Larger dead zone predicted for Chesapeake Bay
Scientists expect this year's summer Chesapeake Bay hypoxic or "dead zone"-an area of low to no oxygen that can kill fish and aquatic life-will be larger than average, approximately 1.89 cubic miles. This is due to spring rainfall amounts in New York and Pennsylvania that led to an above average Susquehanna River nitrogen load to the Chesapeake Bay this spring.
"Although the higher forecasts for this summer seem to buck a recent trend toward lower anoxic volumes in Chesapeake Bay, they are consistent with known links between high river flows and oxygen depletion," said Jeremy Testa, assistant professor at UMCES' Chesapeake Biological Laboratory.
