Project description: Methane loss from the Arctic: Towards an annual budget of CH4 emissions from tundra ecosystems across a latitudinal gradient – Zona, Oechel, Lipson
Significance of the proposed project
Permafrost soils contain a huge amount of C, about 30-50% of the global belowground organic carbon pool (Schuur et al., 2008; Kuhry et al., . . . → Read More: Methane loss from the Arctic: towards an annual budget of CH4 emissions from tundra ecosystems across a latitudinal gradient

Abstract: Partial pressure of CO2 in equilibrium with sample water (pCO2) for the coastal water in the Chukchi Sea was continuously observed in summer, 2008. Average daily CO2 flux calculated from the pCO2 and gas transfer coefficients ranged from -0.144 to -0.0701 g C . . . → Read More: Air-sea CO2 exchange of beach and near-coastal waters of the Chukchi Sea near Barrow, Alaska
“Although many scientists agree that the current warming trend is likely to continue, it is unknown whether a warmer climate will turn the Arctic Coastal Plain from a sink to a source of greenhouse gases…. Cove Sturtevant and Dr. Walt Oechel from San Diego State University in California are addressing some of these questions . . . → Read More: GCRG on LI-COR NewsLine: Measure Methane Where it Matters: Part II, Barrow, Alaska
GCRG was awarded a grant by the US Department of Energy for the proposal, “Seasonal and Inter-Annual Controls on CO2 Flux in Arctic Alaska” (PI: Walt Oechel). The grant will allow GCRG to operate eddy covariance flux towers at Barrow, Atqasuk and Ivotuk for the next 3 years.

GCRG will work with the National Aeronautics and Space Administration’s Jet Propulsion Lab to measure the greenhouse gas effect on the Arctic. The research team will collect data that will provide unprecedented experimental insights into Arctic carbon cycling, especially the release of the important greenhouse gases such as carbon dioxide and methane. The study . . . → Read More: GCRG Heads for the Skies with NASA-Funded Research
The 17th Annual Albert W. Johnson University Research Lecture Walter C. Oechel, Ph.D. “Global Change: Is the World Beyond Repair?”
March 21, 2007 | 3:00-4:30pm | Aztec Athletic Center Auditorium
Recently, it was another beautiful, sunny day out on the Arctic tundra. Scientists say the Arctic is melting — and fear it could help send Earth into a global warming tailspin. It may sound nicer that way — but it’s a big problem for the Earth. Scientists say the warm weather adds to global . . . → Read More: What is a “Feedback Loop?”: Dr. Oechel on ABC News
Tidal waves, tornadoes, and the big freeze. The Day After Tomorrow is the latest disaster movie to hit the big screen. But how much of it is based on fact? We’ll talk about the realities of global warming.
