seamounts
Submerged volcanic peaks
Seamounts are underwater mountains rising from the ocean floor but not reaching the surface.
Unlike islands, they remain submerged, often by thousands of feet.
Seamounts are typically volcanic in origin and serve as important marine habitats, attracting diverse sea life: The expedition mapped previously unknown seamounts in the Pacific.
