BACKGROUND AND OBJECTIVES OF LEG 181
In summary, our knowledge of Southwest Pacific ocean history, and in particular the development of the ACC-DWBC system, is extremely poor. Leg 181 therefore drilled seven holes in the eastern New Zealand region in order to attempt to reconstruct the stratigraphy, paleohydrography, and dynamics of the DWBC and related water masses. The sites composed a transect of water depths from 393 to 4460 m and spanned a latitudinal range from 39°S to 51°S. Leg 181 drilling has provided the data that are needed to study a range of problems in Southern Ocean Neogene paleohydrography, sedimentology, paleoclimatology, and micropaleontology.
