Near-surface current measurements from locations along the channel of the St.Lawrence Estuary between Trois Pistoles and Baie Comeau are examined for consistent evidence of internal tides. The harmonic constituents of the local tidal streams at each site were estimated by harmonic analysis of the records, and from these were subtracted estimates of the harmonic constituents of the local barotropic tidal streams (those due to surface tides alone)....
