Abundance and assemblages of dinoflagellates and ciliates were studied in water samples collected from three different depths at five locations in the Kongsfjorden, during summer (June 14–21, 2011) and fall (September 15–27, 2012). Generally, athecate dinoflagellates were ubiquitously dominant during both seasons. Surface dinoflagellates abundance ranged from 1.87 × 10³ cells/L (KF1) to 11.62 × 10³ cells/L (KF4) and column integrated abundance ranged from 20.3 × 10⁶ cells/m² (KF1) to 126 × 10⁶ cells/m² (KF2) during summer. Dinoflagellate abundance was relatively lower during fall ranging from 0.02 × 10³ cells/L (KF5) to 0.66 × 10³ cells/L (KF3) at surface, and correspondingly, a low column integrated abundance ranging from 2.34 × 10⁶ cells/m² (KF5) to 19.1 × 10⁶ cells/m² (KF1) was observed. Amphidinium sp., Gyrodinium fusiforme, Gyrodinium estuarile dominated during summer, while Gymnodinium sp. was dominant during fall. Among ciliates, aloricate ciliates were more dominant than loricates. Ciliates at surface ranged from as low as 0.069 × 10³ cells/L (KF1) to 3.69 × 10³ cells/L (KF4) during summer. Ciliate abundance increased with depth (up to 20 m). Strombidium spp. (55.28%) and Mesodinium rubrum (36.66%) were dominant during summer. Among the loricates and the aloricates, Strombidium spp. (85.72%) and Tintinnid spp. (92.15%) dominated in fall. The presence of dominant aloricates with characteristic cleptochloroplasts reflected high grazing activity in these waters during both seasons. Diversity study indicates that the dinoflagellates and ciliates are well represented during both seasons. Statistical analyses of the dinoflagellates and ciliates with hydrographic data do not show dominant role of any hydrographical parameters on their diversity, and the same is discussed vis‐à‐vis Atlantification of the fjord.

斯瓦尔巴群岛Kongsfjorden的鞭毛虫和纤毛虫的空间和季节变化

在夏季（2011年6月14日至21日）和秋季（2012年9月15日至27日）从Kongsfjorden五个地点的三个不同深度采集的水样中研究了鞭毛藻和纤毛虫的丰度和集合。通常，在两个季节中，无鞭毛的鞭毛虫无处不在。表面鞭毛虫的丰度范围为1.87×10 ³ 格/ L（KF1）至11.62×10 ³ 格细胞/ L（KF4），柱积分丰度范围为20.3×10 ⁶ 格细胞/ m ²（KF1）至126×10 ⁶ 格/细胞夏季m ²（KF2）。秋季鞭毛藻的丰度相对较低，范围从0.02×10 ³ 细胞/ L（KF5）到0.66×10 ³ 在表面上 每平方公尺（KF3），并且相应地，观察到的低柱积分丰度范围为2.34×10 ^6单位/ m ²（KF5）至19.1×10 ^6单位 / m ²（KF1）。在夏季，Amphidinium sp。，fusforme Gyrodinium fusiforme和gyrodinium estuarile占主导，而Gymnodinium sp。在秋季占主导地位。在纤毛虫中，有藻的纤毛虫比纤毛虫更占优势。夏季的表面纤毛从低至0.069×10 ³ 格/ L（KF1）到3.69×10 ³ 格/ L（KF4）。纤毛虫的丰度随深度（最大20 m）而增加。急游虫属。（55.28％）和夏季，中型红宝石（36.66％）占主导地位。在叶状体和叶状体中，Strombidium spp。（85.72％）和Tintinnid spp。（92.15％）以秋季为主。在两个季节中，这些水域中具有特征性叶绿体的优势叶酸存在。多样性研究表明，在两个季节中，鞭毛虫和纤毛虫都有很好的代表性。用水文数据对食鞭毛和纤毛虫的统计分析并未显示任何水文参数对其多样性的主导作用，关于峡湾的大西洋化也讨论了同样的问题。
