60 radiolarian species (14 Spumellaria and 44 Nassellaria) have been identified in the surface layer of the bottom sediments of the Arctic Ocean and its marginal seas. By comparing the radiolarian species lists from the Norwegian Sea, Okhotsk Sea, Bering Sea and the North Pacific it is possible to conclude that in the Arctic Ocean 48 species are common with the Norwegian Sea fauna, 52 with fauna of Okhotsk Sea and 56 are also distributed in the North Pacific. It was established, that the most diverse fauna was obtained in the area of the Fram strait (42 species) and in the Chukchi Sea (40 species). Both regions are probably areas of expatriation of the Norwegian Sea and Pacific Ocean faunas, respectively, because radiolarian species (and specimens) were found only in low numbers elsewhere in the Arctic Ocean. The radiolarian fauna of the Arctic Ocean is a derivative of the Atlantic fauna. The radiolarian species composition in the Arctic Ocean indicates that radiolarian fauna elements also migrate from the Pacific Ocean. However, the most abundant and widely distributed species of the Pacific assemblages are not found in the Chukchi Sea.
26 radiolarian species have been found in the deposits of the central Arctic Ocean basins, but only 8 species have a circumpolar distribution. The number of nassellarian species are 2-5 times higher than the number of spumellarian species, but the abundance of spumellarian skeletons are many times (4-38) higher, than for the nassellarian skeletons. However, in the bottom sediments of the marginal seas the abundance of nassellarian skeletons exceeds many times the number of spumellarian skeletons. No endemic radiolarian species are present in the Arctic Ocean.
The structure of the Arctic Ocean radiolarian associations are the same as in the closed and semiclosed epicontinental seas. Here there is a rather low species diversity and a high level of dominance of single species. Furthermore, the high rank taxa associations are characteristic for the different areas.
