Bottom Character

Bottom character describes sediment or substrate type of the ocean floor. Whether the bottom character is rocky, sandy, or muddy it affects marine ecology. Different species depend on different habitats, and species adapt to the bottom character they inhabit. For example, eel grass (Zostera marina) is found on sandy substrates, whereas barnacles and kelp attach to a hard substrates such as rocks.

AOOS is affiliated with the Integrated Ocean Observing System and the
