Isopach and structure maps show frequent lobe shifting. The Mississippi Canyon, formed by retogressive slumping, connects to the youngest fan lobe. The upper fan-lobe is characterized by a large, incised, partially infilled, leveed channel. The middle fan-lobe is aggradational, convex in cross section, with a channel-levee complex on its apex. The lower fan-lobe contains a recently active small channel and several abandoned ones. Depositional patterns can be explained by several processes: "fluvial," debris flows, and turbidity currents.completedOceanographyAtlantic Oceanbottom featuresCenozoicchanges of levelcurrentsDeep Sea Drilling ProjectGulf of Mexicomarine geologyMississippi FanNorth Atlanticocean floorsoceanographyQuaternarysubmarine fansturbiditeturbidity currentsEnglishgeoscientificInformation-91.1500-84.300023.470028.4500Mississippi Fan
