The AMANDES project
The name AMANDES is the contraction of AMAzon
ANDEanS. This project, led by
Catherine
Jaendel, is focused on the Amazon estuarine and shelf, and its impact on
the water masses of the neighbor Atlantic.

The general objectives and expected results of
AMANDES are:
- to constrain the nature, transformation and dispersion into the ocean of
the fluxes of trace elements and isotopes weathered from the Andes Mountains
and transported by the Amazon river and estuarine down to seawater;
- to improve the coupled dynamical modeling of the shelf/slope/open ocean
system of the Amazon mouth, for a better quantification of:
- the transport of freshwater and its impact on the regional
oceanic circulation;
- the tidal effect on this transport and the sediment
re-suspension/redistribution;
- the impact of all these dynamics on the transformation and
dispersion of the chemical elements;
- to quantify the impact of these integrated fluxes on the chemical
composition of the water masses flowing along the Amazon margin, constrained
simultaneously by the tidal forcing, the North Brasil current and the wind
stress.
Three complementary disciplines (continental and
marine geochemistry, physical oceanography, and modeling including satellite
data assimilation) are associated to reach these objectives.
