Activity Description

2002  

  • TG-05 supports two student stipends under the direction of Prof. Carlos Alberto Schenato at the Lutheran University of Brazil (ULBRA) in Santarém and Raimundo Cosme (EMBRAPA - Amazônia Oriental) for development of surface hydrologic and biogeochemical transport studies in watersheds of Rio Moju, Curua-Una, Rio Tatui, and Rio Curua do Sul.

  • Artaxo's two students, Aline Sarmento Procópio and Luciana Varanda Rizzo have been involved in all aspects of the project in Brazil, including setting up the equipment in the aircraft, debugging equipment problems, communication with the airplane pilots, and logistics. Mike Hahn (NOAA/CMDL) visited them in Brazil for training.

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?
        CD-Q3a - How do pools and fluxes of carbon and nutrients (in soils) of pasture/cropland change over time and what factors determine carbon gain or loss?
        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?

Land Cover and Land Use Change:

        LC-Q1 - What are the rates and mechanisms of forest conversion to agricultural land uses, and what is the relative importance of these land uses?

Nutrient Dynamics and Surface Water Chemistry:

        ND-Q1 - How do stocks, cycling rates and budgets of carbon and important elements nitrogen, phosphorus, potassium, calcium, magnesium, and aluminum change under different land covers and land uses?
        ND-Q2 - Are nutrients major factors that control the rates of regrowth and carbon accumulation in abandoned pastures and regrowing secondary forests?
        ND-Q4 - How do changes in land use and climate alter the stocks, processes and fluxes of dissolved and particulate organic matter, nutrients, and trace gases from the uplands across the riparian zones and floodplains and down the channels of river corridors?
        ND-Q4a - How will the composition and quantity of nutrients and organic matter entering and being processed within streams be altered under different land-use change scenarios?
        ND-Q4b - Are there unique signatures that can be traced downstream?
        ND-Q5 - What is the importance of periodically "wet" environments (from moist soils to standing and flowing waters) for the land and atmospheric balances of nutrients, carbon dioxide, trace gases, and water and energy on multiple scales?

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-Q2 - What is the (climatically driven) seasonal and inter-annual variability of trace gas and aerosol fluxes between the atmosphere and different land use and land cover types?
        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?
