在本文中，我们利用电导率温度深度（CTD）、声学多普勒电流剖面仪（ADCP）和热敏电阻链的原位时间序列数据，展示了1998年5月至6月南海北部东沙群岛南缘的强内部孤子特征。测量结果表明，最强的内孤子波幅大于90 m，行进方向近似向西传播，最大水流速度约为2 m/s，周期为10~20 min。最强的内孤子明显出现在1998年5月14日至16日期间，这与昼夜主导的春季内潮的发生时期一致。
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.
