Pamlico and Albemarle Sounds by Coast of North Carolina, USA – January 8th, 201235.3N 75.8W
Visible by the coast of North Carolina, USA, are the Pamlico and Albemarle Sounds. The waters of the former appear greyish green in color, while those of the latter appear brownish. The two are linked by the passages of the Roanoke Sound and Croatan Sound.
Pamlico Sound is the largest lagoon along the U.S. East Coast, being 129 km long and 24 to 48 km (15 to 30 miles) wide. It is a body of water separated from the Atlantic Ocean by the Outer Banks, a row of low, sandy barrier islands. The sound and its ocean inlets are noted for wide expanses of shallow water and occasional shoaling, making the area hazardous for larger vessels.
Albemarle Sound is a large estuary located at the confluence of a group of rivers, including the Chowan and Roanoke. It is also separated from the Atlantic Ocean by the Outer Banks. Much of the water in the Albemarle Sound is brackish or fresh, as opposed to the saltwater of the ocean, as a result of river water pouring into the sound.
