Roanoke Sound

Estuary

LOCATION

Roanoke Sound is an estuary found separating Roanoke Island an Bodie Island in the Outer Banks of North Carolina.

IMPORTANCE OF ESTUARIES

Estuaries are semi enclosed bodies of water formed when fresh water from rivers and coastal streams flows into and mixes with salt water of the ocean. The fresh water is slowed from streaming into the open ocean by either surrounding mainland, peninsulas, barrier islands, or salt marshes. This mixing of fresh and salt water creates a transition zone between land and sea known as an estuary. These are places where fish, birds and animals of all sorts congregate to feed, find refuge, grow to adulthood, and stage migrations.
