Smaller dead zone predicted for the Chesapeake Bay

Due to less "stuff" flowing into it this spring from the Susquehanna, some University of Michigan researchers and NOAA are forecasting a slightly below-average, but still significant dead zone in the Chesapeake this summer. Over the last decade, the size of the dead zone hasn't changed that much anyway. But 1.37 cubic miles is nothing to overlook.

The size of the Chesapeake Bay's dead zone has been measured annually since 1950. Low-oxygen regions also form each summer in the lower portions of the bay's major tributaries and episodically in many smaller tributaries.
