摘要：

Weakening of the abyssal circulation (conveyor belt) in the Japan Sea during the 20th century is deduced from the decreasing trend of bottom dissolved oxygen (O-2). This trend indicates a shortened O-2 supply, caused by too inactive conveyor belt to compensate for biological O-2 consumption at the bottom of the sea. Recent climatic changes during the winter season in the northern Japan Sea may play a significant role in prohibiting the formation of surface seawater dense enough to sink to the bottom. It is predicted that the Japan Sea bottom water will become anoxic within a few hundred years, as it was in the last glacial maximum.
