Still Cloudy, With a Chance of Clearing

The Chesapeake Bay is the largest estuary in the United States and third largest in the world. Once sculpted by
ice, water, and powerful geologic forces over tens of millions of years, today's Bay is shaped by human forces
During the past half century, the watershed (image below)
has become a landscape full of fast-spreading cities, suburbs, and farms. That development has clouded the water
and reduced the productivity of the habitat. Scientists have been monitoring the Bay closely since the 1980s,
and the news has often been troubling—waterways polluted with nitrogen and phosphorous, algae blooms, dead zones, and fish kills.
But glimmers of hope have begun to emerge, and efforts to clean up the Bay are starting to make a difference. The
gains so far are small, and only careful monitoring will help scientists sort out which aspects of the cleanup
are proving effective and which are not.
The series of stories and images below describes the natural and unnatural problems in the Chesapeake watershed,
which stretches from upstate New York to Newport News.
