Emissions from International Shipping Vessels Contribute to Ocean Acidification

By ⋅ November 4, 2013 ⋅ One comment

Ship emissions of sulfur and nitrogen oxides (SOx, NOx) can be deposited and form sulfuric and nitric acid in surface water. Do heavily-trafficked trade routes result in “hotspots” of ocean acidification? Hassellöv and her team show “hotspots” that coincide with areas of heavy shipping traffic and seasonal stratification.
