Training and Education Activities - Proposed:

Training and education has been an integral part of our LBA work. Data collection, sample analysis and site operation have been managed by Brazilian students and technicians. Jorge José Pinheiro Macêdo and Ocidne Franck A. Magalhães, Santarém undergraduate students, assisted with vegetation surveys and layout of experimental plots, trained by Brazilian forester Edna Gomes Tenório Guimarães and Harvard researcher Elizabeth Hammond Pyle. Dulcyana Ferreira, Kleber Portilho and Elder Campos, all students at universities in Santarém, were trained in forest ecology and held bolsas under the supervision of Plinio Camargo. All worked several years and presented posters and talks at LBA meetings. Dulcyana completed her undergraduate thesis, Carbon Fractionation in Forest Leaf Litter, and graduated with a degree in biology. We collaborated with Plinio Camargo’s graduate student (now post-doc) Simone Vieira, and were co-authors with her on several papers. Kadson Olivera Silva currently holds a bolsa working with our group.
Several Harvard undergraduates and graduate students have done fieldwork and research in Brazil. Ann H. Rice spent two months working in the field and completed her honors undergraduate senior thesis, Carbon Balance and Forest Dynamics in an Old-Growth Amazonian Forest, graduating in biology from Harvard. Gregory W. Santoni completed an undergraduate Honors thesis in chemistry and physics at Harvard based on his fieldwork in Brazil, title. Lucy Hutyra, a third year Ph.D. student, has been working with biometric and tower measurements in Brazil for six years. For her thesis Lucy will work on the synthesis of the forest sustainability modeling and analyze the carbon budgets based on ground-based measurements.
We also trained Fernando Alves Leão and Daniel Amaral of Santarém in electronics, and maintenance of our engineered systems, as well as in computer interfacing and control. Based on his work as field technician from 1999 to 2001, Fernando has moved on to pursue advanced education.
BARCA provides a unique opportunity for training and capacity building. Only Brazilian citizens will fly on the aircraft, hence operation of the in-flight instruments will be performed by Brazilian technicians, providing a unique training and job experience opportunity that will provide a pool of talented environmental researchers.
Once the data collections are complete, we will focus on training of, and collaboration with, Brazilian graduate students, post-docs, and scientists in the analysis and synthesis of LBA and BARCA data. We sponsored MA graduate Marcos Longo (from USP/Maria Asusncaõ de Silva Dias), who will matriculate in September 2005 and his thesis work will focus on the meteorological and physical aspects of carbon dynamics in this project. We also sponsored Simone Vieira for a Visiting Scholar fellowship at Harvard’s David Rockefeller Center for Latin American Studies. If this is not awarded, we plan to bring Dr. Vieira here for as long as we can afford, to work on analysis of tree demography and implications for vegetation change. We expect to work closely with students of Paulo Artaxo in analysis of BARCA data.

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-Q2 - How do biological processes such as mortality and recruitment or succession following land use change influence the net annual carbon balance for different land cover and land use types?
        CD-Q3b - How does selective logging change the storage and cycling of carbon in forests?
        CD-Q3c - What factors (biologically mediated, land use history, soil properties, etc.) control the rate of carbon sequestration in biomass and soils of regrowing forest?
        CD-Q3d - What portion of the Amazônia–wide carbon flux is from fire? How do ecosystems recover from fire? What are the relations between land management and fire occurrence/frequency?

Nutrient Dynamics and Surface Water Chemistry:

        ND-Q3 - What are the processes and consequences of atmospheric horizontal transport of nutrients (wind) on the nutrient stocks and cycles of ecosystems within the Amazon basin at various spatial and temporal scales? For example, what are the effects of Saharan dust inputs, losses and re-distribution due to fire, and links between physical climate models and nutrient cycling?

Trace Gas and Aerosol Flux:

        TG-Q1 - How are fluxes of trace gases and aerosols between ecosystems (both upland and wetland) and the atmosphere of Amazônia affected by land cover and land use change?
        TG-Q3 - Are losses and gains of carbon from Amazônian ecosystems in forms other than carbon dioxide (e.g. carbon monoxide, methane, volatile organic carbon, organic aerosol) of sufficient magnitude to influence ecosystem carbon balance?
