Preliminary study on nanodiatom in the Taiwan Strait

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 Minzdzscus comicus Takano and Thalasszoszra tenera Proschkinae-Lavrenko in the northern Taiwan Strait (NTS),Minidzscus trioculatus(F.J.R.)Hasle and Nazricula climacospheniae Booth 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 N₃₃₀ in NTS, while at the depth of 20 m of S₅₀ as in STS.The vertical distribution of nano- and micro-diatom of NCl showed that the peak was at the depth of 30 m.
