| Abstract | Suspended matter in Astoria canyon was monitored by means of an in situ nephelometer and by means of light-scattering and particle concentration measurements performed aboard ship on water samples. Nephelometer profiles obtained along the axis of the canyon in February and April 1973 indicate that the canyon is divided into two distinct zones: a nearshore zone in which the suspensoid distribution undergoes large changes and an offshore zone in which the distribution varies to a much less degree. A 15-hour time series of light-scattering and particle concentration profiles at a depth of 1100 m in the canyon shows extensive and rapid changes in suspended matter concentration at several depths. The effect of nonsteady state distributions of suspended matter on calculations of the coefficient of eddy diffusivity is examined and shown to be an important consideration in a submarine canyon. |
