Sediment Loads of the Amazon River, Brazil

Brazil – June 4th, 2013

Sediment loads can be calculated by converting cosmogenic nuclide-derived rates using their sediment-producing areas. The fluctuations in the modern sediment loads of the Amazon River are due to the absence of long-term deposition within the basin and to the buffering capability of the large Amazon floodplain. The buffering capability dampens short-term, high-amplitude fluctuations (climatic variability in source areas and anthropogenic soil erosion) by the time the denudation rate signal of the hinterland is transmitted to the outlet of the basin (click here for more information).
