On the Cover: Aerial view of pororoca, or Amazonian tidal bore, as it moves along the coast just north of the river mouth. Tidal currents are responsible for much erosion and transport of sediment on the Amazon shelf, but especially along the coast near the river mouth. The name pororoca is derived from the native word for "'big noise." (Photo by Gilberto T. M. Dias)
