When nitrogen-based fertilizers flow into water bodies, the result can be deadly for marine life near shore, but what is the effect of nitrogen pollution far out in the open ocean?

Hurricane Sandy sent a clear message on climate change, Tammy Snyder Murphy, the first lady of New Jersey, told the audience in her keynote speech at a Princeton climate conference Friday, Sept. 21.
“We’re not looking at Sandy as just some part of our history, but something that we know will happen again unless we take action,” said Murphy, who plays a key role in the governor’s administration on climate and environmental policy. “We are accepting the challenge that climate change has presented. We are committed to making this state the magnet for innovative solutions.”

With the right public infrastructure investment, the United States could as much as double the amount of carbon dioxide emissions currently captured and stored worldwide within the next six years, according to an analysis by Princeton University researchers.

Imagine an enormous volcano erupting in the Pacific Northwest, pouring lava across Washington, Oregon and Idaho. Imagine the lava flooding out until river valleys are filled in. Until bushes and shrubs are buried in liquid rock. Until the tallest trees are completely covered.
About 16 million years ago, this happened.
Lava erupted in pulses, ultimately burying the region to the height of a 30-story building. If the lava had been spread evenly over the lower 48 states instead of staying concentrated in the northwest, it would cover the country to a depth of about 80 feet.

When oceanographer Bess Ward was granted research time aboard the R/V Sally Ride during the middle of the spring semester, she had to figure out how to teach GEO 428, “Biological Oceanography,” from the Pacific Ocean.

Committed to addressing the country’s severe air pollution, China is attempting a shift from coal to natural gas and is considering a variety of sources, including domestic and imported gas options as well as creating its own synthetic gas from coal.
A team of researchers led by Princeton University investigated the environmental impacts of transitioning from coal to natural gas in China, exploring implications on air quality, carbon mitigation and water stress by the year 2020.

The Southern Ocean surrounding Antarctica is regarded by scientists as a large and crucial absorber of carbon dioxide from the atmosphere. New findings from autonomous floats deployed in the Southern Ocean, however, provide the first comprehensive data to suggest that, in winter, the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide into the atmosphere than previously thought.

Hydraulic fracturing, or fracking, provides critical energy for society, but also uses large amounts of fresh water while producing corresponding amounts of wastewater. Water-based foams, which use about 90 percent less water than fracking fluids, provide an alternative, but the mechanism for foam-driven fracture in such drilling is not well understood.

The oceans are the planet’s most important depository for atmospheric carbon dioxide on time scales of decades to millenia. But the process of locking away greenhouse gas is weakened by activity of the Southern Ocean, so an increase in its activity could explain the mysterious warmth of the past 11,000 years, an international team of researchers reports.
