Short summary
The Arabian Sea and Bay of Bengal have low-oxygen zones which are harmful to marine life. The Arabian Sea low-oxygen zone expanded until 2013 but has since shrunk. We found more oxygen-rich water flowing in from the southern Indian Ocean, while local oxygen-poor water sources declined. However, higher oxygen consumption partly offsets this oxygen gain. Both shifts are tied to changes in Indian Ocean circulation and the time water spend in the region, likely related to global climate change.
