Aquatic hypoxia can be a serious problem, producing oxygen-depleted "dead zones" in lakes or seas. New research suggests that a process known as downwelling may help keep those zones from forming – ...

Downwelling field experiment at Searsville Reservoir in Woodside, California, which shows the pipes through which oxygenated surface water is pumped into the depths to prevent the formation of ...

Could pumping oxygen-rich surface water into the depths of lakes, estuaries, and coastal ocean waters help ameliorate dangerous dead zones? New work says yes, although they caution that further ...
