The seabed is the floor of the ocean or sea. It is also known as the ocean floor, ocean bottom, sea floor, or simply the bottom. Another synonym for the seabed is the benthic zone, which includes the lowest level of the water column and the sediment surface. The seabed is an important ecological system where many marine animals and plants live, and it is also a source of natural resources. In addition, the seabed is a fascinating place to explore with modern technology, as scientists discover new species and geological features hidden beneath the ocean's surface.
