UCI researchers: carbon in Earth’s soil older than previously thought
Analyzing radiocarbon dating on a massive database of soil samples from around the world, University of California, Irvine researchers have determined that globally, the average age of the carbon in the ground is about 5,000 years old. In a study published today in Nature Geoscience, a team led by Zheng Shi, UCI postdoctoral scholar in […]
UCI scientists analyze first direct images of dissolved organic carbon from the ocean
Joint research project furthers understanding of important CO2 reservoir
Soil will absorb less atmospheric carbon than expected this century, UCI-led study finds
Improved Earth system models paint bleak climate change picture
Down to the bones
UC Irvine researchers sort out the sticky situation at the La Brea Tar Pits by refining methods for measuring the age of fossils
Little black carbon reaches ocean floor, study finds
Just a fraction of the carbon that finds its way into Earth’s oceans–the black soot and charcoal residue of fires–stays there for thousands of years. A first-of-its-kind analysis by UC Irvine, Rice University and the University of Southern California also revealed how some black carbon breaks away and hitches a ride to the ocean floor on passing particles.
Perfect chemistry for 30 years
A conversation with 30-year collaborators F. Sherwood Rowland and Donald Blake.
Perfect chemistry
The first person Donald Blake met when he walked into UC Irvine’s chemistry department in 1978 was F. Sherwood Rowland, clad in shorts and sandals, a towering 6 feet 5 inches tall. Rowland, department chair, was considering the UCLA senior for a graduate position. “We talked about lots of things, and in the end […]
