Egham, Surrey TW20 0EX, United Kingdom. One of the major aims of Leg 175 was to develop an understanding of 4Quaternary Environmental Change the relationship between wind-driven upwelling intensity and surface Research Group, Department of water productivity. In this paper, such a relationship during the late Geography, University of Durham, Pliocene intensification of the Northern Hemisphere glaciation (INHG) Science Site, South Road, Durham ~2.54 Ma is examined.
