| Abstract: |
| Seasonal variation of marine plankton spatial distribution is important in understanding the biological processes in the ocean. In this study, we studied spatial distribution of planktonic ciliate abundance and biomass in the central deep area (station depth greater than 60 m) and the coastal shallow area (station depth less than 60 m) of the southern Yellow Sea (32°–36.5°N, 121°–125°E) in spring (April) and autumn (October–November) of 2006. Our results showed that both ciliate abundance and biomass in the surface waters were higher in spring ((1 490±2 336) ind./L; (4.11±7.81) μg/L) than in autumn ((972±823) ind./L; (1.11±1.18) μg/L, calculated by carbon). Ciliate abundance and biomass in the surface waters of the coastal shallow area were similar in spring and autumn. However, in the central deep area, those values were much higher in spring ((1 878±2 893) ind./L; (5.99±10.10) μg/L) than in autumn ((738±373) ind./L; (0.74±0.76) μg/L). High values of ciliate abundance and biomass occurred in the central deep area in spring and in the coastal shallow area in autumn. Mixotrophic ciliate Laboea strobila was abundant in the central deep area in spring, when a phytoplankton bloom occurred. However, in autumn, L. strobila was abundant in the coastal shallow area. Boreal tintinnid Ptychocyli obtusa was found in spring. Both L. strobila and P. obtusa were concentrated in the surface waters when their abundance was more than 1 000 ind./L. Peaks of these species were in the subsurface waters when their abundance was less than 400 ind./L. This study showed that both high abundance and biomass of ciliates occurred in different areas in southern Yellow Sea seasonally. |

| 研究海洋浮游生物空间分布的季节性变化对于理解海洋生物发展进程极为重要。本研究于2006年春季（4月）和秋季（10月，11月）在南黄海（32°-36.5°N,122°-125°E）的中央深水区（站位水深>60 m）和近岸浅水区（站位水深<60 m）进行了浮游纤毛虫丰度和生物量的分布调查。调查显示：春季表层纤毛虫丰度（（1 490±2 336） ind./L）和生物量（（4.11±7.81）μg C/L）皆高于秋季（丰度：（972±823） ind./L，生物量：（1.11±1.18）μg C/L）。其中，近岸浅水区纤毛虫丰度和生物量的季节性差异不大；相比之下，中心深水区的春季表层纤毛虫丰度（（1 878±2 893） ind./L）和生物量（（5.99±10.10）μg C/L）均要高于秋季（丰度：（738±373） ind./L，生物量：（0.74±0.76）μg C/L）。因此在春季，纤毛虫丰度和生物量的高值区出现在中央深水区，而到了秋季则出现在近岸浅水区。我们在黄海中央深水区发现了大量混合营养型纤毛虫Laboea strobila，此时正值浮游植物赤潮爆发；而秋季L.strobila则主要分布在近岸浅水区。一种北方常见砂壳纤毛虫Ptychocyli obtusa仅在春季航次中出现。当这两种纤毛虫的丰度出现大于1 000 ind./L时，其峰值均出现在表层水体中；当丰度低于400 ind./L时，峰值则出现在次表层。本文表明，春、秋季南黄海浮游纤毛虫丰度和生物量在空间分布上存在差异。 |
