Training and Education Activities - Proposed:

We will continue to collaborate with Brazilian institutions and to support training of students with ties to Amazonian institutions. The current Brazilian researchsers (Alex V. Krusche and Maria Victoria Ballester) have recently been appointed to full time research appointments and will participate in this proposal as full co-PIs. Three students under their direction will complete their Ph.D.s on aspects of the proposed work. Sergio Candido de Gouveita Neto, a Ph.D. student at CENA, is focusing on dissolved organic and inorganic fluxes in the microbasins. He finished his field collections in April 2005. Nei Kavaguichi Leite is completing his Ph.D. thesis on the importance of water movement and carbon and nutrient transformations in riparian zones at different scales. Both of these students are from the Amazon (Rondônia) and worked on our LBA project as undergraduates (from UNIR and ULBRA). They plan to return to Rondônia after they finish their Ph.D.s. A new student will work on the regional extent of riparian zone transformations using remote sensing. The graduate students will study English to facilitate their communication with colleagues outside of Brazil, will attend an international scientific conference and spend time in residence at MBL. They will participate in writing papers, building the models, and in the Synthesis Workshops on catchment hydrology and biogeochemistry.

Science Questions:

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-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-Q4c - To what extent do intact riparian zones buffer streams against changes due to anthropogenic activities in surrounding uplands?
