Abstract
    Study of Foraminifera from fifteen cores shows presence of cold-water faunas interpreted as representing glacial stages and/or substages, and of warm-water faunas interpreted as post-glacial and interglacial stages and/or substages. These sequences are similar to those previously reported from the northwestern Gulf of Mexico. The amount of post-glacial deposition is greater on the lower continental shelf and upper continental slope than on the lower slope and basin. Variations in amount of post-glacial sedimentation within these topographic provinces are demonstrated. Two cores located in the bottom of Mississippi Canyon contain faunas and sediments which have been displaced downslope, presumably by turbidity currents. It is suggested that the turbidity current was confined to Mississippi Canyon, and that submarine canyons generally tend to localize many turbidity currents.
