1. Yang, Cai-Ming. Observations of Kuroshio flows near Lanyu by using Lowered ADCP.

Degree: Master, Marine Biotechnology and Resources, 2008, NSYSU

In the last decade the lowered Acoustic Doppler Current Profiler (LADCP) has become an important instrument in measuring full-water-depth profile of velocity in the open ocean. The basic principle of the LADCP is to lower one or two self-contained ADCP, one looking downward and the other looking upward, together with the CTD rosette during the hydrographic cast. After careful analysis of the ADCP data it is possible to retrieve surface âto-bottom profile of horizontal current velocity. In the present study we have conducted three cruises (21-25 April, 7-10 July and 11-13 October of 2007) in the Lanyu area to survey the Kuroshio flow structure by using the first set of LADCP in Taiwan. A total of 34 LADCP/CTD casts were completed. The results indicate that a major branch of the Kuroshio is located at the region between Taiwan and Lanyu, with a seasonal variation of flow intensity and vertical extent. Surface currents can reach a maximum speed of 70-140 cm/s northward. Kuroshio has a strongest speed (~140 cm/s) in October followed by July (~100 cm/s) and April (~90 cm/s). The vertical extent of the Kuroshio can extend to 400-m depth in October, 600-m depth in July and 400-m depth in April. A southward reverse current can be observed off the southeast Taiwan coast in depths between 200 and 800 m and the speed ranges between 30 and 60 cm/s. This southward flow is strongest in April (~60 cm/s), followed by July (~40 cm/s) and October (~30 cm/s). A cyclonic, cold eddy was observed in the eastern side of Lanyu from the shipboard ADCP data during the April cruise. The Kuroshio flows to the northwest during ebbs and to the northeast during floods from the LADCP observations at different tidal phases in July. Finally, analysis of the temperature-salinity characteristics of the CTD data reveals that the South China Sea waters can penetrate into and mix with the Kuroshio waters more significantly in summertime than in other season.

2. Kuo, Hui-ming. Analysis of temporal and spatial variations of Taiwan Strait water.

Degree: Master, Physical Oceanography, 2004, NSYSU

The water masses in the Taiwan Strait (TS) contain the Kuroshio Branch Water (KBW), the South China Sea Surface Water (SCSSW), and the China Coastal Water (CCW). The seasonality of their temporal and spatial variations is modified by the East Asia monsoon and the bottom topography. Hydrographic data acquired during 1985-2003 were studied using a cluster analysis for the classification of the water masses. In addition to the three water masses identified previously, the cluster analysis further classified the Subsurface Water (SBW) under 100 m depth in the Penghu Channel (PHC) and the Coastal Water (CW) along the China coast in summer. Results derived from the cluster analysis together with the T-S diagram suggest that the KBW and SBW dominates in the PHC, whereas CCW occupies in the north TS from January to April. After May, the SCSSW replaces the KBW in the TS through PHC. Meanwhile, the CW distributes along the northwest bank of the TS. After the onset of northeast monsoon in October, the CCW intrudes southward to the northern TS, yet the KBW is confined in the PHC. A zonal oceanic front is clearly seen between the two water masses over the Chang-Yuen Rise in winter. As for the NTMW, it presents below 30 m depth during May and September, and would distribute in depths 0-100 m in other months. The monthly hydrographic databank established in this study has a horizontal grid resolution of 10'x10'. The vertical levels are set at depths 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 125, 150, and 200 m. The study also concludes that there is hardly a northward flow in the TS in winter connecting the South China Sea Warm Current to the so-called Taiwan Warm Current.

3. Chen, Chung-Kuang. Seasonal Variation of Fluxes and Water Masses in the Penghu Channel.

Degree: Master, Physical Oceanography, 2004, NSYSU

This study use the hydrography and current data measured along a zonal transect across the Penghu Channel (PHC) during 1985-2003 to calculate through-flow, temperature and salt transports (Q, TT and ST), and analyze hydrographic transects and water masses variations through the PHC. The influence of the El Niño on the variations of temperature and salinity in the PHC is also investigated. The calculated Q is about 0 Sv (1 Sv = 106 m3/s) in winter, and the TT, ST, heat flux are amount to -0.005Ã1015 W, -2Ã106 kg/s, -1.6Ã106 W/m2; during winter-spring period, the Q increases from 0.5 to 1 Sv as the northeast monsoon weakens, and the TT, ST, heat flux are amount to 0.052~0.113Ã1015 W, 20~40Ã106 kg/s, 16~35Ã106 W/m2, respectively. The Q peaks to 1.5 Sv at the end of southwest monsoon in summer, and the TT, ST, heat flux are 0.162Ã1015 W, 52Ã106 kg/s, 53Ã106 W/m2, respectively. The Q decreases rapidly from 1.5 to 0 Sv when the northeast monsoon intensifies in autumn, and the TT, ST, heat flux are 0.162~-0.005Ã1015 W, 52~ -2Ã106 kg/s and 53~ -1.6Ã106 W/m2, respectively. The relationship between the through-flow transport and the wind stress is expressed as Q (Sv) = 1.37+5.58Ãwind stresses (N/m2). The correlation coefficient is 0.97. The water column is strongly stratified in summer and nearly well-mixed in the upper 100 m in winter. The major water masses are the colder and saline Kuroshio Branch Water and the warmer and less saline South China Sea Surface Water respectively in winter and summer. The correlation coefficients for the El Nino index, the Southern Oscillation Index, to the anomalies of depth averaged (< 50 m) temperature and salinity are 0.527 and -0.429, respectively, suggesting that temperature and salinity might be anomalous decrease and increase during the El Niño.
