The high-latitude South Atlantic Ocean and the adjacent Antarctic Ocean have throughout Mesozoic and Cenozoic time undergone pronounced geographic alterations that have produced a change from a temperate marine climate in the late Mesozoic and Paleogene to a frigid ocean in the Neogene. DSDP Leg 71 was the first of five legs designed to study late Mesozoic and Cenozoic paleoenvironments through the history of sedimentation at the eastern end of the Falkland Plateau, the effect of the plateau as a barrier between water masses during the early opening of the South Atlantic, and the evolution of the Antarctic Convergence.
