Sept. 26: The Field & Berry Lab Group met at noon to discuss plans for the Fall Quarter. It was decided to continue meeting weekly at this hour with members of the group discussing their current or planned research interests. Four new graduate students were introduced. Chris Field described a Workshop on Biofuels in Germany from which he had just returned. He also described the IPCC Meeting in Geneva when he was elected Co-Chair of Working Group 2 mentioned above. The Stanford Report of Sept. 24 describes what both Stanford and Carnegie may expect from Chris' leadership in this international organization during the next five years. His Co-Chair is Vicente Barros of Argentina. |

| Oct. 8: Dr. Sharachchandra Lélé, Senior Fellow and Coordinator, Centre for Interdisciplinary Studies in Environment and Development in Bangalore, talked about Forest Cover Change, Hydrological Services and Economic Impact: Findings from the Western Ghats, India. He spoke about trade-offs between forested areas and | |||||||||||||||||||||||||||||||

| crop lands with regard to water, energy, erosion, sediment, peak flows (floods), ground water recharge and water quality. His studies have shown that the changes/differences in infiltration rates caused by changes/differences in forest condition show up at different scales and may even change sign depending upon the socio-technical context. | |||||||||||||||||||||||||||||||
| Oct. 15: Dr. Aradhuna Tripati, NERC Fellow in the Dept. Earth Sciences, Univ. Cambridge & Visiting Fellow in the Geological & Planetary Sciences Div., Calif. Inst. Technology spoke on Using the geologic record to probe climate-carbon cycle interactions. She outlined the | ![]() |

| various methods for measuring pH & CO2 in the distant past using sea shells among others. One conclusion is that during the last 600 million years, climate has been internally controlled by CO2, not by cosmic rays (as some have thought). This seminar was used as a trial run for video recording future talks and adding them to the DGE Web Site. |

Outreach

| Oct. 1: Chris Field spoke about Bioenergy and Bio Conversion at the 5th Annual Global Climate & Energy Project (GCEP) Research Symposium held in the Arrillaga Alumni Center at Stanford, Oct. 1-3. On the second day, Chris chaired a session on Biofuels and Bioenergy Conversion during which Scott Loarie spoke on Biomass Energy: The Climate-Protective DomainAnalytical Models and Techniques. Luis Fernandez has been in Peru for a recent three weeks serving as Technical Director of an EPA/Argonne National Laboratory project under partnership with UNEP, to study mercury cycling through Amazonian watersheds. So far, at two study sites, they have found very high levels of both elemental mercury and aerosols in air and methylmercury in high-trophic-level fish species that were correlated with upstream artesinal scale gold mining. They also hope to develop intervention measures to reduce mercury releases by use of a simple mercury condenser system developed by the Argonne Lab that reduces airborne Hg releases in rustic mining operations by 85%. |

Asner Group

| This month, the Group welcomes two new Post Docs, Chris Doughty & Shaun Levick as well as recent and ongoing visitors: Angela de Santis & Jolene Fisher. Greg & Robin Martin, with an Aussie team, were in northern Australia's Wet Tropics Eco-region for three weeks to collect leaf samples from rain forest tree species. Oct. 22: Greg reports "We just completed the second Spectranomics field campaign throughout the Wet Tropics World Heritage Area and Cape York in northern Queensland, Australia. These rainforests provided us with access to 25-45 m tall trees representing the greater New Guinea/Oceania ecoregion."

| Choy (Cho-ying Huang) recently returned to Taiwan to his position as Assistant Professor in the Dept. of Geomatics at the National Cheng Kung Univ. He sent photos of his Campus that you may view at http://picasaweb.google.com/choyhuang Oct. 8: David Lobell gave a Seminar in Stanford's new, very green building (Y2E2) about his on-going research titled Prioritizing Investments in Food Security under a Changing Climate. He is identifying food crops which are most sensitive to climate. So far it seems as if many crops are more affected negatively by warmer weather than by decreased rainfall. To adapt a crop genetically to a change in climate takes about 15 yrs. Therefore, it's necessary to do this research now before the anticipated changes occur. |

DGE Picnic 2008
|

| The Annual Picnic was held on a lovely, sunny, Saturday, Oct. 25 from 2 to 5 PM. Good fellowship, food and music were enjoyed by over 40 people. Yuka, Chris A. Roland, KT & Chris D. were among the people who helped Chris F. put it all together. Marion O's piano supplemented the band while we ate a marvelous array of | |||||||||||||||||||||||||||||||
| goodies. If you look closely, you may view the new DGE dark green T-shirts designed & ordered by Adam Wolf. | ![]() |
