After spotting a telltale red tinge to the water in the Elizabeth River, Christopher Moore, science advocate with the Chesapeake Bay Foundation, scoops up a water sample that will be later tested for the presence of algae. Adding a few drops of Lugol?s solution to the water helps the algae settle out of the water, so algal density can be determined. (Photo/Morgan Heim)
