The ecology of intertidal sand and mud flats is described in the 

 enclosed report. Although examples of the ecolonical processes 

 were drawn from coastal North Carolina, most of the functions and 

 principles can be widely applied to intertidal shorelines of sounds, 

 lagoons, estuaries and river mouths in temnerate zones throuahout 

 the world.
