Direct measurements in the Labrador Current

Direct measurements of the Labrador Current along the eastern edge of the Grand Banks were made for a 77‐day period (April–June) in 1977. The mean current was southward parallel to the isobaths with speeds of 46 cm s−1 and 18 cm s−1 at 110 m and 380 m depth, respectively. In addition to a semidiurnal tidal signal the current variations appear to be of two primary types. A low‐frequency (10‐ to 16‐day period) variation dominates the current records at both depths and is coherent with the local wind stress. A 2‐ to 4‐day period variation is evident in the measurements at 110 m depth.
