A team of researchers from the Arabian Center for Climate and Environmental Sciences (ACCESS) at NYU Abu Dhabi (NYUAD) studied the evolution of dissolved oxygen in the Arabian Gulf over three decades and discovered a significant decline in oxygen concentrations and the expansion of the seasonal near-bottom hypoxic zone (lower oxygen levels near the bottom of the Gulf in certain seasons). The researchers conclude that changes in local climate are altering the Gulf's physical and biogeochemical environment with potential implications for the ecosystems and the fisheries of the region.
