While the surrounding Argentinian and Uruguayan landscapes take on a greener color as spring begins in the southern hemisphere, the Rio de la Plata pours thick brown sediments into the Atlantic Ocean.

The Rio de la Plata is created by the convergence of two other rivers: the Paraná River (left) and the Uruguay (right), both of which flow southwards from the top of the image. On the southern shores of the innermost part of the Rio de la Plata estuary, the city of Buenos Aires can also be seen.
