Noah Planavsky Department of Geology and Geophysics, Yale University "Organic and carbonate carbon burial through Earth’s history"
This talk will provide a new framework for interpreting global carbon isotope mass balance through time, highlighting links between atmospheric oxygen and the isotopic composition of the carbon input to the ocean-atmosphere system.
Noah Planavsky has been at Yale for three and half years and is currently the co-director of the Yale Metal Geochemistry Center. He studies the connections between the evolution of Earth-system processes, biological innovation, and ecosystem change—foremost in Earth’s early history. His research integrates field, petrographic, and geochemical work. The protracted rise of oxygen over several billion years dramatically changed Earth’s surface environments. However, our current picture of Earth’s redox evolution is still painted with only broad strokes. A central theme of Noah's research has been trying to piece together the history and effects of Earth’s oxygenation. With that end goal in mind, he is currently working on coupling paleoredox proxies in Precambrian sedimentary rocks, calibrating novel metal isotopes systems in modern aqueous systems, and untangling the distribution and diagenetic history of traces metals in sedimentary rocks.
