seabeds
Underwater terrain expanses
Seabeds is the plural of seabed—the floor of a sea or ocean.
The seabed may be rocky, sandy, or covered in sediment, and hosts ecosystems from coral reefs to hydrothermal vents.
Scientists mapped the seabeds of the Arctic Ocean.
Drilling for oil on continental seabeds requires specialized equipment.
