 note = {This paper documents a radiolarian fauma in late winter (March 10, 2008) within surface subsurface waters (<100 m depth) in the Japan Sea off Tassha, Sado City, Sado Island, Niigata Prefecture, central Japan. The sea-water temperature at the sampling site (38°05' N, 138°10' E) is near-constant down to 100 m depth (9.6-9.7℃), which probably represents the lowest water temperature throughout the year. This water body with a uniform temperature is considered to have formed by the development of a surface mixed layer influenced by the strong northwesterly winter monsoon on the Japan Sea. Eleven spumellarian and 14 nassellarian species were identified from 583 recovered skeletons. The faunal composition is characterized by the dominance of cold-water spumellarians (Cyrtidosphaera reticulata and Larcopyle buetschlii) and spicule-type nassellarians (Neosemantis distephanus and Plectacantha cremastoplegma) with minor amounts of a warm-water dweller (Didymocyrtis tetrathalamus). Based on accumulated knowledge of the radiolarian ecology of living species off Sado Island, these findings can be explained in terms of the low water temperature preferred by cold-water species, the opportunistic appearances of spicule-type nassellarians, and weak inflow of the Tsushima Warm Current during winter.},
