River Respirators!

At a sea port in Savannah, Georgia, they are conflicted with their need for deeper river canals to keep up with the increasing size of cargo ships and their need to keep dissolved oxygen levels in the water high enough to continue to sustain aquatic life. This article talks about Savannah's plans to install a water bubbler, like in a home aquarium, to add oxygen to the water since the increased depth of the water will decrease the dissolved oxygen levels. This will be the largest scale project to oxygenate the waters of the Savannah River. Although their heads are in the right place, and they are thinking about the wild life as well, only time will tell if their efforts are effective.
