Secondly, why is Mississippi Gulf Coast Water Brown? 4.5 > The Mississippi River carries vast amounts of sediments (yellow-brown) and nutrients into the Gulf of Mexico, which are then transported westward along the coast by the wind. The nutrients cause a strong growth of algae (green). Oxygen is consumed in the deep water as bacteria break down the algae.

One may also ask, does the Mississippi River run into the Gulf of Mexico?

Where Gulf of Mexico meets Atlantic Ocean?

It is connected to part of the Atlantic Ocean through the Florida Straits between the U.S. and Cuba, and with the Caribbean Sea (with which it forms the American Mediterranean Sea) via the Yucatán Channel between Mexico and Cuba.

In some estuaries, the mixing of fresh water from rivers and saltwater from the sea is extensive; in others it is not. Because fresh water flowing into the estuary is less salty and less dense than water from the ocean, it often floats on top of the heavier seawater.
