A new study led by researchers at the Virginia Institute of Marine Science reveals that land use in the watersheds from which this «dissolved organic matter» originates has important implications for Bay water quality, with the organic carbon in runoff from urbanized or heavily farmed landscapes more likely to persist as it is carried downstream, thus contributing energy to fuel low - oxygen «dead zones» in coastal waters.
