Training and Education Activities - Proposed:

As a contribution to training and education we intend to provide continued support to help Claudio Barbosa, Thiago Silva, Lauren Belger and Alexandre Kemenes complete the analysis of their data and preparation of their Ph.D. theses and subsequent publications. Our proposed budget commits about 35% to support training and education. Evlyn Novo and Bruce Forsberg are actively involved in postgraduate teaching programs at INPE and INPA. Melack has joined the students at their field sites and met regularly with them in Brazil as part of their mentoring.
As a contribution to capacity building in Amazonia we have set-up a fully equipped gas chromatograph available for use in Forsberg’s laboratory at INPA. In addition, we have set-up a digital videography analysis station at INPE with technical support for its use by those in need of high-resolution optical data.


Training and Education Activities - Accomplished:

Currently none available.

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?

Nutrient Dynamics and Surface Water Chemistry:

        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-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?
