Sea-floor characteristics

Geomorphic features and geographic, compositional, and textural variation in the materials composing the ocean floor. Includes both large-scale structures (such as seamounts and rises) and fine-scale variations in rocks and deposits on the sea floor.
This category is also used for ocean bottom characteristics, sea floor characteristics, and seafloor characteristics.
