Thank you for your comment regarding the conflicting dead zone reports by the Virginia Institute of Marine Science and the Maryland Department of Natural Resources. The MD DNR and VIMS reports vary due to different lengths in reporting periods, areas in which are monitoring and variations in the reporting model.
MD DNR monitors the hypoxic conditions in the Maryland portion of the Bay, while VIMS monitors the full Bay. VIMS stated, “The findings of the VIMS hypoxia model and Dead Zone Report generally match the monitoring-based report provided by the Maryland Department of Natural Resources for the Maryland portion of the Bay. Slight variations in results are due to different reporting periods and regions, as the Virginia report includes results for the full Bay from the onset of hypoxia in spring to its cessation in the autumn, while Maryland’s DNR focuses on Maryland conditions from June through September.”
