研究了1997年冬季的电导率-温度-深度数据，以确定日本海北部日本盆地东部存在中间水。在主斜斜和日本海正常水（UJSPW）上部之间的中间深度，可以用盐度极值探测到三种不同的水团。浅层盐度最大值和中层盐度最小值可分别识别为对马暖流和日本海中间水。温度高、溶解氧高、盐度较高的深层水为高盐度中间水（HSIW），其密度与UJSPW相似（27.30 ~ 27.33 σθ）。等平分析表明，高压高压从西伯利亚海岸向东南方向流动，在西伯利亚海岸，高压高压露头，并有机会通过直接冷却变得更密集。我们得出结论，TWCW是HSIW的起源，HSIW反过来又是UJSPW的来源。
Conductivity-temperature-depth data from the midwinter in 1997 are examined for the presence of the intermediate water in the eastern Japan Basin, in the northern part of the Japan Sea. Three different water masses can be detected with salinity extrema at intermediate depths between the main pycnocline and the upper portion of the Japan Sea Proper Water (UJSPW). The shallower salinity maximum and the middle salinity minimum can be identified as the Tsushima Warm Current Water (TWCW) and Japan Sea Intermediate Water, respectively. The deeper salinity maximum water, with high temperature and high dissolved oxygen, is identified as High-Salinity Intermediate Water (HSIW) and has density similar to UJSPW (27.30–27.33 σθ). Isopycnal analyses indicate that HSIW flows southeastward from the Siberian coast, where TWCW outcrops and has an opportunity to become denser by direct cooling. We conclude that TWCW is the origin of HSIW, which in turn, is a source for UJSPW.
