Abstract
The Japan Sea includes its own deep-water formation mechanics and a thermohaline circulation system similar to those of the Mediterranean Sea. Long-term trends of warming and decreasing oxygen concentration owing to global warming have been reported in the deep water of the Japan Sea. Although the minimum oxygen decrease rate of about 1000 m suggests a relatively active supply of new deep water to the depths, the overall deep-water formation has been stagnant since the 1970s throughout the water column. In addition to the gradual linear trends, interdecadal variation occurs in the temperature and oxygen concentration of the abyssal Japan Sea. The correlation between the interdecadal variation and the Arctic oscillation index indicates that the deep-water formation in the Japan Sea is modulated by Arctic oscillation via sea surface temperature in the East China Sea. This is an example of a teleconnection system on the marginal seas scale. For these reasons, we propose a collective name for this system: the Pacific Asian marginal seas system.
