coastal ecosystem
Definition

Marine environments bounded by the coastal land margin (seashore) and the continental shelf 100-200 m below sea level. Ecologically, the coastal and nearshore zones grade from shallow water depths, influenced by the adjacent landmass and input from coastal rivers and estuaries, to the continental shelf break, where oceanic processes predominate. Among the unique marine ecosystems associated with coastal and nearshore waterbodies are seaweed-dominated communities, coral reefs and upwellings.
