As a researcher who has been studying this topic over a decade, I am interested in learning more of this news. However, I have not been able to locate the source of this news yet. The Bottom Water oxygen concentration is still > 220 umol/kg in the East Sea and the oxygen consumption rate is < 1 umol/kg/yr. I am not sure how could they claim this would go to anoxic in 100 years even with complete shut off of deep water formation and without considering complex climate variability in the region.
