Abstract

Abstract

According to the survied data of nano- and microzooplankton in the Kongsfjorden area of Svalbard in August 2017, the species composition and community characteristics of nano- and microzooplankton in the region were analyzed. The results show that there is a clear thermodynamic layer in the Kongsfjorden area in the water depth of 10-50 m, which is higher than that of other water layers. The salinity gradually increases from the surface to the bottom, and the salinity of 70 m is basically stable in the deep sea. Nano- and microzooplankton includes three categories:Aloricate Ciliates, Tintinnida Ciliates and Crustacea Nauplii. Tintinnida Ciliates include 10 species. Ptychocylis obtuse, Acanthostomella norvegica, Favella sp., Tintinnopsis beroidea and Stenosemella nivalis are dominant species. Nano- and microzooplankton mainly distributes in the upper water. Species and abundance are rich in 10-30 m water layer. Nano- and microzooplankton abundance accounts for about 54.8% in upper 30 m water layers. And it's more than 93% in the above 100 m water layers. The most of abundance of nano- and microzooplankton (the mean is 343.3 ind./L) is in the 10 m layer, and the lowest (the mean is 50.9 ind./L) is in the bottom. The biodiversity is generally preferable and the differences between different sites are slight.
