Climate Change May Also Be Contributing to Increasing Dead Zones in the Oceans
- "Scientists with NOAA and other agencies are also beginning to link expanding hypoxic or low-oxygen dead zones in the worlds oceans not only to nutrient runoff from farms and cities but also to climate change. As ocean surface temperatures rise (and they were the highest ever recorded in summer 2009) they create a thermal cap that makes it harder for the natural circulation of deep ocean water to the surface where its re-oxygenated by contact with the atmosphere." - excerpt from the Blue Notes #71 newsletter by David Helvarg of the Blue Frontier Campaign.
