Abstract
Abstract A 349-day series of consecutive hourly readings from a single current meter mooring in the deep water of the Weddell Sea was analysed to determine the tidal currents. Amplitudes and Greenwich phase-lags were found for both the east-going and north-going components of velocity for the eight principal harmonic constituents. Constituents tidal ellipses were drawn for the four most energetic constituents O 1 , K 1 , M 2 , and S 2 ; the current vectors rotated clockwise in each case. Analysis of each successive quarter of the time series yielded results consistent with those from analysis of the entire record. The amounts of barotropic and baroclinic energy in the diurnal and semidiurnal tidal bands are consistent with the barotropic nature of circulation in the Weddell Sea.
