Lecture 11: Estuaries


Estuaries provide an essential habitat for wildlife but they are susceptible to pollution from rivers and urban runoff. The chemical processes at estuaries determine the fluxes of riverine species into the ocean. At estuaries, river water (pH 4-7, salinity < 5 ppt) mixes with seawater (pH 8.3, salinity 35 ppt) causing metals to sorb to FeOOH and colloidal FeOOH/organic complexes to flocculate and be incorporated into sediments.
