Because of the shallow nature of large areas of the estuary the focus is on water volume or cubic miles, instead of square mileage as used in the Gulf. Later this year, researchers will measure oxygen levels in both bodies of water. The forecast predicts a mid­summer low­-oxygen hypoxic zone of 1.97 cubic miles.

EO28), were identified in hydraulic fracturing flowback and produced water using a new application of the Kendrick mass defect and liquid chromatography/ quadrupole-time-of-flight mass spectrometry. Surfactants reduce the surface tension between water and oil, allowing for more oil to be extracted from porous rock underground.
