Internal solitons in the northern South China Sea from insitu observations

In this paper, we demonstrate the characteristics of strong internal solitons at the southern edge of Dongsha Islands in the northern South China Sea （SCS） during May-June 1998, using in situ time series data from the conductivity temperature depth （CTD）, acoustic Doppler current profiler （ADCP） and thermistor chain. Our measurements indicated that the strongest internal solitons were larger than 90 m in wave amplitude, and propagated approximately westward in traveling direction, with the maximum current speed of about 2 m/s and the period of 10-20 min. The strongest internal solitons occurred noticeably during May 14- 16, 1998, which is consistent with the occurrence period of the diurnal-dominated spring internal tides.
