One of the long-standing goals of the Deep Sea Drilling Project (DSDP) has been to study the oceanic paleoenvironment of the western Pacific through deep sea drilling. Leg 86 was planned in the western North Pacific in order to address this problem. The primary objective of Leg 86 was to drill a northsouth transect of four sites across the Kuroshio Current system, from subtropical to subarctic waters. Secondary objectives of Leg 86 included the following: First, to hydraulic piston core the Cretaceous/Tertiary boundary at the Shatsky Rise for midlatitude calcareous biostratigraphic, paleomagnetic, and geochemical studies and Second, to recover a "type" North Pacific red clay section for geochemical, paleomagnetic, and geotechnical studies.
