The Marajó várzea is at the mouth of the Amazon River. It covers coastal areas of the states of Pará and Amapá , with an area of 8,857,759 hectares (21,888,000 acres). [ 1 ] Water levels are affected by freshwater flowing down the river and by tidal flows from the Atlantic Ocean . [ 2 ]
A large outflow of fresh and brackish water from the Amazon mouth - the Amazon river plume - extends through the middle of the Amazonia ecoregion, being pulled north by the NBC. Combined with rainfall this lowers the salinity of the ecoregion's waters, to levels that average 35-36.75 ppm.
The mouth of the Amazon River The Amazon basin is the part of South America drained by the Amazon River and its tributaries . The Amazon drainage basin covers an area of about 7,000,000 km 2 (2,700,000 sq mi), [ 1 ] or about 35.5 percent of the South American continent.
The definition of where exactly the mouth of the Amazon is located, and how wide it is, is a matter of dispute, because of the area's peculiar geography. The Pará and the Amazon are connected by a series of river channels called furos near the town of Breves ; between them lies Marajó , the world's largest combined river/sea island.
The Amazon biome has an area of 6,700,000 square kilometres (2,600,000 sq mi). [2] [a] The biome roughly corresponds to the Amazon basin, but excludes areas of the Andes to the west and cerrado (savannah) to the south, and includes lands to the northeast extending to the Atlantic ocean with similar vegetation to the Amazon basin.

The Amazon River is home to about 20 percent of the world's fresh water supply, placing the Amazon Reef at the mouth of the largest river in the world, where every day one fifth of the world's water flows into the ocean from the Amazon River. [5] Because of this, the Amazon Reef is less biologically diverse compared to other reefs of its kind. [4]
The Amazon rainforest, [a] also called Amazon jungle or Amazonia, is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km 2 (2,700,000 sq mi), [ 2 ] of which 6,000,000 km 2 (2,300,000 sq mi) are covered by the rainforest . [ 3 ]
The main island of the archipelago also has the name of Marajó, having about 42,000 km² of area, considered, due to its size, as the largest coastal island in Brazil, extending from the mouth of the Amazon River, between the Line of the Equator and the parallel 1.55º south latitude and, in the E/W direction between the meridians 47º and ...
