在2000-2001年严冬之后的2001年夏季，在日本海观测到新形成的底层水。新的底层水，这是在日本海西北部观察到的低温，高盐度，高溶解氧和低营养盐浓度相比，旧的底层水。新底层水的分布表明，新底层水形成于海参崴以南海域，而不是43°N以北的日本海北方海域，并被平流输送到观测区。据推测，形成事件发生在2001年1月下旬至2月上旬，因为2001年2月中旬突然出现了速度超过8 cms-1的强气流。这一形成事件可能不仅有助于底层氧减少趋势的缓和，而且有助于日本海温盐环流的旋转。
The newly formed bottom water in the Japan Sea was observed in the summer of 2001 after the severe winter 2000–2001. The new bottom water, which was observed in the northwestern Japan Sea, showed low temperature, high salinity, high dissolved oxygen and low nutrients concentration compared to the old bottom water. The distribution of the new bottom water indicates that the bottom water was formed in the south off Vladivostok, not in the northern Japan Sea north of 43°N, and was advected to the observation area. It is suggested that the formation event occurred in the late January‐early February 2001, because strong flows of faster than 8 cms−1 appeared abruptly from mid‐February 2001. This formation event may contribute not only the relaxation of the oxygen‐decreasing trend in the bottom layer but also the spin‐up of the thermohaline circulation in the Japan Sea.
