Inhaltsangabe:
- <p>This Initial Reports volume covers Leg 120 of the cruises of the Drilling Vessel <em>JOIDES Resolution</em>, Fremantle, Australia, to Fremantle, Australia, Sites 747–751, 20 February to 30 April 1988.</p> <p>Legs 119 and 120 completed a latitudinal transect in the Southern Ocean between Kerguelen Island (49° S) and Prydz Bay, East Antarctica (67° S), a region critical to the understanding Cenozoic climate and oceanographic development. The Kerguelen Plateau lies south of the present-day Polar Front (Antarctic Convergence) and beneath the main flow of the Antarctic Circumpolar Current. These two oceanographic features have a major effect on global climate and surface-water circulation. During Leg 119, five sites were drilled in Prydz Bay (Site 739 to Site 743) and six sites were drilled on the Kerguelen Plateau (Sites 736 and 737 on the Northern Kerguelen Plateau and Sites 738, 744, 745, and 746 on the Southern Kerguelen Plateau) with the objective of studying the paleoceanographic history of the southern Indian Ocean, the geological development of the Kerguelen Plateau, and the development of glaciation in East Antarctica. During Leg 120, five sites were drilled on the central part of the plateau (Site 747 to Site 751) to test the conflicting hypotheses about the origin of the Kerguelen Plateau and to determine when and how the plateau formed.</p>
