Marine geological and geophysical data have been collated and synthesized for the area in the North Pacific bounded by 29/sup 0/N and 31/sup 0/N; 156/sup 0/W and 160/sup 0/W. Particular emphasis has been given to assessing the disposition of the sediment blanket and underlying crystalline basement (layer 2) through the examination of a variety of seismic observations. In July 1975 a 15-day cruise aboard R/V VEMA focused on the collection of a suite of piston cores, heat-flow measurements, high and low frequency seismic profiling, wide angle seismic reflection/refraction using sonobuoys, special near-bottom seismic experiments bathymetric measurements, special heat-transfer experiments, and a variety of complementary marine geological and geophysical observations. The preliminary results of the cruise and their interpretation in the framework of other existing data is summarized.
