The Changing Chesapeake

February 1, 2013

The Chesapeake Bay receives water from the 64,000 square miles of land surrounding the bay and Landsat satellites are a critical and invaluable tool for characterizing the landscape and mapping it over time. Landsat data provides a baseline of observations for science about how human activities on the land affect water quality, affect wildlife habitat, affect air quality. Without it we wouldn’t be able to really understand how sources of nutrients and sediment have changed and where they are in the Chesapeake Bay.
