High Concentration of Sediments in Rio de la Plata
The Rio de la Plata (on the border of Argentina and Uruguay), which frequently seems brown in color due to sediments, is filled with a particularly bright, dense concentration of them in this recent image.
The sediments appear most concentrated where the river first begins to widen, then their color gradually becomes less opaque as one moves east towards the Atlantic. An algal bloom frames the sediments closest to the ocean.
The Lagoa dos Patos and Lagoa Mirim are visible to the northeast, in Brazil. Both also appear brown from sediments.
