Kjerfve et al. This gives a maximum spring-tidal prism of about 3. The lack of near-bottom current estimates at stations 11 and 12 during winter prevented any comparison with the summertime observations. An evaluation of the flushing time is also provided and shows that during summer, a fold increase can be observed compared to winter 38 days. M 2 amplitude grows from 0. Due to the orientation of the residual current vectors inside the bay, one would feel tempted to suggest that an anticlockwise circulation is normally established inside the BTS where water moves northward towards station 15 and returns via Canal de Itaparica. Near-bottom currents in the summer period were weaker than those near the surface at stations 10 to 12, indicating a significant velocity shear in the water column those near-surface currents were above 15 cm s -1 and more than three times larger than the near-bottom currents. During summer, the upwelling favorable easterlies drive a southwestward flow, while during winter the more frequent occurrence of cold fronts southerly winds tend to reverse the circulation.

    S 0 and represent salinity at the oceanic and innermost stations, respectively. For both periods, data was obtained by: i moored oceanographic stations distributed over the BTS and associated coastal region sampling water temperature, salinity, pressure and velocity fields continuously in 17 stations; ii meteorological stations measuring wind speed and direction in 4 locations in and outside the bay; iii hydrographic surveys sampling water properties over one complete tidal cycle 13 hoursduring spring and neap tides, in 12 stations distributed in and outside the bay.

    Cancel Unsubscribe. South bound residual currents were recorded by all current meters at stations 7 and 17, inside the Canal de Itaparica, with velocities up to 6 cm s -1 at station The lack of near-bottom current estimates at stations 11 and 12 during winter prevented any comparison with the summertime observations.

    His research interests cover marine sedimentology, coastal and estuarine circulation and coastal barrier-estuarine geological evolution. The bay-mouth sand is of marine origin, while that inside Itaparica channel and along the western bay margin is originated from the erosion of sandstone deposits.

    It is anticipated that such set up reduced tidal ranges by cutting both high and low water levels. Inside the BTS, the circulation was mostly tide driven throughout the year, but water properties did change noticeably between summer and winter.

    The second, and strongest, velocity peak was ascribed to the inundation of relatively high intertidal areas along Canal de Itaparica. For BTS, the summer months are part of the dry season, while the winter months are part of the wet season. Morphodynamic controls on tides and tidal currents in two macrotidal shallow estuaries, NE Australia.

    Although the circulation driving forces have been described here, several questions remain and need to be elucidated before a satisfactory understanding of the different spatial and temporal scales involved in the physical oceanography of the bay can be achieved.

    At station 14, the mid-depth current also agreed with this summertime southwestward circulation showing a magnitude of 7 cm s Moreover, larger horizontal and vertical variations occurred during summer for temperature and during winter for salinity. The muddy sediments in the northern half of the bay would be related to a transgressive bay sand-mud facies and to a regressive bay-mud facies.
