Pamlico and Albemarle Sounds, North Carolina, USA35.3N 75.8W
Two large sounds can be seen by the Atlantic Coast of the state of North Carolina: Pamlico Sound (greenish, below) and Albemarle Sound (darker green and brown, above). Both sounds are separated from the Atlantic Ocean by the Outer Banks, a row of low, sandy barrier islands.
Pamlico Sound is the largest lagoon along the U.S. East Coast, being 129 km (80 mi) long and 24 to 48 km (15 to 30 miles) wide. The Neuse and Pamlico rivers (the latter is the estuary of the Tar River) flow in from the west. Pamlico Sound is linked on the north with Albemarle Sound through Roanoke Sound and Croatan Sound (passages). 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.
