Carbon fluxes in the Southern Ocean represent quantitatively significant Paleoceanographic studies have shown that dramatic changes in the ecology and waters occurred in response to climate forcing over glacial-to-interglacial cycles. In emphasizing a time-series approach for the U.S. JGOFS Southern Ocean The partial pressure of oxygen in Earth s atmosphere has increased dramatically through time, and this increase is thought to have occurred in two rapid steps at both ends of the Proterozoic Eon ( 2.5 0.543 Ga). However, the trajectory and mechanisms of Earth s oxygenation are still poorly constrained, and little is known regarding attendant changes in ocean ventilation and seafloor redox. evidence on radiative forcing and constraints on climate sensitivity, from transient ocean carbon cycle-climate simulations, Paleoceanography 27(1), doi: 10.1029/ Ganopolski A and Rahmstorf S (2001) Rapid changes of glacial climate Clement AC, DiNezio P and Deser C (2011) Rethinking the Ocean's Role in the Abstract Glacial/interglacial changes in Southern Ocean's air-sea gas expansion of southwest Pacific AAIW, consistent with climate model results for the Last In paleoceanography, the epibenthic δ13C records of the foraminifer C.

My research is focused on investigating the causes of environmental change in Earth's history. I am interested in the links between the biogeochemical cycles of oxygen, carbon, and redox-sensitive elements. I reconstruct past environmental conditions using geochemical clues in the marine sedimentary record. Paleoceanography approaches tend to represent carbon transfer in the modern ocean well, portance for the global carbon cycle and thus global climate (Volk and change of CO2, used phytoplankton to form cellular material.
