Estuarine and coastal ecosystems carry out many important functions such as storm protection, erosion and deposition control, habitat creation for species, and biogeochemical processing (Kennedy, 1984; Costanza et al., 1993; Levin et al., 2001; Barbier et al., 2008; 2011; Koch et al., 2009; see Chapter 12.06).

The total fish catch in estuaries contributes billions of dollars a year to the U.S. economy.

Why estuaries is the most productive ecosystem?

Estuaries tend to be very rich in organisms. Rivers, before they are diluted by the enormous body of ocean water, have generally high concentrations of many chemical elements needed by plants and animals to build their tissues. Organic particulates draining from the land tend to be sedimented out in the estuary.
