Summary
Hypoxia in York River was documented for the first time in the 1970s. It is associated with spring-neap tidal cycle. There has been little to no response in the benthos. Mobile fauna is avoiding the hypoxic areas.

Summary
Hypoxia in Rappahannock River was first recorded in the 1980s. Some anoxia occur in summer. Hypoxia has caused mortality of benthos (annual recolonization) and avoidance of mobile fauna.

Summary
Laguna Madre hypoxia was recorded for the first time in 1980s. The lowest dissolved oxygen is in the deep areas. Sewage and shrimp farming have added nutriets into the lower Laguna Madre. In the upper Laguna Madre stratification has significantly contributed to hypoxia.
