Seminars
In November, Greg Asner and Dave Knapp traveled to Sao Paulo, Brazil to attend the 18th "Large-scale Biosphere-Atmosphere Experiment in Amazonia" (LBA) Science Meeting.  They presented the results of a recent paper, published in Science, on selective logging in the Amazon to an international group including Brazilian officials.

On November 15, Ken Caldeira kicked off a meeting of the Society of Petroleum Engineers on carbon capture and storage in Galveston, Texas, with a general talk on the science of human-induced changes to climate and ocean chemistry, and
In Washington, DC, on November 21, Ken participated in a planning meeting for federally funded R&D in the area of carbon capture and storage as part of the Bush Administration's effort to develop a Climate Change Technology Program.

You're sure to enjoy Dave Kroodsma's Web Blog at <www.rideforclimate.com>. He made a flying side trip to Florida, and was responsible for about 1 metric ton of carbon dioxide released to the atmosphere. For this he paid $12 to www.climatecare.org to offset these emissions through their various projects. Soon he'll be on his way to Mexico by bike.

Nov. 30, Pete Raymond, Yale School of Forestry & Environmental Studies spoke on The Lateral Transport of Atmospheric CO2 to Rivers. His research focuses on the carbon cycle in large rivers and the coastal zone, utilizing the natural isotopes of carbon (C13
and C14) to determine major sources, sinks, and ages of various carbon pools in the natural environment.  Current research includes determining how carbon pools are transformed in estuaries, the physics of air-sea CO2 exchange, and determining the age and composition of carbon being transported from land to the ocean.
Nov. 16, Dr. Ove Hoegh-Guldberg, Centre for Marine Studies, Univ. Queensland, Australia speaking on Coral Reefs in 2050: Life in a warm acidic ocean. Recent UNEP estimates have put the loss of reefs by the year 2100 at 30-50% of currently healthy coral reefs. Ove's laboratory has become a
focal point for studies trying to understand the basis of stress in reef-building corals. Not only would this stress be disastrous for the plants and animals living on these reefs, but the huge economic loss to Australia would be significant if the Great Barrier Reef were no longer the great tourist attraction that it is today.
Jasper Ridge Global Change Experiment
Nov. 14 & 15, the Jasper Ridge Global Change Experiment held its annual "data fest" at the Department of Global Ecology. Participants from Northern Arizona Univ., the Univ. Massachusetts, the Univ. Wisconsin, Michigan State, UC Berkeley, the Lawrence Berkeley Lab, the National Center for Ecological Analysis and Synthesis, and the Universite Paris-Sud joined scientists from Carnegie's Dept. Global Ecology and Dept. Biological Sciences at Stanford to give brief summaries of their findings from the past year and to discuss future directions.
Reported studies spanned a wide range of topics including microbial ecology, elemental fluxes, plant and soil chemistry, remote sensing, and ecosystem modeling. Discussion about future directions focused in on data synthesis among research groups. The team identified several foci for syntheses and began outlining approaches for moving forward on some of these. A particularly rich discussion surrounded the potential to synthesize data from numerous investigations of microbial and ecosystem processes at the JRGCE.
In conjunction with this meeting, Audrey Niboyet returned for the week from Paris. She now has her Master's Degree based, in part, on analyses of Jasper Ridge plants and is embarking on her PhD studies at the Univ. Paris.
Nov. 9, Dr. Jim Zachos, Dept. of Earth Sciences, UC Santa Cruz, speaking on A Rapid Rise in Greenhouse Gas Concentrations 55 Mya: Lessons for the Future. He is a paleoceanographer who measures the chemical compositions of
fossils to reconstruct past changes in marine temperatures, ocean circulation, continental ice-volume, marine productivity, and carbon cycling. By measuring the C13/C14 ratios in old corals, a mirror image of the rise in CO2 in the atmosphere and oceans over the past two centuries is evident. Jim has documented evidence of a pronounced climatic response to periodic changes in the Earth's orbit.
The talk was followed by a reception in the lobby of the Global Ecology building.
Nov. 2, Dr. Jon Foley,Center for Sustainability and the Global Environment (SAGE), University of Wisconsin, speaking on "Land Use and a Changing Biosphere: Towards a Science of Biospheric Management?"
Field Lab Group
Nov. 2: Chris Field flew in from a discussion workshop in Japan on Climate Change just in time for the 1 PM Lab. Meeting to continue the critic of Chapter 7, Couplings Between Changes in the Climate System and Biogeochemistry.
Nov. 9: Continued discussion/critique of Chapter 7.
Nov. 16: More discussion about the IPCC Chapters, how authors are chosen and the process of putting them together.

Tastings
Nov. 2: Somehow, Chris Field also found time to stop at Robert's in Woodside to pick up six brands of olives for us to taste. We agreed that the two in cans, green & ripe were rather bland, but the Greek and Sicilian were very tasty (salty & spicy). The samples from Morocco and France were also "interesting."

Nov. 9: Alison Appling provided six different brands of potato chips including Terra, Pita, Wasabi and Veggie (spinach & kale). The Wasabi was the most "interesting" but others were good too. Once I started tasting, the salt craving kicked in!

Nov. 16: Chris Field brought a number of examples of sour dough breads including rolls, muffins & bagels. There was discussion of how bacteria can substitute for yeast in the starter inoculation, giving the bread a more acidic taste. A very fresh loaf from Draeger's Market won the taste test.

Foley's work focuses on the behavior of complex global environmental systems and their interactions with human societies. In particular, his research group uses state-of-the-art computer models and satellite measurements to analyze changes in land use, ecosystems, climate and freshwater resources across local, regional and global scales. The team has contributed to our understanding of large-scale ecosystem processes, global patterns of land use, the behavior of the planet's water and carbon cycles, and the interactions between ecosystems and the atmosphere.
