alloying element in the Earth’s core.
