A comparative study of the soil solution chemistry of two Amazonian forest soils (Central Amazonia, Brazil)
soil water chemical composition forest soils
2009/6/8
Analyses of the chemical composition of rapidly percolating soil water were used to study the genesis of a shallow podzol in a Campinarana forest and a clayey ferralsol from a typical rainforest loca...
Soil water storage and groundwater behaviour in a catenary sequence beneath forest in central Amazonia：II. Floodplain water table behaviour and implications for streamflow generation
Soil water storage groundwater central Amazonia streamflow generation
2009/6/8
Valley floor groundwater level data collected during the ABRACOS project (Gash et al. 1996), and published streamflow data from small forested catchments in geomorphologically similar areas nearby hav...
Soil water storage and groundwater behaviour in a catenary sequence beneath forest in central Amazonia：I. Comparisons between plateau, slope and valley floor
Soil water storage groundwater central Amazonia plateau valley floor
2009/6/8
Soil water storage was monitored in three landscape elements in the forest (plateau, slope and valley floor) over a 3 year period to identify differences in sub-surface hydrological response. Under th...
An airborne regional carbon balance for Central Amazonia

2010/1/14
We obtained regional estimates of surface CO2 exchange rates using atmospheric boundary layer budgeting techniques above tropical forest near Manaus, Brazil. Comparisons were made with simultaneous me...
Nitrous oxide fluxes and nitrogen cycling along a pasture chronosequence in Central Amazonia,Brazil
Nitrous oxide fluxes nitrogen cycling pasture chronosequence Central Amazonia
2010/1/12
We studied nitrous oxide (N2O) fluxes and soil nitrogen (N) cycling following forest conversion to pasture in the central Amazon near Santarém, Pará, Brazil. Two undisturbed forest sites and 27 pastur...
