摘要
The preliminary study on nanodiatom in the Taiwan Strait was carried out using transmission electron microscopy (TEM) in February 1995. Thirty-three species of nanodiatom (< 20 μm) were identified, among which, 6 were new recorders in China. The dominant species were Minidiscus comicus Takano and Thalassiosira tenera Proschdinae -- Lavrenko in the northern Taiwan Strait (NTS), Minidiscus trioculatus (F. J. R. ) Hasle and Natvicula climacospheniae both in the southern Taiwan Strait (STS). Abundance of nanodiatom was much more than that of microdiatom (>20 μm), and the abundance of nanodiatom in NTS is higher than that in STS. The highest abundance of nanodiatom was at the depth of 10 m of N33o in NTS, while at the depth of 20 m of S105 in STS. The vertical distribution of nano- and micro-diatom of NCI showed that the peak was at the depth of 30 m.
