The site is located approximately at 28S 43W,
east of the core of the Brazil Current.
Historical hydrographic data reveals that the sea
surface temperature at this location varies
between 19 and 26C, and the mixed layer depth
increases from 20 m in January to 150 m in
August. Though the region is recognized as
important for the regional continental climate,
there is no knowledge on the interannual
variability and on how these changes are related
to the ocean circulation. Budget for three year
