sea bed
Beneath the waves
The sea bed is the floor of the ocean—the solid surface beneath the water.
Also spelled seabed or sea-bed.
The term appears in contexts from marine biology to undersea mining: Scientists mapped the sea bed using sonar.
Riverbed and lakebed follow the same pattern for freshwater bodies.
