Researchers: Chesapeake Bay Dead Zones Biggest Since 2014

GLOUCESTER POINT, Va. (AP) — Researchers say the total amount of oxygen-deprived dead zones in Chesapeake Bay this summer was the biggest since 2014.
The Virginia Institute of Marine Science also said Monday that the total amount of dead zones this summer increased by 10 percent over last year.
