Abstract:

Deep-water measurements were obtained from a closely spaced hydrographic section that crossed the Japan Trench and the Kuroshio in the vicinity of the Kashima 1 Seamount. Vertical sections of temperature, salinity, density, oxygen, and nutrients are discussed for water below 1000 m. Hydrographic properties are perturbed in the vicinity of the seamount. Contrasting variabilities are found in the deep-water characteristics northwest and southeast of the seamount. Geostrophic calculations and properties suggest a mean deep-northward flow greater than 3 cms between 3000 m and 5800 m just east of the seamount. At the northwestern extreme of the section the existence of a southward-flowing Deep Western Boundary Current is suggested by silica distributions, as well as the dynamical properties.
