| 内容記述 | Radiolarians living in surface–subsurface waters (0–200 m depth) were documented from the Japan Sea off Tassha, Sado City, Sado Island, Niigata Prefecture, central Japan on 7 June 2010, along with water properties (temperature, salinity, and fluorescence intensity). Plankton samples were collected from two depth intervals (0–100 m and 100–200 m), and Rose Bengal staining was used to discriminate "living" from "dead" specimens. The temperature ranged from 8.9℃ to 10.5℃ at 100–200 m depth, and from 10.5℃ to 17.4℃ at 0–100 m depth. Salinity shows little variation at depths of 0–200 m, ranging from 34.1 to 33.7 psu. Fluorescence intensity shows a peak at around 54 m depth. The radiolarian fauna of the deeper sample (607-11SD-8; 100–200 m depth), from which 23 "living" and 15 "dead" specimens were obtained, consists mainly of cold-water species such as Larcopyle buetschlii and Cyrtidosphaera reticulata, along with Cladococcus bifurcus, Acanthosphaera circopora, and Phormacantha hystrix. The shallower sample (607-11SD-5; 0–100 m depth) contains 16 "living" and 2 "dead" specimens, including C. reticulata, L. buetschlii, and A. circopora, although the standing stock is very low. The existence of "living" specimens of L. buetschlii and C. reticulata at 100–200 m depth shows that these cold-water species are able to survive in deeper waters (>100 m depth) during the warm season in the central Japan Sea. The depth distributions of other species (e.g., A. circopora) in the subsurface water were also determined, providing ecological information on living radiolarians in the Japan Sea. | |||||
