Training and Education Activities - Proposed:

One Brazilian and one US graduate student will work directly on aspects of this project at UAlbany SUNY. Mr. Luiz Medeiros, who has just completed his MS degree at the U. Fed. de Santa Maria (UFSM), will begin work on his Ph.D. at UAlbany also in the Fall 2005 semester. He is supported by a CAPES/Fulbright graduate fellowship from the Brazilian government. Mr. Matt Czikowsky is currently a Ph.D. student at UAlbany. He has been involved in the field measurements of LBA-ECO. Analysis of data from this project will form part of his doctoral dissertation.
In Brazil, Mr. Julio Tóta plans to complete his Ph.D. dissertation at the Univ. of São Paulo, at the same time working as a scientist at the LBA Project Office in Manaus. His topic is the subcanopy CO2 advection, observations made using the instruments, software, and experimental design of our group. A number of graduate students at UFSM will continue working on data from LBA-ECO. These include Hans Zimerman and Vagner Anabor.


Training and Education Activities - Accomplished:

Science Questions:

Carbon Dynamics:

        CD-Q1 - What is the (climatically driven) seasonal and interannual variability of the carbon dioxide flux between the atmosphere and different land cover/use types?
        CD-Q3 - What are the relative contributions of fluxes from natural and disturbed ecosystems to the net Amazônia-wide flux?
