Kuroshio Extension Regional Experiment Hydrographic Data: Summer 1992

The primary focus of the Kuroshio Extension Regional Experiment oceanographic field program is the observation of the hypothetical Pacific Deep Western Boundary Current (DWBC), analogous to the DWBC found in the Atlantic. The model of Stommel, H.M. and A.B. Arons (1990). On the Abyssal Circulation of the World Ocean. I. Stationary Flow Patterns on a Sphere. Deep-Sea Res. 6, 140- 154, suggests that a Pacific DWBC should exist but that near Japan it could be northward or southward, depending on model parameters. Observations in this region are relatively sparse. This objective is being addressed with five current meter moorings deployed across the Japan Trench east of Honshu and by a hydrographic section conducted during the deployment cruise in July 1992. This report provides a description of the hydrographic and chemistry data.
