Marajó Bay

[4][5][6] Marajó Bay is an estuary consisting of both salt and fresh water, resulting in the classification of an estuarine system.

A circulation process of salinity, temperature, and tidal range in the two different water types occurs in the bay as they meet.

[8] There are many different marine species found in the Bay's waters, some examples of which are Scomberomorus brasiliensis, Cynoscion acoupa, Mugil sp.

[9] Due mainly to its size and geographic location, Marajó Bay has long been used by humans for a variety of reasons.

Additionally, it is frequented by boats as a popular spot for shipping, due to its entrance at the Atlantic, and eventual deeper penetration into the mainland.
