On the Gulf of Mexico shelf, elements of the foraminiferal fauna also move in the seaward direction due to the modification of the environment by the Mississippi River.<ref name=ch04r77>Poag, C., W., 1981, Ecologic Atlas of Benthic Foraminifera of the Gulf of Mexico: Woods Hole Marine Science Institute, 174 p.</ref> High rates of deltaic sedimentation with coarser sediment grains, abundant terrigenous organic matter, and modified salinity and temperature greatly affect the local environment. Biofacies distribution responds to these environmental modifications.
