Diving robots find that Antarctic seas release surprising amounts of carbon dioxide in winter

Publish Date: 
Tuesday, August 14, 2018 - 12:00pm

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.

Photosynthesis and engines evolved in remarkably similar ways

A study from the group of Amilcare Porporato, the Thomas J. Wu ’94 Professor of Civil and Environmental Engineering and the Princeton Environmental Institute, suggests that plants and internal combustion engines share striking parallels in adapting to changing environmental conditions. The study suggests that people could more consciously take lessons from nature when designing mechanical systems.

Ocean's heat cycle shows that atmospheric carbon may be headed elsewhere

Publish Date: 
Tuesday, June 19, 2018 - 12:30pm

A Princeton University-led study in the journal Nature Geoscience examined the global carbon cycle and suggests that scientists may have misgauged how carbon is distributed around the world, particularly between the northern and southern hemispheres. The results could change projections of how, when and where the currently massive levels of atmospheric carbon will result in environmental changes such as ocean acidification.

Call for Proposals: PEI Urban Grand Challenge

Publish Date: 
Friday, June 15, 2018 - 10:30am

The Princeton Environmental Institute is accepting faculty proposals for two-year projects of up to $150,000 for the Urban Grand Challenge program through Friday, June 29, 2018. Part of PEI's Grand Challenges program, the Urban Challenge combines the study of natural and built environments to address the interrelated environmental and social issues that face the world's rapidly expanding urban areas in an era of increasing environmental volatility.
