(2020) Abundant nitrite oxidoreductase metalloenzyme in the mesopelagic metaproteome of Pacific OMZ extremities. (In Review) Overturning circulation, nutrient limitation, and warming in the Glacial North Pacific. Scripps Institution of Oceanography (with Chris Charles) Princeton University (with Danny Sigman and Gerald Haug) We need to use these "proxy" records because our ocean observations are not long enough to show significant changes associated with the current buildup of greenhouse gases. Number (1) takes me out onto the ocean to make measurements and collect seawater samples and (2) is accomplished using a variety of geological archives such as ocean sediments and corals. (2) by reconstructing past ocean conditions that help reveal the inner workings of planetary processes. (1) by studying the "natural" variability of modern ocean biology, chemistry, and physics that guide the air-sea partitioning of carbon dioxide My work seeks to identify, better understand, and ultimately predict these future changes in two general ways: Bachelor of Arts in Environmental ScienceĪlso see: The modern increase of greenhouse gases (such as carbon dioxide) will affect our oceans and climate in sometimes dramatic and unexpected ways.īut it doesn't have to be entirely unexpected!.Bachelor of Science in Earth System Science.FAQs for the Earth System Science (ESS) Graduate Program.Cicerone Endowed Chair and Fellowship Fund in Earth System Science
