From September 2008 through February 2009, Acoustic Doppler Current Profilers ADCPs measured flow in pairs at the four entrances and exits to the Turkish Strait System. Barotropic tide structures were observed for both diurnal and semidiurnal frequencies in the AegeanDardanelles entrance. At the DardanellesSea of Marmara entrance some baroclinic structure was observed with diurnal tides having higher energy in the upper layer compared to the lower layer. Baroclinic structure in the semi-diurnal tides was observed at the BosphorusSea of Marmara entrance and diurnal oscillations were weak. Both diurnal and semi-diurnal oscillations were weak at the BosphoruBlack sea entrance as the temporal evolution of the flow was more concentrated at low frequencies in the form of a mid-water-column jet.
