The Southern Ocean surrounding Antarctica — regarded by scientists as a large and crucial absorber of atmospheric carbon dioxide — may in fact release significantly more carbon dioxide than previously thought during the winter, according to a study from the Princeton University-based Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project administered by PEI. The study is based on data from autonomous floats deployed by SOCCOM that captured the first comprehensive data about the Southern Ocean during the treacherous Antarctic winter.

Foam could offer greener option for petroleum drillers

Princeton researchers have experimentally tested the fracturing behavior of foam for use in hydraulic fracturing, which would use about 90 percent less water than fracking fluids, but the mechanism for foam-driven fracture is not well understood. The research was supported by PEI's Mary and Randall Hack ’69 Graduate Fund and Carbon Mitigation Initiative and led by PEI associated faculty Howard Stone, the Donald R. Dixon '69 and Elizabeth W. Dixon Professor of Mechanical and Aerospace Engineering.
