Amazon Mouth. Brazil

September 15, 2006
Visible on this Meris image is the Amazon River flowing into the Atlantic Ocean. The Amazon River is one of the two longest rivers in the world (the longest being the Nile), but is the largest river in the world based on its flow.

The Amazon river releases about a fifth of the total volume of the Earth's freshwater. The amount of freshwater in the oceans can be observed by measuring the ocean's salinity. A change in the amount of freshwater into the oceans, may affect the ocean currents that determine our climate.

The river carries enormous amounts of suspended sediment all along its course; this silt deposit has created numerous islands in the river mouth, out of which Marajo Island is by the largest (its size is comparable to Switzerland's).
