Pamlico and Albermarle Sounds, North Carolina, USA36.0N 75.9W
Pamlico Sound, in North Carolina, is the largest lagoon along the U.S. East Coast. Here its waters contain sediments and algae and are thus greenish in color. The sound is separated from the Atlantic Ocean by the Outer Banks, a row of low, sandy barrier islands.
Another body of water can be seen just north of Pamlico Sound: Albemarle Sound, a large estuary also on the coast of North Carolina, also separated from the Atlantic Ocean by the Outer Banks. Darker in color than its southern neighbor, it is located at the confluence of a group of rivers, including the Chowan and Roanoke.
