• The analysis on modern marine ostracod assemblages in Suruga Bay, Central Japan revealed an "Ostracode Barren Zone" (OBZ) at the water depths of 645-910m, well within the Oxygen Minimum Zone (OMZ). The study is based on 131 surface sediment samples that cover the entire area of the bay. Among the 10 samples within OBZ, only three bear shells of intertidal to lower sublittoral zone ostracod species that are obviously allochthonous in nature; deep-sea species are all distributed outside OBZ, either above or across it. The reason that ostracods cannot survive in OBZ is possibly ascribed to the anoxic condition inside the OMZ (water depths ca. 650-1,200m, dissolved O_2 1.5-1.8ml/l).
