Dead zones in the Chesapeake
Those large areas of Chesapeake Bay that don't have enough oxygen in the water to support happy critters or happy underwater grasses did not get much attention this past summer. In fact, at the beginning of summer, things looked fairly good. Hurricane Arthur stirred up the bay nicely. But every heavy rain also washes a lot of phosphorus and nitrogen into the bay. In the October issue of PropTalk, the dead zone was estimated to be about 1.32 cubic miles. The crab harvest of 2014 was certainly lower. The increasing aquaculture of oysters is a good effort to clean our waters as well as provide some tasty morsels at happy hour. But our bay is anything but happy.
