DGE Newsletter, October 2006
Field Lab
Seminar 10-25-06
The plan for this quarter (Wednesdays at 1 p.m.) will be to learn about the risk of future large carbon losses from vulnerable stocks. Each week we shall focus on a different potentially vulnerable stock.
Oct. 4: Discussion of the vulnerability of the carbon cycle in the 21st Century and an assessment of carbon-climate-human interactions as presented in Grubber et al. (2004).
Carolyn Snider brought
six different kinds of dark chocolate for the Tasting: After Eights (1), Lint Lender Truffles (3), Purina 60% (2), Toblerone dark, Ghiradelli dark chocolate squares, and Lindt bittersweet chocolate bar, 80%.  The votes are in parentheses.
Oct. 4: Chris Field participated in the 52nd meeting of the Executive Committee of SCOPE (Scientific Committee on Problems of the Environment) in Rome.
Oct. 11: Adam Wolf led the FLAB discussion about carbon release from permafrost. Chris brought several brands of scones (including one homemade) for the Tasting. We compared those with different fat content which were crumbly, sweet or fruity. All were tasty.
Oct. 18: Ben Houlton led the continuing discussion about carbon sequestration in tundra and oceans. The availability of phosphorus may be important. Noel Gurwick brought 10 packages of cheddar cheese from different companies to compare in Taste. They were all listed as sharp but varied in age from 6 yrs to 4 to 2 to unknown. We agreed that the oldest did not necessarily have the best taste.
Oct. 25: Kathleen Treseder, our Seminar speaker, spoke to us about a variety of subjects including her research and career. There was also more discussion about various papers covering carbon uptake.
Tasting: John Juarez brought six brands of applesauce for us to compare. All were organic, but varied in taste between sweet and sour.

Chris Field has received a grant from the Global Climate and Energy Project (GCEP) to study Biomass-based fuels as net carbon-neutral energy sources and to evaluate their potential to help reduce greenhouse gases on a global scale.

Dr. Kathleen Treseder from Ecology & Evolutionary Biology and Earth System Sciences, Univ. Calif., Irvine spoke about Fungi, Ecosystems, and Global Change. She had earned her doctorate at Stanford with Peter Vitousek and is now an Assistant Professor. For us, she described recent work tracing soil nitrogen and carbon through mycorhizal filaments stretching
several feet through the soil to a plant's roots. Thanks to new fluorescent labels, this path was clearly visible in her photos.
Caldiera Lab

Damon Matthews has joined the Ken Caldeira for the fall of this year as a post-doctoral (but almost sabbatical) researcher. Damon got his PhD at the University of Victoria and did his first post-doc at University of Calgary. He has a faculty appointment at Concordia University in Montreal, but decided to delay his start there by four months so that he could first gain experience at the DGE.  Damon and Ken will be studying how various factors affect the climate/carbon feedback.

Asner Lab
Masahiro Negishi is a new technician in Asner's group.
Maoyi Huang welcomed a new daughter named Kaixin Catherine Hou on Sept. 19.
Oct. 2: Chris Field and Ken Caldeira spoke at the 2006 Transatlantic Science Conference in Washington held at P Street. The meeting was Jointly sponsored by the Norwegian Embassy in the US and by Carnegie. Ken's talk was on the possibility of geoengineering the climate of the Arctic.
Oct. 26: Caldeira spoke in London to a group developing rules on treating sub-seabed carbon storage under the OSPAR and London Conventions. His topic was on possible environmental consequences of CO2 leaks from that stored in geologic formations beneath the sea floor.
Oct. 26: Dave Kroodsma was at the end of a week in Lima, Peru where he predicts even worse traffic and water problems in years to come caused, in part, by global warming.
Oct 31: Dave appears to have traveled south from Lima to Pisco and then over the mountains eastward to Ayacucho.
Global Ecology Fall Picnic, 10-21-06
Over 70 Carnegie members, families and guests attended our annual picnic on a beautiful, warm afternoon. Fresh, barbequed salmon was accompanied by a variety of salads. Members had been invited to bring a dessert, and the response was fantastic (decadent!). A Brazilian Samba Band that Paulo had discovered entertained us. Miko and Dahlia did their best to encourage others to sway to the samba beat. Perhaps most of us were too full of food and beverage to move in the warm sun. Special thanks to Linda, Yuka, & Robin for helping Chris organize this event.
