The water was fairly turbid, I couldn’t see bottom in [...]

Nutrient inputs, especially nitrogen, remain primary challenge
A major new study comparing water quality and coverage of underwater grasses throughout Chesapeake Bay from 1984 to 2006 shows a clear link between the abundance of submerged aquatic vegetation (SAV) and levels of nitrogen in Bay waters. When nitrogen levels rise, [...]
