A shallow coastal water body that is separated from the open sea by a barrier is called what?

Explanation:
Lagoons form behind barriers such as sandbars or barrier islands, creating a shallow, sheltered coastal water body that is separated from the open sea by that barrier. The barrier reduces wave energy and exchange with the sea, giving a calmer, often brackish environment. An inlet is simply a narrow channel that connects a lagoon or bay to the ocean, not the water body itself behind the barrier. A moraine is a glacial deposit, and a longshore bar is an offshore sandbar built by longshore drift—both are different features. So the described feature is a lagoon.
