2007年8月夏季中国科学院南海海洋研究所南海北部开放航次期间,在北纬18° - 22°, 东经107° - 122 °范围内使用"实验三号"科考船开展了水体沙壳纤毛虫的研究,探讨了沙壳纤毛虫的空间分布和种类组成.本航次36个站位中共鉴定出24属44种沙壳纤毛虫,其中优势种为长形旋口虫Helicostomella longa 和根突拟铃虫Tintinnopsis radix,沙壳纤毛虫丰度变化范围为 0 - 2 200 cell/L,平均丰度为221 cell/L,从沿岸向外海方向,沙壳虫种类和丰度逐渐减少,其中A1站丰度最高(2 200 cell/L),种类数最多(10).夏季南海北部的上升流和珠江冲淡水携带的营养盐刺激了浮游植物的生长,影响着南海北部沙壳纤毛虫虫的种类组成和空间分布.夏季南海北部沙壳纤毛虫丰度与叶绿素a呈显著正相关,而与温度相关性不明显.夏季南海北部的上升流和珠江冲淡水携带的营养盐刺激了浮游植物的生长,影响着南海北部沙壳纤毛虫的种类组成和空间分布.

Tintinnids, which are loricate planktonic ciliates, were enumerated and identified in samples collected from 36 stations between 18°-22°N, 107°-122 °E in northern South China Sea. 44 species belonging to 24 genera of tintinnids were recorded. The dominant species were Helicostomella longa and Tintinnopsis radix. Tintinnid abundance ranged from 0 to 2200 cell/L, average abundance of tintinnids is 221cell/L in the surface water. Tintinnids abundance and species numbers decrease from coast to offshore. Upwelling and Pearl River discharge influenced the distribution by nutrients supply. Maximum abundance (2200 cell/L) occurred in the surface water of station A1, Maximum of species richness (10 species) was also found in A1. Tintinnids abundance showed a positive correlation with chlorophyll a concentration, and no significant correlation was found between tintinnids abundance and temperature.
