March 1: Greg Asner writes about a paper released by Frontiers in Ecology and the Environment highlighting an “old” study from Hawaii that really got our regional carbon stock and emissions mapping going as we see it today all over the world. While our methods have since greatly expanded and improved since the original Hawaii study, this one stands out as one of the most challenging in terms of variation in ecosystem and vegetation types, terrain, and cloud cover.
March 2: Luis Fernandez writes about an article from this month's Smithsonian Magazine that discusses the increasing environmental problems in the amazonian Madre de Dios region in Peru, and mentions the Carnegie study that we did last year with Victor Gonzalez from the University of Machala (Ecuador) which looked at the impact of the major deforestation driver in the region, gold mining, on river ecosystems of the region. http://www.smithsonianmag.com/people-places/A-Mega-Dam-Dilemma-in-the-Amazon.html
March 15: Ken Caldeira welcomes Sharon Gourdji, who recently defended her Ph.D. (Univ. Michigan, Ann Arbor) as part of his group in January and is now in California for a few weeks working at a desk in DGE. Sharon has done a lot of regional inverse modeling work. As part of a short postdoc, she is exploring the degree to which the current ground-based CO2 monitoring network in North America can be used to constrain fossil fuel emissions.
March 30: Sharon Gourdji presented a Seminar titled: Towards improved estimates of regional-scale CO2 surface flux from atmospheric inverse models. Her group has been collecting data from multiple sources about the concentrations of CO2 to compare different models with the goal of removing temporal & annual uncertainties. She is returning to Michigan in a couple of days.
