Could Bubbling Oxygen Revitalize Dying Coastal Seas?

Coastal waters worldwide are rapidly losing oxygen, causing declines in marine life and affecting communities who rely on the health of coastal waters. Prominent examples of low-oxygen coastal waters are found in the Baltic Sea, for instance, where oxygen loss in recent decades has led to major ecosystem changes. Potentially toxic cyanobacterial blooms have become frequent and widespread, spawning grounds for cod have been greatly reduced, and f…
