通过使用日本在鄂霍次克海纬度55°N以南获得的所有水文数据，我们编制了一个数据集。研究结果表明，千岛盆地存在大量的密度范围为26.8 ~ 26.9 σθ的较冷、新鲜、富氧的均匀的中间水，我们称之为千岛盆地中间水（KBIW）。电子等排分析结果表明，KBIW的可能起源地位于鄂霍次克海西南部的北海道沿岸。我们认为，KBIW是由相对密集的大豆温暖的水，这只出现在早春，与冷，新鲜的水，来自鄂霍次克西北部的等密度混合。最后，我们证明KBIW可能是北太平洋中层水（NPIW）的源水，因为它具有相同的密度范围和水的性质。
By using all Japanese hydrographic data obtained south of 55°N in latitude in the Sea of Okhotsk, we compile a data set for this study. Our investigations with these data show that a large quantity of relatively cold, fresh, oxygen-rich homogeneous intermediate water with a density range of 26.8 to 26.9 σθ exists in the Kuril Basin; we name this intermediate water the Kuril Basin Intermediate Water (KBIW). Results of isosteric analyses show that a possible origin of KBIW is located in a region off the Hokkaido coast in the southwestern Sea of Okhotsk. We suggest that KBIW is produced by the isopycnal mixing of relatively dense Soya Warm Water, which appears only in early spring, with the colder, fresher water which originates from the northwestern Okhotsk. Finally, we demonstrate that KBIW may be a source water of the North Pacific Intermediate Water (NPIW) because it has the same density range and water properties.
