This American Geophysical Union article documents factors contributing to the enlargement of the Mississippi River delta dead zone as a result of the 1993 Mississippi River flood. Unusually high precipitation during the summer of 1993 in the Mississippi River basin resulted in hypoxic conditions of the coastal ocean, with elevated oxygen concentrations more widespread than usual along the Louisiana coastline west of the delta. The article describes the causes of this condition and features figures including satellite imagery from the dead zone.
