Cruise LEE8-76-NP began with the departure of the U. S. Geological Survey Research Vessel S. P. Lee from Adak Island, Alaska, at 0204 GMT on 29 September 1976. The intended cruise track was southwest from Adak to Tenchi Seamount at the northern end of the Emperor Seamount chain, southward along the Emperor Seamounts to Koko Seamount, and westward from Koko along the Hawaiian Ridge to the cruise termination port of Honolulu, Oahu. The cruise was scheduled to arrive in Honolulu at 2200 GMT on 21 October. The main purpose of the cruise was to obtain geophysical data and samples of volcanic rock from the volcanoes that form the Emperor Seamounts. These data and samples were needed for an ongoing experiment, which included the proposed DSDP Leg 55 drilling in the Emperor Seamounts, designed to test the hot-spot hypothesis for the origin of the Hawaiian-Emperor volcanic chain (see Jackson et al, this volume). A secondary purpose of the cruise was to conduct site surveys for Leg 55 drilling on Suiko Seamount, a potential reentry target, and on several other major seamounts in the chain that were potential sites for single-bit holes.
