Study reveals missing drivers of ocean deoxygenation

Science
June 11 (UPI) -- Over the last 50 years, the amount of oxygen in the world's oceans has declined by 2 percent. Models designed to simulate the phenomenon, however, have failed to reproduce such significant losses. Now, scientists have identified the blind spots in current models, as well as drivers of ocean deoxygenation ignored or underestimated by popular simulations. One of the biggest drivers of ocean deoxygenation is global warming. As increases in the amount of CO2 have encouraged a greenhouse gas effect, heating the atmosphere, the ocean has warmed, too. Warmer water can't absorb as much gas. Rising ocean temperatures can explain approximately 20 percent of the ocean deoxygenation measured over the last half-century, and the current computer models account for this type of oxygen ...
