Internal oscillations of tidal character in certain B.C. inlets Davis, Patrick Austin

Abstract

A study of series of profiles of temperature and current at one station in Knight Inlet, and of temperature at two simultaneous stations in Bute, have been made in conjunction with seasonal profiles of temperature, salinity, and the associated density. On this basis certain hypothetical models have been fitted to the dynamics within the inlets. A calculation of the possible modes of progressive internal waves for the two inlets has led to< agreement only in Bute Inlet. A qualitative explanation of the condition in Knight in terms of the dynamic circulation over the sill has led to suggestions as to the mechanism, of exchange in the deeper waters of the inlet, and speculation as to the possibility of prediction of states within an inlet in terms of its topography, runoff cycle, and communication with the coastal waters.
