Figure F1. Location of ODP Leg 186 Sites 1150 and 1151. Major current systems and the generalized distribution of sea-surface water masses in seas adjacent to the Japanese Islands are adopted from Takemoto and Oda (1997). C = areas dominated by cold-water masses during the meandering of the Kuroshio Current; W = areas dominated by warm-water masses within the so-called Perturbed Area between the Kuroshio and Oyashio Currents.
