Abstract—The peculiarities of the internal tidal wave generation in Mamala Bay (Oahu Island, Hawaii) have
been studied based on an analysis of the measurements of the current and temperature profiles and the CTD
data in this region. ITs of local origin, which differ from waves of distant origin (predominant in the bay) by
the presence of high-order modes, have been detected by using special methods for processing current velocities
obtained with the help of ADP acoustic meters. The data of the profilers have been analyzed by using empirical
orthogonal functions. It has been established that waves of local origin radiating from the shelf edge into the
ocean are also present in the total IT field.
